Why Choose the WhisperKOOL Mini Blow-Through System?
Concealed Cooling for Modern Wine Cellars
The Mini Blow-Through is designed for installations where the cooling equipment should not compete with the cellar's architecture. It can be positioned in a soffit, ceiling cavity, custom cabinet, attic, cellar enclosure, or adjacent mechanical space while directing conditioned air into the wine cellar.
Three Airflow Configuration Options
The evaporator can be configured for fully ducted, fully ductless, or hybrid airflow. This allows the supply and return paths to be adapted to the available installation space, architectural design, register placement, and service-access requirements.
Liquid-Temperature Bottle Probe
The included bottle probe measures liquid temperature instead of relying only on rapidly changing ambient air temperature. This helps the controller respond to temperature changes in a way that better reflects the thermal condition of the stored wine.
Remote Digital Control
The KDT digital display can be installed remotely using the supplied 50-ft. display cable. It provides system control, temperature information, and advanced system-protection alerts without requiring the evaporator to remain visible.
Built-In Condensate Management
The evaporator includes an internal condensate pump to assist with moisture removal. A properly routed drain line is still required, and condensate operation must be tested during commissioning.
Two-Speed Airflow Control
The Mini Blow-Through evaporator includes a two-speed fan switch. Higher airflow can increase cooling output and air circulation, while the lower setting may reduce airflow sound where the installation allows it.
Service-Friendly Construction
Dual-side service access, configurable line-set routing, removable components, upward-facing connections, and accessible electrical connections help simplify installation and future maintenance.
Flare Connection Design
The refrigerant piping connections are designed to support properly prepared flare fittings. Correct cutting, deburring, flaring, lubrication, torque, evacuation, pressure testing, charging, and leak testing remain the responsibility of the qualified installer.
Ideal Applications
- Luxury residential wine cellars
- Glass-enclosed wine rooms
- Built-in wine walls
- Custom wine cabinetry
- Overhead soffit installations
- Adjacent mechanical-room installations
- Restaurant wine displays
- Hospitality and tasting-room projects
- Custom millwork installations
- Projects with restricted equipment visibility
- Applications requiring flexible supply and return airflow
Who This System Is For
This system is a strong fit for buyers and project teams who:
- Want the wine cellar cooling equipment concealed from view
- Need more airflow flexibility than a traditional through-the-wall system provides
- Are building a wine wall, cabinet, soffit, or custom millwork enclosure
- Need separate evaporator and condenser placement
- Have access to a qualified HVAC/R installer
- Can provide proper cellar insulation and a continuous vapor barrier
- Want liquid-temperature monitoring through a bottle probe
- Need a compact split-system solution for a challenging installation
Who Should Not Choose This System?
This product may not be appropriate when:
- A simple plug-in or through-the-wall cooling unit is required
- Professional HVAC/R installation is not available
- The wine room is not insulated, sealed, or protected by a proper vapor barrier
- There is no viable path for refrigerant piping, drainage, power, or control wiring
- The condenser would be installed in a small, unventilated indoor enclosure
- The project cannot provide the required airflow through registers or louvers
- The system is being selected only from nominal room volume without a heat-load calculation
- Required service clearances cannot be maintained
Required Airflow Configuration Kit
One airflow kit must be selected. The correct kit depends on whether the supply and return air will be connected to ductwork, discharged directly through deflectors, or arranged as a combination of both.
| Configuration | Kit Components | Best Application |
|---|---|---|
| Ducted Airflow Kit | 2 duct plenums | Both supply and return air are connected to insulated ductwork. Appropriate when the evaporator is positioned away from the cellar openings or when register placement requires separate duct runs. |
| Ductless Airflow Kit | 2 airflow deflectors | Supply and return air are directed from the evaporator without full duct runs. Appropriate for soffits, cabinetry, and concealed in-cellar placements with properly aligned openings. |
| Hybrid Airflow Kit | 1 duct plenum and 1 airflow deflector | One side is ducted while the other uses a directional deflector. Appropriate when only the supply or return requires ducting. |
The Blow-Through configuration documentation illustrates multiple supply and return orientations, including front, rear, downward, fully ducted, and mixed ducted/deflector arrangements. The installer must select the final configuration before cutting register openings or mounting the evaporator.
Airflow Configuration Guide
Fully Ducted Configuration
In a fully ducted installation, both supply and return air are routed between the evaporator and the cellar through insulated ductwork. This can provide the greatest freedom in equipment placement, but the duct design must remain within the manufacturer's airflow and run-length requirements.
Ductless Configuration
In a ductless configuration, directional deflectors route the return and supply airflow through aligned openings in the soffit, cabinet, or enclosure. The available arrangements permit the airflow to face forward, backward, or downward depending on the installation.
Hybrid Configuration
A hybrid configuration uses a duct plenum on either the supply or return side and a deflector on the opposite side. This option is useful when one airflow path can discharge directly while the other must be routed to a separate register location.
Optional Add-Ons
| Optional Add-On | Purpose |
|---|---|
| 24V Thermostat Conversion Kit | Allows the system to operate with a compatible third-party 24V thermostat. The thermostat must be properly located within the wine cellar and wired according to the appropriate pump-down control instructions. |
| Exterior Enclosure for OMEGA Condenser | Required when the OMEGA condensing unit is installed outdoors. The enclosure helps protect the condenser from outdoor exposure. |
| Ducting Kit for OMEGA Condenser | Used when the OMEGA condenser is installed indoors and condenser airflow must be ducted to and from an appropriate ventilated location. |
| Condenser Coil Coating | Provides added coil protection for applications where the condenser may be exposed to corrosive or demanding environmental conditions. |
KDT Controller vs. Optional 24V Thermostat Control
| Feature | KDT Controller | 24V Thermostat |
|---|---|---|
| Primary Temperature Measurement | Liquid-temperature bottle probe | Thermostat air sensor |
| Remote Monitoring | Not included | May be available with a compatible smart thermostat |
| Advanced System Protection Alerts | Included | Not provided through the third-party thermostat |
| Humidity Control Integration | Not included | Potentially available with a compatible thermostat and field design |
| WhisperKOOL Warranty | Included with the system when warranty requirements are satisfied | The thermostat itself is covered by its manufacturer, not WhisperKOOL |
The KDT configuration is best for buyers who prioritize bottle-temperature sensing and system-specific protection alerts. The 24V conversion option may be preferred when compatible remote-monitoring or third-party thermostat functionality is required.

| 80 ft. | 3.05 lbs |
| 90 ft. | 3.20 lbs |
| 100 ft. | 3.35 lbs |
Register and Louver Requirements
Decorative registers and custom wooden grilles must provide sufficient free area for unrestricted airflow. Restricted openings can reduce cooling performance, increase airflow noise, raise static pressure, contribute to evaporator icing, and shorten system life.
- Registers and louvers should provide approximately 50% to 65% free open area.
- Do not install restrictive mesh, screens, acoustic foam, or solid backing behind the register.
- Account for the effect of paint, stain, sealant, and finishing materials on the final slot opening.
- Maintain consistent open area across the register face.
- Confirm the final design before fabrication or installation.
- Keep supply and return airflow unobstructed by racking, trim, framing, or stored bottles.
Free area can be estimated by multiplying the total register face area by the required open-area percentage. The project designer and installer are responsible for confirming that customer-supplied grilles comply with the manufacturer's airflow requirements.
Linear Register and Ducting Considerations
Linear registers must be selected with enough open-air area to support the system's airflow. Narrow decorative slots can appear large while still providing insufficient free area.
- Linear registers should generally be at least 48 in. long when used for these applications.
- Supply and return openings must provide adequate total free area.
- Restrictive internal diffusers may need to be removed when directed by the applicable installation guidance.
- Use properly sized branch fittings where ductwork serves multiple register locations.
- Insulated ductwork must be supported to prevent sagging and stress on the evaporator collars.
- Each 90-degree duct bend reduces available airflow and should be minimized.
- All duct joints must be mechanically secured and sealed against leakage.
Wine Cellar Construction Requirements
Cooling-system performance depends on the quality of the wine cellar enclosure. A cooling unit cannot compensate for an improperly constructed room.
Insulation
All walls and ceilings must be insulated. Higher insulation values reduce heat gain, system runtime, and operating cost. The supplied installation documentation identifies R-13 as a minimum reference, with higher values preferred for walls, ceilings, and exterior assemblies.
Vapor Barrier
A continuous vapor barrier is required on the warm side of the wine cellar assembly. Cuts, fasteners, conduit penetrations, seams, wall openings, and transitions must be sealed to prevent warm, moist air from entering the cooled enclosure.
Cellar Door
The cellar should use a properly insulated exterior-grade door with weather stripping on all sides and an effective bottom sweep or threshold. Air leakage around the door can cause extended runtime and difficulty maintaining the target temperature.
Glass-Enclosed Cellars
Glass has a lower insulating value than a conventional insulated wall. Glass quantity, glass type, exposure, room size, and surrounding ambient temperature must be included in the heat-load calculation.
Evaporator Installation Requirements
- Confirm the voltage shown on the evaporator nameplate before installation.
- Provide a dedicated 15-amp electrical circuit.
- Do not use a GFCI/GFI outlet or breaker unless specifically required and approved for the installation.
- Mount the evaporator high in the cellar or in the planned soffit location.
- Provide a structurally supported platform capable of carrying the operating weight.
- Maintain at least 12 in. of front service clearance.
- Install the supplied exterior insulation blanket before placing the evaporator in the soffit or enclosure.
- Add the required surrounding fiberglass insulation where the unit is exposed to an attic or warm cavity.
- Do not cover service panels, drain connections, wiring access, knockouts, or duct collars.
- Keep the evaporator level from side to side and front to back.
- Route and seal refrigerant lines, drain piping, power, display cable, and bottle-probe cable.
- Provide unobstructed supply and return airflow.
Condenser Installation Requirements
- Provide a dedicated electrical circuit matching the condenser nameplate.
- Install the condenser in a location with adequate heat rejection.
- Do not place an unducted condenser in a small, unventilated closet.
- Maintain the required service and airflow clearance around the condenser.
- Use the exterior enclosure when the OMEGA condenser is installed outdoors.
- Use the compatible ducting arrangement when an indoor installation requires ducted heat rejection.
- Keep condenser intake air within the manufacturer's permitted operating conditions.
- Install the condenser level and securely supported.
- Allow the condenser to remain upright before start-up if required after shipment.
The installation documentation states that the system is designed to maintain approximately 55°F cellar conditions when the application is properly designed and the condenser entering-air temperature remains within the stated operating range. Excessively warm condenser air reduces cooling capacity and may shorten system life.
Pump-Down System Operation
The system uses a refrigeration pump-down control sequence. When cooling is required, the liquid-line solenoid opens and refrigerant pressure allows the condensing unit to start. When the controller is satisfied, the solenoid closes and the compressor continues operating until the low-side pressure drops to the cutout setting.
Pump-down operation stores most of the refrigerant on the high side when the system is off. This control arrangement must be installed and commissioned according to the appropriate WhisperKOOL wiring and refrigeration diagrams.

Frequently Asked Questions
What is the WhisperKOOL Mini Blow-Through OMEGA system?
It is a split wine cellar cooling system consisting of a compact Mini Blow-Through evaporator and a separate OMEGA 110V H.E. air-cooled condenser. The evaporator conditions the cellar air, while the remote condenser rejects the collected heat.
How large of a wine cellar can the Mini Blow-Through cool?
The manufacturer documentation identifies an approximate capacity of up to 500 cubic feet when the cellar is fully insulated, properly sealed, and protected by a continuous vapor barrier. A heat-load calculation is still required because glass, ambient temperatures, doors, lighting, and construction materials can change the actual capacity requirement.
Does this product require an airflow kit?
Yes. One compatible airflow kit must be selected: the ducted kit with two duct plenums, the ductless kit with two airflow deflectors, or the hybrid kit with one plenum and one deflector.
What is the difference between ducted, ductless, and hybrid airflow?
A ducted configuration connects both supply and return air to ductwork. A ductless configuration uses directional deflectors for both airflow paths. A hybrid configuration ducts one side and uses a deflector on the other.
Can the Mini Blow-Through be hidden in a soffit?
Yes. Soffit installation is one of its intended applications. The soffit must be structurally capable of supporting the unit, provide the required front service clearance, contain properly aligned supply and return openings, and allow the evaporator to be fully insulated and serviced.
Can it be used for a glass wine cellar or wine wall?
Yes, provided a professional heat-load calculation confirms the required capacity. Glass typically creates more heat gain than insulated walls, so the quantity, type, and exposure of the glass must be considered during system selection.
Is the condensate pump included?
The evaporator is equipped with an internal condensate pump. A correctly routed discharge line is still required, and condensate drainage must be tested during installation and commissioning.
Does the system include a bottle probe?
Yes. The standard KDT configuration includes a liquid-temperature bottle probe with a 50-ft. cable. The probe is intended to measure the temperature of liquid in a bottle rather than only the surrounding air.
Can I use a smart thermostat?
A compatible smart thermostat may be used when the optional 24V thermostat conversion kit is selected and correctly installed. Third-party thermostat features and warranty coverage are provided by the thermostat manufacturer.
What is the difference between the KDT controller and a 24V thermostat?
The KDT controller uses the supplied bottle probe and provides WhisperKOOL system-protection alerts. A 24V thermostat typically measures air temperature and may offer remote connectivity, depending on the selected thermostat.
Can the OMEGA condenser be installed outdoors?
Yes, but the compatible OMEGA exterior enclosure is required for an outdoor installation. The condenser must be level, securely supported, and installed according to the applicable clearance and environmental requirements.
Can the OMEGA condenser be installed indoors?
Yes, provided the installation offers sufficient heat rejection. An indoor installation may require the compatible condenser ducting kit. The condenser should not discharge heat into a small, unventilated closet or enclosure.
What electrical service does the system require?
The Mini Blow-Through evaporator and OMEGA condenser require electrical service that matches their respective nameplates. The supplied documentation calls for dedicated 15-amp circuits for the Mini system components.
How far can the condenser be installed from the evaporator?
The condenser can be installed up to approximately 100 line feet from the evaporator, subject to correct line sizing, vertical-rise requirements, oil-management practices, refrigerant charging, and manufacturer installation instructions.
What line-set sizes are required?
The liquid line is generally 1/4-in. OD. The suction line is generally 3/8-in. OD for runs up to 50 ft. and 1/2-in. OD for runs over 50 ft. up to the permitted maximum. The installer must verify the final piping design against the current manual.
Does the system arrive fully charged?
The split system requires field evacuation, leak testing, charging, and commissioning. The supplied charge chart provides approximate initial charge values, but the final charge must be established by a qualified HVAC/R technician using proper operating measurements.
Is professional installation required?
Yes. This split refrigeration system must be installed by a qualified, licensed HVAC/R technician. Improper installation can cause refrigerant leaks, water damage, insufficient cooling, equipment failure, and loss of warranty coverage.
What cellar construction is required?
The cellar must be fully insulated, tightly sealed, and protected by a continuous vapor barrier. The door must seal correctly, and penetrations through the enclosure must be sealed against air and moisture infiltration.
How much free area should custom registers provide?
The manufacturer's airflow bulletin calls for approximately 50% to 65% free open area. Restrictive slats, mesh, screens, backing materials, or heavy finish buildup should not reduce the opening below the required airflow level.
How often should the system be maintained?
Annual professional preventive maintenance is recommended. Maintenance should include inspection of the coils, condensate system, drain line, pump, electrical components, airflow, refrigerant operation, controller probes, and bottle probe.
How is the split-system warranty activated?
The installing certified HVAC/R technician must complete and submit the required split-system warranty checklist with the requested installation, charging, electrical, drainage, and start-up data. Warranty activation is subject to WhisperKOOL review and approval.
Important Product Selection Notice
Wine cellar cooling capacity cannot be determined accurately from room volume alone. Before ordering the WhisperKOOL Mini Blow-Through OMEGA 110V H.E. system, confirm the cellar construction, glass exposure, ambient conditions, desired temperature, insulation, vapor barrier, condenser location, airflow configuration, electrical service, drainage path, refrigerant piping route, register free area, and service clearances.
Final system selection and installation design should be reviewed by a qualified wine cellar professional and licensed HVAC/R technician.
