Who This System Is Designed For

Best For:

• Fully insulated residential wine cellars
• Warm garage or mechanical room installations
• Cellars between 800 and 2,000 cu. ft.
• Homeowners who want temperature monitoring outside the cellar
• Installations where split systems are not practical

Who Should Not Use This System

This system is not recommended for:

• Unsealed basements or unfinished rooms
• Glass-heavy cellars without professional heat load calculation
• Cellars larger than 2,000 cu. ft.
• Exhaust areas exceeding 110°F intake temperature
• Installations requiring ultra-quiet evaporator operation in living spaces

If your project exceeds these constraints, a split system may be more appropriate.

Customer Review WhisperKOOL Extreme Series

Model Comparison

*Assumes a properly insulated and sealed wine cellar with vapor barrier. Heat load calculation is strongly recommended.

What Makes the Extreme tiR Different

The “tiR” models are the upgraded version of WhisperKOOL’s Extreme ti systems.

ti vs tiR Comparison

The tiR allows you to monitor and adjust temperature without entering the cellar.

Core Performance Features

Variable-Speed Fans

Adjustable-speed fans improve airflow control and help maintain stable cellar temperatures under varying load conditions.

Extreme Environment Operation

The Extreme tiR can operate with condenser air intake temperatures up to 110°F, making it suitable for:

• Garage installations
• Mechanical rooms
• Warmer climates

Bottle Probe Accuracy

The liquid-temperature measuring probe tracks the temperature of the wine itself rather than ambient air, improving temperature precision.

Through-the-Wall Installation

Designed to fit between standard 16” on-center studs with minimal structural modification.

Installation Requirements

Proper installation is critical to system performance.

Required Conditions:

• Fully insulated enclosure (minimum R-19 walls recommended)
• Continuous vapor barrier (6 mil polyethylene or equivalent)
• Dedicated 115V 20-amp circuit (230V subject to availability)
• 1/2" ID drain line (not included)
• Exhaust environment must not exceed 110°F

Failure to properly seal and insulate the cellar may result in:

• Inability to maintain 55°F
• Excessive compressor runtime
• Premature system failure

Ducting & Venting Options

• Condensing side can be ducted
• Designed for through-the-wall installation
• Exterior venting allowed if intake does not exceed 110°F
• External grille recommended for exterior installations

Always verify maximum duct length during planning to prevent airflow restriction.

Optional 24V Thermostat Conversion

An optional 24V conversion kit allows integration with compatible third-party smart thermostats.

Important:

• WhisperKOOL does not supply smart thermostats
• Selecting this option replaces the standard WhisperKOOL controller and bottle probe
• WhisperKOOL does not provide support for third-party thermostat issues
