Extreme Series 3500tIR Wall Mounted | WhisperKOOL

 • There are three different versions of our extreme units:

Extreme tiR fully ducted (FD): This product is intended for fully ducted installations. Fully ducted units are for customers who don’t want to see their unit in the cellar. The duct plenums for the evaporator and condenser will be included with your purchase. This unit also comes with a KDT Plus remote controller and thermostat. The controller can be mounted outside the cellar, allowing you to monitor your cellar temperature without needing to enter. The controller can be mounted up to 50 feet away from the Extreme unit.

Note: If you are planning to place this unit in the attic and use ducting, please contact our sales team for pricing. You may not need ducting equipment for the condenser side of the system.

Extreme tiR Self Contained: This product is intended for through-the-wall installations. It is an “upgrade” to the Extreme ti because it uses the KDT Plus remote controller and thermostat. The duct plenums for the evaporator and condenser can be purchased separately. The controller can be mounted outside the cellar, allowing you to monitor your cellar temperature without needing to enter. The controller can be mounted up to 50 feet away from the Extreme unit.

Note: If this unit will be installed through an exterior wall, you will need to purchase an exterior housing to protect the unit. If this unit will be installed through an interior wall, the hot air exhaust may be redirected to another location using the condenser ducting plenum kit.

Extreme ti: This product functions in the same way as the tiR and is intended for through-the-wall installation. The difference between the ti and tiR is that the controller and display will be located on the front face of the unit. In order to monitor your cellar conditions, you will need to physically enter your cellar.

Note: Self-contained units require adequate ventilation on the exhaust side of the unit to dissipate the heat generated during operation.

 • Available 24V Thermostat Conversion Kit Option options: No Thermostat, With 24v Thermostat
