The SC PRO Series embodies the latest and greatest system design technologies in an all-new housing design. Developed upon feedback directly from customers and installers, the unit incorporates a variety of high-end components at an affordable price point. By combining powerful airflow with quiet operation technology, the SC PRO is unrivaled when it comes to efficiently cool small to mid-sized wine cellars.

What separates the original SC Series from the SC PRO Series? The SC PRO comes complete with a new, blower fan system that optimizes performance while operating at a significantly lower noise level. It also reintroduces a condensate management system, which effectively evaporates up to 3oz. of water an hour. This management system renders the drain line as an additional safeguard rather than a definite need.

The SC PRO Series will be a direct replacement for the SC Series, and its predecessor, one of the most well-known cellar cooling units, the XLT.

BTU/H Rating


The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.) which do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature.


Cellar Size:

Approx. 1000 cu. ft. when cellar is fully insulated and sealed with proper vapor barrier (each wine cellar is unique and has specific cooling requirements; heat load calculations should always be performed prior to selecting a cooling unit)

BTU/h w/85°F air entering condenser coil:



17.5"L x 14.25"W x 15.75"H





Voltage Rating:

115V (20-amp dedicated circuit required); 230V (subject to availability)


65 lbs


3.7 (running amps)

Drain Line:

1/2" ID clear plastic tubing


Through-the-wall, partially ducted


Advanced digital controller, liquid-temperature-measuring bottle probe (retractable cable)

Temp. Delta:

Can maintain a 55°F cellar temperature with up to 85°F condenser air intake temperature

Ducting Options:

Exhaust air can be ducted using the optional ducting kit


Two-year limited warranty (parts and labor) / Five-year limited warranty (compressor)

Karen Yeager
Great unit

This unit replaced an undersized previous unit by a different manufacturer. Very easy to modify space and immediately saw many differences and improvements in the WhisperKool, It is working great.

Bertil Wolf

The fan was hitting and required adjusting. Had to put slight upward pressure to prevent fan hitting and retightened the screws. Seems fine now.

WhisperKOOL SC PRO 4000 - Great Support

I contacted WCHQ through its website to get information on a self-contained unit. Milan Pavlovic responded immediately and, from the information I provided on the size and location of my wine cellar, confirmed the selection of the WhisperKOOL SC PRO 4000 unit. It was clear Milan was well-experienced with self-contained cooling units, listened carefully to my circumstances, asked the right questions to assure he understood my objectives for the cellar – and provided an objective recommendation. Once I ordered the unit, Milan kept me informed on the delivery schedule – in fact the cooling unit was delivered in one day – completely unexpected. WCHQ has an outstanding representative in Milan Pavlovic – professional, highly knowledgeable, top-end communication and, most importantly, committed to his customers.

Caller cooling

It’s a great unit hands down, what more can I say.


Although it took a while to receive my order, I was able to get updated information about the reason for the delay. Also, the information that I was given was accurate and the time frame was actually less than I was told

This cooling unit can be classed as Self-Contained. It's a Through the Wall unit, so it sends exhaust fumes into an adjacent room.

Our range includes both Small and Large sized units.
