WKSL Series systems are designed for easy installation by any, properly equipped and qualified air conditioning or refrigeration service technician. Two copper tubes and low voltage wiring
connect the two modules and power is hard wired to the units using adequately sized 110 AC volt electrical sources. These systems must be charged with refrigerant during installation. The WKSL series uses the Sentry III+ digital control system for complete control of the enclosure conditions.
There are two models to choose from: All units are 115 Volt, 60 Hz.

When our self-contained series will not meet your needs then the WKSL split design will provide the flexibility needed to create an ideal installation or deal with unusual site problems. The WKSL Series cooling systems are special split systems that allow mounting of the cooling (evaporator) module in the enclosure to be cooled and the exhaust (condenser) module as far as 50 feet away. The systems are designed to, when installed in a properly constructed enclosure provide a constant selectable temperature between 48° and 63° Fahrenheit while maintaining 50 to 75 percent relative humidity.
The WKSL 4000 is shipped from the factory with the unit configured with the cold air routed out the front (standard) with the option of routing the cold air out the top by the installer.
