Pfannenberg DTS Series Cooling Units - Side Mount

Large distance between intake and exhaust vents, safe circulation within the electrical enclosure due to long passage of air, therefore hot spots are eliminated
Maintains a UL Tested NEMA Type 12 seal against enclosure
UL 484 Listed, category ACVS, UL file #SA10300, CE approved for European use
Standard Controller (SC) with active alarm and door contact input
Powder coated steel cover for rugged environments, easily painted to match enclosure or machine
Condenser with 3 mm fin spacing, highly effective protection against strongly contaminated and aggressive ambient air
Active condensate evaporation system
Utilizes a thermal expansion valve (TXV) to ensure maximum performance over a broad range
