DTS 3021/31/SS
900 - 1300 Btu/h
Closed Loop Design
Designed to isolate the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet.
Thermal Overload Protection
Compressor and fan motors are outfitted with integral temperature switches to shut down the unit in the event of excessive temperature. This increases the operating life of the compressor by preventing thermal overload trips.
Thermal Expansion Valve
Regulates the flow of refrigerant based on thermal demand for efficient performance over the entire operating temperature range.
Hermetically Sealed Compressor
The absence of any refrigerant
fill valves eliminates leak paths. Recharging is never needed. 100% cooling capacity efficiency is ensured.
Condensate Drain Port
Permits effective collection and drainage of condensation.
COOLING UNITS
The DTS 3021/31/SS series cooling units are ideal for small enclosures and for the cooling of hot spots in larger control cabinets. These units are particularly suited for the food industry and outdoor applications. Available in 3 models; DTS 3021 (NEMA Type 12) for indoor use, DTS 3031 (NEMA Type 3R/4) designed for outdoor use, and the stainless steel DTS 3031 SS (NEMA Type 4/4x) designed for wash-down applications.
ERP Efficiency Certified
As a component of the Kyoto Protocol to reduce carbon monoxide emissions, the European Energy Related Products (ERP) Directive includes an efficiency rating for fans. Pfannenberg proudly utilizes components which adhere to these requirements.
Rugged Design
Powder coated steel
or stainless steel cover designed for manufacturing environments. Easily painted to match enclosure or machine.
Environmentally Friendly
Utilizes HFC-free R134a refrigerant versus a blended refrigerant for easier service and minimized negative impact to the environment.
Highest in Class Capacity
The compact, 7 inch width is ideal for small enclosures with a relatively small heat load.
