SIDE MOUNT COOLING UNITS
Our DTS 3021 (NEMA Type 12) indoor cooling units are ideal for small enclosures and for the cooling of hot spots in larger control cabinets. Housing: galvanized sheet steel. Cover: electrostatically powder coated RAL 7035 (light grey); for ANSI 61 grey use part no. ending in …251
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.
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.
Powder coated steel or stainless steel cover designed for manufacturing environments. Easily painted to match enclosure or machine.
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.
