Pfannenberg 13383939158 DTS 3681 Cooling Unit, 230 V

Pfannenberg, 133 8393 9158, DTS 3681 Side Mount Cooling Unit, 230 V

DTS 3681 (NEMA Type 4/4x) stainless steel cooling unit have the largest capacity at almost 2 Tons. These unit are ideally suited for high temperature, high ambient environments. Housing: stainless steel 304.

Features:

• 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.
• Thermal Expansion Valve. Regulates the flow of refrigerant based on thermal demand for efficient performance over the entire operating temperature range.
• Closed Loop Design. Designed to isolate the external ambient air from the internally conditioned air eliminating the risk of contaminants entering the cabinet.
• Hermetically Sealed Compressor. The absence of any refrigerant fill valves eliminates leak paths. Recharging is never needed. 100% cooling capacity efficiency is ensured.
• Pressure Overload Protection. High pressure cutout switch ensures safety by shutting off the compressor in the event of excessive pressure appearing in the refrigeration circuit.
• High Cooling Capacity. The largest capacity cooling unit for high heat load requirements. High cfm fan on evaporator side for generous air movement through the enclosure.
• Corrosion Protection. Outdoor and wash-down unit have a special coating on pipes and coils on the ambient side of the unit to provide maximum protection from saltwater, sour gas, and other corrosive substances.
• High Airflow Backward Curve Impeller Fan. Provides high airflow in a long lasting, single bearing design. Outperforms typical two-bearing blowers with nearly twice the lifespan.
• Self Protected from Harsh Environments. Our unit is uniquely designed to protect itself in NEMA 3R, 4, and 4X environments. An example of this is the location of our control electronics within our dry, cool interior circuit.
• 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.
• Environmentally Friendly. Utilizes HFC-free R134a refrigerant versus a blended refrigerant for easier service and minimized negative impact to the environment.
• Maintenance Free Filterless Design. The wide fin spacing is less susceptible to clogging from dirt buildup which can cause the unit to work harder and hamper efficiency.
• Active Condensate Management. Condensation is a natural by-product of refrigeration. The heated condensate collection pan boils this off thereby eliminating the need for drain tubes and buckets. To conserve power, this heater only activates when necessary.
• Lifting Lug Ports. Threaded holes accommodate the installation of lifting lugs to facilitate safe installation.
• High Ambient Performance. The DTS 3000 Series Cooling unit were designed utilizing high temperature compressors and larger condensers. Both the indoor NEMA Type 12 unit and outdoor unit perform very well in environments that require cooling where the maximum ambient temperature is 131° F.
• Rugged Design. Powder coated steel or stainless steel cover designed for manufacturing environments. Easily painted to match enclosure or machine.
