Reliable Thermal Management for Outdoor Electrical Enclosures
Enclosure cooling units such as the Pfannenberg DTS 3261 remove heat generated by drives, PLCs, power supplies and other electrical components while maintaining separation between the conditioned cabinet air and the surrounding environment. Closed-loop cooling helps maintain stable internal temperatures while reducing exposure of sensitive equipment to dust, moisture and contaminated ambient air.
The DTS 3261 is particularly suited to demanding industrial and outdoor installations. Its NEMA 3R/4 protection, robust powder-coated steel construction, wide condenser fin spacing and integrated condensate evaporation provide dependable thermal management, while the Low Ambient Package adds a 900 W heater and thermostat for applications exposed to low ambient temperatures.
Typical Applications
- Outdoor electrical and automation control cabinets.
- Industrial machinery and production equipment.
- PLC, drive and motor control enclosures.
- Process automation and control systems.
- Material handling and conveyor equipment.
- Electrical cabinets exposed to contaminated ambient air.
- Industrial installations requiring NEMA 3R/4 enclosure protection.
- OEM machinery and outdoor automation systems.
