Pfannenberg Cooling Unit UL listed DTS 3161 230V SC N3R 7035 LADTS 3161 230V SC N3R 7035

Why Choose the Pfannenberg DTS 3161 230V LAP Cooling Unit?

The Pfannenberg DTS 3161 230V LAP, article number 13385441375, is a robust side-mounted enclosure cooling unit designed to maintain reliable operating temperatures inside electrical and industrial control cabinets. As part of the Pfannenberg DTS 31X1 outdoor cooling unit series, it combines high cooling performance with a compact, rugged construction suitable for demanding industrial and outdoor applications.

This UL listed cooling unit provides 1235 W cooling capacity at A35/A35 and incorporates an integrated condensate evaporation system for dependable condensate management. Its large condenser fin spacing helps provide effective protection in contaminated ambient air while supporting extended maintenance intervals. The powder-coated steel cover and NEMA protection make the DTS 3161 particularly suitable for industrial control panels exposed to challenging environmental conditions.

The 13385441375 is the 230 V AC LAP (Low Ambient Package) version of the DTS 3161. The LAP configuration extends the operating ambient temperature range down to −40 °C and includes a 900 W enclosure heater with a thermostat for installation inside the enclosure, making it well suited to outdoor control cabinets and installations exposed to very low temperatures.

Reliable Cooling for Industrial Electrical Enclosures

Industrial enclosure cooling units remove excess heat generated by drives, power supplies, PLCs and other electrical components while maintaining separation between the enclosure air and the surrounding environment. Maintaining a controlled internal temperature helps reduce thermal stress on sensitive equipment and supports reliable operation of automation and control systems.

The Pfannenberg DTS 3161 is designed for external side mounting and combines a rugged construction with efficient enclosure cooling. The Low Ambient Package fitted to article 13385441375 makes this version particularly valuable for outdoor installations, where electrical cabinets can experience both high internal heat loads and extremely low seasonal ambient temperatures.

Typical Applications

• Outdoor electrical and automation control cabinets.
• Industrial machinery and production equipment.
• PLC, drive and motor control enclosures.
• Process automation systems.
• Manufacturing and material handling equipment.
• Electrical cabinets exposed to low ambient temperatures.
• Industrial installations requiring NEMA-rated enclosure protection.
• OEM machinery and automation systems.
