Why Choose the Pfannenberg DTS 3181 13385436158 Cooling Unit?

The Pfannenberg DTS 3181 13385436158 is a robust UL-listed industrial enclosure cooling unit designed for closed-loop thermal management of electrical cabinets, control panels and automation systems. Part of the proven Pfannenberg DTS series, it removes heat generated by sensitive electrical and electronic equipment while keeping the conditioned enclosure air separated from the surrounding environment.

This DTS 3181 variant is designed for a 460 V AC, 60 Hz supply and features a stainless-steel housing for demanding industrial installations. Its closed-loop refrigeration system helps maintain suitable cabinet temperatures without continuously introducing ambient air, making it particularly valuable where dust, moisture, oil mist or other environmental contaminants could affect enclosure components.

Part number 13385436158 is configured for NEMA Type 4X applications and features a corrosion-resistant stainless-steel construction. Measuring approximately 749 × 394 × 293 mm, the DTS 3181 provides a compact side-mounted cooling solution for industrial control cabinets requiring dependable environmental protection and active enclosure cooling.

Reliable Closed-Loop Cooling for Industrial Enclosures

Industrial enclosure cooling units such as the Pfannenberg DTS 3181 use a closed-loop refrigeration circuit to transfer heat from inside an electrical cabinet to the surrounding environment. The internal and external airflow circuits remain separated, helping maintain enclosure integrity while preventing ambient contaminants from being drawn directly across sensitive electrical components.

The stainless-steel NEMA Type 4X configuration makes this DTS 3181 particularly suitable for demanding industrial environments where corrosion resistance and enclosure protection are important. Active cooling helps maintain controlled operating temperatures around PLCs, variable frequency drives, power supplies and other heat-generating equipment, supporting equipment reliability and service life.

Typical Applications

• Industrial electrical control cabinets.
• PLC and automation control enclosures.
• Variable frequency drive and motor control cabinets.
• Power electronics and electrical distribution enclosures.
• Food, beverage and process industry equipment.
• Manufacturing and production machinery.
• Corrosive or washdown-prone industrial environments.
• Electrical enclosures requiring NEMA Type 4X closed-loop cooling.
