Why Choose the Pfannenberg DTS 3265 230V HT SC 7035 Cooling Unit?

The Pfannenberg DTS 3265 230V HT SC 7035, article number 13393841001, is a powerful high-temperature side-mounted enclosure cooling unit designed for dependable closed-loop climate control of electrical and industrial control cabinets. As part of the Pfannenberg DTS high-temperature cooling unit series, it is engineered for demanding industrial and outdoor applications where reliable cooling is required at ambient temperatures of up to +60 °C.

This UL listed cooling unit combines high cooling performance with a robust galvanised sheet steel construction and electrostatically powder-coated RAL 7035 light grey finish. Its NEMA Type 3R/4 enclosure-side protection and IP56 protection classification make it suitable for challenging environments, while the closed-loop refrigeration system helps isolate sensitive electrical equipment from contaminated external air.

With a rated cooling capacity of 3040 W at A35/A35 and 1405 W at A40/A60, the DTS 3265 HT provides substantial cooling performance even under elevated ambient temperature conditions. The unit operates from a 230 V AC, 50/60 Hz supply and incorporates a standard controller, integrated condensate evaporation and a condenser with wide fin spacing for reliable industrial operation.

Reliable High-Temperature Cooling for Industrial Enclosures

Enclosure cooling units such as the Pfannenberg DTS 3265 HT remove excess heat generated by drives, PLCs, power supplies and other electrical components while maintaining separation between conditioned cabinet air and the surrounding environment. This closed-loop cooling principle helps protect sensitive equipment from dust, moisture and contaminated ambient air while maintaining suitable internal operating temperatures.

The DTS 3265 HT is specifically engineered for applications exposed to extreme ambient heat. Its ability to operate at temperatures up to +60 °C, combined with NEMA Type 3R/4 enclosure-side protection, IP56 protection, wide condenser fin spacing and integrated condensate evaporation, makes it a dependable thermal management solution for demanding industrial and outdoor control applications.

Typical Applications

• Outdoor electrical and automation control cabinets.
• Industrial installations exposed to high ambient temperatures.
• PLC and process control enclosures.
• Variable frequency drive and motor control cabinets.
• Manufacturing and production machinery.
• Material handling and conveyor systems.
• Electrical cabinets operating in contaminated industrial environments.
• OEM machinery and industrial automation systems.
