NVENT HOFFMAN PWS7062R5 Air/ water heat exchanger

Why Choose the nVent HOFFMAN PWS7062R5 Air/Water Heat Exchanger?

The nVent HOFFMAN PWS7062R5 is a compact air/water heat exchanger designed for vertical installation on electrical enclosures where reliable cooling is required in dusty or high-temperature industrial environments. As part of the nVent HOFFMAN PWS thermal management range, it uses chilled water to remove heat from the enclosure while keeping the internal air circuit separated from the surrounding environment.

The PWS7062R5 provides a cooling capacity of 600 W at W10/A35 conditions with a water flow of 200 l/h. Its closed-loop air circuit helps ensure that ambient dust and contamination do not directly affect the enclosure interior, while IP55 protection towards the electrical enclosure helps maintain environmental integrity.

With dimensions of 500 mm high × 200 mm wide × 100 mm deep, a 230 V AC 50/60 Hz supply and an unimpeded airflow of 440 m³/h, the PWS7062R5 provides an effective cooling solution for compact industrial control cabinets. An integrated thermostat, solenoid valve and alarm contact support automatic temperature regulation and monitoring.

Key Advantages

• Efficient 600 W air/water cooling capacity at W10/A35 conditions.
• Closed-loop cooling helps isolate sensitive enclosure equipment from dusty ambient air.

Reliable Closed-Loop Cooling for Industrial Enclosures

Air/water heat exchangers remove heat from an electrical enclosure by transferring it from the internal air circuit to a separate water circuit. Because the enclosure air remains isolated from the surrounding environment, ambient dust and contamination have minimal influence on the cooling process, making this technology particularly useful for demanding industrial locations.

The nVent HOFFMAN PWS Series is designed for applications where effective cooling is required without introducing external air into the enclosure. The PWS7062R5 combines compact dimensions with integrated temperature control, monitoring and water regulation, making it suitable for protecting PLCs, drives, power electronics and other heat-generating equipment.

Typical Applications

• Industrial electrical control cabinets.
• PLC and automation enclosures.
• Variable speed drive and power electronics cabinets.
• Machine control systems in dusty environments.
• Manufacturing and process automation equipment.
• Electrical enclosures exposed to elevated ambient temperatures.
• Applications with an available chilled-water supply.
