£854.00
The nVent HOFFMAN PWS7102R5 is a compact and efficient air/water heat exchanger designed for vertical installation on electrical enclosures where dependable cooling is required in dusty or high-temperature industrial environments. As part of the nVent HOFFMAN PWS Series, it removes heat using a water circuit while keeping the enclosure air isolated from the surrounding atmosphere.
The PWS7102R5 provides a cooling capacity of 950 W at W10/A35 conditions with a water flow of 200 l/h. Its closed-loop cooling principle helps prevent dust and airborne contamination from entering the electrical enclosure, while IP55 protection towards the enclosure supports reliable operation in demanding industrial applications.
With dimensions of 500 mm high × 200 mm wide × 150 mm deep, a 230 V AC 50/60 Hz supply and an unimpeded airflow of 570 m³/h, the PWS7102R5 delivers effective thermal management in a compact format. An integrated thermostat, solenoid valve and temperature alarm contact provide automatic cooling control and system monitoring.
Air/water heat exchangers remove heat from electrical enclosures by transferring thermal energy from the internal air circuit to a separate water circuit. Because the internal enclosure air remains isolated from the surrounding environment, dust and contamination have minimal influence on the cooling process, making this technology particularly effective in harsh industrial locations.
The nVent HOFFMAN PWS Series is designed for applications where reliable cooling is required without introducing external air into the enclosure. The PWS7102R5 combines compact dimensions, 950 W cooling capacity, automatic thermostat control and water flow regulation to help protect PLCs, drives, power electronics and other heat-generating equipment.
