The PKS3131A230LG is a Type 12 air-to-air heat exchanger for indoor enclosures, rated 65 W/°C (36 W/°F) and powered from 230V 50/60 Hz. Its capacity is the entry capacity of the PKS12 range (65, 100, 150 and 180 W/°C). It suits panel builders and facilities engineers cooling control enclosures where the surrounding air is cooler than the target internal temperature by at least 10°C/18°F.
Closed loop cooling recirculates clean enclosure air without ever mixing it with contaminated ambient air. At a ΔT of 20°C/36°F between ambient and target internal temperature, sample performance is 1300W (4400 BTU); actual performance depends on that difference. The manufacturer cites superior energy efficiency and lower maintenance costs versus air conditioners.
The unit measures 35.31 in (897 mm) high, 11.97 in (304 mm) wide and 10.65 in (271 mm) deep (nominal 35 x 12 x 11 in), and ships at 62 lbs (28.12 kg). The cover is Light Gray (RAL7035) powder coated steel. It can be mounted vertically or horizontally, and the gasket, mounting kit and template for cutout and drilling are included.
The PKS3131A230LG maintains the enclosure's NEMA 12 rating, is IP 54, and carries UR, cUR and CE marks, with EMI/RFI suppression that meets CE. The thermostat control is accessible from inside the enclosure, and a door contact provision powers the unit down when the enclosure door is opened. It is REACH and RoHS compliant.
Ideal For
- Indoor NEMA 12 control enclosures in cooler ambient conditions
- Closed loop cooling where ambient air is contaminated
