Air to Air Heat Exchangers - Mini Type 4X PKSMINI Series


  • Designed for indoor, outdoor, corrosive outdoor or washdown applications.
  • Air to air heat exchangers provide superior technology when there is a lower surrounding air temperature compared to the target internal temperature (difference of at least 10°C/18°F).
  • Closed loop cooling ensures clean enclosure air is recirculated without ever mixing with contaminated ambient air.
  • Superior energy efficiency and lower maintenance costs versus air conditioners.


  • Maintains enclosure's NEMA 4X rating
  • IP 56
  • UR, cUR and CE


  • R134a refrigerant.
  • Thermostat control accessible from inside enclosure.
  • EMI/RFI suppression meets CE.
  • Door contact provision for power down when enclosure door is opened.
  • Gasket, mounting kit and template for cutout and drilling are included.
  • Can be mounted vertically or horizontally for application flexibility.
  • Cover finished in unpainted 316 stainless steel
  • See Manual/Technical Data Sheet for drilling template and full electrical specifications.
