• Coil construction materials available for CO2 evaporators
  • Can be designed for pump recirculated, DX and brine feed methods
  • All CO2 selections feature 5/8” diameter tubes in an inline arrangement


Description

Colmac A+ Series™ Air Coolers are designed to be compatible with CO2 (R744) as the refrigerant. The process for selecting a CO2 cooler is similar to that of an ammonia or freon cooler, but there are different material and pressure requirements.

Advantages

  • Coil circuiting is customized to match each application for optimal heat transfer with the appropriate tube side pressure drop
  • 5/8” diameter tubes in an inline arrangement providing the lowest air pressure drop and offers a large amount of secondary (fin) surface area for maximum frost carrying capacity and extended runtime between defrosts
  • All fins are a continuous design with a clean, full collar to optimize performance and cleanability
  • Hinged fan panels for ease of inspection, cleaning, and service
  • "Triple Pitch" V-bottom drainpan design provides for rapid and complete drainage of melted frost and ice
  • High efficiency fan blades with a true airfoil shape
  • Standard fan motors are premium efficiency, internal rotor, totally enclosed and VFD compatible
  • Cradle crate safely supports the weight of the air cooler while it is lifted into position from below
  • Distribution pans are designed to be easily removable for inspection and cleaning while the air cooler remains in place and undisturbed

Application

  • Industrial refrigeration
