PHC Evaporative Condenser

The Parallel Hybrid Condenser line of condensers has always reflected EVAPCO’s commitment to product development. Its advanced design and owner-oriented features provide many operational and performance advantages.

The PHC’s incorporates EVAPCO's Thermal-Pak II® Coil or Patented Sensi-Coil® both featuring CrossCool™ Internal Tube Enhancement which increases the internal heat transfer coefficient of the coil and thus increases the cooling capacity of the unit.

  • Great for large industrial refrigeration projects
  • The Parallel Hybrid Condenser offers great flexibility of layout and system design for a variety of situations
  • Ranging in capacity from 285 to 2,809 nominal tons
  • IBC Compliant – Independently certified by the International Building Code to withstand seismic and wind load forces in North America
  • Available with FM Approved Construction


Hot gas discharged from the compressor enters the condenser coil inlets at the top of the unit. Cooled water from the unit basin is pumped through spray distribution nozzles and floods over the condenser coils. Ambient air is simultaneously drawn into the unit at the top in parallel flow with the water through the coil. A portion of the recirculated water evaporates into the air stream, removing heat from the refrigerant and causing it to condense.

The cooled refrigerant liquid drains out of the sloped coil tubes into a pressurized receiver for return to the system. The recirculated water that did not evaporate falls through a crossflow fill section located below the coil. Air is drawn through the side of the unit and fill section, removing additional heat from the water through further evaporation. The cooled water collects in the basin for recirculation over the coil.

The hot, saturated air from both the coil and fill sections passes through internal drift eliminators to strip water droplets entrained in the air stream, reducing water consumption. The unit fan(s) then discharge the saturated air out of the top of the unit at a high velocity, where it dissipates into the atmosphere.

Thermal-Pak II Coil

EVAPCO's Thermal-Pak II coils feature a patented design which assures maximum cooling capacity. The airflow through the coil is counterflow to the fluid flow, providing the most efficient heat transfer process. A special coil design is utilized to reduce the air pressure drop through the unit while maximizing tube surface area and increasing its heat transfer capabilities.

  • Elliptical return bends allows for more circuits per coil bundle increasing the maximum capacity per footprint
  • Coil located in airstream increasing dry bulb switchover temperature
  • CrossCool Internal Tube Enhancement increase fluid turbulence providing additional evaporative capacity
  • Available in type 304 SS or type 316 SS construction
