PMRC

The redesigned PMRC product line utilizes single-stage axial fan configuration at ground level with more redundancy, increased reliability, and easy maintenance access. The PMRC features Thermal-Pak II® Coil with CrossCool™ Internal Tube Enhancement for increased internal heat transfer coefficient of the coil and thus increased the cooling capacity of the unit. The PMRC offers the most models and box sizes in the industry and is designed with IBC Compliant Construction.

  • CrossCool enhanced for greater heat exchange
  • 50% reduction in energy consumption compared to traditional centrifugal fan condenser models
  • Ranging in capacity from 124 to 1,516 nominal tons
  • IBC Compliant – Independently certified by the International Building Code to withstand seismic and wind load forces in North America

The refrigerant gas discharges from the compressor into the inlet connection of the PMRC condenser. Heat from the refrigerant dissipates through the coil tubes to the water cascading downward over the tubes. Simultaneously, air is forced in through the single-stage axial fans at the base of the condenser and travels upward through the coils, opposite the water flow. A small portion of the water evaporates, removing heat from the system; the saturated hot air is discharged to the atmosphere. The remaining water falls to the sump at the bottom of the condenser where it is recirculated by the pump up through the water distribution system and back down over the coils.

Thermal-Pak II Coil

EVAPCO's patented Thermal-Pak II coils 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 ambient 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
Drift Eliminators
  • Limits the drift rate to less than 0.001% of the recirculating water rate
  • Reduces water loss during wet operation
  • Constructed of an inert polyvinyl chloride (PVC)
Pressurized Water Distribution System

EVAPCO's Zero Maintenance ZMII® spray nozzle remains clog free while providing even and constant water distribution, providing the industry's best performing non-corrosive, maintenance-free water distribution system.
