The LRC’s Thermal-Pak II® Coil features CrossCool™ Internal Tube Enhancement for increased internal heat transfer coefficient of the coil, and thus increases the cooling capacity of the unit.

  • The standard in low-sound, centrifugal fan, forced-draft evaporative condensers
  • Suited for indoor and ducted layouts, ideal for exact replacement projects
  • Ranging in capacity from 25 to 379 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 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 two-stage vane 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. Cooler water drains to the basin 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. The vertical air discharge of the LRC design and the distance between the discharge air and the fan intake reduce the chance of air recirculation since the warm humid air is directed up and away from the unit.

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)
