cATC Evaporative Condenser

The containerized Advanced Technology evaporative condenser provides an induced-draft, axial fan solution for a wide array of outdoor cooling capacities, and is optimally designed to fit inside a shipping container to reduce ocean freight costs. Bringing EVAPCO's Advanced Technology design to closed circuit coolers, the cATC features the Thermal-Pak II® Coil with CrossCool™ Internal Tube Enhancement, offering incredible evaporative cooling capacity using its advanced counterflow design.

  • Containerized: designed to fit completely inside 20 and 40 foot shipping containers, reducing costs
  • Available in a huge range of models and box sizes unparalleled in the industry
  • Ranging in capacity from 128 to 357 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 cATC condenser. Heat from the refrigerant dissipates through the coil tubes to the water cascading downward over the tubes. Simultaneously, air is drawn in through the air inlet louvers at the base of the condenser and travels upward over the coil opposite the water flow. A small portion of the water evaporates, removing heat from the system. The warm moist air is drawn to the top of the evaporative condenser by the fan and discharged to the atmosphere. The remaining water falls to the sump at the bottom of the condenser where it recirculates 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 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
