The original Advanced Technology evaporative condenser provides an induced-draft, axial fan solution for a wide array of cooling applications. The ATC-E'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.

  • Available in a huge range of models and box sizes unparalleled in the industry
  • Ranging in capacity from 50 to 3,714 nominal tons
  • IBC Compliant – Independently certified by the International Building Code to withstand seismic and wind load forces in North America
  • 7’ wide single and multi-cell box sizes available for containerized, export shipments

The refrigerant gas discharges from the compressor into the inlet connection of the ATC-E 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 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)
Superior Air Inlet Louver and Screen Design
  • Constructed of an inert polyvinyl chloride (PVC)
  • Two pass design that minimizes splash-out and the potential for algae formation inside the tower
