Evapco MOD.ATC-642E

The refrigerant gas exits the compressor and flows to the air inlet connection of the ATC-E condenser. Heat from the refrigerant is transferred through the heat exchanger tubes to the water that flows downward through the tubes. Simultaneously, air is drawn into the air inlet grilles at the base of the condenser and flows upward over the heat exchanger, counter to the water flow. A small portion of the water evaporates, and heat is removed from the system. The warm, moist air is drawn by the fan to the top of the evaporative condenser and released into the atmosphere. The remaining water falls into the collection basin at the bottom of the condenser, where it is recirculated through the water distribution system and flows down over the heat exchanger.

Thermal-Pak II Heat Exchanger
EVAPCO's Thermal-Pak II heat exchangers, featuring a patented design, ensure maximum cooling capacity. The airflow through the heat exchanger is countercurrent to the fluid flow, resulting in the most efficient heat transfer process. A specially designed heat exchanger is used to reduce air pressure drop across the unit while maximizing the tube surface area and increasing the heat transfer capacity.

Elliptical return bends provide more circuits per heat exchanger bundle and increase the maximum capacity per footprint.
The heat exchanger is located in the airflow, resulting in an increase in the dry-bulb temperature.
CrossCool internal tube enhancement increases fluid turbulence and provides additional evaporative capacity.
Available in type 304 SS or type 316 SS construction.
Drift eliminators
Limit drift rate to no more than 0.001% of the recirculated water flow rate.
Minimize the risk of Legionella spread.
Constructed with an inert polyvinyl chloride (PVC).
Superior air inlet louvers and screen design.
Constructed with an inert polyvinyl chloride (PVC).
Two-tier design that minimizes drift loss and the potential for algae growth in the tower.
Framed in steel in easily removable sections.
Pressurized water distribution system
EVAPCO's zero-maintenance ZMII® spray nozzle remains clog-free, allowing for even and consistent water distribution. This makes it the best-performing, corrosion-resistant, and maintenance-free water distribution system in the industry.

ZMII spray nozzles have a 1-1/4" diameter opening and a 1-1/4" transparent splash plate.
Mounted in corrosion-resistant PVC water distribution piping with threaded end caps.
Provides unparalleled heat exchanger coverage and scale prevention.
