The refrigerant gas is discharged from the compressor into the inlet connection of the evaporative condenser. Water from the condenser’s sump is continuously flooded over the condenser coil, while ambient air is simultaneously forced into the unit. As the ambient air moves up through the coil section, a portion of the spray water is evaporated into the air stream.
The evaporative process cools the spray water, which in turn cools the tubes containing the refrigerant gas. The cool tube walls cause the refrigerant gas to give up heat and condense into a liquid. The condensed liquid flows out of the coil’s sloping tubes to the high pressure liquid receiver for return to the system.
The hot, saturated air is driven through the drift eliminators, where any entrained water droplets are removed. The hot saturated air discharges out of the top of the unit at a high velocity, where it can dissipate harmlessly into the atmosphere. The water which was not evaporated falls into the sump and is recirculated by the spray pump to the water distribution system above the condensing coil section.
Dry Mode
The refrigerant gas is discharged from the compressor into the inlet connection of the condenser. Cool ambient air is forced into the unit and moves over the heat transfer coil. The air is warmed as the cool tube walls cause the refrigerant gas to give up heat and condense into a liquid. The condensed liquid flows out of the coil into a high pressure receiver for return to the system. The hot discharge air continues through the drift eliminators and where it can dissipate harmlessly into the atmosphere.
DESIGN FEATURES
Reduced Plan Area
Due to the increased thermal performance, KEG condensers can be selected specifically to minimize the unit plan area while maximizing capacity for those applications where space is limited.
Significant Water Savings
KEG evaporative can operating in a 100% dry mode at a significantly higher dry bulb switchover temperature than that of a typical bare tube coil evaporative condenser and even higher when compared to hybrid condensers utilizing a combination of reduced coil surface and PVC cooling tower fill material. This leads to a significant increase in the number of hours per year the condenser can operate in dry mode (spray pumps off), thus increasing your water savings. This combination of features allows KEG evaporative to be operated with both water and energy efficiency in mind, making it the ideal choice for most geographic locations.
Winter Non-Freezing Design

The unique blast design makes the KEG series evaporative cooling have a better anti-freezing effect. It can better meet the operation of low temperature in winter. Its blast working mode can make the evaporative cooling non-freezing in low temperature environment. The advantage of this is not only saving energy but also saving water.

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.
