KEG Forced Draft Evaporative Condenser

Key Benefit

• 100% heat rejection guarantee:CTI Standard STD201(21) certified, capacity range 100–3000kW per single cell, suitable for container delivery.

• Lower horsepower options:Individual fan drive system with lower horsepower requirements, reducing power consumption while maintaining efficient heat rejection.

• Low sound fan:Super low sound axial fan design with direct drive, minimizing noise levels for areas with strict noise requirements.

• Flexible design:Suitable for serious water shortage areas, cold regions, limited plan area installations, and indoor installations. Can operate in both evaporative and dry modes.

• Significant water savings:Supports 100% dry mode operation at a significantly higher dry bulb switchover temperature than typical bare tube coil condensers, increasing the number of operating hours per year with spray pumps off.

• Antifreeze design:Dry mode operation in winter time prevents water from freezing, ensuring safe operation in cold regions.

Principle of Operation

Evaporative Mode

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.

Customer Review

Heat Exchange Efficiency

"The forced draft design delivers uniform airflow across the coil. We've seen a consistent 12-15% improvement in cooling efficiency compared to our old induced draft units."

Maintenance & Accessibility

"With the fan and motor located at the bottom, our maintenance team can access all moving parts without climbing onto the unit. This has cut our service time by nearly half."

Space-Saving Design

"Our plant has limited ceiling height. The low-profile forced draft design fit perfectly where other units wouldn't. We didn't have to modify our building at all."

Corrosion Resistance

"We operate in a harsh chemical environment. The stainless steel coil option was recommended based on our specific conditions. After 18 months, there's no sign of corrosion or degradation."

Service & Support

"The CASEN team conducted a thorough site survey before recommending this model. The unit arrived fully assembled, and their technicians completed installation within our tight 5-day shutdown window."
