The Kaeser Combi Cooler is a high-performance, integrated heat exchanger designed specifically for the ASD, BSD, CSD, and DSD series rotary screw compressors to provide simultaneous cooling of both lubricating oil and compressed air. Featuring a robust aluminum bar-and-plate construction, this "two-in-one" unit combines an oil cooler and an aftercooler into a single, compact assembly, ensuring that the compressor remains within its optimal thermal range even during 24/7 heavy-duty operation. By precisely lowering the temperature of the Sigma Fluid before recirculation and cooling the discharge air to facilitate moisture removal, the Combi Cooler protects the high-precision Sigma Profile™ air-end from overheating and ensures downstream dryers can operate at peak efficiency. These genuine coolers are engineered for low pressure drop and high thermal conductivity, making them essential for maintaining the energy-efficient, reliable performance for which Kaeser systems are known.
