Air Cooled Chiller

The Air Cooled Chiller LEACC supplies chilled process water to ovens, test chambers, reactors and other laboratory and process equipment. The unit absorbs heat from the circulating water and rejects it to the surrounding air, so no cooling tower or condenser water pump is required. It suits installations where the discharged heat is not a concern; in winter the warm air can be used to heat the plant.

How it works

Return water enters a stainless steel tank, is cooled in a coil-type evaporator by the refrigerant circuit, and is delivered to the process by a centrifugal pump. Sealed scroll-type compressors circulate the refrigerant, which is condensed in a V-shaped finned air condenser. A microcomputer temperature controller with an LED touch screen holds the water at a set point between +5 and +35 °C to ±1.0 °C. Compared with water cooled units, air cooled chillers need less maintenance but draw about 10 percent more power.

The reference model LEACC-15 gives 35 kW (30380 kcal/h) of cooling at 10 °C inlet and 7 °C outlet water, from a 3N 380 V 50 Hz supply at 26 A total current. It has three compressors of 3.75 kW each, a pump of 22 m head and 180 L/min flow, a 250 L 304 stainless steel tank, DN50 water inlet and outlet (customized on request), refrigerant R407C, and an external size of 1660 x 880 x 1650 mm. Stationary, portable and central configurations are offered.

Air Cooled Chillers Vs Water Cooled Chillers

• Air cooled chillers require less maintenance than water-cooled units.
• Air cooled chillers do not require a cooling tower or a condenser water pump.
• Consume approximately 10% more power than a water-cooled unit due to wet surfaces transferring heat better than dry surfaces.
