Matched with a large variety of fan coils of different sizes it can be widely used in top grade apartments, luxury villas, offi ce buildings, small-sized restaurants, retail stores and hotels to create a comfortable and delightful indoor appearanceKoolman boasts of its state-of-the-art appearance.

2 The contemporary appearance, designed by expert designers, will be naturally integrated with the surrounding environment and will defi nitely display your prominent footprintAs a result of the particular slim design (standard type is 500mm thick while mini type is only 393mm thick), the unit can be installed directly on the veranda, rooftop or ground without the need to have aplant optionsUnit with pressurized water tank is available to meet various levelKoolman uses low noise fans and components to achieve its low noise installationEach chiller has factory charged oil and refrigerant for reducing fi eld labor and materials costs. All units are factory run tested. Only power supply and water piping are required to be connected on the friendly refrigerantAll models are charged with R410A of Cooling TowerHeat dissipation in the way of air cycle eliminates the need for cooling water tower.

3 Thus, not only does it save the cost and space for cooling tower it also eliminates water shortage Specifi cationsGeneralKoolman air-cooled liquid chiller is designed to couple with fan coil units and air handling units for residential and light commercial air conditioning applications. Units are composed of scroll compressor (s), plate type evaporator, fi nned-coppertube and aluminum condenser, axial fan assembly, expansion valve, four-way reversal valve (heat pump only), indoor Cooling/Heating control switch, water fl ow switch, fi lter dryer, sight-glass, built-in water pump, galvanized sheet metal housing with powder paint and factory mounted controls. Optional fi ttings include pressurized water tank on capacity range, units come with single or double scroll compressors to cater for changing demand and effi cient part load is a compact brazed plate heat exchanger with AISI 316 stainless plates and adapters.

4 A 20-mesh strainer is installed at the water inlet to protect the evaporator and unit against fouling. The strainer (factory provided, fi eld installed) can be removed for parts are fabricated to precision by state-of-the-art CNC machines. The frame design allows all panels to be removed for service without affecting the structure of the unit. The panels are made of galvanized steel plate with powder paint. All panels are internally insulated with single layer foam cell in order to reduce noise and pumpPump is Rotodynamic pumps and adopts a mechanical shaft seal. Motor is fan cooled (TEFC), 2-pole induction type. Pump is installed in the unit to save installation space and also to reduce noise and protection devicesThe controller contains all the basic electrical protection devices including electromagnetic switches, relays and current overload protectors.

5 The automatic control devices consist of high and low pressure switches, thermostatic and anti-freeze cutouts, which improve and protect the unit's normal addition, the preset low temperature protection command can start the machine automatically to protect the water pipes from microprocessor-based controllerPrecise temperature control of inlet chilled water, operation modes and system protection are provided by the long-range controller. In addition, the password can be set and any abnormal condition will be monitored and captured to facilitate quick repair and normal operation. In addition, the interlocking function of the two-way valve is condenserThe unit comes with air-cooled fi n-tube U or V shaped condensers. Copper tubes are of the 3/8" diameter, seamless type. Fins are aluminum with effi cient Wavy fi n. Copper tubes are expanded mechanically to bond with the fi ns for effective heat transfer.
