components to achieve its low noise level.

Free of Cooling Tower
Heat dissipation in the way of air cycleeliminates the need for cooling water tower. Thus, not only does it save the cost and space for cooling tower it also eliminates water shortage concerns.

Space Saving
As 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 a plant room.

EasyInstallation
Each chiller is charged with full factory refrigerant and oil charge further reduces field labor, materials, and installation cost. All units are factory run tested. Only power supply and water piping are required to be connected on the jobsite.

Available Options
Either 220V or 380V is available for the mini-type and either 380V or 415V is available for some models of the standard type. Inaddition, pressurized water tank and blue fin are available to meet various requirements.

In addition, the preset low temperature protection command can start the machine automatically to protect the water pipes from freezing.

LCD Microprocessor-based Housing
All parts are fabricated to precision by state-of-the-art CNCmachines. 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 vibration.

Adjustable Water Temperature Control
Precise temperature control of inlet chilled water, operation modes andsystem 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 available.

Compressor
