2. Outstanding reliability
Durable construction
The casing is made of zinc coated galvanised steel sheets. It is further treated with an electrostatic powder coat then over baked to provide a weather resistant finish to suit the harsh climate. The screws are also zinc plated to improved product durability.
Reliable scroll compressor
High efficiency scroll type compressor is hermetically sealed, quiet running and supported on rubber mounts to minimise vibration.
All compressors are provided with an internal overload protection, and incorporate crankcase heater for smooth start-up under any conditions. Famous brand compressor: Panasonic, Copeland and Danfoss. More reliable.
Heat-exchanger coils
Heat-exchanger coils
The condenser and evaporator coils are manufactured from seamless copper tubes mechanically bonded to blue hydrophilic aluminium fins to ensure optimum heat transfer. The generously sized coils provide ample capacity under all operating conditions.
Outdoor and Indoor fan
• The outdoor fan is multi-blade vane-axial type, made of aluminum alloy for quiet operation and durability. It is directly driven by waterproof motor to ensure reliable continuous operations.
• The indoor fan is centrifugal type. The fan is directly driven (Model 20~100) & belt driven (Model 120~180) by waterproof motor. The fan and motor assembly is tested and dynamic balance is implemented in the factory.
Multi-protection design
• Electric panel consists of breakers and contactors for compressors & fan motors, phase sequence relay and other necessary protection devices to ensure units operate normally and reliably.
• All electric parts are Schneider Electric brand.
3. Easy operation line controller
• Cooling/Heating/Fan/Auto
• Error indication
• Timing on/off
Units are completely factory-wired with necessary controls and wiring terminals for power wiring. Microprocessor controls the cooling,heating and ventilating modes in response to signals from sensors measuring indoor and outdoor temperature. It will keep accurate temperature control, minimum drift from the set point and provide better building comfort.
