Features
Reliability
• Standard cabinets are 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.
• Split units are equipped with hermetic scroll type compressor, compressors are provided with an internal overload protection, and incorporate crankcase heater for smooth start-up under any conditions. Famous brand compressor: Copeland and Panasonic, more reliable.
• Coils are manufactured from seamless copper tubes mechanically expanded into hydrophilic aluminum fins, the generously sized coils provide ample capacity under all operating conditions.
• Outdoor fan is multi-blade vane-axial type, made of aluminum alloy for quiet operation & durability. It is directly driven by waterproof motor to ensure reliable continuous operations.
• 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/Siemens/ABB brand.
• Sendo split units are tested at the factory to make sure no welding leakage and provide reliable start up at job site.
Quiet operation
• Compressors and low noise Supply Fan are mounted on rubber vibration dampers to reduce noise.
• Wave type acoustic Insulation for compressor section, the inside of indoor unit panels will be covered with 10mm insulation to prevent heat and noise coming out.
Easy installation and maintenance
• The units are completely assembled, internally wired, charged outdoor unit with refrigerant at the factory. The site work only needs to connect refrigerant pipes and communication wires between outdoor & indoor unit.
• Quick release fasteners provide convenient access to system components for maintenance.
Control system
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 temperatures. It will keep accurate temperature control, minimum drift from the set point and provide better comfort.
