Features
Convenient for unit selection
• Colour selection
The frame & panel can be ordered in either white or dark grey colors.
• Wide cooling capacity range
There is a large production line of packaged units, with capacities ranging from 3Ton to 110Ton (12kW to 392kW) at nominal conditions.
• Panels selection
Panels can be constructed of galvanized steel coated or Panels are double-skin with injection of high density polyurethane.
Outstanding reliability
Economy
Some models feature the flexibility and economy of 2~4 stages operation. Compressors are progressively switched on only as they are needed.
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.
• Coils are manufactured from seamless copper tubes mechanically bonded to hydrophilic aluminium fins to ensure optimum heat transfer. The shoulder of each fin adjoins the shoulder of the adjacent fin, completely encasing the copper tubes for maximum heat transfer. The generously sized coils provide ample capacity under all normal operating conditions.
• External fasteners are stainless steel or galvanized type.
• All units are tested at the factory to make sure no leakage and provide reliable start up.
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: Copeland, Panasonic and Danfoss. More reliable.
Multi-protection design
• Electric panel consists of breakers and contactors for compressors, condenser & evaporator fan motors, phase sequence relay and other necessary protection devices for the main components.
• All electric parts are Schneider Electric/Siemens/ABB brand.
Easy installation and maintenance
• All units are factory assembled, internally wired, fully charged refrigerant.
• The Rooftops has provisions for forklift or crane lifting. On arrival to the job site they are ready to be lifted to their operating position through the lifting supports available on the units. Only connect the wires of power supply, and no need to connect any signal wires.
• Quick release fasteners or removable the access doors on the compressor, fan motor, filter, and electric box sections, provide convenient access to system components for maintenance and service.
• The unit provides external pressure gauge for convenient and fast checking system pressure without removing the panel.
• If the unit is in running with abnormal operation, the controller will show the error code for easy troubleshooting.
• Standard washable filter, easy to clean.
Smart control system
• The unit is completely factory-wired with necessary controls and terminal block for power wiring.
• User friendly factory fitted LCD interface with configurable temperature sensors.
