2. 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. This has the added advantage of lowering start-up current.

- Durable construction
 Standard cabinets are constructed from high grade galvanized steel with polyester powder coated, they are completely weatherized for outdoor installation.
 Coils are manufactured from seamless copper tubes mechanically expanded into hydrophilic aluminum fins, they are tested under 450 Psi at the factory to avoid leakage. They also undergo dry chemical cleaning after manufacturing for optimum system cleanness.
 External fasteners are stainless steel or galvanized type. Corrosion resistant drain trays are also included.
 All units are tested at the factory to make sure no leakage and provide reliable start up.

- Reliable scroll compressor
High efficiency scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater. 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.
• Main power supply breaker is optional.
 All electric parts are Schneider Electric brand.

3. Quieter operation

 Compressors and low noise Supply fan are mounted on rubber vibration dampers.
 Wave type acoustic Insulation for compressor section, thermal insulation for coil and fan section.

4. Easy installation & maintenance

 All units are factory assembled, internally wired, fully charged refrigerant.
 The Rooftops has provisions for forklift and 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.

5. Control system

 The unit is completely factory-wired with necessary controls and terminal block for power wiring.
 Syslab wired controller is supplied with unit controls as standard. The precision control makes all heating, cooling, or ventilating decisions in response to electronic signals from sensors measuring indoor and outdoor temperatures.
 Besides standard Syslab wired controller, Siemens & Carel PLC controller with BMS function and precision temperature & humidity control can be matched as optional solution.
