AIR TO WATER HOT WATER HEAT PUMP UNITS

Evaporator:
The evaporator is cut In waffle fins, in a louver shape so as to increase heat transfer co-efficiently. Furthermore, Hi-X internal screw thread tubes, of which the internal surface has been modified by serration, are used for additional efficiency.

Heat Exchanger:
The heat exchanger on the water side is of coaxial type, made from seamless carbon steel tube for outer tube and twisted copper tube for inner tube. Comparing to other smooth tube-in-tube heat exchangers, the configuration of a spiral twisted tube creates a two-counter-directionai flowing pattern, with a hot and cold side, ensuring the highest heat transferring efficiency. Its other advantages include its compactable size, adaptability, durability and leakage protection.

Heat pump coaxial coils
Condenser:

Compressor:
The scroll compressor used within the heat pumps is compact, light, highly efficient, powerful and durable. The compressor is held by springs in its casing to minimize vibration, while special vibration isolation rubber pads reduce vibration transfer to a minimum. A complete set of safety devices such as over-current relay, compressor thermal protector encased in the motor coil, high pressure switch, and crankcase heater are equipped, ensuring a longer life-cycle and problem-free operation.

Operation can easily be controlled from indoors by means of the remote controller, a slim, compact design that operates on a 24V safety circuit.

Safe operating and easy maintenance:
A complete set of safety devices, fitted on the front of the unit, protects the unit from potential problems:

New refrigerant circuit:
A large supply of hot water of up to 60
