Product Description

Water Source Heat Pump unit is a central Air Conditioning system. When the temperature of the water in the water cycle exceed a certain value because of the cooling or heating, normally use the cooling tower to exhaust the heat from the water inside the water cycle. When the temperature in the water cycle is lower than a certain value, normally use heating equipment to supplement heat into the cycle water. When the water temperature inside the water cycle is keep in a certain range, no need the cooling tower and heating equipment, the energy saving affection is obvious.

Why this choice?
● Saving space
● Galvanised steel construction
● AMWCP are well insulated to minimise condensation and attenuate noise.

Application areas
● Offices, Hotels, Hospitals
● Administration
● Industry
●Commercial buildings


01. Structure. Galvanised steel construction, closed cell foam lined compressor and fan compartments, with an insulted and powder coated drain tray for complete moisture protection, the drain tray is easily removed for inspection and cleaning.

02. Refrigerant. Each unit is factory charged with refrigerant R410a, which is deemed to have zero ozone depletion potential.

03. Hermetic compressor. Single phas rotary compressor is used for this type unit, with built-in thermal overload cut-out, mounted on rubber vibratrion damperss.
04. Centrifugal Fan. High efficiency, double inlet centrifugal fan protection level IP44. Low noise, low speed, big air flow and high ESP.
05. Water side heat exchanger. high efficiency coaxial heat exchanger, factory insulated with flexible close cell material.
06. Air Filter. An optional filter integrated return air spigot is available on all models.The filter is a washable polypropylene netmedia. Care should be taken, when locating each unit, that to enough space is provided to enable the one-piece filter to be withdrawn to its full length from either side of the unit.
07. Insulation. AMTKWP are well insulated to minimise condensation and attenuate noise.

08. Electric Heater(Optional). Electric heater is optional on cooling only versions. Electric elements have spirally wound stainless steel fins to give increased area and low surface temperature. They are totally enclosed within the unit and are supplied with safety cutouts. An optional fan run-on timer for rapid heat dissipation is available.
09. Electric Panel
Consists of:
Compressor contactor
Compressor protection breaker
Microprocessor with function display
10. All Models are Equipped with Wire Controller with the Following Features
7 days programmable timer
Auto random restart
Error self diagnostic
11. Safety Protection
High pressure switch
Low pressure switch
Discharge temperature protection
Anti freezing protection
