Air-Cooled Screw Chiller
  Product details

Screw Chiller Applications:
For cooling moulds to reduce products molding cycle,also they are available in the cooling of equipments in order to maintain normal temperature.Besides,they are suitable for other industries with the need of cooling.
In large industrial cooling
Central air conditioning system
Cold, constant temperature chamber.
Well Known Brand Compressor
Unit adopts Taiwan HANBELL  or  Germany BITZER brand semi-hermetic screw compressor. The latest 5 to 6 patented screw rotor profile with excellent efficiency.
Adjustable infinite or closely stepped capacity control, features energy efficient, stable and quiet running.
Built-in full intelligent monitoring and protection including thermal motor temperature monitoring, phase sequence monitoring, manual reset lock-out ,oil temperature sensor.
Wide range of refrigerant for option, including R22 and R134a,R407c.

Microprocessor Control System
Industrial PLC centralized control combined with compressor capacity control system,precisely monitor, ensure the unit is running at optimum efficiency and reduce operating costs.

Integrated water, low temperature, high/low pressure, antifreeze, missing phrase  , delay start,  anti-phase, overload, motor overheating,oil pressure differential  and so on many safety protections and dealing.
W shape aluminum fin type condenser,assuring adequate heat exchanging area within smaller unit size
High efficient evaporator with internal thread copper tube.
Large air volume axial fan with metal blades.Motor separated from net-cover,fixed on exhaust port by metal.

Easy Installation, Reliable Running
Closely stepped start-up, minimize impact to electricity.
Steady and safe running, low vibration, easy for installation.
Compact structure, less space demand and light in weight, easy for transport and installation.
Completely wired, inspected and tested pre-delivery, saving installation time and cost.

Working Principe:
Cooling circulation: the high temperature .high pressure air from compressor¡¯s high pressure spraying outlet comes into fin type air side heat exchanger, which works as a condenser to cool down the air into liquid .Then it comes into expansion valve after filtration. There,after a pressure downfall, it comes into shell and tube type evaporator. The low temp.low pressure and saturated refrigerant absorbs the heat from cooling water so to low down its temperature. The state of the shell and tube type evaporator¡¯s refrigerant outlet are low temperature low pressure air then comes to air and liquid separator to be separated. Therefore, the air comes to compressor¡¯s low pressure air suction inlet to get compressed. The high pressure spraying outlet(compressor)¡úcondenser(air side heat exchanger)¡úfilter expansion valve  ¡úevaporator(water side heat exchanger)¡úair and liquid separator¡úthe low pressure air suction inlet.

Combination of modules unit as shown in the figure.
