Screw Compressor 80-1000KW Air Cooled Chiller

Main Parts of Screw Air Cooled Water Chiller

1.Fin type air-cooledcondenser:Fin type air-cooled condenser adopts imported high purely, seamless screw thread copper and special aluminum fin after mechanical expanding joint closely. It ensures fin type condenser work in best efficiency Fin type air-cooled condenser adopts imported high purely, seamless screw thread copper and special aluminum fin after mechanical expanding joint closely. It ensures fin type condenser work in best efficiency;

2.Tube in tube(Shell and Tube) typeevaporator:

1) It is tube in tube(Shell and Tube) structure with new developed fire-proof and water-proof material as heat preservation. The

water-side working pressure may reach to 2.0 MPa.

2) There is PVC engineering plastic breakwater inside of evaporator with strong anti-corrosion ability. Chilling

water circuitous goes up and down to increase tumble effect, and heat exchange ability.

3) Adopt new technology DAC weave interior screw threat, high efficient heat exchange tube to ensure good

cooling characters.

3.Semi-hermetic screwcompressor:

The unit uses imported semi-hermetic screw type compressor. Comparing piston type compressor, the

semi-hermetic screw type compressor has following advantages:

1) Less accessories (Approximately 1/3 of piston compressor). The unit structure is simply and long service life).

2) The unit EER ≥3.1W/W;

3) Screw type compressor may adjust energy in range 25% - 100%.

4.Four-way valve: (For also heating model)

Air cooled water chiller adopts PE four-way valve from Unit State, so that solves reversing and system consume great problem exist in other same kind of products. 

5. Expansion valve:Thermal expansion valve

6. Condenser

1) Axialfan, protection grade reached IP55. long service ling and reliable.

2) External rotator and blades combined into integrity. Design compact, run in high speed and low noise.

Features of Air Cooled Chiller:

Wide capacity range:

1) The various type unit with range of cooling capacities from 80KW – 1000KW;

2) Each one has cooling only and cooling (heating) type;

3) There are integrity and modular structure;

4) Each one has regular computer control type and luxury computer control type;

5) Provide optional components of auxiliary electrical heater, build-in water pump, and paddle flow switch etc. according to customer requirements.

6) The unit may use no-standard refrigerant. It may be low water temperature type glycol for air cooled water chiller unit, or double refrigerants unit, air cooled compress condensing unit, etc. Please contact us for detail.

The unit has high efficient, less energy consume, and low operating fee features.

LUTE Company imports brand high EER semi-hermetic crew type compressor, condenser, and cooling accessories from world and adopt advance technology in air conditioning and control. High quality process equipments and testing-center to ensure the units have energy saving and reliable features.

Unit protection components

The units have thermal protection switch, overload relay, high/low pressure switch, paddle flow switch and delay-starting protection devices to ensure unit runs under safety, reliable working condition and unit is easy to maintain and repairing.

Modular design

Multi-modular units adopt module combined structure to increase unit’s flexibility in transportation, installation, adjustment and maintain and reduce fee for transportation, installation and equipment maintain.

Super low noise, operating quietly

1) Semi-hermetic screw compressor has operating steady, low noise, and less vibration features.

2) Brand condensing axial fan is used in the unit. The blades and exterior-rotor motor design integrally. The unit structure is simply with good air dynamic features and to ensure fan works under low noise and high efficiency.

Advance control system, steady quality and reliable features.

1) Micro-computer control intelligently, English display, and friendly interface. Operating information is clear at a glance.

2) High automatic management with completely features to realize unit start up and shut down, timing control, water pump control, malfunction alarm and self-diagnosis features. It has RS485/RS232 communication port and convenience for centralize controlling and lone distance monitoring and long distance control.

3) Micro-computer and electrical control elements are brand products and imported from world. The products has good quality, and reliable features

4) Micro-computer controller defrosts intelligently with accuracy and efficiency. The controller also has self-diagnosis, energy management; anti-freeze and operating mode automatically control abilities. The unit has protections of high/low pressure, anti-freeze, oil temperature, overload, phase sequence, and water lacking to ensure unit run safety.

Nice outline

1) Air-cooled condenser with upside down M shape layout to improve space using ratio, heat exchange area of air-cooled condenser and to reduce unit overall size;

2) The components and system pipes layout reasonable.

3) The shell of the unit pained with statically treatment. The color of shell may design by customer when order is placed. The stainless steel plate is also available for shell.

Save indoor space.

1) The unit may install on roof of the building, ground or other location, where does not need equipment room.

2) The unit uses high efficient heat exchanger. It adopts outdoor structure design and system matching with small volume, lightweight, and less area occupied.

Easy to maintenance

1) The installation of the unit is flexible. It can control at job site and long-distance

2) Open type structure is convenience for maintenance and reduces service space.
