China Air Cooled Screw Industrial Water Chiller Builtin Unique Hydraulic System

Air cooled chillers absorb heat from process water, and the heat is then transferred to the
air around the chiller unit. This type of chiller system is generally used in applications wherethe additional heat it discharges is not a factor. In fact, it's often practical to use the excess heat to warm a plant during the winter, thus providing additional cost savings.Air Cooled Chillers Vs Water Cooled Chillers1. Air cooled chillers require less maintenance than water-cooled units.
2. Air cooled chillers do not require a cooling tower or a condenser water pump.
3. Consume approximately 10% more power than a water-
cooled unit due to wet surfaces transferring heat better than dry surfaces.
Unit Features:
1. Using imported international brands Darkin(Japan) or BITZER Germany (Bitzer), energy efficient compressor matches the quality of the condenser and evaporator, high efficiency, stable performance, Low noise, long service life Industrial PLC central control unit, the energy transfer system with the compressor can be timely efficiency in order to run the unit, lower operating costs;

2. Within the integrated water, low temperature, high pressure, freezing, phase, delay start, reverse, overload, motor overheating, oil pressure, and poor treatment a number of security features;

3. English user interface, menu prompts, can be set unit operating environment;

4. Volume control can be four sections (100%-75%-50%-25%) or three-step (100%-66%-33%) and non-stage control systems;

5. A unique builtin hydraulic system, no pumps are guaranteed to maintain the best lubricating effect of the compressor, oil separator with double filtration, oil filtering effect of good, can play a maximum capacity of heat exchangers;

6. Efficient thread copper tube to enhance heat transfer effects, more energy efficient. Using the latest CAD/CAM design and processing technology CNC machining center produced, compact structure, small volume, durable. U-beam structure of the tubes can be cleaned out within the overall scale, easy maintenance, to prevent refrigerant leakage phenomenon;

7. Use all imports of the corrugates steel pipe and hyperbolic hydrophilic aluminum foil, highspeed drilling, and other professional equipment manufacturers, is more closely exposed pipe and fin, heat transfer more efficient, with a small size, light weight, the advantages of more compact and reasonable;
8. No need to install cooling towers, cooling water pumps and other equipment for water scarcity and poor water quality areas. It can be installed on the roof, rooftops and other open spaces, no special room is needed, saving space;
Applications
Be widely used in plastics, electroplating, electronics manufacturing, pharmaceutical chemicals, food processing, refrigeration and other industrial establishments and guesthouses, hotels, shopping malls, office buildings and other types of civil air-conditioning system.
