Central Air Cooled Screw Chiller , High effiency Chiller 380V/ 3ph
/ 50Hz
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 where the 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 Chillers
1. 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.
1. Features:
1. Using imported international brands Germany (), HANBELL China
Taiwan 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 built-in 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, high-speed 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;
