What is a screw chiller?
Screw chiller is a chiller with screw compressor and has more
cooling power than the scroll chiller.Air cooled and water cooled
screw chillers are typically available in 40 to 440 tons, higher
efficiency and reliability compared to scroll compressor.It's used
in both water and air chillers and are best for small to medium
cooling loads.
Features of water-cooled water screw chillers
1. Compressor
High-efficiency screw compressor with large cooling capacity from
120kw and 1600kw, it can achieve comparable part-load efficiencies,
whether you run your chiller more often at part or full load to
save energy.
2. Evaporator
Shell and tube evaporator, high-efficiency internally threaded
copper tube, with low flow resistance and high efficiency.
3. Condenser
The shell and tube condenser is low condensing temperature, good
cooling effect, suitable for medium and large refrigeration
system.It can run easily even in hot weather.
4. Control system
The control system is adopting Siemens PLC controller and LCD touch
screen , accurately controls the cooling capacity and cooling load
of the unit.
5. Safety Facilities
The chillers have multiple safety protection functions, such as
phase sequence protection, flow protection, high and low voltage
protection and overheating protection. High reliability, low
failure rate, long service time.
Process chiller benefits
1. Water-coold screw chillers could accurately provide the needed
temperature for industrial manufacturing and largely improve
efficiency and product quality.
2. The industrial water chillers are use to maintain constant and
precise control of the process temperature.
2. Chillers can decrease equipment depreciation and degradation to
cut down on operating expenditures.
4. The design is very compact and made of high-grade materials. It
has stronger durability and longer service life. It does not need
any kind of repair and replacement for a long time, which can save
cost.
5. These industrial screw central chillers are stable operation,
high efficiency and energy saving, which are ideal solution for
process cooling applications in Injection Molding, Blowing Molding,
Extruding machine, Thermal Forming, Beverage Filling processing,
Metal Finishing and much more.
