Water cooled Double-head Screw Chiller

The DY-FSQ series industrial screw chillers adopt famous, nice quality and brandnew screw compressor and the high efficiency evaporator and condenser, make them have big and good cooling effect. They are widely used in large refrigeration occasion and concentrated cooling areas. They always used as the host machine of central air conditioning project and other civil and industrial fields. For example:
For civil field: commercial buildings, entertainment centers, hotels, hospitals, theaters, stadiums and shopping malls etc.
For industrial field: plastic and rubber, pharmaceutical, textile chemical, food and beverage, electroplating and electronic industry etc.

Model: DY-FSQ280W

The energy efficiency degree has already been above the first level of national energy efficiency index.
Working stably, safely and reliably under the environment temperature of 0~45℃.
PLC Microprocessor control--easy to operate, accurately control temperature range from 3~50℃. Precision: ±0.1℃
Brandnew imported famous brand Semi-screw compressor, which ensures the efficient and stable operation of the chiller, that makes it has a longer service life, which generally can be used for 5 to 10 years.
The EER/COP is high, so it is more energy-saving than the general scroll type chiller.
Imported famous brand high-quality spare parts and domestic industry leading parts to ensure better performance for the chiller.
Own brand independently designed and developed high efficiency condenser and evaporator to ensure super refrigeration.
Well designed and reasonable pipelines--ensures power supply and saves energy.
Intelligent PLC touch screen control display--shows temperatures of outlet and inlet chilled water and each specific Error on(It is clear to know each Error) and provides visualized and direct setting; Can touch the screen to set and check the info.
Industrial designed-elegant and ergonomic.
Multiple protection functions ensure the comprehensive protection for chiller.
