R134a scroll industrial chiller
H.Stars Group is industrial chiller manufacturers and we have been scroll chiller manufacturers more than 20 years. And we can offer the best scroll chiller price.
This series is developed, designed and manufactured by H.Stars Group for the refrigeration, cold storage, food processing, quick freezing and industrial cooling.The product is manufactured by adopting the combination of famous brand compressors and electronic control components. It is equipped with high-effciency fn condenser and evaporator. The unit is controlled by microcomputer and equipped with various protection functions which is high reliability, and can exert the highest effciency in the actual working conditions.
Fin Type Heat Exchanger
It adopts the hydrophilic aluminum foil to reduce the adhesion of water on the aluminum foil and greatly improve the heat exchange efficiency.
The aluminum fns are packed in the copper tube and features uniform wind speed. With reasonable arrangement of copper pipes, it is installed in "V"-shape to improve heat exchange efficiency and reduce fan noise. The copper tube and aluminum fn are mechanically connected through expansion which is high performance and stable heat exchange. It is independently designed and manufactured with strict quality control. Configuring according to the place of use and process, it ensures that the heat transfer coefficient meets the design requirements.
Compressor
The unit adopts famous brand compressor with center bearing cap to achieve high energy efficiency and low sound level. The unit runs quieter and more efficient, with the scroll design of "contact-free and wear-free", it can reduce friction.
Shell and Tube Heat Exchanger
The copper tube of the evaporator adopts 1.1mm thick copper heat exchange tube, which ensures that all products meet the high requirements of high efficiency, energy saving, safety, strong antifouling ability and durability. According to the customer's use conditions and water quality factors, different materials of heat exchange tubes can be selected, and the fouling coefficient can be increased to enhance the heat exchange efficiency, ensuring the high efficiency and energy saving and service life of the unit. It is independently designed and manufactured with strict quality control. Configuring according to the place of use and process, it ensures that the heat transfer coefficient meets the design requirements.
Fan
With special low-energy fan and reasonable fan nozzle design, it can maximize the air mobility and reduce the noise. Practice has proven that our fans run stably and have long service life. The waterproof and dustproof grade of the motor: IP54, insulation grade: F; every fan has a separate split cavity.
Controller
The controller adopts the highly integrated button-type human-machine interface control center, which greatly improves the anti-interference ability of the system. The product adopts plastic shell, which is easy to install. The front and rear panels exchange data through 485 communications, and the entire system can be integrated or separated. Siemens PLC controller can also be selected to realize Modbus RTU, TCP or S7 communication.
