Compressor features:

*The compressor adopts an international brand, a new type of high-efficiency pendulum rotary sub-compressor, which is 20%-30% more efficient than ordinary compressors, and has obtained IS9001 international certification quality with patents from Europe and the United States. *High efficiency 5:6 patented asymmetric rotor tooth profile.

+Capacity control can adopt four-stage (100%-75%-50%-25%) or three-stage (100-66%-33%) and stepless control system: *11 bearings and a-shaft The combined design of the thrust balance drum greatly increases the bearing life by 2.5-3.5 times.

+Using high-efficiency silicon steel sheet special groove design, and equipped with internal and external omnidirectional design cooling flow, so that the compressor motor can play the highest efficiency under any load.

The unique built-in oil pressure system does not require an oil pump and ensures that the compressor maintains the best lubrication effect. The oil separation adopts a double-layer filter method, which has a good oil filtering effect and the heat exchanger can exert its maximum capacity. *High efficiency, low noise, low vibration,

A variety of refrigerants are available, in addition to R22 refrigerant, environmentally friendly refrigerants such as R134a, R407c, etc. can also be used

A full range of compressor capacity ratios (VI=2.2/2.6/3.0/3.5) are available for selection, which can effectively avoid additional energy consumption caused by over-compressor or insufficient compressor.

In-Depth Expansion of Application Scenarios
In the industrial sector, air-cooled screw chillers serve multiple key industries with their exceptional performance. In the chemical industry, facing highly corrosive and complex working conditions, customized acid-proof and anti-corrosion units can stably cool equipment such as reactors and condensers, ensuring the safe operation of chemical processes. In the pharmaceutical industry, their precise temperature control meets the stringent requirements for ambient temperature in drug production, guaranteeing the stability of drug quality. In the electronics manufacturing field, these chillers provide ultra-low temperature and highly stable cooling environments for processes like chip manufacturing and LCD panel production, preventing precision components from being damaged by high temperatures. In commercial settings, such as large shopping malls, hotels, and office buildings, the low-noise and high-airflow characteristics of the units create a comfortable indoor environment, while the energy-efficient design significantly reduces operating costs.
  1. This air-cooled screw chiller eliminates the need for water cooling towers, saving installation space and costs. Its robust screw compressor ensures high efficiency, stable cooling, and low noise, ideal for commercial buildings and small factories with limited water resources.
