Features of the units

Possess 4th generation high-performance international level rotor profile with feature of bilateral asymmetric arc cycloidal. Being processed by advanced HOLROYD exclusive rotor grinding machine to ensure the most accurate precision and high efficiency.

Apply ductile iron stand for steel. Its performance of wear resistance, self-lubrication, sound insulation, damping capacity and low expansion coefficient are much better than that of steel rotor. All these performance prolong compressor service life and strong its reliability.

Apply imported JOHNCRANE mechanical seal. Simple structure, easy to install, superior sealing performance, all these features ensure compressor to be long-term and stable running.

Apply high quality SKF roller bearing take radial and axial force from rotor to precisely locating the rotor. Roller bearing can run over 40000hours and fully guarantee compressor running continually.

Apply small oil pump pressure difference technology to realize energy-saving.

The compressor has variable inner ratio structure and capacity regulating structure, which can ensure compressor running in highest efficiency under different condition and loading capacity.

Configure with double air make-up outlet, arrange air make-up in a more reasonable location and increase economizer performance in a large extent.

Design pressure can be reach up to 2.5MPa to ensure equipment running more safeAdopting the high-efficient oil separator and high-efficicent oil cooler to ensure lower oil comsumption and higher heat exchange efficiency;Adopting the steel valves wholly to ensure that the units are safe and easy to operate;Adding a pressure sustaining valve on the oil pipe to keep the oil pressure steady and improve the whole units' perfomance;Reasonable weight center and optimal foot bolt location to reduce the vibration and noise;Tidy piping and simply to operate; Two control modes of munual and micro-computer automation control;The key parts of controller adopt the imported high-quality and long service-term products, so that the liabilities can be increased further;Adopting the micro-computer controllers designed by the U.K. Guardian Controls International Ltd..Considering the advantages of several European and U.S.A. refrigeration companies' products and according to the features of Bingshan screw refrigeration units, the company develops the special micro-computer controllers to realize  the modulization and accessible to internet-connection, and also features good-appearance, convenient operation and friendly interface etc.
