A New Generation of
Compact Screw Compressors

Semi-hermetic Compact Srew Compressors
Series: BSR213 - BSR426

Our extensive state-of-the-art range has repeatedly set new standards in the compressed air business and offers a number of possible applications for any given task. In 1988, we successfully launched our first screw refrigerant compressor series, which has since been improved and developed continuously along with market requirements to meet our customers' highest demands. Today, the quality and reliability of Fu Sheng compressors are highly acknowledged by users in all industries and have gained an excellent reputation for their performance and reliability throughout the entire world.

Building on our valuable experience and superior technology, Fu Sheng is proud to now introduce a new generation of screw refrigerant compressors, the 2006 BSR series. Exceeding any previous compressor series' performance rates, the BSR series has become the best choice for all industrial applications. In addition to the proven elements featured by its predecessors from the SR series, the new compressors further improve the efficiency of any given system while at the same time offering compact design. No matter the desired application, the BSR series fully meets the requirement of each type of system including air conditioning, heat pumps, refrigeration and many more.

Superior quality, maximum efficiency and high reliability are Fu Sheng's priorities in developing innovative products for the compressor industry. Striving for our customers' confidence in creating the perfect solution for their requirements, we provide extensive service and use the best materials available to guarantee an exceptionally long service life. Our achievements have been confirmed by chiller makers all over the world. The BSR series was granted many international and domestic certificates such as ISO 9001:2000, UL, CE, PED and other important authentication.
