Hitachi is a highly trusted name in the world of oil flooded rotary screw compressors. Famous for their high-efficiency and noted for their regular easy maintenance, the 7.5 to 240 kW models with variable speed control inverters are among our favorites among the Hitachi screw compressor range.
A Long History of Expertise
The company, Hitachi, has a long history in the compressors marketplace, having launched piston type compressors way back in 1911. They regard themselves as leaders of the compressor industry and in modern times the models are low on energy usage so they can promote their environmentally friendly message while offering customers extreme cost savings.
The world’s primary flexible rotating speed compressors, by inverter control, were introduced in 1993 and quickly became their leading models. Bringing their history up-to-date and to meet their customers’ requirements, the Hitachi screw compressor series now includes the HiScrew 2000.
What Is a Screw Compressor?
For the uninitiated, the screw compressor uses a mechanism, by means of rotary displacement. It is a modern gas compressor that is often used to replace the old-style piston compressors.
Some individuals in the trade will refer to the Hitachi screw compressor as a rotary screw compressor. It works by forcing air into the sealed chamber, by using two opposing threaded screws. These rotors are designed to allow air to travel when they spin within the chamber. This forces the gas to become compressed, which is then forced through the thread.
There are two different types of screw compressors. The first doesn’t use lubricated seals in its chambers and is a rotary screw compressor. The second option is an oil flooded unit and is also a rotary compressor. This version is filled with a lubricating oil and becomes the dividing element between the two opposing rotors.
