CROWNWELL COMPRESSOR - HIGHEST STANDARD
SIMPLICITY BUT NOT SIMPLE
For three generations, customers from mechanical engineering, industry and trade have relied on CROWNWELL know-how when it comes to planning, developing and manufacturing compressed air systems. They are fully aware of the fact that CROWNWELL AIR is more than just ordinary compressed air: utmost safety, outstanding efficiency, excellent quality, maximized flexibility along with dependable service are the ingredients to transform CROWNWELL AIR into air to work with - in China, in Asia and in more than 102 countries around the world.
The III generation, the basis for economical compressed air production
The Know-How
More than decades of know-how in manufacturing for the compressed air market. World wide knowledge in different compressed air applications have guided the development of customer specified stationary screw compressors.
Technical Advancement for your Benefit
The advantage of CROWNWELL lies in its simplified construction. Fewer components are utilized. This means a 60% reduction in main and wearing parts and over 70% fewer pipes and connections. In turn, this greatly reduces the risk of leakages, making the system environmentally friendly. Safe direct drive operation without V-belt transmission.
The CROWNWELL Screw Compressor works in the following way:
Ambient air is drawn through the intake filter and the multifunctional control system into the screw compressor block. This block consists of a pair of screw rotors. The main rotor, driven by an electric motor, takes the secondary rotor with it. The air is drawn in by the rotation of both of the interlocking rotors and is continually compressed. During rotation, coolant is injected into the rotors and forms a hydrostatic film between the main and secondary rotors. The function of the coolant is to seal the rotors, lubricate the bearings and adsorb the compression heat. Before compressed air leaves the compressor ( at 80 ºC approx.) it is separated from the coolant before being cooled in the aftercooler to approx.. 8ºC to 12ºC above the ambient temperature. The coolant then passes to the thermostatic control block and filter, before entering the cooler where it is cooled from approx.. 80ºC down to 50ºC. It is then injected back into the screw compressor block.
