100-190 psigCROWNWELL 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 productionThe Know-HowMore 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 BenefitThe 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.Features: Direct
