Korea Cowell dry screw
● low power consumption, 30% lower than the current design, saving a lot of efficiency costs.
● greatly reduce the exhaust temperature, close to the requirements of T4.
● improved performance and vacuum level.
● small and compact design reduces installation space.
● most of them adopt c-flange design, which simplifies the installation and reduces the noise level, and there is no need for shaft positioning.
● exhaust cooling purification is not required. (for sizes H120, H200 and h320)
● features of screw type dry vacuum pump include:
● dry operation without oil and water realizes a clean vacuum environment.
● there is no metal contact between the screw and the shell to ensure the long service life of the pump.
● the newly designed screw rotor has high volumetric efficiency.
● oil or water is not used as the transmission medium of the pump, which reduces the operation cost.
● single stage design makes it easy to discharge solid waste and eliminate residues in the pump.
● the air passage through the pump is short, so the gas can be discharged quickly
● after adopting optional special coating, it is suitable for extracting toxic gas, corrosive gas and condensable gas.
● simple design, easy implementation and maintenance.
● low speed to achieve low vibration and low noise level.
● mechanical seal to prevent leakage.
