Kalshang PMV Series ( VSD ) Screw Equipment Energy-Saving
Energy efficiency is one of the most important factors all businesses are concerned with. The more efficient your air system, the lower your energy consumption and the cheaper your energy bill!
A vast amount of the energy that is lost in a factory or plant is due to wasted energy in an air Equipment installation. This can have a huge effect on energy costs, raising your bills and making your cost of ownership high. Various technologies have been developed to ensure that compressed air systems are performing as efficiently as possible, one such technology is variable speed drives (VSD).

What is VSD?
Variable speed drive (sometimes called variable frequency drive or regulated speed) Equipments use an intelligent drive system to continuously alter the motor speed to match the air demand. This drive controls the speed (RPM) of the unit depending on the demand, fluctuating the amount of power that is used to perfectly match the output required. When the demand slows, the compressed air system will reduce motor speed and thus the power consumption is also reduced.
Benefits of a Variable Speed Equipment
- No need to unload – the ability to start and stop under full system pressure.
- Reduced power costs – no loss of energy through running unloaded.
- Reduced power surges – avoid peak currents from starting air Equipment motor.
- More energy efficient – save 30% of the energy used by a typical fixed speed Equipment.
- Precise electrical control – motor speeds can be slowed down, brought to a halt or revved up.
- System leaks minimised – lower system pressure reduces the risk of leaks.
Could I benefit from a Variable Speed Drive Equipment?
Many air Equipment installations will benefit from the efficiency variable speed drive technology provides. Whether you are in the food and beverage industry, automotive, medical industry or even manufacturing, there will be times when your demand for compressed air will vary.
A combination of both variable and fixed speed Equipments is thought to be the most cost-effective and advantageous set-up, resulting in the most energy saved and demands met.
