The Howden screw compressor is the “Mercedes G-Wagon” of rotary screws: over-engineered, expensive to buy and fix, but nearly unstoppable when properly maintained. It’s not for everyone, but for critical process applications, it’s a justifiable investment.
The slide valve and stepless capacity control are smooth. From 100% down to 25% load, the compressor maintains stable discharge pressure without surging. The Vi (volume ratio) adjustment is also effective for varying suction pressures. howden screw compressor
This development can increase evaporator capacity by up to 20% without significantly raising power consumption. The Howden screw compressor is the “Mercedes G-Wagon”
Including large-scale industrial and marine cooling. Metals Industry: Supporting specialized process solutions. Core Technology & Variations From 100% down to 25% load, the compressor
While not deafening, a Howden screw at full load produces 85–92 dBA without an acoustic enclosure. You will need hearing protection and/or a soundproofed room.
