Why the Water Circuit Is Designed as a Closed Loop In a water-injected oil-free screw compressor, water serves as the compression medium — simultaneously cooling, sealing, and lubricating inside the compression element. Unlike an open system where water would be...

What Timing Gears Are and Why Dry Oil-Free Machines Need Them In a rotary screw compressor, two helical rotors — one male and one female — intermesh to trap and compress gas as they rotate. For the machine to work correctly without rotor-to-rotor contact, the two...

Three Jobs, One Medium — Why Water Works Where Oil Cannot In any rotary screw compressor, the compression element faces three simultaneous engineering challenges: the rotors must be lubricated to prevent surface wear, the rotor clearances must be sealed to prevent...

The Root Problem: Where Dry Compression Wastes Energy Every conventional dry oil-free screw compressor has a fundamental thermodynamic problem built into its design. With no medium inside the compression chamber to absorb heat, all the work done on the gas during...

Compression Thermodynamics: The Three Theoretical Processes To understand near isothermal compression, it helps to first understand what it is being compared against. Thermodynamics defines three idealised compression processes. Isothermal compression keeps gas...
