Unpressurized Expansion Tank Cum Degasser System

Unpressurized Expansion Tank Cum Degasser System

Hike Automation’s Unpressurized Expansion Tank Cum Degasser System is an advanced and reliable alternative to conventional pressurized expansion tanks for chilled water–based cooling systems. Unlike traditional pressurized tanks that depend on pre-charged air and frequent bladder maintenance, this system operates at atmospheric pressure, offering a more stable and efficient solution for modern HVAC infrastructure.
