Eliminate pump cavitation, reduce system operating noise, due to the oxygen-depleted water will reduce corrosion aerobic system, constant pressure water equipment company, to extend the device usage time, Xianning constant pressure water apparatus, since gas is freed from the water, will be pressure water equipment, heat exchangers attached to the surface of the gas bubble will not improve the heating efficiency degasser working time and cycle can be adjusted as needed, apply a single system capacity up to 150m3; can be more than one parallel, small footprint, easy installation, automatic operation, constant pressure water device Which is good, safe, reliable, easy maintenance. Constant pressure water device is a regulated water device, widely used in air conditioning, heating systems, water distribution systems, etc. It can replace the traditional expansion tank pitcher, can reduce the number of starts of the pump, can absorb some of the water system expansion easy to realize automatic replenishment, automatic venting, automatic pressure relief and automatic over-voltage protection.
