Heavy duty Horizontal Expansion Tank
Heavy duty Horizontal Expansion Tank

Air-conditioner,boiler,heat pump,water heater; frequency-changing water supply ,constant pressure water supply solar power.

Used to absorb the increased water volume when the temperature in the heating system increases. To compensate the water volume in water supply systems. An expansion tank is divided into two chambers by a bladder or diaphragm.When pipes are filled with heated-transfer fluid,and the operating pressure of the system is set, the fluid will ocupy a given volume based on the temperature.This is where the expansin tank is critical. Without it,something would blow! The expansion tank allows the fluid to safety expand by compressing the air in chamber.

This working unit includes main bosy,bladder and water inlet/outlet and air inlet.It is made of stainless steel or baked -enamel coating carbon steel;the bladder is made of EPDM or butyl rubber;the compressed air has been filled before the product leaving the factory

Operating principle

When the bladder if filled with heat-transfer fluid,the nitrogen is pressed,so its pressure is rising until arrives at the same level with the water pressrue,water filling stop.When water run orff,the pressure is reduced, the expanded air force the water to feed system,and stop until the pressure arrives at the same level with the pressure of water
