Expansion Vessel,Pressure Tank,Expansion Tank,

 

Overview:

The thermal expansion tank has a chamber in which air is locked inside a bladder or diaphragm. When pipes are filled with heat-transfer fluid and the operating pressure of the system is set, the fluid will occupy a given volume based on the temperature. As the fluid is heated, it expands. This is where the expansion tank is critical. Without it, something would blow! The expansion tank allows the fluid to safely expand by compressing the air in the chamber. The size of the expansion tank needed depends on the total volume of fluid, which is determined by the number and size of collectors, and the length and diameter of the pipes in the solar loop.

 

Application

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 heat-transfer fluid, and the operating pressure of the system is set, the fluid will occupy a given volume based on the temperature. This is where the expansion tank is critical. Without it, something would blow! The expansion tank allows the fluid to safely expand by compressing the air in chamber.

 

Structure

This working station includes main body,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.

 

Principle of work

When bladder is filled with heat-transfer fluid, the nitrogen is pressed, so its pressure is rising until arrives at the same level with the water pressure, water filling stop. When water run off, 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.

 

Installation

In heating system such as air-conditioner,boiler,heat pump etc, installed in the backwater pipe.

Installed in the pump outlet.
