ET Pressure tank heat expansion vessel

Replaceable membrance pressure tanks

Carbon steel

MAX.Work pressure:3.5bar

Working temperature:

Epdm: -1 0°C/99°C

Precharge: 1.5 Bar

Working Principle: 

1.When the pressure of the heating system rise, the liquid is pushed into airbag and then the airbag expanses to compress the air 

between airbag and tank.The liquid will not stop entering until the pressure of air and system are the same.

2.When the pressure of the heating system drop, the air pressure between airbag and tank is higher than the system pressure, the 

liquid is pushed out into the system by the air,so that the system pressure will not drop too much.

By Carton, 1pcs/Box, and by pallets.
