Diaphragm expansion vessels

The correct pressure is the fundamental requirement for the proper operation of water based heating, solar, cooling and pressure booster systems. Here the Reflex diaphragm expansion vessels offer a simple and smart solution. They are independent of electrical power and easy to operate. Inside the vessel a diaphragm seals the system water from the gas compartment. So diffusion of pressured gas into the water is prevented. The result is a fully closed system that does not suffer from corrosion or other gas-related problems.
