Steel Expansion Tank Compression

PSE Series

Compression tanks are designed to absorb expansion forces and control the pressure in heating/cooling systems. Although an older design it works well when the air is controlled and kept in the tank, not in the system.The compression tank has been used for many years and works very well in specific systems. Using a plain steel expansion tank makes the system an air control system. The air volume or air cushion above the water level in the tank must be controlled.

Tank Fitting & Drainer

TF Series

Tank fittings maintain an adequate air cushion to provide sufficient pressurization against fluctuations of water volume. Since air can be absorbed in water, the tank fitting maintains collected air within the expansion / compression tank. All free and entrained air collected by an air separator or other air collection device is routed through the tank fitting, allowing air to pass freely into the tank. The fitting restricts the flow of water between the tank and the system, resulting in lower tank temperature, minimizing air absorption. Under normal operating conditions, the tank fitting readily allows air to enter the tank.
