Flexcon HTX 30 Expansion Tank for Closed Loop Heating Systems for Heating Systems up to 150,000 Btu.

Flexon Expansion Tanks are constructed of deep drawn welded steel domes, HTX tanks feature butyl diaphragms engineered for longer life. Butyl rubber is the material of choice for American heating systems as it offers low permeability rates at higher temperatures. Our oversized diaphragm maximizes tank drawdown, and minimizes wear. This design virtually eliminates diaphragm stretch, which enhances longevity.
