HTX & SXHT Series - Hydronic Expansion Tanks

The HTX Series
Hydronic expansion tanks are the latest in a long line of quality products brought to you by Flexcon Industries. 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.

The SXHT Series
Designed for larger systems, these tanks utilize Flexcons patented double diaphragm design. Like the HTX tanks, the diaphragm is constructed of 100% butyl rubber

Specifications
The in-line HTX Series are available from 2 to 15 gallons and utilize a welded system connection with built-in hex nut for easy installation.The brass shrader valve has an o-ring seal to ensure air side integrity. An appliance quality finish means many years of service in damp basements and crawl spaces. The SXHT Series are freestanding, and range in size from 15 to 81 gallons.

Testing
Every Flexcon Hydronic tank is pressure tested and backed with a five year written, limited warranty.

Packages
Combination Packages include a tank, air scoop and vent for added installer convenience. Flexcon also offers a line of hydronic accessory items that include the re-designed Fill-Rite 300 FV pressure regulating valve.
