Wide range of applications

Constructed of the highest quality steel, the HTX and SXHT are true work horses

HTX comes standard with a 100% butyl diaphragm

SXHT goes even one step further with our patented CAD2 diaphragm, offering even lower permeability rates at higher temperatures

Additionally, both tank lines diaphragms are oversized, which maximizes drawdown and minimizes wear

This design feature virtually eliminates diaphragm stretch, further promoting longevity

Seat located above drain

Top guided stem and non-stick disc to metal seat assures positive Shut-Off

High capacity

American Act Compliant

A pre-charged air chamber allows for system water expansion

The air charge is controlled via a charging valve located on the top or bottom of the tank
