PressureWave™ Series
Pressure Tank
Pressure Tank
PressureWave™ tanks are ideally suited for a wide range of applications, including booster systems, thermal expansion, irrigation systems, and hydraulic hammer arresting. The PressureWave™ Series is constructed of a virgin polypropylene liner combined with an FDA approved high grade butyl diaphragm.
HydroGuard™ Series
Shock Arrestor
Shock Arrestor
HydroGuard™ shock arrestors are built to reduce or eliminate hydraulic shock, otherwise known as water hammer. They do this by absorbing pressure surges within water or other fluids that are suddenly stopped or forced in other directions by fast closing valves. HydroGuard™ shock arrestors are best used at the point of shock and should be installed as close to the valve or piping where the shock originates from.
Challenger™ Series
Pressure Tank
Pressure Tank
Water Chamber, Patented Controlled Action Design: Efficient and cost effective, Challenger™ tanks are designed with a patented controlled action CAD-2 diaphragm assembly. It features a chlorine resistant 100% butyl diaphragm with a precision molded copolymer polypropylene liner for superior air and water separation.
C2-Lite CAD™ Series
Composite Pressure Tank
Composite Pressure Tank
If you are looking for the proven performance of a GWS steel tank in a lightweight composite design, C2-Lite CAD™ series is the answer. Efficient and cost effective, C2-Lite CAD™ tanks are designed with the patented controlled action diaphragm design of GWS Challenger™ tanks. Unlike other composite tanks that hide tired old bag technology in a plastic shell, the patented CAD-2 diaphragm design is stronger and will not crease and wear out.
HeatWave™ Series
Expansion tanks
Expansion tanks
With an incorporated hex nut system connection, HeatWave™ tanks are easy to install. Its air chamber sealed with a brass air valve and o-ring sealed air cap will provide many years of leak free and service free life. Its two part polyurethane, epoxy primed paint finish will withstand the harshest indoor and outdoor climates throughout the world. HeatWave™ tanks are quality tested at several stages on the production line to insure the structural integrity of every tank.
OneStop Plus
PLUG & PLAY SALT-FREE ANTI-SCALE & HEAVY METAL RED
PLUG & PLAY SALT-FREE ANTI-SCALE & HEAVY METAL RED
The OneStop Plus™ system is not a softener, it is a water conditioner designed to protect open circuit piping from limescale deposits. It can be installed as a Point-of-Entry device, for both cold and hot water, or as a Point-of-Use device, installed directly before the equipment that needs to receive treated water (saunas, dishwashers, washing machines, coffee machines, etc.).
C2-Lite UT
Composite utility tanks
Composite utility tanks
The C2Lite UT™ series is a range of lightweight composite utility tanks designed to withstand years of tough conditions. Unlike C2Lite CAD Series tanks, the UT series tanks are not fitted with a diaphragm and can utilize full tank volume for water storage. The tanks come with a heavy-duty base which has been molded out of high-impact ABS for maximum strength and durability.
MixMaster
Baffle tank
Baffle tank
The MixMaster™ series of composite baffle tanks are a superior alternative to traditional contact tanks found in many water treatment systems. MixMaster™ tanks utilize a patented internal baffle and diffuser system that redirects the treated water through a series of internal chambers. This unique baffle design creates turbulence which boosts the mixing of water and injected disinfectants such as chlorine or ozone, while nearly quadrupling the contact time compared with a standard contact tank.
