A revolutionary design that pays its way. Complete systems and sub-assemblies.
After many years of integrating our water treatment units into traditional aircraft potable water
systems, our engineers recognized the need for a lighter, more reliable, and above all, freeze-proof
aircraft water system design. Building on our design and certification expertise, we developed and
patented the Circulating Potable Water System (C-PWS™) which can offer significant benefits over
traditional systems:
Freedom from Freezing: By keeping water in continual motion, the C-PWS™ has proven in service that it prevents freezing - even on long flights at high altitude.
Lighter weight: The C-PWS™ design allows the removal of a number of heavy traditional components to dramatically lower overall system weight.
Optimized Interior Space: replacing bulky pressurized water tanks with flexible conformal designs can open up previously occupied interior space for other uses.
Adaptable to a wide range of aircraft, the C-PWS™ has been installed and certified on Airbus A310, Airbus ACJ, Boeing 737/BBJ, Bombardier Global Express, and Gulfstream G-IV aircraft.
As well as the complete C-PWS system, we can provide sub-assembly kits for integration into custom systems as designed by major VIP aircraft completion centers. These kits can include a mix of tanks, pumps, water treatment units, valves and controllers with or without structural attachment details and electrical harnesses.
