HydroPanel II Series 450-4200 Shower System combines HydroGuard T/P water control with the convenience of modular shrouding. HydroPanel II's stainless steel shrouding provides a concealed shower system where in-wall piping does not exist or may not be practical. The single unit shower mounts easily onto preassembled copper tubing with just three screws. Behind the shroud, a HydroGuard 420 valve uses a thermal actuator to provide tempered water and adjust to supply water variances. The powerful thermal actuator quickly senses any change in hot or cold supply pressure or temperature and responds to maintain the user-selected temperatures. The motor will also shut off the hot water if the cold water supply pressure fails. HydroPanel II units can be used for new or retrofit applications, such as single showers or for complete shower rooms. They are ideal in schools, health clubs, factories, and remodeled older buildings. Optional hand-held showers mounted on vertical glide rails provide easy shower access for users with limited mobility. Optional HydroPanel II Modular Shrouding provides easy to install, interlocking stainless steel panels to conceal all exposed room piping.
