HRS – High Rise System
The High Rise System (HRS) maintains a constant pressure in a shaft exhaust system. Designed with EC-Flow Technology™, the HRS takes advantage of the LaundryFab bidirectional pressure transducer and proprietary PID technology to rapidly respond to varying pressures due to load changes in the shaft systems. Utilizing the DEF Dynamic Exhaust Fan and an L-series controller, the system runs continuously varying the speed of the exhaust fan to maintain pressure and providing an audible and visual alarm. The HRS meets all requirements for the National & International Fuel Gas Codes and the Uniform & International Mechanical Codes. The High-Rise System also offers available low-profile subduct risers which can reduce required size of the shaft by up to 52%!
