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 MEF Multi-use 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.
