The HRS High Rise System from LFSystems maintains a constant pressure in a shaft exhaust system. Designed with EC-Flow Technology™, the HRS takes advantage of the LFSystems bi-directional pressure transducer and proprietary PID technology to rapidly respond to varying pressures due to load changes in the shaft system. Utilizing the DEF Dynamic Exhaust Fan and an L150 constant pressure controller, the system runs continuous varying the speed of the exhaust fan to maintain a continuous flow in the shaft. The HRS also provides an audible and visual alarm in case of equipment fault.
The HRS High Rise System meets all requirements for the National & International Fuel Gas Code and the Uniform & International Mechanical Codes.
