Emerson’s New Pressure-Reducing Regulator Improves Hydrogen Fuel Cell System Performance in Commercial Vehicles

FLORHAM PARK, N.J. (Nov. 29, 2022) — Emerson has launched a pressure-reducing regulator specially designed for use onboard commercial hydrogen fuel cell vehicles. The dual stage and patented active seal design of the TESCOM™ HV-3500 Hydrogen Onboard Regulator delivers steady pressure and constant hydrogen fuel supply to fuel cells in the full range of vehicle operating conditions, including acceleration, deceleration, stopping and idling. Stable pressure aids in extending fuel cell life and maximizing fuel usage. The reliable fuel pressure provided by the HV-3500 allows operators to drive farther without refueling and decreases the risk of over pressurization downstream, resulting in leakage, wasted fuel and possible emissions. The HV-3500 has been designed, engineered and independently tested to ensure compliance with EC79 requirements for pressure regulators used in hydrogen vehicles.
