Emerson Unveils HV-7000 Series Regulator for Hydrogen Vehicles Emerson has introduced the TESCOM™ HV-7000 Series, a two-stage pressure-reducing regulator aimed at enhancing fuel efficiency and reliability in hydrogen-powered vehicles. Specifically engineered for heavy-duty vehicles utilizing fuel cells or hydrogen combustion engines, these regulators ensure stable pressure delivery and extended service life.
The HV-7000 employs a two-stage pressure reduction system and a positive seal mechanism to maintain optimal hydrogen pressure under varying flow conditions, even as the vehicle’s hydrogen storage depletes. This design significantly reduces inlet characteristic decay compared to single-stage regulators, while the positive seal enhances shut-off performance, ultimately minimizing fueling costs and the risk of downstream component failure.
Fabrice Jannet, director of business development for hydrogen at Emerson’s discrete automation business, emphasizes the importance of reliable, fuel-efficient vehicles for fleet operators. The HV-7000 Series, engineered with automotive applications in mind, promises enhanced efficiency and reliability, facilitating easy integration for system integrators.
To combat the most common cause of regulator failure—contamination—HV-7000 incorporates features like tied valve stems, integrated filters, and patented redundant seals. These elements enhance contamination resistance, prolonging vehicle service life and reducing downtime.
Moreover, the regulator’s compact, lightweight design and specialized mounting facilitate quick assembly by fuel cell system manufacturers and integrators, ultimately reducing manufacturing costs and easing scalability.
