TESCOM™ HV-3500 Series Regulators

TESCOM™ HV – 3500 Series Hydrogen Vehicle Pressure Regulators

The TESCOM HV – 3500 Series dual – stage pressure regulators are a reliable, low – pressure control solution. They are specially designed for on – board applications in industrial and commercial light – duty and heavy – duty hydrogen fuel cell vehicles. This design enables manufacturers to maximize fuel efficiency and extend vehicle range. The HV – 3500 can provide a consistent pressure and continuous flow under a variety of operating conditions. It is suitable for a nominal inlet pressure of 35.0 MPa, with a flow rate of up to 3.2 kg/H₂S.

Features
– Dual – stage and active seal design, providing a consistent pressure and continuous hydrogen fuel supply for fuel cells, reducing the risk of over – depressurization.
– Excellent shut – off performance.
– Corrosion – resistant construction materials.
– Designed for various vehicle operating conditions and various system pressure settings.
– Compact and lightweight design.
– The specially designed shape and standard mounting holes facilitate installation.
– Standard interfaces make it convenient for customers to integrate sensors and safety valves.
– Local production and support.

Specifications
– Nominal inlet pressure: 5076 psi / 35.0 MPa / 350 Bar
– Maximum inlet pressure: 6345 psi / 43.8 MPa / 438 Bar
– Minimum inlet pressure: 290 psi / 2.0 MPa / 20.0 Bar. Operation below this minimum pressure may limit the maximum flow rate.
– Design pressure rating: 150% of the nominal inlet pressure.
– Pressure rating: Complies with ANSI/ASME B31.3 specification.
– Seal rating: Gas – tight.
– Operating temperature: – 40 °F to + 185 °F / – 40 °C to + 85 °C.
– Flow capacity: Cv 0.17.
– Inlet pressure decay characteristics: 0.05 psi / 3.4 mbar per 100 psi / 6.9 bar change in inlet pressure.
– Filter: 10 microns. A 10 μm filter is used for initial system component protection. This product is designed for use with clean, contaminant – free hydrogen. Your system should be properly filtered before the regulator to prevent contamination.
