High-pressure regulators for NH3

High-pressure regulators, most commonly defined as single or first stage regulators, are perfect for demanding industrial and commercial tasks. They are perfectly suitable for blue-print machines and other tasks like heat treating that require a high heat output.

Product description

High Pressure regulators are designed to reduce and stabilise the pressure in NH3 and LPG containers to a safe and usable level. On high pressure regulators the output minimum is relatively high and remains around 500 mbar (7.2 psi). Each pressure regulator is precision-built with a multi-million BTU capacity and is therefore well-suited for tough jobs that require powerful and reliable equipment.
