Description
Vulkan GPH 200 Gas Preheater
The Vulkan GPH 200 is a compact high-pressure gas preheater designed to stabilize gas supply in applications where pressure reduction causes strong cooling, icing or condensate formation. Its patented heating principle transfers heat directly into the gas stream, improving heat transfer efficiency exactly where it is needed. The unit is especially effective in systems with high withdrawal rates or low ambient temperatures and is equipped with an inlet filter for dependable operation. Core product characteristics such as the patented heating concept, inlet filter, 200 W heating power, 230 V / 50 Hz standard supply, and use in the high-pressure range are described in the manufacturer catalog and competitor product listing.
With the correct connection version, the GPH 200 is suitable for oxygen, inert gases, nitrogen, nitrous oxide, food gases, laboratory gases and general industrial gas duties. In practical terms, this makes it a highly versatile preheating solution for almost any standard high-pressure gas supply task where stable downstream performance matters. The catalog lists connection variants for oxygen, inert gas, nitrogen and nitrous oxide at pressures up to 300 bar.
For your product page, it should also be stated that the unit can be supplied with an EU plug, with a UK plug, or without a plug as cable only, and that a 110 V version is available.
The product is manufactured in accordance with the requirements of Regulation (EC) 1935/2004, Regulation (EC) 2023/2006 and LFGB, and is suitable for contact with food gases, as specified in your supplied wording for the page.
