SFL TF1589 3 Zone Tube furnace with Hydrogen atmosphere

 The furnace is designed to meet all required regulations for the safe handling of Hydrogen gas. In principle, every tube furnace can be modified to safely work with Hydrogen. 

The system utilises an insulated stainless steel outer skin with a quartz cylinder process chamber which is water-cooled, and leak tight flanges are mounted at both ends. The tube furnace is able to provide heat treatments up to 1100°C even in a pure Hydrogen atmosphere.

The quartz tube is firstly put under vacuum by the attached pump to reduce the amount of oxygen within the chamber, vastly decreasing the process time and saving on the inert gas consumed. 

Once the chamber has pulled down to a reduces atmosphere the chamber is automatically flooded with inert Nitrogen gas prior to the introduction of any Hydrogen gas for safety.

The Inert Nitrogen gas is provided by a flooding tank system that is filled with the inert gas at pressure, to purge the remaining Oxygen out of the tube prior to heat treatment, the flooding tank once discharged is then automatically refilled.

The gas outlet system is connected to an afterburner for outgoing Hydrogen combustion. The gas inlet to the afterburner is heated to prevent any condensate formation in the system. The afterburner is driven by compressed air and propane gas. The afterburner will combust Hydrogen and all other gaseous by-products generated during the process.

All gases are controlled by means of a fully automated flow controller. In the event a malfunction is detected, the system is immediately brought to a secure state. All devices are manufactured to adhere to SIL2 standards.

A Hydrogen sensor is installed in the enclosure and in the event that a Hydrogen leak is detected, the sensor immediately responds. If a Hydrogen leak is detected, the furnace is flooded with inert gas, and the system is brought to a safe status.

The Eurotherm Furnace controls are programmed with an intuitive and user-friendly touch panel interface.
