Quality and safety in thermal processing plants

Process optimization using gas analysis

The use of WITT gas analysers ensures that thermal processes are protected and optimized. For example, an H2 emergency shutdown can be activated as a safeguard as soon as the H2 content of a mixture exceeds 5 %.  In this case, the H2 addition can be interrupted and automatically countered with nitrogen.

An automatic switchover to an emergency supply and a variety of other alarm-state actions are also possible. The gas analysers will monitor the precise blend of the forming gases, and can feed back to the mixers to keep the blend within the tolerance range you set.

Dangerous gas mixtures can be avoided with gas reverse flow protection

A further indispensable point for the perfect and economic protection of the thermal process plant is the use of gas reverse flow protection to avoid the formation of dangerous gas mixtures. WITT’s range of ultra-low opening pressure and ultra-low pressure drop non-return valves offer the definitive solution, ensuring safety even when every millibar counts.

The use of gas mixers combined with gas analysers and non-return valves provides the user with comprehensive safety in handling flammable gases and protects the person, the machine and the product. This is what the name WITT stands for: high reliability, precision and safety.
