Hygienic, safe, certified – Synthetic air supply by WITT for medical applications

Synthetic air mixers by WITT-Gasetechnik offer highest supply safety for central gas supply systems in hospitals. The new product generation MED MG features high integrity when it comes to easy operation using a touch screen, low investment and maintenance costs, easy integration into existing systems and a low energy demand. The solution is certified according to European Medical Devices Directive 93/42/EEC.

Automatic Calibration

The operating costs and defective production of many technical gas systems can be reduced quickly if these are equipped with an automatic calibration unit. The function should be planned from the start, as a retrofit is usually not possible.

“Every measuring and analysis device for technical gases must be calibrated regularly if it is to function accurately”, declares Martin Bender of WITT-Gasetechnik, one of the leading providers. The manufacturers specify the interval. “An annual calibration is usually envisioned, but shorter intervals are recommended.” A so-called zero gas is initially connected for this. The device must therefore display a gas concentration of zero. If not, the display must be reset to this value by hand. A calibration gas with definite concentration is then connected, which has to be detected precisely. Only then is the proper functioning of the system ensured.

Witt introduces integrated moisture measurement for gas mixers

Witt, the market leader in gas mixing and metering systems and gas analyzers, announces new gas mixers with integrated moisture measurement which ensures the highest quality gas mixture for optimal manufacturing results. 

"Moisture in gasses can have a negative effect on the manufacturing process, especially when heat-treating metals," said Andreas Heyer, senior product manager. "When heat-treating metals, specially composed atmospheres are often used to ensure perfect and consistent processes. If the moisture level in the furnace is too high, it can have a negative effect on the manufacturing process," added Heyer.

Ventable in installed condition

Witt-Gasetechnik, the market leader in gas safety technology, announces it has developed a new venting function for safety relief valves. The SV805 A enables functional tests of installed Witt safety relief valves at any time.

“The new Witt relief valve SV805 A with straight design has been developed especially for venting with a connected blow-off pipe,” confirms Product Manager Andreas Heyer. “The escaping gas is not emitted into the ambient air but rather directly led into the blow-off pipe by using the venting function.”
