Safety gas bottle cabinet and gas mixer for 70 Nm³/h

Successful delivery and commissioning including integration and new approval of 27 year old pressure vessel

LT GASETECHNIK supplied a gas supply combination with a propane / nitrogen gas mixture for a manufacturer of quality stainless steel products based in Witten. The tailor-made and coherent concept convinced the customer. The supplied equipment efficiently and reliably produces the gas mixture of the highest quality.

When LT GASETECHNIK was awarded the contract to supply the new gas mixer in April 2020, the overall concept was one of the decisive arguments. The integration of an old 500 liter buffer tank was a major challenge. The order was completed on time with all dismantling services, new installation and commissioning by the LT GASETECHNIK team completed in July 2020.
