Custom Plants

The Fäth Group’s vertical integration is most impressively apparent in plant engineering. Our custom developed complete solutions – from chemical supply systems right up to complex piping systems – feature expertise from all segments. We accompany you along the entire journey: from advice, planning and design right up to installation.

Mobile membrane filtration system

in container design

For many companies in the timber industry, treating process wastewater is a key issue. The aim is to remove heavy metals and salts from the water, and re-use as much of it as possible for other processes.

For one of our customers, we built a plant that does just that and is highly impressive in two relevant criteria – efficiency and compactness. It was fitted inside a standard 20 ft shipping container, and equipped with filter racks, pumps, measuring equipment, PP tanks in three different sizes (2000 l, 800 l, 200 l ) as well as a collection tray. The piping was installed in two different pressure stages.

The result is a plant that allows up to 90% of the water to be recovered by combining ultrafiltration with downstream reverse osmosis. The membrane used is cleaned by an integrated CIP (Cleaning in Place) station with a separate CIP cleaning tank.

"GasServant-800"

Fully automatic gas cabinet

The GasServant-800 is a fully automatic supply system for withdrawal from liquid and pressurised gas cylinders. The redundant design ensures a continuous supply of gas. The system automatically switches between the two supply lines as required. All process parameters are monitored continuously.

The gas cylinder connection via triple rinsing blocks and a system-controlled rinsing procedure ensures maximum security for the operator when changing cylinders – while also minimising the rinsing gas consumption at the same time. Other safety features protect against leaks, overpressure and fire hazards. Made in Germany using premium components, our gas cabinet meets highest quality standards.

Other equipment options depending on requirements:

Vacuum generator
Height-adjustable cylinder holder
Cleaning cartridge for exhaust gas
Bursting discs
Cylinder weighing scales for liquefied gases
Flame detector
Gas detector
Cylinder, panel and process line heating

Valve test stand for CIP/SIP processes

Diaphragm valves are used to distribute and metre fluids in process engineering systems. We developed a test stand to enable our customer Bürkert to efficiently test the stability of the valves they produce. By simulating cleaning cycles, the test stand assesses how valves react to the test media for CIP (Cleaning in Place) and SIP (Sterilization in Place) processes.

The test stand can expose up to 6 valves in sizes DN8 to DN100 to various media. They include acid and alkaline cleaning agents, DI water, compressed air, ozonated water, water vapour & vacuums. The custom plant is designed for pressures up to 10 bar and flow rates of up to max. 80 m³/h. The steam sterilisation heats the plant to temperatures up to 170 °C.
