Installations

From a single cylinder change to the complete gas supply of your plant — from one source.

Everything from one source

Our application engineers develop the right supply model with you — including tank installations, pipework systems, pressure reduction stations, tapping points and pressure regulators. Installation, commissioning, inspection and maintenance are carried out by our own qualified staff.

What we build

  • Pipework systems
  • Pressure reduction stations for cylinder and bundle supply
  • Tapping points and pressure regulators
  • Tank installations for cryogenic liquefied gases
  • Gas engineering components and fittings

What we do

  • Installation and commissioning
  • Inspection and maintenance
  • Testing of safety equipment
  • Servicing and modernisation
  • Upgrading to the current safety standard

Advice, planning, delivery

Gas supply concepts

As gas consumption grows, moving from cylinder supply to a central solution begins to pay off. We analyse your demand, design the matching concept and implement it through to commissioning, including all safety inspections.

For larger volumes we store cryogenic liquefied gases in vacuum-insulated tanks, stationary or mobile. On request we install remote monitoring with automatic replenishment.

Your benefits

  • Continuous supply in sufficient quantity
  • Optimal pressures and temperatures
  • Fewer interruptions to production
  • Greater process reliability
  • Flexible and demand-driven

Available from stock

Tanks and tank installations

When consumption grows, a tank starts to pay for itself. We keep large tanks from 2,000 to 50,000 litres in stock or available at short notice, and agree the size that suits you individually.

We plan, build and operate tank installations for cryogenic liquefied gases such as oxygen, nitrogen, argon and carbon dioxide, as well as for LPG (propane). Filling is done by our own fleet — not by a subcontractor.

Stationary pressure tanks

For applications with a constant demand for gas under pressure. Stationary installation with vaporiser and pressure control line.

Vacuum-insulated tanks

For cryogenic liquefied gases such as oxygen, nitrogen, argon and CO₂, filled by our own road tankers, with remote monitoring on request.

Mobile tanks and vessels

Exchange and transport vessels for temporary demand or special projects — on request.

Supply at the workplace

Tapping points

Instead of a separate cylinder at every workstation, a central installation supplies your workplaces through pipework — with clear advantages for safety, maintenance and daily operation.

  • The right pressure where it is needed. Pressure regulators and reduction stations deliver exactly the working pressure each workstation requires.
  • Continuous supply. One central installation supplies several workstations safely and without interruption.
  • Matched to your gas. Design, connections and safety equipment are matched to your application and to the gas in question.
  • Safe in daily operation. Safety devices, tested components and properly routed pipework noticeably reduce the risk of accidents.

Keeping it running

Service and maintenance

So that your gas installation runs reliably: inspections, repairs and safety checks carried out by our own specialists.

  • Inspecting installations and checking their function
  • Repairing and replacing wearing parts
  • Testing safety equipment as required by regulation
  • Servicing existing installations at fixed intervals
  • Optimising and modernising during maintenance

Regular maintenance is carried out at fixed intervals. A due service can often be combined with an upgrade, for example to bring parts of the installation up to the current safety standard or to avoid downtime.
