Wastewater treatment systems for compressor condensates serve to treat wastewater resulting from compressed-air generation in compressors to such an extent that the treated effluent can be introduced

Stand-alone safety devices for monitoring the opening state of a window ensure that ventilation systems and non-room-sealed heating appliances can be operated safely in combined operation mode. If the

Stand-alone safety devices with differential pressure monitoring serve to ensure that ventilation systems and non-room-sealed heating appliances can be operated safely in combined operation mode. For

Falsework beam clamps are connectors in falsework in accordance with EN 12812 with a mechanical fit based on contact pressure and friction. The contact pressure is activated through bolt connections.

Scaffold couplers in accordance with EN 74-1 or EN 74-2 are the most common form of detachable connectors in scaffolding. They usually provide an interference fit between scaffold tubes. Couplers are

Telescopic and non-telescopic props made of steel in accordance with EN 1065 or aluminium in accordance with EN 16031 are used on construction sites as temporary vertical supports during construction

Dust separators are used in chimneys to reduce the dust particle content of flue gases resulting from the combustion of solid fuels. Heating appliances, chimneys

Waterproofing sheets and membranes are available for various applications (e.g. for roofs or elements in contact with soil). Waterproofing sheets and membranes can be divided into plastic and bitumen

Mastic or roller-compacted asphalt sealing layers are used in storage and filling facilities for manure, slurry and silage effluent (MSS facilities) and biogas storage and filling facilities (biogas S

Drainage channel systems and penetrations in retaining systems need to be designed in a way to ensure that no substances hazardous to water can escape from storage and filling facilities for manure, s

Joint sealing systems, e.g. sealing strips, sealing sheets, sealing tapes, coated sealing sheets and sealing compounds, serve to make construction joints in sealing surfaces or sealing systems of stor

Mastic or roller-compacted asphalt sealing layers are used in storage, filling and handling facilities for substances hazardous to water (SFH facilities) to create load-bearing, liquid-tight, sealed s

Semi-rigid sealing layers are used to create load-bearing surfaces in retaining systems, e.g. collecting rooms, collecting trays and surfaces, in storage, filling and handling facilities for substance

Joint sealing systems in SFH facilities Joint sealing systems, e.g. sealing strips, sealing sheets, compression profiles, extruded profiles, sealing tapes, coated sealing sheets and sealing compounds,

Steel and steel composite sealing systems serve to make retaining systems such as collecting rooms, collecting trays and surfaces in storage, filling and handling facilities for substances hazardous t

To create (load-bearing) surface seals for retaining systems, such as collecting trays, rooms or surfaces, in storage, filling and handling facilities for substances hazardous to water (SFH facilities

Balanced flue systems are room-sealed appliances, meaning that instead of using the air of the heating room as combustion air, outside air is supplied to the appliance. Balanced flue systems convey co

Chimneys for solid fuels serve to discharge flue gases from the combustion of solid fuels into the outside atmosphere via an outlet above roof level. They can also be used to discharge flue gases from

Single-room ventilation units ensure a controlled air exchange between the building interior and the outside environment which is independent of the ventilation behaviour of the occupants. Ventilation

A prefabricated stair system consists, e.g., of steps, landings, stringers, handrails, balustrades and fasteners. The following stair systems are distinguished: stairs supported by load-bearing bolts,

Pipes, fittings and inspection chambers are parts of rainwater or waste water drains for property drainage. They serve to ensure the safe discharge of surface water and/or waste water from the propert

Connectors (clamp connectors and/or couplings) for drains are designed to connect pipework parts such as pipes and fittings permanently such that no waste water can escape from the joints. In the case

Sealants for drains serve to prevent, in connection with pipework parts such as pipes and fittings, the leakage of discharged waste water. In the case of underground drains, the sealant also ensures t

Trenchless rehabilitation techniques are increasingly being applied in wastewater engineering today. For the rehabilitation of underground supply pipes and drainage pipes, techniques such as lining wi

Inner linings are prefabricated elements used for on-site lining of drains and manholes. They usually serve to improve corrosion protection. Inner linings must be fixed durably and tightly to the drai
