Liquid-tight collecting trays and devices are enclosures serving to meet the requirement for secondary containment under water law. They are used to collect and retain substances hazardous to water le

Tanks and collecting devices made of plastic are especially suitable for liquids hazardous to water because they often have a more favourable corrosion behaviour than metal tanks and hence are resista

Smoke dampers are shut-off devices for preventing the spread of smoke via air ducts. They shut automatically after being triggered by a triggering mechanism, which is actuated upon detection of smoke

Smoke detection and triggering devices are used for controlling and triggering fire and smoke dampers in air ducts of HVAC systems. Following smoke detection and the corresponding signalling, the fire

Fire-resistant air ducts that are assembled on site from CE-marked fire protective boards covered by a European Technical Assessment (ETA) issued on the basis of a European Assessment Document (EAD) a

Fire protection systems mainly consist of straight air duct sections, fittings, seals, connectors and fasteners, classified or unclassified wraps and shut-off devices for fire and smoke etc. They may

Fire dampers are installed in air ducts of ventilation systems in the area of fire-resistant separating elements to prevent the spread of fire and smoke along the ductwork to other fire compartments f

With linearly supported glazing, the glass panes are continuously fixed via a linear mechanical glass support (e.g. profile) with a glass insertion depth. The glazing system is installed in such a man

With structural sealant glazing, glass panes are bonded to frame profiles at the factory (primarily using silicone adhesive and with a linear adhesive bead). This prefabricated structural sealant glaz

A hold-open device is a system of devices or device combinations suitable for the controlled disabling of the function of closing devices. Hold-open devices may be used on fire doors, smoke control do

Cesspits are liquid-tight tanks, usually installed underground, for waste water containing faecal matter (sewage). Given that cesspits are not connected to the sewer system, professional emptying and

Cesspits are watertight tanks for domestic waste water containing faecal matter (sewage). Given that cesspits are not connected to the sewer system, professional emptying and disposal must be carried

Bulk silos made of plastics – glass fibre-reinforced polyester resin (UP-GF) or polyethylene (PE) – are vertical cylindrical containers with funnel-shaped bottom outlets. They are used, e.g., for stor

Limit switches are safety devices within the meaning of water legislation, installed in tank vehicles and acting together with overfill prevention devices to interrupt the filling operation before the

Various construction products that serve as safety devices within the meaning of water legislation and contribute to preventing damage to water bodies are referred to as 'special fittings for tanks fo

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

Cross-sectional reductions for existing chimneys are used for renovation and/or modernisation. The purpose may be to upgrade the chimney for operation under wet conditions or adapt the cross section o

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
