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

opening are used to seal revision openings in fire-resistant service ducts or suspended ceilings inside a building or structural work. They prevent fire or smoke from spreading via the revision opening from [...] suspended ceiling to the area below. Closures or closure systems for inspection openings consist mainly of a frame and the leaf or leaves. Closures and closure systems for revision openings are factory-made, need [...] need to close tightly all around; they may only be opened from the outside (i.e. from the room) with a special tool or key or similar. By definition, closures for inspection openings have one or two leaves

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 by the connected smoke detector. 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 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

Retrofit kits are systems consisting of multiple components which are installed on site in existing tanks forming part of the wastewater treatment plant. The retrofitted small wastewater treatment pla

The systems serve to treat wastewater from vehicle cleaning facilities to such an extent that the water can be reused in the washing process (closed-loop systems) or introduced into the sewer system.

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
