Heating appliance accessories
For accessories in the field of heating appliances that due to their innovative functions have not yet been covered by technical specifications, regulatory verification of fitness for use/application -
Single-room heating appliances
A single-room heating appliance is a heating appliance which serves to heat the room in which it is placed or installed. Heating appliances, chimneys -
Supply and exhaust ventilation units
Supply ventilation units serve to supply indoor spaces with filtered and possibly preheated outside air. Exhaust ventilation units serve to remove exhaust air from indoor spaces. Ventilation -
Ventilation units with heat recovery
Ventilation units with heat recovery serve to supply and remove air from indoor spaces while transferring the residual heat from the exhaust air to the supply air via a heat exchanger. Ventilation -
Single-room ventilation units in accordance with DIN 18017-3
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 -
Stair systems, steps and associated fasteners
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 for drains
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 for drains
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
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 -
Rehabilitation techniques for drains, sewers and manholes
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 for drains and manholes
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 -
Infiltration elements for property drainage
Infiltration elements form part of the property drainage system. They serve to store or retain rainwater. If infiltration elements are used on a property, it must be ensured that no dangers to the adj -
Central heating appliances
Central heating appliances ( Sammel-Feuerstätten ) are heating appliances that heat a medium (usually heating water) and provide warmth to a building via the ductwork and radiators. They are not to be -
Thermoplastic moulding compounds and moulded materials for pipes and tanks
Thermoplastic moulding compounds are used in a variety of ways to manufacture semi-finished products and construction products. They are used, for example, in the manufacture of bulk silos, cesspits a -
Filling systems
Filling systems are composed of branched filling lines (pipes) and are used to fill several tanks of a heating oil system or diesel storage system simultaneously (battery installation). Plastic tanks, -
Thermoplastic pipes and their fittings, seals and valves
Plastic pipes are especially suitable for conveying certain liquids hazardous to water because they often have a more favourable corrosion behaviour than metal products and hence are resistant to vari -
Collecting devices made of thermoplastic materials
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 -
Thermoplastic tanks
Thermoplastic tanks are especially suitable for storing certain liquids hazardous to water because they often have a more favourable corrosion behaviour than metal tanks and hence are resistant to var -
Special fire-resistant components in ventilation technology – duct components
Special fire-resistant components in ventilation technology are service duct components consisting mainly of a supporting tray, cladding, supply and discharge lines, electrical cables and ventilation -
Fire protection systems for ventilation systems
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 and shut-off devices for air ducts for exhaust ventilation systems in accordance with DIN 18017-3
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 -
Cesspits made of thermoplastic materials
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
