HTM services all common ventilation systems – from simple supply and exhaust systems and heat recovery systems to complex ventilation systems in industry, gastronomy and public buildings. Kitchen exhaust air systems in accordance with VDI 2052 are also part of our scope of services.
The VDI 6022 stipulates that air handling units must be regularly inspected for hygiene – to protect the health of building users. HTM carries out these inspections professionally, documents the results, and recommends targeted cleaning measures if necessary.
BSK stands for fire dampers. These must be regularly maintained and refurbished if necessary to function reliably in the event of a fire and to meet legal requirements. HTM takes on both the maintenance and refurbishment of BSK systems.
Initially, our technicians assess the condition of the system and ventilation ducts. Subsequently, the ducts, components, and filters are cleaned professionally – mechanically or with approved cleaning agents, depending on the findings. Finally, we fully document the measures taken.
The recommended maintenance intervals depend on the type of system, its usage and the applicable standards. The guideline is: at least once a year, and more frequently for systems in food processing or catering. HTM develops an individual maintenance plan for each customer, which takes all legal requirements into account.
We await your technical installations.
