Take safety under contract
A D+H service contract offers many advantages.
As a building operator, you are responsible for the functional safety of the smoke extraction. A maintenance contract lets you show that you are meeting this obligation at all times. The D+H service contract naturally ensures regular, proper maintenance first and foremost. This gives you the security of having a SHEV system that will work reliably well into the future. But the D+H service contract also offers cost efficiency and transparency. It ensures that your expenditures for repair and safety always stay on budget and are easy to track.
