We carry out tests during production and keep a record of them. Every OTT diffuser is tested for leak-tightness after installation and the result is checked. Constant dimensional and visual inspections are also carried out during installation.
Spot checks with extended inspections supplement the quality control.
The OTT membranes are also tested for tear resistance.
