Hermetel clean room element systems

A clean room constitutes a separate closed area in a facility or building. Clean rooms are used for manufacturing, researching and performing activities during which it is possible to control and determine the conditions, excess pressure, and the amount of particles in the air, in accordance with the specifications. Our prefabricated products have the CE marking, in accordance with the standards EN 14509:2013.

Clean Room

Hermetel Oy's Clean Room system is comprised of the elements, the doors, the windows, and other necessary components that produce as little static electricity as possible, and which emits no particles.

Isolation rooms ISORO

The Hermetel isolation room ISORO is a new kind of way of building wall and ceiling structures, closed rooms, washing and social facilities based on the clean room premises, which require the hermetic structure of an insulation room. The structure is based on a modular element system and its accessories. The special conditions required by the premises are precise hermetics, fire safety category EI 15, and the sound insulation of the premises. The access control/closing systems of the doors have been accounted for in the system, with the Interock control.

Operating theatre OT-CELLA

The Hermetel operating theatre OT-CELLA is new kind of way of building the wall and ceiling structures of an operating theatre, based on the clean room principle, as well as the space required by the technology, positioned next to the theatre.
