The UCR can operate with laminar or turbulent air-flow and meets the requirements for cleanroom classes 3.0 to 8.0 according to DIN EN ISO 14644-1 or M 1.5 to M 6.5 (100 000) according to US Federal Standard 209E.
The UCR system can be installed as an open or closed system, and available wall materials include simple PVC strip curtains or partition walls made of aluminum, steel, stainless steel, Macrolon or glass. Coated floors and raised floors made of aluminum or steel are also part of the system.
There are various possibilities to combine the different components. Complete solutions with integrated make-up air, exhaust air, self-contained cooling and controls are also available.
Self-supporting module sheet metal 1 provides the basic UCR construction, combined with stainless steel members with a standard height of 400 mm, connected to aluminium, steel or stainless steel pedestals. Either Ultraflex Ceiling Grid (types UFR-55/70-T/E and UFR-55/70-T/P) or Ultraflex Cassette Ceiling which is made according to EU-GMP or FDA can be used for the cleanroom ceiling. Filter Fan Units (FFUs), provided with AC motors or electronically commutated DC motors, supply the cleanroom with clean air (optional prefilter).
The UCR system comes standard with PVC curtains 6. The FFUs draw room air in and blow it through a HEPA filter into the working area, which is cleaned with a vertical, low turbulent air-flow. The contamination in the working area is pushed out to the bottom. In open systems the air simply flows out into the surrounding room. In closed systems the air returns through the return air chases and the plenum to the FFUs. To achieve this flowpath the UCR is installed with walls and plenum covers. Prefilters can be integrated in the return air chases of the ceiling system if required.
The length and width of the UCR can be determined based on the space requirements. Depending on the load of ceiling components a span of up to 4 800 mm can be built without any intermediate columns or hangers. The clear height of the UCR can be from 2 000 mm to 3 000 mm.
