Clean Cold-Warm Rooms (FAS)

Applications

• Clean filling operations
• Sterility plate studies
• Cell and tissue culture
• Fermentation
• Media preparation

• Packaging under controlled temperature, humidity and clean room conditions
• General incubation and growth
• Vaccine production

• Clean room design standards from Class 100 to 100,000 available.
• Modular metal skinned panels with urethane insulated tongue and groove construction for chamber enclosure. All interior panel surfaces are a smooth nonshedding painted aluminum, galvanized steel, or stainless steel (recommended).
• "Cam-locking" clean room panel seams sealed with FDA approved sealants for a smooth cleanable surface.
• Internal stainless ceiling plenum housing mounted above lay-in tiles.
• Totally accessible hinged drain pan for maintenance and cleaning of all interior plenum components.
• PSC fan motors for energy efficiency. All fan motors rated for operating temperatures of chamber. Motors are remoted from chamber interior where application exceeds rating.
• Automatic defrosting with refrigerant hot gas and/or electric heat for quick and efficient operation.
• Uniform horizontal and vertical air distribution through ducted terminal lay-in HEPA filters in aluminum housings or complete pressurized plenum ceiling. Support achieved with anodized aluminum T-bar drop ceiling network. All solid "filler" clean room tiles constructed of nonshedding acoustical material.

• Perforated metal diffuser grills to protect terminal filter media.
• Terminal filters provided with adjustable air flow damper and static pressure port.
• Stainless false wall air returns at floor level are provided for ceiling plenums or air handlers. Returns feature gross mesh or pleatedfilters within "ledge" free channels.
• Sealed utility and sprinkler access penetrations.
• Semi-hermetic continually operating compressors for extended equipment life and maximum chamber temperature control and uniformity.
• Fully accessible control panel to efficiently and securely house all controls, alarms, and recording devices. "Ledge" free designs available.
• Touchscreen system control of chamber parameters.
• Fluorescent clean room style lay-in troffers or tear drop fixtures for chamber illumination.
• Factory leak testing of all refrigeration assemblies prior to shipment.
• Bench testing of complete control panel and electrical devices performed prior to shipment.
• Applicable ISO listing 9001:2000 applies.

• Magnehelic / photohelics provided for monitoring prefilter and HEPA pressure drop.
• Lowered classification zones within chamber for critical operations.
• Prefilter and HEPA loading alarms.
• Stainless wall, ceiling and floor finishes.
• Electrical wiring to NEC standards for Cl I Division I or II environments.
• Product security through dead bolts keyed to building. All security locking mechanisms are furnished with internal emergency relief.
• Flush thermopane view window in door or wall panels.

• Access ports and clean room pass throughs.
• Recessed duplex outlets within chamber walls.
• Seamless floor covering over complete chamber area with coving.
• Exterior/ interior door ramps.
• Pressurized anteroom or air showers for personnel entry.
• Emergency personnel lighting for chamber exit.
• Chamber airflow and pressure alarms (high and low).
• Emergency lighting systems.
• RS 232 / 485 or 4-20 mA comms available.

• Exhaust fans with stainless steel HEPA filtered air intake and housing.
• Base level dehumidification with a proportional reheat package.
• Extended range dehumidification by ES developed and field proven proportional air volume regenerative desiccant drier. This design allows close tolerance control and extended life of drier components.
• Humidification by independent passivated stainless steel steam generator designed for pure supply water.
• Air returns designed to be integrated into the insulated room wall panels.
• Copper or phenolic coated evaporator fin construction for protection in corrosive environments.

• Point of use water purification systems for steam generator supply water.
• Complete 100% redundant backup refrigeration systems with automatic switchover.
• Remote air handler can be provided to remove all mechanical components from above the suspended clean room tiles and eliminate the disturbance of the ceiling area and room.
• Available designs for temperature uniformity throughout entire chamber to ± 0.5°C.
• Available designs for humidity uniformity throughout entire chamber to ± 3 %RH.
• Conditioning packages designed to use host building chilled water systems for chamber cooling.
• Non-refrigerated cooling using building ventilation available for certain special applications.
