Clean room is a contolled environment that is specified by the number of particles per cubic meter at a specified particle size. Typically used in every industry where small particles can adversely affect the company operation such as :

  • Pharmaceutical 
  • Medical Service Centre
  • Semiconductor Manufacturing Plant
  • Departement of Energy
  • Aerospace


The Frame - SAIVER unique frame design has inherent strength stability. The modular framework utilises a corrosion resistant, extruded marine aluminium alloy, patented twin ox section with True Thermal Break Construction. The entire module is subsequently mounted on a heavy sectional aluminium alloy or galvanized steel channel base.

Infill Panels - Standard 30mm or 60mm thick infill panels are of double skinned construction from pressure injected polyurethane foam insulation with "K" value of 0.02Watts/m°C and density 40kg/m³, sandwiched between galvanized steel with optional preplasticised or pre-painted finish, PRALLUMAN and stainless steel sheet is also available.

Accessibility - Filter, Coils, Air Washer and Fan Sections requiring regular maintenance and inspection, have hinged or fully removable access panels. These are fitted to the frame with easy release, half-turn nylon handles and cam locks. Handles can be operated internally for additional safety. Hinges are heavy duty, load-bearing design with stainless steel pivot. Other panels can be detached, if necessary for access by removing screws with simple hand tools.

Inlet Section / Mixing Box - Plenum completed with dampers are specifically designed to minimize the stratification of entering air streams for maximum efficiency. Dampers are assembled within a rigid extruded aluminium frame, flanged and pre-drilled for easy fitting to connecting ductwork. Dampers are opposed blade type and available in both flat and double skinned aerofoil sections. Blades are formed from extruded aluminium with edge interlocks. Gasekts are provided to minimize leakage of air.

Coil Section - Coils are computer selected to obtain optimum psychometric efficiency with low air and water pressure drops. Chilled water, direct expansion, hot water and steam coils are constructed from copper tubes, mechanically bonded to aluminium fins as standard. Other fin materials ate available as an option. The coil assembly as an option. The coil assembly completed with carbon steel, copper or stainless steel headers is located within the coil section on alumunium support for easy withdrawal from either side.

On Site Assembly - The lightweight construction material and modular nature of the units make them particularly suitable for lifting and maneuvering in difficult or confined locations. Modules can be easily aligned on site and locked together by sturdy stainless steel bolts, located in factory pre-drilled assembly holes. Continuous gaskets between each section ensure an air tight seal and thermal insulated. All fixings and gaskets are concealed within the unit. 

Filter Sections – Fully sealed filter sections are designed for east withdrawal and renewal or filter cells and, are constructed to house any type of primary or secondary filters of different media with varies efficiencies. In areas of particular importance, such as hospitals and clean rooms, absolute filters can be provided to ensure safe human and machine environments.

Fan and Motor Section – SAIVER manufactured fans form the heart of the systems. Forward curved or backward curved non-overloading aerofoil centrifugal fans are available with various outlet configurations. All fan wheels and pulleys are individually tested and precision balanced, statically and dynamically, and keyed to the shaft. Motors, mounted on slide rails with provision for easy belt tensioning, drive the fan with heavy duty V-belts. Combination spring and rubber vibration isolators are selected to match the power/weight ration of each fan for maximum isolation.


Intelligent Motor Control Center - SAIVER Integrated Air Handling System equips with various operative and control devices to optimize unit running conditions. Motor control panel (MCP module) and direct digital controller (DDC module) can be integrated into our SAIVER Integrated Air Handling System. All-in-one modular control center results a fast and simple installation as well as a flexible and reliable operations. A unit mounted feature means space and cost saving.

MCP modules

  • Inverter completed with EMC Filters to comply with EN regulations
  • Auto-by pass starting in case of inverter failure
  • Marshalling box for other services interfacing/connection, e.g. Fire Services/BMS/M&E.

Super Quiet Operation - Trough continuous Research and Development, SAIVER is capable to design and manufacture Acoustic AHU with much lower noise level. For VAV application, with the combination of plug and SIAVER Acoustic Panel, we are able to meet NC39 at 9.0m³ and 1000Pa without supply silencer.

DCC modules

  • DDC controller for local/remote controlling/monitoring
  • Chilled water valve completed with electronic control actuator
  • Water/Air differential pressure sensor
  • Water/Air temperature sensor
  • Micro switch adjacent to access door
  • Damper actuator at supply section
  • Probe type smoke detector at return air section
  • Carbon dioxide sensor at return air section
  • Filter differential pressure sensor


UV Sterilizing Light - An UV system intends to "capture and kill" airbone pathogens, improve IAQ and worker safety. The germicidal UV lamps in our SAIVER air handler disinfect the air by irradiation and provide full coverage of the target surfaces. Installation sights include coils, drain pans, filters, exhaust systems, or anywhere mold, bacteria and pathogens can be breed.

Ionizer - Ionizer ultimately destroys aiborne and living micro organisms by electrolysis process. the generator produces both positive and negative ions as the would occur under natural condition and the microbial control is performed by electrolysis (corona discharge) inside the Bi-polar unit. Single cell organisms are shocked/killed by the polar difference as negatively charged organisms collide with a positively charged particle. 

Heat recovery Unit - To improve Indoor Air Quality (IAQ), one of the best solutions is to increase the fresh air quantity. However, fresh air is always expensive no matter in winter and summer condition. A rotary heat recovery unit allows energy exchange between supply and exhaust air streams. This high efficient heat exchanger can reduce the annual energy consumption in AHU by as much as 90%. (Latent and Sensible Heat Recovery). Alternatively, Heat Plate is also one of the best heat recovery device which totally eliminates the potential problem of cross contamination.

Heat Pipes - Besides the heat recovery application, heat pipes are now widely used in dehumidification. heat pipes can increase an air handler moisture removal capability by 50% to 100%. The heat pipes not only reduced the chiller load by free pre-cooling but also provide free re-heating to lower the relative humidity of supply air. As most today's primary indoor air quality concerns are humidity related, the health benefits of pipes are noticeable. Run-around-coil is also an alternative solution to reduce dehumidification load on HVAC application.

Desiccant Package - SAIVER is working closely with desiccant wheel manufacturers in order to provide All-in-one dehumidification control system (able to reach below 10% relative humidity). Desiccant dehumidification ensures a hygienic and healthy environment by preventing the formation of moulds and fungi inside airstream
