Handling air to SAIVER®, is as natural as breathing.SAIVER® has been manufacturing high quality Air Handling Units for almost half of a century. The Series A1 Air Handling System is the culmination of experience over the years together with continuing improvement through Research and Development. SAIVER® Air Handling Units incorporate the 'finely tuned, value engineered cost effective design aided by computer coupled with human ingenuity.
The superior quality of the series A1 have also been recognized by the world, including the certification of EUROVENT.
SAIVER® team comprises of highly experienced Engineers and Technicians totally committed to produce one of the finest Double Skinned Air Handling Units range in the World to meet the requirements of most demanding Cost and Quality conscious customer.
SAIVER® has kept pace with the time and has always been ahead of its competitors. With automized production (directly from selection program), SAIVER® manufactures CUSTOM-MADE units economically, efficiently and quality assuringly. SAIVER® units incorporate the finest corrosion resistant materials, such as Stainless Steel, Marine Aluminium Alloy and Copper to ensure long years of trouble free operation in the most adverse conditions.
SAIVER® unique frame design has inherent strength stability. The modular framework utilises a corrosion resistant, extruded marine, aluminium alloy, patented twin box section with True Thermal Break Construction. The entire module is subsequently mounted on a heavy sectional aluminium alloy or galvanized steel channel base.
Standard 60mm & 88mm 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 galvaized steel with optional preplasticised or pre-painted finish, PRE- ALUMAN and stainless steel sheet is also available.
Filter, Coils, Air Washers 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 safe Hinges are of 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. Gaskets are provided to minimize leakage of air.
Coils are computer selected to obtain optimum psychometric efficiency with low air and water pressure drops. Chilled water, dire expansion, hot water and steam coils are constructed from copper tubes, mechanically bonded to aluminium fins as standard. Other fin materials are available including vinyl coated aluminium, copper, tinned copper and galvanised steel. For corrosive flow media, stainless steel tubes and fins are available as an option. The coil assembly completed with carbon steel, copper or stainless steel headers is located within the coil section on aluminium 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 airtight seal and thermal insulated. All fixings and gaskets are concealed within the unit.
Fully sealed filter sections are designed for easy withdrawal and renewal of 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 all 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 ratio of each fan for maximum isolation
