Cell Structure
In Veloterm air handling units, the cell is made with a specially drawn aluminum corner profile, intermediate profile and panels. The sealing and joining of the carcass is provided by specially designed aluminum corner profiles. EPDM gasket is used to ensure the tightness between the panel and the carcass. Air handling unit panels are specially designed to be able to be disassembled from the outside and intervened inside the air handling unit frame. There are no recesses or protrusions on the inner surfaces of the power plants. As a standard in air handling units, bases are made of galvanized steel of 2 mm thickness and 120 mm height. Base connections are made with bolts and nuts without welding.
Profile Structure
It has two profile structures, aluminum and galvanized steel. The aluminum profiles used are min. It has a wall thickness of 1.8 mm.
Panel Structure
The panels and doors of the air handling unit are produced as double-skinned in 60 mm thickness. Outer panel surfaces are produced using RAL 9002 protective polyfilm coated paint, inner surfaces galvanized, stainless or dyed sheet. The minimum sheet thickness is 0.8 mm and the rock wool used as insulation material is in A1 fire class. Roof sheet can be added in air handling units upon request. There are also labels containing technical information on the switchboard.
Insulation
Rockwool insulation is used with a density of 70 kg / m3.
Dampers
Dampers are sized to pass 100% air flow as standard. Damper frames are made of extruded aluminum. Double-walled blades are made of aerodynamically opposite action aluminum material for minimum resistance.
Serpentines
Coils are made of copper pipes as standard, aluminum wing frames and collectors are made of galvanized steel. Battery connections are provided as threaded. If requested, the connections can be flanged, the serpentine frame stainless blades are coated with epoxy and / or hydrophilic, and the collectors can be made of copper. The assembly sheets of the coils are slideways and are designed to be easily taken out for maintenance and cleaning. Serpatines can be made with water or dx.
Filters
It is important for the efficiency of the filter that the air flow rates specified in the technical catalogs of the filters are equal or more than the flow rate of the selected air handling unit. Considering this krtier, the entire cross section of Veloterm air handling units is used as a filter transition area in accordance with international standards. Filters are cassette type and can be easily installed and removed. An empty cell is left in front of the filter cell to remove the filters. Optional filters are used, and generally filter types are coarse filter, bag filter, compact filter (rigid), hepa filter and active carbon filter. Optionally, a manometer can be mounted on the cell.
Heat Recovery
Nowadays, since energy saving is very important, plate, rotor, battery and heat pipe type heat recovery elements can be used in air handling units depending on demand.
Fans
Fans are selected by taking into account high efficiency, minimum energy consumption and low noise level to meet the air flow and total static pressure. In the power plants, forward or backward inclined centrifuge, Plug and EC fans, which are statically and dynamically balanced in accordance with international stadans, are used. Motors in Plug and EC fans are designed as direct coupled. There is an additional door with an additional grille to increase the safety of the fan cells.
Engines
In plug or centrifugal fans, asynchronous motors with a three-phase squirrel cage rotor, IE2 or IE3 efficiency and IP 55 protection class are used as standard. In EC fans, motors of IE4 efficiency class are used.
Moisturizers
Three types of humidifiers are used: steam, filled and atomizer.
Condensation Pan
In order to drain the condensed water in the cooling coil, humidifier and heat recovery cells, a stainless double inclined pan is used. The condensation pan includes the cooling coil collectors and the drop eliminator.
UV Lamp
It is used to destroy microorganisms that hold and multiply in the humid environment on the surface of the cooling coil in the air handling unit or in the condensation pans.
Accessories
Sight Glass, Lighting, Emergency Stop Button with Auxiliary Contact, Collective Siphon are provided as standard. Magnehelic or inclined manometer, maintenance switch, differential pressure switch, By-pass damper, Thermistor on request
