3. Gentle function

All sizes are equipped with precise fan blades used in forward and backward centrifuge models. In addition, each zone of units is insulated using soundproofing in order to control unit sound (low dB).

4. Ease of installation and maintenance

Easy, fast, and secure accessibility of the inside space of air handling units, the proper position of the unit door, the appropriate structure of units, enabling the removal or displacement of parts, and full access to the inside of units for assembling parts are advantages of our air handling units.

Technical specifications of installed parts of the DamaTajhiz Air Handling Unit

• Chassis

The chassis is made of original u-channels proportional to the capacity of units and is coated by paint following welding and milling processes. Our units are equipped with expansion joints to avoid the transmission of vibrations to units.

• Structure

The mainframe of the DamaTajhiz Air Handling Unit is made of aluminium profiles (5 bends or 7 bends). Airlock thread grooves are made of polyamide or aluminium corners, depending on unit capacity.

• Insulator

The inside space of units is insulated by poly roll insulators in order to avoid heating and cooling losses.

• Fan

Air fans are centrifuge fans with forwarding or backward blades balanced statically and dynamically in accordance with NICOTRA design (proportional to unit design).

• Shafts and bearings

Shafts are made of CK45 steel ground and polished to resist wear and humidity. Bearings are made and assembled as self-adjusting bearings in accordance with the most reputable brand's design.

• Belts

Our units are equipped with V-belts (Korean-made). The belts are selected considering the safety factor of 25%. This increases the durability of the power transmission system of units.

• Electromotor

Our units use a 3-phase electromotor with a frequency of 50 Hz cooled by a fan driven by a motor rotor. This electromotor is in accordance with the IP54 standard with class F insulation.

• Coil

Damatajhiz uses four coil types in its air handling units: water coil, gas coil (DX), electric coil, and vapour coil. The outer surface of the coils is made of seamless copper tubes and the second surface is made of aluminium or copper fins, depending on the customer’s request.

• Filter

Our units are equipped with V-type aluminium filters with a thickness of 5 cm, and 7 washable aluminium net layers type G4 with high dust-removing efficiency. Bag-type filters with different efficiency can be installed depending on customers’ requests.

• Dampers

Air dampers are aluminium-made blades with airfoil shapes positioned in opposite directions. Strong propylene gears are used to rotate the dampers. The edge of the dampers is sealed with plastic sealing. A damper motor can be installed on the air dampers of our units.

• Access door

The fan room and filter room are equipped with hinged doors with propylene handles and proper sealing enabling easy access for maintenance operation purposes.

Installation considerations of the DamaTajhiz Air Handling Unit

•  After installing an air handling unit, an expansion joint (resin or plastic-o-foam joint) should be installed in order to avoid the transmission of vibration from units to the around of the foundation.
•  According to engineering standards, empty space with an area equal to 5.1 times the width of units should be considered for probable replacement of coil during the units life cycle
• For periodic services and cleaning operations, a wastewater channel should be made in the room of the air handling unit.
