Air Handling Unit

Specifications

  1. Customer need

Damatajhiz manufactures a wide range of air handling units in terms of size and type and designers can easily select the unit that best suits their project needs. Our units are manufactured in 15 main sizes.

  1. High durability

High-quality galvanized sheet, precise aluminum dampers, suitable insulation, suitable and easy oil lubrication, fan bearings and use of strong aluminum profiles are factors enhance the durability of our units.

  1. 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).

  1. Ease of installation and maintenance

Easy, fact and secure accessibility of the inside space of air handling units, proper position of unit door, 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

  • Chassis

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 main frame of DamaTajhiz Air Handling Unit DTH-150 is made of aluminum profiles (5 bends or 7 bends). Airlock thread grooves are made of polyamide or aluminum corners, depending on unit capacity.

  • Insulator

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

  • Fan

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

  • Shafts and bearings

Shafts are made of CK45 steel grinded and polished to resist against wear and humidity. Bearings are made and assembled as self-adjusting bearings in accordance with the most reputable brands 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 the frequency of 50 Hz cooled by a fan driven by motor rotor. This electromotor is in accordance with 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 vapor coil. The outer surface of coils is made of seamless copper tubes and the secondary surface is made of aluminum or copper fins, depending on customer’s request.

  • Filter

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

  • Dampers

Air dampers are aluminum-made blade with airfoil shape positioned in opposite direction. Strong propylene gears are used to rotate the dampers. The edge of dampers is sealed with plastic sealing. Damper motor can be installed on the air dampers of our units.

  • Access door

Fan room and filter room are equipped with hinged doors with propylene handle and proper sealing enabling easily access for maintenance operation purposes.

Installation considerations

- After installing air handling unit DTH-150, an expansion joint (resin or plast-o-foam joint) should be installed in order to avoid the transmission of vibration from units to the around of foundation.

- According to engineering standards, an empty space with an area equals to 5.1 times of the width of units should be considered for probable replacement of coil during units life cycle

- For periodic services and cleaning operations, wastewater channel should be made in the room of air handling unit DTH-150.

Please note the following items when inquire the price of air handling units required for your project

- Airflow (CFM)Air Handling Unit

- Return air volume

- Installation place

- Forward or upward blowing

- Unit size and configuration (horizontal or vertical)

- Static pressure of fan driving air inside canals. It varies proportional to the speed and power of units motor

- Number of rows, thermal level and number of fins per inch in heating and cooling coils

- Thickness of coil, casing sheet and frames of units
