DamaTajhiz Ceiling Ducted Split 18000 Model DT.DS.18

DamaTajhiz Ceiling Ducted Split 18000 BTU Model DT.DS.18 Buying Guide

The DamaTajhiz 18000 BTU ducted split model DT.DS.18 features a cooling capacity of 18000 (BTU/hr) and comes equipped with a factory-installed heating coil and a wall-mounted thermostat. It operates on single-phase power and is ideal for spaces between 35 and 45 square meters.
Using R410a refrigerant gas and a rotary compressor, the DamaTajhiz 18000 ducted split not only provides cool air but also uses a hot water coil for heating during cold seasons.

DamaTajhiz ducted splits are manufactured according to all technical standards, available in air capacities ranging from 18000 to 60000 (Btu/hr), suitable for residential buildings, large projects, and public facilities.

Thanks to the energy-efficient compressor, DamaTajhiz ceiling ducted splits for apartments up to 130 square meters can use single-phase units with a 32 Amp single-phase electricity meter, eliminating the need for three-phase power supply.

Technical Specifications of DamaTajhiz Ceiling Ducted Split 18000 Model DT.DS.18

1. Compressor
   • The DamaTajhiz 18000 ceiling ducted split DT.DS.18 uses a powerful, energy-efficient rotary compressor from a reputable brand (with product identification code and authenticity) and eco-friendly R410a refrigerant.
   • Each unit's compressor includes a tracking code to verify authenticity and prevent counterfeit products. Upon customer request, full purchase documentation from the manufacturer can be provided.
2. Fan Motor
   • The 18000 model features single-phase, three-speed electric motors with metal blowers or polyamide types, offering long life, low noise, and dynamic and static balancing.
3. Evaporator
   • A heat exchanger located inside the indoor unit responsible for absorbing heat and lowering room temperature.
4. Heating Coil
   • All ceiling ducted splits by DamaTajhiz are equipped with factory-installed hot water coils inside the air handling unit. This eliminates the need for extra space or cost to install a separate heating coil in limited ceiling spaces.
5. Construction of DamaTajhiz Coil
   • The coils are manufactured with the latest fully automated machinery, using advanced fin plate technology that provides higher heat exchange compared to similar coils.
   • Copper tubes are mechanically integrated with sinusoidal staggered aluminum fins using an expander machine, ensuring no air gaps between fins and copper tubes.
6. Drain Pan
   • The drain pan of the 18000 ceiling ducted split DT.DS.18 is made of high-quality galvanized steel or compact ABS, with proper slope to direct condensation water away from the cooling coil and out of the unit.
7. Body
   • The body of DamaTajhiz ducted split units is made entirely from hot-dip galvanized steel sheets, coated with two layers of electrostatic powder paint by fully automated machines.
8. Insulation
   • The inner body of the air handling unit is fully insulated with airo flex3 material to significantly reduce noise and prevent heat and cold loss.
9. Filter
   • DamaTajhiz ducted splits come with washable filters that remove airborne dust and lint particles and can be easily replaced or removed.
10. Thermostat

Important Tips for Buying DamaTajhiz Ceiling Ducted Splits

First, when selecting a ducted split, consider the size, capacity, intended use, and installation location. Ducted splits come in various cooling, heating, and airflow capacities, so knowing your space area, usage, and climate conditions is essential before purchasing.
To determine the required capacity and quantity of DamaTajhiz ducted splits for your project, we recommend sending your latest architectural plans to our experts.
After capacity and quantity are decided, the installation location is chosen based on several factors, such as the presence of false ceilings, duct routing possibilities, piping arrangements from the unit to the outdoor panel, hot water piping for heating coils, noise level considerations, and more.
Typically, DamaTajhiz ceiling ducted splits are installed hidden under false ceilings in apartment units and distribute cool or warm air through connected ducts to various rooms effectively.
Another crucial point after selecting the ducted split is designing a proper and engineering-based duct layout using optimal dimensions and paths. DamaTajhiz designs duct systems for projects following duct design principles and uses specialized software to provide the best solutions to buyers.
Regarding the cost of installing air distribution ducts and copper piping between the indoor and outdoor units, a rough estimate is about 20 to 30% of the initial ducted split purchase price. (This is an approximate estimate; the exact cost depends on factors such as duct material and type, duct length, distance between indoor and outdoor units, and other variables.)

Capacity Determination and Installation of DamaTajhiz Ceiling Ducted Splits

• To determine the required capacity and number of Damatajhiz ducted split air conditioners for your project, first send the latest architectural plans of the units and building floors via fax or email to our experts.
• Usually, when estimating the initial cooling capacity needed for each apartment in climates like Tehran, and for middle floors (which are not exposed to direct sunlight on the ceiling in summer or cold roof surfaces in winter), about one ton of cooling capacity (equal to 12,000 BTU/hour) is considered for every 30 to 40 square meters of gross apartment area. Therefore, if any apartment unit is larger than 120 square meters, it is recommended to use two ducted split units per unit.
• If your apartment units are even up to 200 square meters, you can still use single-phase ducted split units with 50 amp electrical power.
• One important factor in choosing and purchasing ducted split units is the airflow volume, which is frequently around 400 CFM (cubic feet per minute) per one ton of capacity. Obviously, lower airflow results in quieter operation, while higher airflow causes more noise.
• You can also refer to the approximate calculation table below to determine the required ducted split capacity based on the conditions and calculation principles mentioned:

- Note: This calculation is approximate and provided exclusively for residential apartments in climates similar to Tehran, with a ceiling height of 2.8 meters, without human crowding, without increased latent heat, without high-consumption electrical equipment, and without glass facades or glass walls—especially on the west-facing side of the space or building.

• After determining the required capacity and number of ceiling ducted split units, their installation location is decided based on several factors such as the presence of a false ceiling, ducting feasibility, piping route from the unit to the outdoor panel, hot water piping to the heating coil, optimal placement for noise control, and more.
• The duct layout from the ceiling ducted split unit to each room or hall is designed and delivered based on the optimal dimensions and routing above the false ceiling.
• Due to repeated questions from residential builders about the cost of installing air distribution and return ducts inside the units, as well as the copper piping between the indoor and outdoor panels, a rough estimate would be that installation costs are about 20% to 30% of the initial purchase price of the ducted split units. (Please note this is an approximation and may vary based on factors like distance and piping route between the indoor and outdoor units.)
• Before selecting and placing an order for any of the above ceiling ducted split units, make sure to check whether the required electrical power is single-phase or three-phase (Ø), and the required amperage (A), based on your electrical meter's capacity and specifications.
