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.

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.)
| Ducted Split Capacity | For Middle and First Floor Units (m²) | For Units Under the Roof (m²) |
| 18000 | Up to 45 | Up to 35 |
| 24000 | Up to 60 | Up to 45 |
| 30000 | Up to 80 | Up to 60 |
