2 AHU Plus DX DX Air Handling Units AHUPlusDX-TH: DX Air Hadling Unit with 100% Fresh Air AHUPlusDX -IGK: DX Air Hadling Unit with 100% Fresh Air and Heat Recovery AHUPlusDX-KH: DX Air Handling Unit with Mixing Section Section Construction Structure DX Air Handling Units are formed from required modular sections according to need. Frame of modular sections of our Air Handling Units are manufactured from natural aluminum anodized profile and plastic corner connection elements. Thickness of section panels are 42 mm, outer wall is electrostatic powder coated and inner wall is manufactured from galvanized sheet. AHUPlus DX Air Handling Units are indispensable at central ventilation and ambient air conditioning applications due to its high efficiency and energy saving provided by its 70 kg/m³ dense Rockwool filled panels, modern frame structure, statically and dynamically balanced, quiet and efficient plug fans. Our electrical motors are 380V-50Hz as standard. High efficient plug fans with EC motor can also be used on customer demand. All double-walled panels are mounted to the aluminum frame by special torch tipped M6 nuts. Double-walled rigid standard inspection doors have gapless rigid hinge, lock mechanism that will not create protrusion inside of the section and will not allow air leakage. There are 180 mm high, full-length chassis feet manufactured from 2 or 3 mm galvanized sheet. There are slots and holes at the corner of the chassis feet for handling it with crane or forklift. All of the holes required for automation (differential pressure switch, NTC temperature sensor, frost thermostat etc.) are opened on DX Air Handling Unit at production stage. Motor connection cables are taken to the junction box. On demand, the unit can be delivered as all automation placed, adjusted and collected at the panel. Section connection elements are manufactured from aluminum alloy material. They have high structural strength for connecting the section from outside. The total number of use between sections varies according to the size of the model. There is interior lighting and sight glass at fan and filter sections. Thanks to these accessories, sections can be checked without disabling the system. 40

DX Coil Features DX coil means cooling the air by loading the heat taken from the air passing through the evaporator to refrigerant with the help of compressor.

3 DX Coil Features DX coil means cooling the air by loading the heat taken from the air passing through the evaporator to refrigerant with the help of compressor. To simply describe the system, a direct expansion-cooling coil is adapted to an Air Handling Unit and exterior VRF unit is connected to this coil to the extent it requires. While performing this operation, the refrigerant is evaporated at the source (AHU) where the heat transfer is made. In the transfer made by conventional cooling groups (chiller / hot water boiler), heat first transferred to water and then the heat transfer made inside the AHU via pipes and pumps. DX coil Air Handling Units condition the ambient air without the need for conventional cooling groups and even more with heat pumps, without need for hot water boilers. The main features sought at DX Air Handling Units can be listed as; operating efficiently while consuming low energy, air tightness, having construction that minimizes thermal bridges, not having vibration caused by dynamic forces. DX series Air Handling Units design and selection priorities are low operating cost and efficiency. We can list the following features in order to support these priorities; energy-saving fans, efficient heat recovery exchangers and coils, internal unit structure that provides optimized airflow. With our optional automation system, this efficiency can be taken to a higher level. 41

6 Advantages of DX Air Handling Units - The most important advantage is that there is much less energy loss at fluid pipes, - With high COP values, it is an advantageous system in terms of operating and investment costs, it provides new, easy and quick solution for small and medium sized facilities with only one investment, - Heating and cooling is performed by single external VRF unit, reduces operating costs for heating and cooling, - Thanks to compressors with variable capacity (inverter technology) and fans used, it provides optimal control, so that it is controlled locally and it consumes only required amount of power, - Ability to give fast response to partial loads, - Saving wide area required for water cooling group and boiler, - Taking into regime in short time, - There is no freezing risk of water coil in this system unlike conventional systems, - Having much lower maintenance costs than conventional systems, - Low noise level, - In this system, there is less static load added to structure comparing the static load occurred by the water circulating in steel piping, pump and pipes in conventional chiller and hot water boiler systems, - There is no need for closed are due to its suitability to operate outdoor, - Have long lifetime considering conventional systems. For system to work safely and smoothly, all automation scenarios are compatible with Heat Pump Outdoor Unit and is a package solution with DX Air Handling Unit automation. Automation is designed to make DX Air Handling Unit and Heat Pump Outdoor Unit is synchronized.
