– Hitachi DX-Kit: Versatile AHU Connection
The Hitachi DX-Kit for general AHU connection is highly versatile. It has a capacity range of 2HP to 30HP, with six different models available to meet your specific needs. The DX-Kit provides a flexible connection between Hitachi VRF equipment and your AHU, and offers several connection patterns:
- 1 VRF ODU to 1 AHU: 50% < Connection Ratio against ODU ≤ 100%
- 1 VRF ODU to 1 AHU (Separate Type Heat Exchanger): 50% < Connection Ratio against ODU ≤ 100% (Maximum number of DX-kit connections = 5)
- 1 VRF ODU to Multiple AHUs: 50% < Connection Ratio against ODU ≤ 100% (Different capacity AHUs can be connected)
- 1 VRF ODU to Multiple AHU/IDU: Connection Ratio against ODU ≤ 110%

– Precise temperature control
The combination of the DX-KIT with Hitachi VRF ODU ensures the highest level of precision in maintaining the desired temperature. It offers three types of AHU temperature control:
- Inlet air temperature control
- Outlet air temperature control
- Duty control
All three types of control can be chosen from two methods: capacity control or thermo-off control. Four different sensors (outlet air, inlet air, liquid piping, and gas piping) are included as standard accessories.

– Our direct expansion kit makes AC installation more flexible
Hitachi considered all the details to guarantee an easier and more flexible installation with the DX kit.
- It has an IP54 enclosure rating for the expansion valve box.
- The maximum total piping length can be up to 1000m.
- The height difference between the HVAC outdoor unit and AHU can be up to 50m.
- The thermistor length can be up to 10m.
- Plus, you can control and monitor it without needing to move from where you are using Hitachi's centralised controller, CSNET Manager, which is available through H-LINK connection.
