Compatibility
The DX-KIT interface is the device that connects the direct expansion heat exchangers of the AHUs, air curtains and high-flow duct units to Hitachi outdoor units, in order to work in heating and cooling mode.
Regulation
With the option to regulate capacity according to the heat exchangers input and/or output temperature or using an external analogue signal, in accordance with cooling/heating requirements.
Total Integration
Its integration means air curtains with direct expansion heat exchangers can also work in cooling, unlike conventional curtains that only operate in heating mode.
Precise Temperature
The combination of DX-KIT with RAS-XH(V)NP(E) guarantees the highest levels of precision on the market in terms of maintaining the target temperature (air flow or room temperature).
All Elements Included
This kit includes: expansion valve, temperature sensors and electronic regulation devices.
Compatible with the Commercial range and VRF Set Free Systems.
