OJ Air2 - efficient Plug & Play AHU control

At OJ Electronics, we have spent four decades providing and perfecting control for air handling units. The OJ Air2 range makes the air handling unit more efficient and easier to handle for everyone involved. The OJ Air2 range is one of our customer’s enduring favourites, and it remains as relevant as ever. The latest addition to the range is a good example: the OJ Air2 master is BACnet certified and has beed added zone control, enabling AHUs to handle four different temperature zones directly.

The OJ Air2 range is about choice, too. If customers want the full benefit of sophisticated control and simple handling, they can install the complete range in their system. But they can also scale their system to match project specifications and give clients exactly the level of functionality and control they need.

The OJ-Air2 controls up to four zones directly from your AHU
