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. 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.
We are always happy to create customised features for our clients, including features for private label solutions. So if you have special requirements, please do not hesitate to contact us. We can help you assess whether such customisation is feasible – and how to achieve what you want to do.
The OJ Air2 system has been specially designed to control air handling units and forms a complete control system where all components are fully integrated and optimised.
OJ-Air2-HMI-35T is a user-friendly control panel for installation within an air handling unit or on the wall in a room. The panel is used together with an OJ-Air2Master.
The touch control panel is ideal for adjusting the comfort level in kindergartens, workshops, sports centres, petrol stations and so on
The OJ Air2 Fan IO 21 is specially designed for mounting in the fan section in an air handling unit.
All functions for controlling heating/cooling valves, dampers, fan, filter monitoring and temperature measurement are built-in.
The OJ-Air2FanIO minimises the internal cabling in the air handling unit and significantly reduces the risk of installation errors.
The OJ Air2 Ext 45 extension module is used in AHUs with a high level of functionality, where eg a DX cooling section is included.
The OJ Air2 Ext is an extension module that is used in air handling units with high functionality, where extra components have been incorporated that need to be controlled and monitored.
The OJ Air2PWR80 system has been specially designed to control air handling units and forms a complete control system where all components are fully integrated and optimised
The OJ-Air2WP55 is used when the ventilation system is heating a room, and the user needs to be able to adjust the temperature setpoint.
The OJ Air2 range includes two different touchscreen interfaces: the 2” HMI-20T for everyday users, and the 3.5” HMI-35T for a full range of functions.
The compact 2” HMI-20T interface gives everyday users simple control, allowing them adjust the temperature setpoint and fan speed for the entire ventilation system via the intuitive touchscreen panel. Installation is very simple: the unit clicks in place in seconds.
The OJ-Air2-HMI-35T is a larger, more complex user interface for the OJ Air2 range. It covers the full range of functions – system configuration, set-up, maintenance and troubleshooting.
All system values can be viewed by all users, which means that passwords are only required when you want to edit the settings.
Operation is straightforward and intuitive: the menus are logical and easily navigated – and they use familiar symbols so that all users are up to speed right from the beginning.
You can include both models in your system if you wish. For example, the simple HMI-20T interface can be installed in an office for everyday users, while an HMI-35 model is placed in a technical room where service technicians can use it to access more sophisticated options.
