This Year’s News Are Unveiled at MCE 2024 in March

We warmly invite you to join us at the Mostra Convegno Expocomfort 2024 in Milan from 12 to 15 March. As ever, we look forward to presenting our latest news and solutions, so do pay us a visit in Hall 11, stand C45/D48.

In the last year, we have finetuned our updates to our drives for ventilation systems (OJ DV Gen II) as well as our range of drives created specifically for scroll compressors (OJ DC). Perhaps most excitingly of all, we present our new AHU control system OJ Air Plus: Based on the OJ Air 2 range, it features all-new user interfaces, major hardware upgrades and more ports than ever. All three ranges will be on display – and we are of course ready to talk about our full selection of drives and controls and sensors for air handling units.

OJ Air Plus AHU controller OJ Air™ Plus

The star of this year’s MCE show is the new OJ Air Plus control system for AHUs. Based on the popular OJ Air2 system, it offers plenty of upgrades – including a major hardware update with added ports, a faster CPU, and more memory. All these features help make the OJ Air Plus system future-proof.

User-centric interface
The most immediate notable difference introduced in OJ Air Plus system is the all-new, user-centric interface. Based on end-user research, we have introduced five pre-defined user profiles – from facility managers to technicians, and factory engineers. This ensures that all user groups can easily and intuitively do exactly what they need to do – and that no mistakes are inadvertently made by those who shouldn’t have access to the more sophisticated features.

Customers are free to choose between many types of access: There are on-system touchscreens in 2”and 3.5” versions which offer selected functions for different user groups. There is the option to access via internal networks – or you can access the system over the internet via OJ Air Cloud. Service technicians will greatly appreciate the option to connect via a PC port or the system’s built-in WiFi. There is no need to access the client’s WiFi, which is also good news for their data security.

  • Five pre-defined user profiles – access only what you need
  • Intuitive operation – from simple settings to sophisticated drag-n-drop design and installation
  • Two touchscreen options: 2” and 3.5”
  • Packed with ports – 26 I/Os in total, 6 com ports in total + WiFi & USB
  • 3 x faster CPU
  • 64 x more memory

We are part of BITZER – and have adjoining standsBITZER logo

This year at MCE is a special one for OJ Electronics: We still have our own stand, and at the same time we benefit from having our new colleagues in the BITZER Group right across from us. So if you set up a meeting with us, we might take you across to use the BITZER facilities!


That is just one example of the many synergies you can expect to see from OJ Electronics and BITZER Electronics in future: We are combining our know-how to bring the entire HVAC+R industry even smarter, greener solutions. We expect to greatly benefit from sharing our combined insights into areas such as application know-how, laws and regulations, and green transformation initiatives. At the same time, it’s business as usual for you as a OJ Electronics customer: In BITZER, we have found another family-run company that shares our values and business approach. We look forward to exploring the future of HVAC together – and if you want to be introduced to some of our BITZER colleagues while in Milan, drop by and say hello!
