More efficient, more effective and easier to handle for everyone involved
What is more, you can get everything you need from the OJ Air2 series: everything fits perfectly together.
The QuickPlug™ Modbus technology makes cabling and installation a breeze. But the Plug & Play philosophy goes further than that: With OJ Air2 controls inside, your air handling unit is in itself transformed into a single preinstalled Plug & Play-unit for remarkably easy installation on-site.
