ONYX-360 kit — the compressor room under watch
The ONYX-360 kit puts the whole room under permanent monitoring: power and run status of every compressor, network pressure and flow, dew point at the dryer — all on an ONYX IoT server with online dashboards and alarms.
Field challenge
Compressed air failures are silent: a dryer drifts, a leak worsens, a backup compressor stays on. Without monitoring, you find out weeks later — on the electricity bill or, worse, in product quality.
Measurable benefits
Every critical value has its alarm threshold: drift is flagged the same day, not discovered at the next audit. The online history documents events and feeds maintenance. And since measurement is continuous, every optimization is verified by the data — before/after, in black and white.
Sized to your installation
Number of compressors, pressure points, dryers: the kit is sized through the configurator or during the quote. Data on a local server (closed network) or in the cloud managed by Onyx M3, flat-rate and included — your choice.

Frequently asked questions
Which alarms are configured?
The essential thresholds of a compressor room: pressure below the required minimum, dew point out of range (risk of water in the network), specific-efficiency drift and unexpected compressor operation. Thresholds are tuned to your installation.
Why measure dew point?
It is the air-quality indicator: a drifting dryer sends water into the network and damages tools and product long before anyone notices. Under monitoring, the drift triggers an alarm the same day.
Does ONYX-360 replace the CALMS platform?
No — the two solutions complement each other. ONYX-360 is open monitoring (Modbus + online charts), local or cloud, with no subscription. CALMS adds compressed-air-specific analysis, automatic monthly reports and compressor control. Several clients combine both.
