ONYX-DIAG
ONYX-DIAG kit — full diagnostics: power, pressure and flow
Power alone is not enough: without pressure and flow, the system's real efficiency — and where it loses money — stays invisible.
On request
ONYX-360
ONYX-360 kit — complete monitoring: energy, air and air quality
Between two visits, nobody watches the compressor room: a drifting dryer or a major leak can go unnoticed for weeks.
On request
ONYX-RSD
ONYX-RSD kit — advanced rotary screw diagnostics (intermittent faults)
A specialized advanced-diagnostics kit for intermittent faults on rotary screw compressors — when the problem only shows up now and then, and no one-time measurement catches it.

CAL-EDGE-0
CAL-EDGE-0 — 4G data logger for compressed air
You don't know what your compressed air system actually consumes — no data, no basis for decisions.
On request
CAL-EDGE-8
CAL-EDGE-8 — audit logger with 8 analog inputs
The compressor controller isn't enough: you need independent pressure, flow and current measurements to audit the system.
On request
CAL-KIT
CAL-KIT — complete audit kit (logger + precision sensors)
Assembling logger, sensors and cabling piece by piece for every audit costs time — and there's always a cable missing once you're on site.
On request
CAL-SENSOR-WBOX
CAL-SENSOR-WBOX — wireless sensor module (W-Modbus)
Some sensors are too far away or too hard to reach to be wired back to the logger.
On request
Permanent monitoring
Continuous fleet monitoring and control: alarms, automatic monthly reports, sequencing.

CAL-EDGE-PM
CAL-EDGE-PM — permanent monitoring with analog inputs
No one watches the compressed air system between audits: efficiency drifts go unnoticed for months.
On request
CAL-PM
CAL-PM — full monitoring and control of the air system
Your compressors don't talk to each other: with no sequencer, they idle and fight over the same pressure band.
On request
CAL-PM-BASIC-4
CAL-PM-BASIC-4 — monitoring and control enclosure (up to 4 compressors)
You want to monitor and drive up to four compressors from a single panel, without having a custom system designed.
On request
Flow control
A smart valve that stabilizes pressure and cuts artificial demand (DN50 to DN200).
CFC
CFC — flow and pressure controller (DN50 to DN200)
The whole network runs at the pressure of the most demanding point: every extra psi inflates leaks and artificial demand.
On request
Leak detection
Ultrasonic detection: every leak located is quantified in flow and annual cost.
CALMS-ULD
ULD — ultrasonic leak detector with app
Leaks often account for 20 to 30% of the air produced, but without a detector they're inaudible in plant noise.
