Special hardware, controls and software — through to audit-proof isolation.
Digital lockout-tagout systems and freeze/thaw plant for critical pharmaceutical and food processes — with our own controls, app connectivity and audit-ready evidence.
Two products of our own: digital lockout-tagout and freeze/thaw systems.
For both, we develop the controls and the software ourselves — and we commission them and document them so the record holds up to audit. The freeze/thaw hardware we build ourselves; for LOTO we integrate proven standard hardware.
Digital lockout-tagout systems carry isolation and release states right into the control system — with signable checklists and an audit trail. Freeze/thaw systems run temperature curves on our own controller — with recipes per product and documented runs.
Isolation and temperature control at a glance.
Isolation and release states run right into the control system; release follows the audit trail. The freeze/thaw controller holds the temperature along the stored setpoint curve.

From design through to operation.
The hardware is thought through during design and the URS, is built during construction and commissioning, and stays part of the plant in operation. That holds for lockout-tagout as it does for freeze/thaw systems — each in its own area of application.
Digital lockout-tagout systems.
Lockout-tagout protects a plant twice over: during commissioning — the first and every subsequent one — it makes sure the plant cannot be put into a hazardous state. And during maintenance, testing or modification it makes sure the plant cannot start up unintentionally. With us that isolation is digital: every lock carries an RFID tag. Its state runs over MQTT into the control system — and isolated actuators cannot be driven from software while the lock is set.
Scannable, signable checklists document every isolation and release step. As long as checks or documents are missing in the control system, the plant stays locked out — mechanically and in software. Only a complete, signed audit trail releases it.
Our freeze and thaw controller.
Temperature-sensitive products have to be frozen under control and thawed the same way. We run that temperature curve on our own controller — instead of leaving it to a bought-in, closed third-party unit.
Recipes hold the setpoint curve for each product. Every run is recorded in the audit trail with setpoint and actual values. An open API connects the plant to the control system and the documentation — this is where the real technical core sits.
Machine, controls, software and evidence — from one source.
01One responsibility instead of interfaces
Hardware, PLC, software and commissioning come from one team — no handovers between mechanical build and controls at the point where the isolation has to hold or the temperature curve has to be right.
02Software that enforces the isolation
Safety here is not only documented, it is technically enforced: locked out means locked out — until the evidence is complete.
03Audit-proof from the first step
Audit trail, signed checks and traceability run from the first isolation step — not only at handover.
04Project-specific, out of real plants
Freeze/thaw plant comes out of specific plant projects; for digital LOTO we integrate proven standard hardware into your process. Either way, the result fits your plant — not the other way round.
Frequently asked questions.
Lockout-tagout
What is digital lockout-tagout (LOTO)?
Lockout-tagout protects a plant twice over: during commissioning — the first and every subsequent one — it cannot be put into a hazardous state, and during maintenance, testing or modification it cannot start up unintentionally. With us that isolation is digital: every lock carries an RFID tag, its state runs into the control system — and isolated actuators cannot be driven from software while the lock is set.
How is the isolation documented so it holds up to audit?
Scannable, signable checklists document every isolation and release step. As long as checks or documents are missing in the control system, the plant stays locked out — mechanically and in software. Only the complete, signed audit trail releases it.
Do you supply LOTO hardware from a catalogue?
Yes. For digital LOTO we rely on proven standard hardware, configured for your project and integrated into your control system.
At what point in the project do you come in?
From the start: the hardware is thought through during design and the URS, is built during construction and commissioning, secures isolation and release across qualification and handover, and stays part of the plant in operation.
Freeze & thaw
How does your freeze/thaw controller differ from bought-in technology?
We run the temperature curve on our own controller rather than on a bought-in black box. Recipes hold the setpoint curve for each product, and every run is recorded in the audit trail with setpoint and actual values.
Do you supply freeze/thaw plant from a catalogue?
No. Every plant is built for the specific project, out of real plant projects — hardware, controls and software that fit your process and your product.
Can the controller be integrated into our control system?
Yes. An open API and modular integration via MTP (Module Type Package) connect the plant to the control system and the documentation.
