Obsolete refrigerant fleet
Your R22, R404A, R134a are on borrowed time. Anticipate the F-Gas phase-out.

Modernise without replacing. Extend the useful life of your plant.
Rather than scrapping a still-working machine, we reconfigure the refrigeration cycle, swap high-GWP refrigerants for low-carbon alternatives, and bring controls back to state of the art. Economical, ecological, quick to implement.

Our approach
A modular approach: you choose the depth of works.
From a simple refrigerant swap to a full refurbishment of a production plant, each mission is scoped against your operational constraints and budget.
01
Targeted diagnostic
Detailed machine inspection, history review, precise identification of pain points.
02
Solution design
Refrigerant choice, sizing, updated refrigeration scheme, thermodynamic validation.
03
Execution
Works management: regulated recovery of old refrigerants, conversion, mechanical adjustments.
04
Commissioning & follow-up
Performance tests, control calibration, follow-up period with validation measurements.
Deliverables
What we hand over at the end of the mission.
Technical documents, measurable data, an immediately usable action plan.
Cooling regime optimisation
Floating condensation and evaporation setpoints, load-adaptive control, sub-cooling and heat recovery to maximise the COP.
AI-enhanced standardised controls
Controller upgrade with adaptive algorithms trained on the plant's operating patterns; seamless integration with the existing BMS.
Performance monitoring
Post-commissioning dashboard with automatic energy KPI logging and verification of actual savings over 6 to 12 months.
Regulatory dossier
Full DOE (as-built dossier), updated installation plan and operating procedures.
Use cases
When to refurbish rather than replace?
Compressors losing COP
Degraded performance but sound frame: refurbishment is more cost-effective.
Manual or obsolete control
Fast savings on consumption without touching the mechanics.
Food & beverage plants
Conversion to NH₃ or transcritical CO₂ for massive decarbonisation.
Commercial chillers
Cycle optimisation on chilled-water plants.
Technical rooms
Move to free-cooling, waste-heat valorisation.
