Inzonex removable modular insulation on industrial equipment
Cut the tonnes at the source

Hot industrial equipment? Cut the heat loss.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes Inzonex Modular Insulation — snap-fastened modules engineered per temperature tier, not generic off-the-shelf jackets:

  • Up to 96% less heat loss from insulated surfaces
  • Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
  • 6× faster maintenance access vs standard insulation jackets and metal cladding/boxes — unclips and refits in minutes, no destruction
  • Inspectable — opens for corrosion-under-insulation checks, then refits like-new (generic jackets often don't survive removal)
  • Typical payback under 2 years — some sites 9–11 months
See Inzonex process-equipment insulation →Run the savings study

Every tonne you stop emitting is a tonne you don't have to report: cutting heat loss is a measurable, auditable Scope 1 reduction that flows straight into EU ETS, CBAM and your ESG / CSRD disclosures — not an offset, an actual emission cut.

FAQ

Questions

How many iron & steel facilities does China have with tracked emissions?
311 facilities carry satellite-based CO2 estimates in our dataset (Climate TRACE 2023), totalling ≈1,317,489,541 t CO2/yr.
What is the largest iron & steel emitter in China?
Angang Steel Co Ltd — ≈31,049,504 t CO2/yr (est. 2023). Estimates are modelled, not verified declarations.
What would this CO2 cost at the CBAM price?
The gross full-price value is ≈€99,286M/yr (all tracked CO2 × €75.36/t CBAM ref). Actual CBAM liability is far smaller: it falls only on emissions embedded in EU-bound exports, and only on the phased-in share — 2.5% in 2026 rising to 100% by 2034 (Reg (EU) 2023/956).
How this page is built: heat-loss figures follow ASTM C680 / ISO 12241 (the method behind our public calculators); facility emissions from Climate TRACE & EU ETS verified data across 30,000+ industrial sites; the 2026–2034 schedule is Regulation (EU) 2023/956, not a forecast.
