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 patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:

Up to 90% less heat loss from insulated surfaces
Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
6× faster maintenance access than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
Typical payback under 2 years (some 9–11 months)

FAQ

Questions

How many iron & steel facilities does Canada have with tracked emissions?

8 facilities carry satellite-based CO2 estimates in our dataset (Climate TRACE 2023), totalling ≈13,515,276 t CO2/yr.

What is the largest iron & steel emitter in Canada?

Algoma steel plant — ≈4,932,009 t CO2/yr (est. 2023). Estimates are modelled, not verified declarations.

What would this CO2 cost at the CBAM price?

≈€1,019M per year at €75.36/t — indicative full-price value; actual cost depends on the EU-bound export share.

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.
