Solar thermal process heat

Collectors deliver 60–150 °C heat directly into washing, preheat and drying duties — strongest where sun and fuel prices are both high (the Gulf, southern EU).

How it works

Mechanism & sizing

Flat-plate to ~90 °C, evacuated tube/concentrating to 150 °C+. Best fits: daytime-coincident loads (CIP, washing) and preheat into existing boilers. Gulf plants pair it with the region's gas-price reforms — solar process heat is the no-carbon-price decarbonization play.

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

Solar thermal process heat, answered

What share of heat can solar cover?
10–30% of low-temp demand typically; higher with storage. Sizing follows the summer load valley, not the annual average.
Where does it pay best?
High-irradiance + expensive fuel: MENA, southern Europe, increasingly anywhere gas subsidies retreat.
Does it work with steam?
Preheat yes; direct solar steam exists (concentrating) but the robust economics today are 60–120 °C water duties.
