What insulating one PowerDry dryer saves
The exposed burner and heat-exchanger surfaces run at 84–120 °C bare. Removable Inzonex modules cut that loss by ≈95% and bring the surface to a touch-safe ≤45 °C — strippable in seconds for maintenance. Indicative per-dryer figures below (gas, 7,340 h/yr).
Per exposed surface, one dryer (measured FLIR survey, gas, 7,340 h/yr):
| Exposed surface | Bare temp | Heat loss saved | £/yr (per dryer) |
|---|---|---|---|
| Front | 84 °C | 1.99 kW | £671 |
| Back | 120 °C | 3.57 kW | £1,204 |
| Top | ~115 °C | 2.32 kW | £781 |
| Sides | 100 °C | 1.43 kW | £483 |
| Per dryer (≈7.4 m²) | — | ≈9.3 kW | ≈£3,140 |
Indicative — heat loss per ASTM C680 with a ×1.40 surface-roughness factor, 7,000 operating hours/yr, gas. Per-face temperatures from a measured FLIR survey of Kannegiesser tumbler dryers. Actual savings confirmed per site with a free thermal survey. Surface ≤45 °C and up to 92% heat-loss reduction are Inzonex specifications.
