Ironers & Tunnel Washers (Laundry): Maintenance Access & Heat Loss

Q: How often are ironers & tunnel washers (laundry) actually opened?

Typical range: weekly — ribbon/belt access, jam clearing, steam chest checks, textile changeovers. Every one of those events pays the access cost your insulation system dictates.

Industrial ironers hold large hot steam chests centimetres from operators' hands, and tunnel washers hide hot water and steam sections behind guards. Both are opened weekly — access time is the whole game.

Opening frequency: weekly (ribbon/belt access, jam clearing, steam chest checks, textile changeovers). Access cost is set by the insulation system — unclip in minutes or cut-and-re-lag in hours.

Measured access times

Whole boiler house measured at 2–15 min per cover — the ironer steam chest uses the same multi-panel pattern as the economiser (15 min)

And the energy, while it stands bare

Surface state	Heat loss	Reduction
Bare at 160 °C	1,400 W/m²	—
Covered (50 mm stone wool, surface 32 °C)	115 W/m²	92% less
Saved on 8 m²-year	100,283 kWh · €5,014 · 18.4 t CO₂e

Quick-tier method: ASTM C680 / ISO 12241 1-D, combined outer coefficient h≈10 W/m²·K, 20 °C ambient, €0.05/kWh fuel, 8000 h/yr, 82% efficiency — same engine as the free calculator. Detailed site studies use v=0.5 m/s + explicit radiation and read higher.

Inzonex removable modular insulation on industrial equipment

From the people who publish this data

Components that get opened need covers that come off.

Inzonex makes modular removable insulation — engineered covers with snap-button closures, cores tiered by temperature (needle mat / wired mat / silica), surfaces held at ≤45 °C:

Up to 96% less heat loss from covered components
6× faster maintenance access than standard insulation jackets and metal cladding/boxes — unclips, refits, survives the cycle
Typical payback up to 2 years (hot, frequently-opened gear: 9–11 months)

How fast does a removable cover open here?

Measured on a live installation: Whole boiler house measured at 2–15 min per cover — the ironer steam chest uses the same multi-panel pattern as the economiser (15 min). Canonical: up to 6× faster access than standard insulation jackets and metal cladding/boxes.

What does running bare cost between jobs?

At 160 °C a bare surface loses ~1,400 W/m² (quick-tier, h=10, 20 °C ambient); a 50 mm engineered cover cuts that by ~92% and holds the skin ≤45 °C on typical duties. The table above turns that into kWh, € and CO₂ at stated assumptions.
