FRP Insulated Boxes with Stainless Steel Liner
Passive cold boxes with a fiber-reinforced plastic shell, polyurethane insulation and a stainless steel liner. Phase-change plates hold the temperature without a power supply.

- Fiber-reinforced plastic (FRP) shell: rigid, light and resistant to corrosion.
- Polyurethane insulation layer.
- Stainless steel inner liner that is easy to clean and disinfect.
- Phase-change material (PCM) plates set the temperature. No compressor, no battery.
- Thick metal latches and reinforced handles.

How it is built
The stainless liner sits inside a polyurethane layer, and the FRP shell protects both. PCM plates line the inside and absorb heat at a fixed temperature until they have fully melted.

Where it is used
Medicines and vaccines
Temperature-controlled transport where no power is available.
Reagents and samples
Runs between laboratories, hospitals and clinics.
Blood products
Short-haul transport with PCM plates matched to the required range.
High-value chilled goods
Any payload that needs a clean metal interior.

Questions and answers
How does a passive box hold temperature?
PCM plates are conditioned in a freezer or fridge and placed in the box. They absorb heat at a fixed temperature while they melt, and the insulation slows the heat coming in.
Which temperature ranges are possible?
The range is set by the PCM plates. Tell us your target, for example 2–8 °C, and the duration you need.
Why a stainless steel liner?
It does not absorb liquids or odors and stands up to repeated disinfection.
Can you make other sizes?
Ask us. Tell us the payload dimensions and we will check what is possible.
