25 years in the making

A new standard in cold chain cooling

HydroPure™.
Water,
Not Gel.

HydroPure delivers gel-matching thermal performance, visible freeze assurance and a cleaner EPR position, giving modern cold chains the confidence to perform without compromise.

Engineered. Evidenced. EPR-ready.

Three things cold chain managers need to know.

Performance
48hr lab-matched against gel
Matched performance across 48-hour laboratory thermocouple testing. Full data shared with every launch programme member the moment they join.
EPR compliance
~1/2 a penny vs 14.5p
Indicative EPR fees per 500g pack, water vs gel. Designed so only the thin recyclable film is chargeable. Less than half a penny per pack.
Pack-out confidence
Assurance you can see. No guessing at pack-out.
The cracked-ice design and key messaging turns pure white when frozen to the core. Engineered-in confidence at every pack-out.

The Hydropac story

We don't just make ice packs.
We look after cold chains.

For 25 years, Hydropac has designed, tested and manufactured cooling technology in the UK - on machines we built ourselves, validated in our own laboratory.

We work alongside food, meal kit, pet food and pharmaceutical brands as cold chain partners: auditing, optimising and engineering pack-outs that protect product integrity from freezer to front door.

HydroPure is that expertise, sealed in a pack.

Common questions

Everything you need to know before you decide.

Joining commits you to nothing. These are the questions we hear most before people reserve their place.

So why is gel a problem?
Gel creates a poor end-of-life story. It can be messy, confusing to dispose of and harder to defend from a sustainability perspective.
Does water really perform as well as gel?
Yes. Water is the thermal engine inside most gel packs anyway. In 48-hour laboratory testing, HydroPure matched gel degree for degree - and the full data is yours the moment you join the programme.
Can gel go down the sink?
It shouldn't. Gel can swell and accumulate in pipework, increasing the risk of sink and drain blockages - not to mention ending up in waterways.
Is gel a forever material?
Gel-based fills create persistent polymer waste. HydroPure removes the polymer fill and uses water instead.
Why is the pack black?
By design. Absorbing heat is exactly what an ice pack is engineered to do - and the dark pack is what makes the pure white freeze signal unmistakable at pack-out.
Why does the pack have a cracked-ice design?
It's functional, not just decorative. HydroPure's transparent white design turns solid white when frozen - giving you an unmistakable visual signal at every pack-out.
How does HydroPure reduce our EPR liability?
Gel fill is chargeable material under EPR; water isn't. HydroPure is engineered so only its thin recyclable film counts - the same cooling function, at a fraction of the reportable weight.
Will it work in our pack-out?
That's precisely what your priority samples are for. Our specialists will work with you to validate HydroPure in your own configuration - box sizes, transit times, destination temperatures. That's how we've built cold chains for 25 years.
When does it launch - and what does joining commit us to?
HydroPure launches soon, and launch programme members hear first. Joining commits you to nothing - it simply reserves your sample allocation, founding-customer pricing and the laboratory data pack.
