Wearers of PPE performing heavy work in hot and humid conditions are not only at risk of reduced concentration, productivity and safety. Heat stress can result in illness, injury or, in cases of heat stroke, even death if the symptoms are not treated early. Despite this, each year, more instances of heat-related illness occur globally among PPE wearers.

The UK’s 10 hottest years on record have all occurred since 2002. In 2003 there were 2,193 excess deaths across the UK between 4th – 13th August due to heat stress

Extreme temperature events in Europe are now 10 times more likely than they were in the 2000’s. By the 2040’s, severe heatwaves could occur every other year.*

How does KALIS Dry Cooling technology work?

Dry Cooling Technology uses an innovative two-part structure – storing water between a semi-permeable outer membrane and an impermeable inner layer. It cools the wearer by utilising energy from the water as it evaporates. This means that – in contrast to wet cooling systems whose lifecycles are shortened by humid conditions – our new system thrives in this environment and can last for one to three days after a single activation.
