Hohenstein laboratory testing demonstrates up to 60% greater evaporative cooling capability versus comparable products
We’re pleased to share the results of new independent laboratory testing carried out by the globally recognised Hohenstein Institute, validating the performance of our ActiKewl® cooling technology powered by SAF™.
The testing, commissioned in partnership with Technical Absorbents, assessed the performance of multiple evaporative cooling garments under controlled hot-climate conditions, providing a robust, real-world benchmark for cooling performance.
Leader in sustained cooling performance
The Hohenstein protocol evaluated evaporative cooling performance under 32°C and 70% relative humidity, conditions specifically designed to challenge cooling materials and simulate demanding working environments.
A heated plate system was used to replicate body heat, with the electrical power required to maintain temperature providing a direct measure of cooling performance. In short, the higher the power required, the greater the cooling effect delivered by the material.
Across the full four-hour test period, the ActiKewl® cooling core (Gen 2 SAF™) delivered the strongest sustained evaporative cooling performance of all materials tested. The clear leader in sustained cooling performance.
Analysis from the SAF technical team further highlighted that:
ActiKewl® powered by SAF™ maintained the highest cooling output throughout the test window.
ActiKewl® powered by SAF™ delivered an average increase of approximately 60% in evaporative cooling capability compared to the nearest comparable material.
ActiKewl® powered by SAF™ demonstrated superior water absorption capacity (over 320g), enabling a larger evaporative reservoir to fuel the cooling performance.
ActiKewl® powered by SAF™ maintained a strong cooling performance over time, while other products showed rapid decline due to early drying
This combination of high water uptake and controlled evaporation is fundamental to sustained cooling performance, a relationship clearly illustrated in the test data.
Greater absorption directly translates to longer-lasting cooling performance, a critical requirement for teams and workers operating in high heat environments.
These results further strengthen the position of ActiKewl® as a next-generation climate adaptation technology, supporting organisations looking to protect worker comfort, safety and productivity in increasingly challenging thermal environments.
