DelCool™
A platform technology that pairs perpetual cooling with active humidity management — wherever heat and moisture need to be controlled.
DelCool™ extends Alexium's perpetual cooling platform with active humidity management. While it has made its biggest commercial impact in bedding, the underlying chemistry is broadly applicable — anywhere a surface, garment, or enclosure needs to stay cooler and drier than the air around it.
The science: deliquescence
DelCool™ takes its name from deliquescence — the natural phenomenon in which certain hygroscopic materials* pull water vapor directly out of the surrounding air and dissolve into their own absorbed moisture. As humidity rises around the sleeper, DelCool's chemistry actively captures that excess water, releases the latent heat of absorption away from the skin, and forms a stable salt* solution that keeps working long after a conventional PCM has fully melted. When conditions cool and dry, the process reverses and the system regenerates — ready for the next night. *Specific hygroscopic material and salt chemistry are proprietary to Alexium.
Why heat and humidity must be solved together
Temperature is only half the comfort story; trapped humidity is what makes a surface feel hot, clammy, and uncomfortable long before the air itself does. By coupling phase-change cooling with deliquescent humidity capture, DelCool™ attacks both variables at the same time — maintaining a drier, cooler microclimate for the full duration of use, not just the first hour.
What DelCool delivers
- Continuous cooling sensation across extended-duration use
- Active moisture buffering for a drier contact surface
- Drop-in compatibility with standard textile and foam production
- Regenerates as conditions cool and dry — no single-use chemistry
- Pairs with AlexiCool® and Eclipsys® for layered thermal performance
Where the technology applies
- Bedding and mattress systems — pillows, toppers, covers, quilted panels
- Performance apparel and footwear — base layers, linings, insoles
- Personal protective equipment — helmets, vests, gloves, tactical gear
- Medical and patient-comfort textiles — supports, wraps, seating
- Transportation and seating — automotive, aerospace, office
- Packaging and enclosures where humidity control extends product life
Industry spotlight: bedding
Bedding has been DelCool™'s first major commercial proving ground. Finished mattress product built on the technology has reached the retail floor — including placement with a major national department store — giving the chemistry real-world validation beyond the lab bench and showing how deliquescent cooling translates into a difference shoppers can feel.
For brands chasing the next benchmark
DelCool™ is the chemistry to specify when you need to outperform competitors on both temperature and humidity — the two variables end users actually feel. Talk to us about adapting the platform to your application, format, and production process.
