Engineered
against
condensation.
A bidirectional humidity-control fiber that keeps sealed electronics dry — from EV battery packs to wind nacelles, solar inverters and 5G cabinets.
Every temperature swing puts water inside the enclosure.
Air cools to its dew point and moisture condenses on the coldest surface — the one your electronics sit on. Sealing tighter does not stop it.
-
Short circuits & leakage
Condensate bridges tracks inside the cavity and takes the board with it.
-
Blinded optics & sensors
A fogged lens suspends camera, lidar and driver-assistance functions.
-
Corrosion & early scrap
Metal oxidises, insulation degrades, thermal paths lose efficiency.
It absorbs. Then it gives the moisture back.
A 2-way humidity-control fibre core inside a microporous breathable film — it breathes with the cavity instead of filling up and failing.
-
Absorbs when the air is wet
Over 100 % of its own weight in 24 hours at 40 °C / RH 95 % — with no seepage.
-
Releases when the air dries
A desiccant fills up and quits. This fibre swings both ways, indefinitely.

Everything else we protect — grid, wind, solar, telecom, drones — sits inside the envelope a car already demands.
Eight cavities in a single vehicle.
Peel the liner, press it to any clean inner surface, close the housing. Nothing to wire, nothing to service.

- Charging port assembly
- Module & ECU enclosures
Eight industries, one failure mode.
Anywhere a sealed cavity meets a day–night temperature swing, condensation forms. The same pack solves it.
EV & e-mobility

Solar PV
String inverters, combiner boxes and junction boxes in the field.
Wind power
Nacelle electronics, converters and tower control cabinets.
5G & telecom
Base stations, remote radio units and outdoor equipment cabinets.
Drones & optics
Gimbal camera modules and lens cavities that fog on descent.
