Next-Gen Heat Exchanger

In a world where battery failures cost millions, our FlexPlate heat exchanger
keeps every cylindrical cell cooler, lasting longer and charging faster.

Up to 70% lighter
High thermal performance
Electrically non-conductive
Adaptive cell contact
Dielectric oil compatible
Expansion-ready

Validated in ISO-certified tests.

Solutions for Modules & Packs

BTMS for Battery Modules

Optimized FlexPlate layout for battery modules. Compact, lightweight and ready for integration into larger packs.

BTMS for Battery Packs

Full-pack thermal management with FlexPlate technology. Maximum performance and uniformity across the entire cylindrical cell array.

How FlexPlate Works

FlexPlate Technology

FlexPlate combines flexible polymer micro-tubes with an adaptive structure that maintains permanent, full-surface contact with every cylindrical cell — even during expansion and contraction. This design eliminates the need for any Thermal Interface Material.

• Only 0.1 mm barrier between coolant and cell → superior heat transfer
• Fits into gaps as small as 1.3 mm
• No pre-forming required
• High pressure and temperature resistance
• Chemically and mechanically robust
