Next-Gen Liquid-Charged Heat Exchanger

BTMS MAX: Precision Cooling for Cylindrical Powerhouses

BTMS MAX is a flexible, tube-based liquid heat exchanger tailored for high-performance battery packs. It ensures optimal cell temperatures (20 - 40°C) through direct, full-surface contact — delivering superior cooling / heating efficiency that outperforms traditional aluminum designs by 9% in thermal power while being over 70% lighter.

Why BTMS MAX Outperforms the Competition

Permanent cell contact

Guaranteed for every cylindrical cell via flexible tubes that adapt to any shape change - delivering full-surface heat transfer with zero blind spots.

Adaptive design

Seamlessly scales across industries (automotive, aerospace, robotics) and diverse end-product lines - from EVs to energy storage systems, robots and custom battery packs.

Superior Efficiency

Exceptional heat transfer efficiency, streamlined low-waste manufacturing, and higher energy density with minimal losses - unlocking longer range and extended runtime.

Engineered in Czechia for global scale — trusted by innovators who can't afford downtime.
