Customer Benefits
1. Extended battery lifetime
Precisely controlled cooling keeps the battery temperature within the optimal range, which:
-
reduces thermal stress
-
slows the loss of battery capacity
-
reduces maintenance frequency
2. Improved system safety
Overheating is one of the most significant risks to battery systems. The system helps to prevent:
-
temperature peaks
-
uneven thermal loads
-
premature component failure
3. Designed for electric vehicles and equipment
Thanks to its 400 VAC operating voltage, the system can also be installed as a liquid cooler for stationary machinery.
4. Industrial solution, not a consumer product
The solution is designed to:
-
continuous operation
-
for demanding environments
-
designed for long service life
