The future goes into series production

Witzenmann already supplies first products today for series production: besides gas discharge lines for vehicle batteries, these are hose assemblies for hydrogen applications.
Innovative solutions for battery cases as well as the thermal management of electrical motors and batteries are in the conceptual design and development.

Applications for hydrogen in the low pressure range

Areas of Application

  • Fuel cell, medium and low pressure range

Technical characteristics

  • customer-specific certified stainless steels
  • extreme safety: designed for pressures of 10-20 bar; burst pressure testing over 500 bar
  • 100% helium leak-tested components
  • customer-specific weld certificates and specific certificates of approval of welding power
Battery Degassing Pipes Image Text

Battery gas discharge lines

Gas discharge lines are used when the batteries must be degassed within 5 seconds. In the process, temperatures of up to 700 °C occur.

  • suitable for 48-volt electrical power supply of vehicles and for high-voltage batteries of hybrid vehicles
  • technically gas-tight
