Cell Block Presses

RECENT PROJECTS

50kN Cell Block Leak Tester

  • Ideal for leak testing single cells or stack of cells up to 200mm tall
  • Custom leak test tooling with specially-designed interfaces
  • Servo-press for precise pressure control and low maintenance
  • Laser sensor for top of cell/stack of cell detection.
  • High speed 80mm/sec operation, slows to slow speed just above the plates and then quickly compresses to kN setpoint with no-overshoot.
  • Accurate to ±0.050 kN
  • Repeatable to ±0.020 kN
  • Optional built in pressure interlock, press will not open with pressure detected in any circuit.
  • Adjustable back tilt from 0-20°.
