Hydro test products: ND1+1 - FRITZ EMDE - Mechanical and vacuum engineering

Pressure test:

  • Testing Unit to test fire extinguishers as well as cylinders up to max. 30 bar
  • max. diameter: 210 mm
  • max. admitted height: 730 mm
  • Two separate clamping positions, equipped with quick-adaptor. These are equipped with ascending pipes according to the size of the cylinder
  • Adaptation of the cylinder at the quick-adaptor; the cylinder is placed head down on the adaptor
  • Clamping of cylinder is effected pneumatically
  • Control of the complete procedure by SPS
  • Testing procedure is started manually by button, operation works automatically by SPS
  • During pressure raise the testing area is protected by a sliding door. Water filling comes out of the water tank through the pressure line directly into the pressure tank
  • Pressure build-up by compressed- air driven one piston pump (all parts getting in touch with water are made of special steel)
  • Pressure indication by sensor which is shown on a digital display
  • Disconnection at the preset pressure is automatically; indication of the present pressure at the display
  • Control of pressure after adjusted stop period is automatically; signaling when pressure test has been unsuccessful
  • In case of successful test, the cylinder is emptied automatically by compressed-air assistance. Water gets directly into the water tank
  • Pressure test is effected on each cylinder separately
  • Pressure test: Low-Pressure 0 – 30 bar
  • Pressure test is effected mutually
  • Fast emptying of the cylinders by blowing the water out by compressed air
  • Illumination of the unit

Optional available at extra charge:

  • Control system to memorize data by PC
  • Possibility to adjust data of cylinder by Keyboard
  • Indication and printing of pressure course by software program with display
