Wöhler DP 700 Leakage Tester

Leakage Test on ventilation systems and components

Ever-increasing demands are being placed on the energy efficiency of VAC systems. In that respect the leak-tightness of ductwork has a particularly important role to play. This aspect holds the greatest potential for saving energy, if it is possible to adapt the air flow to actual requirements in conjunction with low leakage rates. In this respect, low device-and ductwork leakages will in future need to be taken into consideration a great deal more. Consequently, corresponding measurements will gain in importance.

Functionality / Advantages

  • Leakage test according to DIN EN 12599 – to hand over air conditioning and ventilation systems
  • Leakage test according to DIN EN 14134 – installation checks of residential ventilation systems
  • Quality assurance in the production and assembly of air ducts and components as well as equipment
  • Measurement of leakage class according to DIN EN 13779 of ventilation ductwork systems and components in accordance with the standards DIN EN 1507, DIN EN 12237, DIN EN 13403 and DIN EN 13180
  • Fulfills the high accuracy requirements specified in DIN EN 1751 and DIN EN 15727 for measurements on individual components (± 0.0009 l/s)
  • Additional adapters for air flow rates < 0.3 l/s assure high levels of accuracy
  • Also suitable for leakage tests outside of VAC-systems
  • Easy to operate with operator guidance or expert mode
  • Practical set suitable for a wide range of applications

Wide range of applications

  • Leakage tests in large air leakage ranges: From individual components through to complete systems consisting of several 100 m²
  • Leakage tests on air-conditioning units, switchgear cabinets, climatic test cabinets, heat exchangers, cabinets for clean room technology and other housings
  • Leakage testing of rooms
  • On-site and laboratory measurements on structural components (e.g. OSB boards, windows)
  • Can be integrated into the final inspection routine of series production runs including optional program remote control, (controlled from a PC via USB port)
  • Suitable for tests of lower output performance (40 l/s), 110 V, 60 Hz

Data management

  • Store up to 100 measurements
  • Data stored permanently in the instrument
  • Customer and data management with the Wöhler DC Series PC software (optional accessory)
  • Data transmissions via USB connection
  • Print out measurement results including graphic chart on a printer (optional accessory)
