    The OmniMax platform offers a combination of industry proven technologies in an easy to use, reliable and efficient reflow system for high-end production requirements. From lead-free to hybrid processing, the OmniMax 10 zone oven delivers high performance thermal processing. The OmniMax sets the standard in innovative technologies that save on lowest power and nitrogen consumption rates.

    • Uses a dual IsoThermal chamber approach that produces ∆T’s less than ± 2°C within 7 and 10 zone ovens (air or nitrogen)
    • Standard conveyor system supports a 20” (508 mm) process width
    • 10 zone process capability and control
    • Nitrogen replaces oxygen and provides greater profile flexibility and widens the process window
    • Prevents oxidation of solderable surfaces (promotes wetting) and of the molten solder, allowing for reduction of void levels
    • Stronger solder joints and shiny finish
  • The most powerful and Advanced Cleaner in the market.

    Aqua Klean Systems introduces the Typhoon T-8 Chemistry Zero-Discharge Cleaner, a new way to clean RMA, No-Clean, and Water Soluble (OA) fluxes. The T-8 incorporates an adjustable chemical injection pump to assist in keeping chemical wash concentration consistent.
