Controlled Atmosphere Aluminium Brazing (CAAB®) Furnace

AFC-Holcroft designed (Controlled Atmosphere Aluminium Brazing) CAAB® provides the most advanced and state-of-the-art technological edge for processing aluminium heat exchangers such as radiators, heater cores, condensers, evaporators, charge air and oil coolers. The combined experience of AFC-Holcroft’s Therm Alliance & Holcroft Divisions and the strategic alliance with HIGHTEMP translates into immense advantages in terms of the ability to supplying the latest in non-corrosive flux brazing technology to the aluminum heat exchange market.

AFC-HOLCROFT has redesigned the conventional CAAB® furnaces and the patented New Design CAAB® offers significant overall energy savings in normal production, with the component finish and quality as good –or better – than conventional CAAB® processing technology.

The New Design CAAB® offers the following features

  • No muffle
    - Easy maintenance, less downtime
    - No replacement cost
    - No flux build up below the belt, longer belt life
    - Lower ramp up time to operating temperature
  • Belt inside
    - Substantial savings in power
  • Radiant heaters
    - Easy maintenance/replacement, minimum downtime

Hightemp has built and installed the 1st New Design CAAB® furnace, which is in operation for more than a year now, and the comparative studies between the conventional & New Design CAAB® have shown overall energy savings up to 40%
