CAB Electric Aluminium Radiator Brazing Furnace 1200 - 220 - 12000MM with Gas
The aluminium radiator brazing furnace is used to braze aluminum heat exchangers such as radiators, intercoolers, evaporators,
and heater radiator under protective nitrogen atmosphere. The flux used is NOCOLOK flux.
1) The CAB aluminum radiator brazing furnace adopts high performance porcelain fiber cotton material for heat preservation purpose.
The furnace is able to rise to 630℃ from the ambient temperature in around 2 hours.
2) The muffle of the brazing oven is once-formed by the large size bending machine, and is made from Sweden 316L steel plate and
304 steel plate. 10M muffle is formed by one-time bending, and only there is one v-slot at the bottom of the muffle. The one-time
forming muffle could reduce the misshapening effect at welding and also deformation at the heating process.
3) The zones of the furnace are divided based on upper, lower, rear and back area. The heating power is adjusted through PID
regulator so that the furnace could achieve an ideal temperature uniformity of ±1℃. The brazing area could achieve a temperature
uniformity of ±2℃ so that it could meet the brazing requirements.
4) The temperature controller has the PID regulation function to achieve a smooth temperature rise. Also the temperature controller
has the over-temperature alarm. The mesh belt is steplessly regulated through the inverter. The driving mechanism is started up in
the acceleration manner, and stopped in the deceleration manner to reduce the tension of the mesh belt.
5) the aluminum radiator brazing furnace (or called as CAB furnace) has a complete control system integrating intelligent control,
alarm and protection system. The real-time temperature recording function provide the process data of different products.
6) The area of the fluxing chamber which contacts the flux is made of stainless steel material. The two side walls of the fluxing
chamber are both set with an observation window to observe the fluxing performance. The fluxing nozzles have a 90º fan-shape
spraying to prevent nozzle blockage. There is a filtering net for recycling the flux to prevent damage to the fluxing pump.
7) The dry air cooling room is set with a slag cleaning chamber. There is a side door of the slag cleaning chamber for allowing
the worker to clean the flux slags. In comparison to the traditional water cooling chamber, the dry cooling room don’t have the risk
of corrosion because of water and deformation of the chamber because of cold and heat. There is no need for cooling water.
8) power at temperature rising stage: 100%; power at the brazing stage: ≤60%

Drying oven technical parameters
Function: the parts are well dried by the drying oven, and the dried parts are an important precondition of a high quality brazing process. The drying oven is an important parts of the aluminum radiator brazing furnace. The drying oven works with gas so as to save operational cost for the overall CAB brazing furnace line.
