CAB Brazing Systems for HVAC Aluminum Condensers and Evaporators

Switching from copper to aluminum?  Many manufacturers are switching from copper to aluminum condenser coils to meet new efficiency standards and reduce material costs.  SECO/WARWICK offers two Controlled Atmosphere Brazing (CAB) Systems for efficient production of aluminum condensers and evaporators:

High Volume Production - Radiation CAB Furnaces are an ideal method for brazing similar size products in a continuous flow environment. If you intend to produce a single or only a few variations of that product, a radiation furnace system makes sense.  A typical installation will process 50-100 condensers/ Hr.  The furnace is designed to use a stainless steel muffle to contain the nitrogen atmosphere and provide uniform heating of the products. The heat input into the furnace chamber is proportionally controlled through electric heating elements or natural gas fired burners to heat the muffle which in turn heats the products.

Batch Production - The Active Only® Semi-Continuous CAB Aluminum Brazing Furnace system is an indexing furnace designed to meet the needs of aftermarket manufactures or companies that have a wide variety of production needs from day to day. The furnace is designed to braze 4-8 condensers per hour on a semi-continuous basis.  The unique feature of the patented convection muffle arrangement is the placement of our braze cycle time control thermocouples. These thermocouples are the heart of this "intelligent" system and the indexing cycle when loading the furnace intermittently. This feature allows loading of the furnace load areas with products that have different masses, one right after another, without adjusting the furnace parameters. The heat exchanger alloys must stay the same but the mass of the cores may change from load area to load area.  

SECO/WARWICK is an expert in CAB Brazing technology with over 200 systems installed worldwide serving automotive and HVAC customers manufacturing  radiators, condensers, oil coolers, evaporators, heaters and charge air coolers.  SECO/WARWICK can provide the complete manufacturing cell complete with cleaning equipment, fluxers, drying ovens, cooling and atmosphere systems. Visit booth 2943 at the AHR exhibit January 26-28, 2009 at McCormick Place in Chicago to talk to our CAB team process specialists.
