Cooling tract provides flexible options

REHM THERMAL SYSTEMS VisionX range of cooling tract variants for reflow convection soldering can be precisely fine-tuned to suit any production process. The water-cooled standard solution comes with adjustable ventilation system, as well as additional options for large and high-mass boards, primarily a power cooling unit as an extended cooling tract or a bottom cooling system.
Product transforms the classic cooling tract into a two or four-layer system, depending on the facility. This design incorporates an active cooling process, water-cooled using heat exchangers following an efficient ‘closed loop’ system.  http://www.rehm-group.com
