The Universal CAB Batch Type Furnace<\/strong> provides high aluminum brazing<\/strong> quality for lower volume producers.\u00a0 It is designed to\u00a0braze the widest variety of heat exchangers<\/strong> in\u00a0a\u00a0horizontal or\u00a0vertical position depending on\u00a0the product design requirements. It operates on\u00a0a\u00a0part-time basis and produces the highest quality parts with standard or\u00a0vacuum purge options, respectively. The batch type furnace can be\u00a0brought up to\u00a0brazing temperature from ambient and conditioned to\u00a0a\u00a0proper atmosphere in\u00a0a\u00a0very short time. The batch system<\/strong> allows for variable heating and cooling rates, depending on\u00a0product requirements.<\/p>\n [\/et_pb_text][et_pb_tabs module_class=”red-tabs eco-tab3″ _builder_version=”4.23.1″ custom_css_main_element=”margin-top: 2rem;||margin-bottom: 2rem;” global_colors_info=”{}”][et_pb_tab title=”Overview” _builder_version=”4.23.1″ global_colors_info=”{}”]<\/p>\n Two basic batch models are available: Atmosphere purge and vacuum purge, each of which are available in\u00a0a\u00a0variety of configurations.<\/p>\n The commonly used two-chamber atmosphere batch system allows for variable heating and cooling rates, depending on\u00a0product requirements. One chamber provides purging and cooling in\u00a0the nitrogen atmosphere while the other chamber is the convection-heated brazing furnace. To\u00a0get the proper atmosphere parameters, several exchanges of the volume in\u00a0the entrance chamber is required in\u00a0the standard batch CAB unit.<\/p>\n The same level of an atmosphere can be reached by using a vacuum purging option saving dozens cubic meters of nitrogen per cycle. Two chamber vacuum purging units can also be upgraded later to three chambers unit for economically increasing the throughput.<\/p>\n Other options include: degreasing\/drying\/debinding oven, fluxer, transfer systems, final cooling, and computer controls.<\/p>\n [\/et_pb_tab][et_pb_tab title=”Benefits” _builder_version=”4.23.1″ global_colors_info=”{}”]<\/p>\n \/\u00a0<\/span>Highest flexibility<\/strong> \/<\/span> Short preparation time\u00a0<\/strong> \/<\/span> High brazing quality<\/strong> \/ <\/span>Space-saving<\/strong> \/<\/span> Lower cost<\/strong> \/ <\/span>Significantly lower nitrogen consumption<\/strong> \/ <\/span>More lustrous surface after brazing \/ <\/span>Higher brazing quality<\/strong> [\/et_pb_tab][et_pb_tab title=”R&D Single Chamber CAB Batch Furnace” _builder_version=”4.23.1″ global_colors_info=”{}”]<\/p>\n Single chamber furnaces with vacuum purging are also available for special applications, mostly dedicated for R&D laboratories, prototyping, and any initially low-volume production. This special design enables precise control of the heating and cooling speeds during the entire cycle. Atmosphere conditions like oxygen and\/or dewpoint can be\u00a0set at\u00a0defined levels. The single chamber batch-type furnace is an effective pilot furnace, capable of simulating a\u00a0wide range of brazing conditions and brazing process profiles scalable to\u00a0larger, continuous furnaces.<\/p>\n The single chamber CAB furnace has a\u00a0compact design with an internal recirculation fan and external cooling air blower. The packaged furnace system consists of the heating system, vacuum pumping system, nitrogen system, and atmosphere controls. The brazing cycle begins with vacuum purging of the stainless steel retort with N2 back purge, followed by\u00a0fast and uniform heating up to\u00a0brazing temperature. When the soak cycle is complete, the cooling cycle is initiated.<\/p>\n The advantage of a\u00a0vacuum purge batch furnace is that it is always ready for work at\u00a0room temperature and it is cold when the cycle is completed. No\u00a0pre-heating is required.<\/p>\n [\/et_pb_tab][et_pb_tab title=” ” _builder_version=”4.23.1″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n \/ <\/span><\/strong><\/span>Thermal afterburner to reduce VOC emissions for degreasers \/<\/span><\/strong> Electric heating systems instead of gas heating systems (including modification of current equipment) to reduce CO2 emissions [\/et_pb_tab][\/et_pb_tabs][et_pb_code admin_label=”Code” _builder_version=”4.23.1″ _module_preset=”default” global_module=”123774″ saved_tabs=”all” global_colors_info=”{}”] PREMIUM LIBRARY<\/span><\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”R&D en” module_class=”product_widget_wrap_rd” _builder_version=”4.23.1″ _module_preset=”default” text_orientation=”center” global_module=”167835″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n R&D<\/span><\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”AUTOMATYKA en” module_class=”product_widget_wrap_automation” _builder_version=”4.23.1″ _module_preset=”default” global_module=”167846″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n AUTOMATION<\/span><\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”SERVICE EN” module_class=”product_widget_wrap_service” _builder_version=”4.23.1″ _module_preset=”default” global_module=”167859″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n SERVICE<\/span><\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”SUPLEMENTALS EN” module_class=”product_widget_wrap_supleme” _builder_version=”4.23.1″ _module_preset=”default” global_module=”167809″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n SUPPLEMENTALS:<\/span><\/p>\n [\/et_pb_text][et_pb_text admin_label=”Product brochure” module_class=”suplementals_product_brochure suplementals_wrap” _builder_version=”4.23.1″ _module_preset=”default” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n Product brochure<\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”Product catalogue cab en” module_class=”suplementals_product_catalogue suplementals_wrap” _builder_version=”4.23.1″ _module_preset=”default” hover_enabled=”0″ global_module=”170306″ saved_tabs=”all” locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n Product catalogue<\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”Product infographic” module_class=”suplementals_product_infographic suplementals_wrap” _builder_version=”4.23.1″ _module_preset=”default” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]Product infographic<\/a>[\/et_pb_text][et_pb_text admin_label=”Product movie cab playlist en” module_class=”suplementals_product_movie suplementals_wrap” _builder_version=”4.23.1″ _module_preset=”default” global_module=”170307″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n Product video<\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”dnabook-en” module_class=”suplementals_product_dna suplementals_wrap” _builder_version=”4.23.1″ _module_preset=”default” global_module=”167873″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n DNA\/BOOK<\/a><\/p>\n [\/et_pb_text][et_pb_text admin_label=”ECO\/BOOK-en” module_class=”suplementals_product_eco suplementals_wrap” _builder_version=”4.23.1″ _module_preset=”default” global_module=”165507″ locked=”off” global_colors_info=”{}”]<\/p>\nMain benefits:<\/h2>\n
