Batchmaster® Box Furnace
If you are looking for a box furnace or large oven, contact Surface Combustion today. Heat treaters worldwide know that Surface® furnaces provide greater value through an unmatched combination of reliability, repeatability and rugged performance. We will help you determine the optimum solution from our pre-engineered or custom designs for your process, product and material
The Batchmaster® Single-Chamber Large Oven Box Furnace is a flexible, economical, pre-engineered design that is easy to operate and maintain. The Batchmaster can be configured to meet numerous processes, product and material requirements and is available in many standard sizes and hearth loadings. Installation and start-up time are minimal as the furnace comes with a pre-mounted, pre-wired control cabinet and a maximum of three utility connections.
Surface has a long history of producing large oven furnaces dating back to our company’s founding in 1915 with over 700 installed worldwide. Surface large oven furnaces are used in every industry that uses heat treating for a wide range of components from small hand tool parts to large forgings, billets and castings.
The Batchmaster uses the latest technology in heating, energy efficiency and controls combined with Surface’s reputation for rugged furnace construction. The furnace casing is manufactured with heavy steel plate supported by structural steel shapes. The insulation package is balanced to be energy efficient, allow rapid temperature changes and ease of maintenance. The Batchmaster door is vertically lifted to allow front loading and uses Surface’s proprietary energy-saving tight-fitting door design. The furnace may be loaded with simply a fork truck or an advanced automated charging system. Multiple furnace hearth designs are available to support light or heavy workloads and enable automation.
With the Batchmaster, you may choose either recuperated direct-fired burners or electric elements for your heating system. Our direct-fired option uses rear-wall mounted medium velocity tempered air burners and our proprietary flue pipe design to enable a wide range of operating temperatures and excellent temperature uniformity. The oxygen content of the atmosphere can be controlled with our proprietary POCRecircTM system. Electrically heated Batchmasters have refractory mounted specialty alloy heating elements positioned based on the furnace size, required heating rate, and required temperature uniformity. For additional improvements in heating rate and temperature uniformity, proprietary roof mounted Surface VFTM fan units may be installed.
A Batchmaster can be designed to stand alone or be part of a new or existing furnace line. Surface provides a wide range of companion equipment, advanced controls and support services for single source responsibility. This allows you piece of mind that your installation will run smoothly, and your equipment will be taken care of for the long term.
The Batchmaster is meant for processing product in an atmosphere containing products of combustion (direct-fired) or air (electric). If you require a different atmosphere, and you would like a standard-rated, single-chamber design, Surface suggests our RTBTM single-chamber atmosphere box furnaces. Surface has also designed special removable retorts to operate within the Batchmaster furnace.
