NB 300/BOWAX with Gas-Fired

The chamber furnace of NB .. BOWAX series is suitable for Flash Fire processes in which the hot furnace is charged with raping castings. For a quick loading and unloading, the furnace is equipped with a pneumatic lift door, which is controlled via a footswitch. After charging, the wax liquefies in short time. The first part of the wax flows-out through the integrated pan directly into a catch basin under the furnace and is collected safely in a water tank. The remainder of the wax evaporates in the oven chamber and is burned safely in the downstream thermal afterburning. The resulting exhaust air is conducted via an exhaust chimney and a secondary customer side piping out of the hall. In the event of a flame failure of the burner or gas shortage takes place a process termination.
