Products

• TP 1200 Touch Panel Control System: A 12 inch touch panel control system giving an overview of furnace status, built on an industrial standard Siemens PLC. A pre-program evacuates the furnace before heat treatment starts so that any errors are handled safely.
• TP 1900 Touch Panel Control System: A 19 inch touch panel control system for fully configured furnaces and for hydrogen work above 5 per cent. It runs on a Siemens F-PLC and its pre-program carries out a fully automated leakage test in overpressure and vacuum.
• Glove Box Furnace Systems: Customised glove box furnace systems in which a tube or chamber furnace is integrated with a glove box, so air sensitive samples can be loaded without exposure. Glove box size, air locks and glove count are built to the customer's requirement.
• Strand Line Furnaces: Continuous heat treatment furnaces through which one or more strands of material pass for hardening and tempering. The strand runs through Inconel or ceramic tubes, and individually controlled zones hold uniformity along long heated lengths.
• Carbon Fibre Heat Treatment Furnaces: Custom furnaces for carbon fibre research and production, covering the three stages of the process. Precursors are debound in a metal work tube, pre-sintered in a ceramic work tube, then finally sintered in a water cooled graphite heated vessel.
• Natural Convection Laboratory Oven PN: A bench mounted 300 deg C laboratory oven in which air circulates by natural convection. The slow airflow suits powders that would be disturbed by a fan and reduces the risk of cross contamination between samples, and the design allows use in an ISO 8 working area.
• Fan Convection Laboratory Oven PF: A range of four bench mounted 300 deg C laboratory ovens with fan convection. Forced air circulation gives better temperature uniformity and faster recovery after the door is opened than the natural convection PN models.
• High Temperature Laboratory Oven LHT: A range of three bench mounted high temperature laboratory ovens with a heavy duty convection fan. Each size is available with a maximum operating temperature of 400, 500 or 600 deg C and is suitable for continuous operation.

• Modified Atmosphere Chamber Furnace GPCMA: A floor standing chamber furnace fitted with a metallic retort to give a heated volume under controlled atmosphere. Oxygen can be reduced to 30 ppm depending on the application, which suits stress relieving of additively manufactured parts.
• Top Hat Furnace HB: A furnace with an automatically operated vertically moving hood, so the load can be reached from three sides. Bottom loading HB-BL versions keep the hood fixed and move the hearth instead, and preheated air fans can be fitted for debinding.
