The robust construction of LCF industrial chamber furnaces makes them ideal for applications such as the heat treatment of steels and alloy, ceramics sintering and aerospace heat treatment.

The LCF industrial furnace range is often customised in order to precisely meet the user’s requirements. This range also provides a foundation upon which a wide range of custom modifications can be added. Typical examples of which are the more sophisticated control systems and data recording that is required for applications such as AMS 2750E heat treatment under Nadcap. Solutions are available to handle heavier loads or assist in loading and unloading the furnace, or larger chamber sizes than are offered in the standard range.

The KVT / KVZ vertical split tube furnaces have been designed for use with large work tubes or reactor vessels up to 200 mm outer diameter.

The furnace body is hinged and split into two along its length and is held closed with over-centre clamps providing easy access to reactors or work tube. These furnaces can be used for many applications such as heating reactors in pilot plant or the manufacture of plastic parts in the automotive industry.

The large diameter of the K range furnaces is perfect for heat treatment of wafers and fuel cells. Extended length work tubes of 200 mm diameter are possiblein quartz and APM.

Standard features

• 1200°C maximum operating temperature
• Single zone models fitted with Carbolite Gero 301 PID controller with single ramp to setpoint and process timer

• To suit work tubes or work pieces up to an outside diameter of 200 mm
• Heated length of 600 or 1200 mm
• Furnace splits into two halves to accommodate work tubes or samples fixed into a test rig
• Wire elements in high quality vacuum formed insulation ensure fast heat up, excellent temperature uniformity and short cool down times

Options (specify these at time of order)

• Over-temperature protection (recommended to protect valuable contents & for unattended operation)
• A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
• 300 mm diameter on request

The GPCMA modified atmosphere chamber furnaces are equipped with a metallic retort to provide a heated volume with a controlled atmosphere. They are floor-standing models with a smooth action hinged door arrangement.

Available with a range of maximum temperature from 1000 °C to 1150 °C dependent on the selected retort material. Retort working volumes range from 37 to 245 litres.

Oxygen levels can be reduced to 30 ppm depending on the application. Perfect for stress relieving additive manufactured components particularly those produced via DMLS. This range of furnaces can be optionally specified for compliance to AMS2750E Nadcap class 1 for aerospace applications.
