| These furnaces are designed for light to medium duty applications where rapid thermal response is a primary requirement. Powerful, free radiating coiled wire elements are held firmly in the sides and roof of the chamber, which is constructed from rigedised low thermal mass insulation. A hard, dust-free, ceramic hearth provides a robust base for the furnace charge. This combination of high power and low thermal mass gives a heat up time from ambient to 1100°C is as little as 10 minutes, whilst rapid cooling can be induced by opening the furnace door during cool down. Other performance criteria are not compromised, with temperature uniformity, efficiency and control precision remaining excellent. Chamber sizes are 5, 13 and 23 litres with maximum temperatures of 1100°C and 1200°C. |
