A robust range of laboratory furnaces, providing an excellent level of versatility without compromising quality, safety or reliability. All units in the ECF range have a maximum operating temperature of 1200°C. Heating is provided by two side-wall elements manufactured from high temperature resistance wire spirals embedded into cast refractory slabs. An exhaust chimney is fitted as standard. The insulated door opens upwards and outwards keeping the hot face insulation away from the operator. A door switch isolates power from the heating elements whenever the door is opened for maximum operator safety. The use of double skin construction allows natural air convection to maintain a cool outer case.
