jacket drum heater
The HM 20 is a jacket heater to heat segments of 200 litre DIN barrels. Both the inner and the outer jacket of the barrel jacket heater are manufactured from aluminium, which ensures maximum protection of the electrical components against mechanical damage.
A hinge with adjustable turnbuckle that divides the heating surface into two semi-shells permits convenient installation without having to bend the heating element; the barrel can be completely heated by using three sleeves.
The integrated thermal insulation increases efficiency and reduces the temperature of the touchable surfaces. The heating surface temperature can be set on the attached aluminium housing using a mechanical thermostat in the range 30 – 110°C. A 120°C thermoswitch is also incorporated in each semi-shell, as well as a 140°C thermal fuse as protection against overheating.
