Roller/Disc Heaters

Elmatic manufactures a range of quality disc and roller heaters which are be used for a number of applications. These heaters are mainly used for heat sealing in rollers on production line packaging machinery.

Designs

These roller and disc heaters are available and manufactured in aluminium, mild steel or stainless steel turned shells with a 5mm square section heater formed to a coil and fitted into the roller or disc. Each heater provides an alternative to a standard cast aluminium heater.

The advantages of our disc and roller heaters:-

• There is more heater length which reduces the watts density of the element allowing a longer life.
• Because the element design is that the element is fitted to the inner side of the outside edge, the heat is directed on the surface to be heated and not absorbed into the casting.
• Because there is not a casting process, the elements do not get damp during the machining process when being turned. This sometimes causes the element to absorb moisture in the magnesium oxide which gives low IR values.
• The availability of the square section heater is normally two weeks compared to the long delivery of a cast in unit reducing supply problems in case of a breakdown.

Working Temperatures

Our aluminium maximum working temperature is 300 deg C, watt density of 25w SQ inches (4w SQ cm). Also, our mild steel and stainless steel maximum working temperature is 600 deg C, watt density of 35w SQ inches (5.5w SQ cm).
