usage. Heating elements must be used when the temperature limit for the relevant lubrication variant is undershot.The selection criteria for oil, lubrication and heating are shown below. Heating for vertical gear units on request. Horizontal mounting position, sizes 3, 5, 7, 9, 1, 1, 1, 1, 1, 1, 1 Horizontal mounting position, sizes 2, 4, 6, 8, 1, 1 Horizontal mounting position, sizes 1, 2, 2, 2 Heating elements are only permitted in combination with oil temperature monitoring. An electrical oil level monitoring system (available on request) is additionally required for heating elements of ATEX design. Depending on the type and size, up to 4 heating elements can be installed in the gear unit.Labyrinth seals are not permitted to be used with heating elements.
