Abstract (en)
[origin: EP2058521A1] The unit (1) has a single staged dry vacuum pump (2) e.g. single staged bilobed root pump, including a compression stage body (13) provided with gas inlet and outlet (15, 17). A heating unit has removable heating resistors (24, 29) arranged at the inlet and the outlet, respectively, in planes that are parallel between them and are perpendicular to directions (19, 21) of gas to be pumped to heat the body by thermal diffusion between the inlet and the outlet, where the resistors are in the form of circular arc shaped bands.
