The L170 service cart has been developed as entry-level model of the Mega Series for the gas handling on large gas compartments. Thanks to the state-of-the art control all functions run automatically and are displayed on a 10“ multi-touch screen. A new software with intuitive user navigation makes operation very easy and comfortable. This service cart can optionally be operated via smartphone, tablet or laptop. Precondition for the construction of this series which allows SF6 gas recovery down to < 1 mbar was emission-free gas handling. When using the totally gastight DILO couplings and connecting systems emissions will have no chance! Short gas recovery and evacuating times are obtained by using a coupling DN40. The L170 series is available with a second DN20 connecting coupling (as option) so that two work steps can be carried out simultaneously. Thus it is possible to evacuate air from a gas compartment while filling SF6 at the same time or recovering gas from another gas compartment. Multitasking in practice.
