Coval is expanding its range of intelligent vacuum pumps with the launch of new products: LEM+ and LEMAX+, more powerful versions of the LEM and LEMAX, vacuum pumps previously commercialized by Coval. The LEM+ reaches a flow rate of 125 to 385 NI/min and the LEMAX+ reaches a flow rate of 125 to 200 NI/min. The LEM+ is optimized in terms of energy savings for handling porous pieces with a rough surface, while the LEMAX+ is optimized in terms of energy savings for handling semi-airtight and airtight pieces. Each model is equipped with its own energy-saving technology: for the LEM+, ASR (Air Saving Regulator) technology regulates working pressure at 3.5 bar, whatever the pressure supplied by the compressed air network, ensuring energy savings of 40% on average. For the LEMAX+, once vacuum is created ASC (Air Saving Control) technology enables the piece to be held without any energy consumption. The result is energy savings of 90% on average. Finally, the automatic timed blow-off after each hold saves using one automaton output.
