Remote control for dry pumps

This remote control package for VRC dry pumps gives the operator complete control of all parameters of pumps located up to 300 feet away. From the 14 ? 8.75-in. (356 ? 222-mm) panel, the operator can control power on/off, soft start, pumping speed, vacuum level, and gas ballast flow. The values of all these parameters are displayed on the panel, and outputs are available for process logging. The system is available for operation from almost any power line: 220, 240, 300, 460, 1 or 3 phase, and 50 or 60 Hz.
