The ERCU Electric Remote Control Unit is required when the operator is working at a distance greater than 40 m from the blast machine. The pneumatically-operated remote system has a response time that is too long for distances over 40m. At such long distances, a significant amount of time is needed for the air signal to reach the RCV valve.
Application
The ERCU Electric Remote Control Unit sends an electric signal from the DMH handle on the blast vessel. The ERCU control box then sends a signal of air to the RCV valve, instructing it to open or close. The ERCU control box is mounted directly on the blast vessel and has no time delay in sending the signal. Electric remote controls are also used in cold environments since pneumatic systems may freeze due to condensation that builds up within the lines.
Standard delivery
ERCU switch cabinet for mounting on BlastRazor sandblasting machine, DMH-E electrical remote control handle with cable with waterproof connector, 20m extension cable with connectors, 12 VDC transformer.
