Product Overview

Built for Demanding Fleet Environments

Enable controlled access to vehicle wash systems, gates, barriers, and other electrically triggered equipment — ensuring only authorised users can operate critical site infrastructure.

Fully compatible with Merridale fuel management systems or capable of operating independently, it provides a flexible solution for sites of all sizes.

The MX-GR uses secure key or driver identification to authorise access. Once validated, it sends an electrical pulse to activate the connected system — whether that’s a wash unit, gate, barrier, or other controlled equipment.

This ensures that only approved users can initiate operations, reducing misuse, improving site security, and protecting valuable assets.

Key Highlights

  • Restrict wash usage to authorised vehicles and drivers, preventing misuse and unnecessary costs.
  • Manage entry and exit points to depots, yards, and restricted areas with full tracking and control.
  • Control access to compressors, pumps, or other electrically triggered systems across your site.
  • Every event is logged and reported — supporting accountability, compliance, and operational insight.
  • Seamless system integration or flexible standalone operation.
  • Available as pedestal or wall-mounted to suit the needs of any fleet.
