Why choose the TunnelWatch?

Efficiency and effectiveness no doubt top your list for car wash tunnel control system must haves. The easier it is to operate the system, the better. That system earns extra points if employees can learn how to operate the system quickly. The less downtime, the better, of course, and scalability is a must. But the bottom line is customer experience.  

In other words, you’re looking for something better than the industry standard. TunnelWatch has you covered.

Lower Costs
TunnelWatch activates equipment onlywhen needed rather than cycling up early or remaining on after a vehicle passes. This reduces equipment wear and chemical and utility costs.

TunnelWatch Car Wash Tunnel Equipment Features

Quick Status Screen
TunnelWatch 5 powers the Quick Status Screen on DRB®'s Tunnel Control Station 2. It allows you to view conveyor speeds, queue and tunnel activity, alerts, warnings and other important information at-a-glance on the Tunnel Control Station ’s integrated PC touchscreen.  

  • Screen border changes color when a condition arises that needs your attention
  • Shows why a conveyor has stopped
  • Alerts you when simulated pulse or simulated enter has been activated
  • Displays easy-to-read override information on the main screen

Additional Features

Live Queue and Tunnel Status
Watch graphical representations of vehicles travelling through a virtual tunnel. When integrated with CarPics®, TunnelWatch displays the photos of each vehicle rather than graphical representations.

Vehicle Traits Feature
Easily adjust conveyor equipment for different vehicle sizes and external features for less equipment wear and tear and better vehicle coverage.

Live Invoke
Make changes to tunnel equipment configuration while cars are in the tunnel without interrupting wash services.

Device Saturation Guard
User-controlled configurations automatically cut off solutions like tire shine when enough chemical has already been applied to the device to handle the next vehicle.

Collision Avoidance
Supports two sensors located at the tunnel exit that detect if a vehicle pulls out early or if another vehicle is approaching too closely. Get further collision protection by adding NoPileups™.

Smooth SiteWatch® Interface
TunnelWatch can directly connect to the SiteWatch POS system without requiring an SRMB or serial cable.

Simulated Pulse and Enter Switches
Allows you to continue to wash cars when real switches fail. Simulated Pulse maintains the last known conveyor speed and allows the operator to adjust as needed. The Simulated Enter assumes the maximum length in lieu of the actual switch detecting the real vehicle length.  

Cloud Backup
Includes automatic off-site backups, a simple one-step recovery process and the ability to reload prior configurations.

Easy Updates
Updates are completed remotely.

Gain Even More Control of Your Tunnel Car Wash Equipment

Add the following products to further fine-tune your tunnel performance.

Uses sonar to profile vehicles to the inch and automatically identifies and adjusts for features like pickup truck beds and side mirrors without human intervention. This helps you minimize waste, reduce equipment wear and tear and deliver a better wash.

  • May reduce the number of relays so you can use them for future expansion or to control other equipment more precisely
  • Requires minimal wiring, saving you electrician fees and installation hassle
  • Can control an unlimited number of devices because the profile detected is built into the program for each car and doesn’t require wiring to individual devices
  • With “Simulated Sonar,” in the unlikely event the sonar detector fails, TunnelWatch will assume a standard truck profile and behave accordingly for all devices in the tunnel
