Marcé Fire Fighting Technology, based in Centurion in the Gauteng Province of South Africa, is Southern Africa’s largest manufacturer of firefighting vehicles. They have produced hundreds of vehicles over the over 20 years the company has been in service, as well as offering other small equipment, vehicle refurbishments and assert management services.  Given the difficult and often dangerous nature of firefighting, Macré strives to provide 100% customer satisfaction, so their customers have one less thing to worry about.

Onboard Control Platform

One of these customers is the Namibia Airports Company; Macré manufactures all of their Aircraft Rescue and Firefighting (ARFF) vehicles.  These vehicles need an onboard control platform that can control both day to day operations and full pump and engine operations in a crisis situation.  The reliability of this control system was a top priority to ensure the safety of users in the field.

All-in-one PLCs with Integrated HMI Panels

Marcé Fire Fighting Technology installed a control solution using Unitronics all-in-one PLCs with integrated HMI panels.  These PLCs are installed in each truck’s cab, where the touchscreen HMI panel makes it easy for the driver or other personnel to access the system.  The operators can view the current foam and water levels, select or adjust the ratio of foam to water and turn the spray on and off as needed.  The PLC controls the pumps to release water and foam and monitors pressure levels.  It also controls peripheral features of the truck, such as the lights and sirens. Macré liked Unitronics PLCs because they were highly reliable and the large integrated HMIs make the control system easy to use, even in a high pressure situation.  Moreover, Unitronics all-in-one design simplifies the PLC programming and configuration.

Data Logging and Remote Access

Macré’s IT manager explains “At first I was hesitant in…having to go through the labor pains or making something new work and fit into what our clients demand from the vehicle.  I can say that after a day learning the PLC programming … I don’t regret making the decision in using Unitronics products as we take the technological step forward in firefighting applications.”  The ladder logic, HMI design and communications are all programmed in a single software environment and Unitronics offers a full suite of advanced utilities for data logging, remote access and more.  Unitronics industry leading technical support engineers were available every step of the product development and deployment to answer questions and solve problems.
