A new controller that pays for itself
An end-of-life controller means a breakdown that can stop the factory overnight, and badly dosed batches that end up as rejects. PrefaPro tackles both.
- 10 to 22 months payback for a factory producing 3 million blocks a year
- ≈ €10,000 of lost revenue per day of breakdown for a factory of this size
- Concrete-related rejects cut by about 90%, measured at a customer site
Assumptions: block sold at €0.80 (80% materials, about 20 kg); 2.5% concrete-related rejects, reduced by 90% (customer case); annual maintenance included; 250 production days per year.

Frequently asked questions
Can PrefaPro replace the controller of a plant from another manufacturer?
Yes. PrefaPro takes the place of your current controller, whatever its brand, with no custom development. The assessment of your installation confirms this before any order.
Do I have to stop production during the replacement?
The upgrade is planned so you don’t have to shut everything down: installation, commissioning and training are carried out within a guaranteed lead time agreed with you in advance.
How does PrefaPro reduce rejects?
The probes measure sand moisture and the Hydronix doser adjusts the water based on previous batches. Weighing is corrected continuously. The concrete is more consistent, with less cement and fewer rejected products.
Does PrefaPro connect to my management software?
Delivery notes, weighings, stock levels and alarms are logged and can be sent to CBAO or Arcade software.
