New water-based coating manufacturing and filling plant: Process optimization at EUROTEX

EUROTEX: Manufacturing and marketing of industrial and decorative paints, and waterproofing products

EUROTEX began its business activity in the early 1980s as a specialized paint store in Mairena del Alcor, Seville. In 1987, aimed at gaining greater control over its production processes, the company started manufacturing the products it sold and established its factory and headquarters in El Viso del Alcor.

Currently, EUROTEX manufactures and markets a wide range of products, including industrial and decorative paints, primers, sealers, and waterproofing materials.

What product does the plant manufacture?

The project was focused on the manufacture of water-based paints and other water-based products.

The process is carried out in two tanks, where the dispersion and finishing stages of the formulation take place. The product then passes through a pumping and filtration system before filling.

The Challenge: Design and integrate a new water-based coating production unit

EUROTEX needed to install a new production unit for water-based products, consisting of a Dispermix VF-132-E high-speed disperser, two DE-7200 tanks, an MF-16 pumping and filtration unit, and a FLASH-21 volumetric filling machine.

The project presented three main constraints:

  • Tight Delivery Schedule: The installation had to be operational prior to the start of the production campaign, requiring a particularly demanding delivery schedule.
  • Limited Available Space: The new unit had to be integrated into an area with space and height restrictions. O+B designed a dedicated platform to accommodate the manufacturing equipment, taking into account the existing access points, its connection to an existing platform, and pallet access through safety gates.
  • Integration with third-party systems: The dispersion equipment had to be integrated with the solid and liquid feeding systems supplied by another vendor, requiring coordination among the different parties involved.

Oliver+Batlle’s Solution: A coating manufacturing unit tailored to space and process needs

Industrial machinery supplied for the production process

To meet the project requirements, O+B supplied the following equipment:

  • Industrial disperser: One Dispermix VF-132-E, equipped with a motorized crown for automatic head rotation, a telescopic cover with blade access port, an HDM Ø675 mm dispersion blade, and a bag support tray.
  • Process tanks: Two DE-7200 tanks to be installed on the platform, configured with a loading manhole and the necessary connections for powder and liquid addition, as well as dust extraction.
  • Pumping and filtration system: One MF-16 pneumatic pumping and filtering unit, designed for pumping and filtering the product manufactured in the DE-7200 tanks prior to filling.
  • Automatic filling line: One FLASH-21 volumetric filling machine, featuring a TA-100-HD hygienic hopper, NE-20 electronic level sensor, AV-20 valve with actuator, SLT-20 cleaning system, and DT-350 lid dispenser.

Plant layout engineering, assembly, and commissioning

In addition to supplying the equipment, O+B developed the plant layout engineering for the various elements located both above and below the platform: disperser, DE-7200 tanks, pumping unit, and automatic volumetric filling machine.

To accurately define the equipment layout, site measurements were taken beforehand, and construction drawings for the manufacturing platform were prepared and agreed upon with the client.

The platform was designed and engineered by O+B and manufactured and installed by a third party.

Mechanical assembly of the equipment was carried out by an O+B technician. Moving the disperser and tanks into position posed an additional challenge due to the limited space and height available, requiring close coordination with the crane contractor appointed by EUROTEX.

Electrical and pneumatic installation works were carried out by the client and subsequently supervised by an O+B technician.

Finally, O+B carried out the plant commissioning, starting up and adjusting the machines for normal operation.

Project Results

The new manufacturing unit enables EUROTEX to produce water-based coatings and meet customer demands in terms of both quality and turnaround times.

One of the main operational advantages of this configuration is the ability to stagger production and filling between the two tanks: while a batch is being filled from one tank, production of another batch can begin in the second tank.

This increased operational flexibility substantially enhances the plant’s overall production capacity.

How to Increase Paint Production Capacity in Confined Spaces: The Alliance Maestria Case Study

Space and headroom constraints are among the biggest challenges paint manufacturers face when trying to scale up production. When conventional silos or hoppers simply won’t fit, manufacturers need highly customized engineering solutions that can boost output without touching the building structure. In this success story, we explore how Oliver + Batlle optimized solids feeding and pneumatic conveying for manufacturer Alliance Maestria, eliminating production bottlenecks and quadrupling capacity within a severely restricted vertical space.

Alliance Maestria: Innovation in Decorative Paint Manufacturing

Alliance Maestria is an independent paint manufacturer headquartered in France, specializing in the development and production of coatings for a wide range of industrial applications. Their portfolio spans decorative solutions, flooring systems, anti-corrosion coatings, and road marking products, all formulated to meet varying regulatory and performance requirements.

For this particular project, the scope centered on optimizing the manufacturing processes for water-based decorative paints.

The product being manufactured is water-based decorative paint,a product where precise control over process conditions is critical to ensuring stability, consistency, and final quality.

The Challenge: Maximizing Solids Discharge in a Constrained Vertical Space

The primary technical constraint was the limited headroom in the dispersion area, which ruled out the use of conventional large-volume solids discharge hoppers.

This meant rethinking the entire raw material feeding system from scratch, finding a compact vertical solution that wouldn’t compromise process performance.

Alongside this, production requirements demanded high discharge flow rates in line with contractually agreed targets:

  • Carbonates: 15–18 t/h 
  • Titanium dioxide (TiO2): 10–12 t/h 

The technical challenge was therefore to engineer a dosing system that could perform within highly restricted spatial conditions, matching or exceeding the feed rates of conventional hoppers while delivering continuous, stable, and controlled solids discharge.

The Oliver + Batlle Solution: Integrated Automation and Pneumatic Conveying

Oliver + Batlle designed and implemented a comprehensive engineering solution aimed at making the most of the available space while fully meeting production requirements. The solution brings together solids handling, liquid dosing, dispersion, and packaging systems — all integrated under a single framework of advanced automation.

High-Efficiency Cyclonic Hopper System

Two cyclonic hoppers (SH-01 and SH-02) were installed at the highest available elevation, making full use of the vertical space. These hoppers deliver continuous, controlled solids discharge directly onto the dispersers:

The cyclonic geometry promotes the flow of cohesive materials, minimizing bridging and caking risks while sustaining continuous, high-rate discharge in space-constrained conditions.

Closed-Loop Pneumatic Conveying (Loop System) 

Solids transfer relies on dilute-phase pneumatic conveying in a closed-loop configuration, moving material from 14 m³ floor-level storage hoppers (WH-01 and WH-02) up to the cyclonic hoppers.

This design delivers:

  • Zero dust emissions: the system is fully enclosed 
  • Improved safety and housekeeping conditions 
  • Continuous, stable feed to the dispersers

Precise Liquid Additive and Emulsion Dosing

A dedicated system was put in place to handle liquid additives and emulsions, built around 250 L weighing hoppers and automatic distribution manifolds.

This system enables:

  • Precise, repeatable dosing of critical components 
  • Flexible feeding to both dispersers and finishing tanks 
  • Full integration into the process control logic

100% Automated Finishing and Packaging Lines

The installation is rounded out by a system for fully automated product finishing and conditioning:

Finishing tanks:

  • 4 units of 16,000 L 
  • 2 units of 11,000 L 

Fitted with high-precision Mettler Toledo weighing systems and CIP cleaning via rotary spray heads.

Packaging lines:
Two automatic volumetric filling lines, Flash 21, designed for precision, repeatability, and high production throughput.

Operational and Safety Improvements

In a subsequent project phase, further upgrades were introduced to boost system reliability and working conditions:

  • Replacement of vibration-based systems with Airsweep technology to improve solids discharge in large-volume hoppers 
  • Automation of packaging line cleaning cycles using dedicated Siemens S7-1200 PLCs 
  • Installation of a Big-Bag handling system with a 2,000 kg hoist, improving ergonomics and reducing operational hazards

Together, these improvements eliminated the constraints of the previous system and established a robust operational foundation capable of meeting , and exceeding, the flow rate and productivity targets defined in the project.

Arc-En-Ciel Project Results: Greater Profitability and a Cleaner Plant

The implementation of the Arc-En-Ciel project has delivered a significant step forward in operational performance, particularly in terms of conveying capacity, cycle time reduction, and overall process efficiency.

Significant Increase in Conveying Flow Rates

The closed-loop pneumatic conveying system, combined with the cyclonic hoppers, has not only met but surpassed the contractual targets:

  • Calcium carbonate (CaCO3): hasta 20 t/h (objetivo: 18 t/h) 
  • Titanium dioxide (TiO2): hasta 17 t/h (objetivo: 12 t/h) 
  • Talc: up to 11 t/h 

These figures represent a substantial improvement over the previous system, eliminating the bottlenecks caused by poor solid-air separation that had been restricting flow rates and causing material losses.

Reduced Cycle Times and Higher Productivity

The higher feed rates have made it possible to quadruple solids feeding capacity to the dispersion stage, significantly cutting batch loading times and, by extension, total process time.

The knock-on effects are tangible:

  • Higher plant throughput 
  • Less idle time in the dispersion stage 
  • Improved overall equipment effectiveness (OEE)

Better Product Containment and Working Conditions

The switch to a closed-loop conveying system has eliminated dust emissions and the material losses associated with traditional filtration-based systems.

On top of this, integrating pigging (pipe cleaning) transfer systems on the mill-base lines has made it possible to:

  • Maximize product recovery 
  • Reduce waste 
  • Improve cleaning efficiency and process traceability

Expanded Parallel Operating Capacity

The system architecture — with independent conveying lines including duplicated storage hoppers, blowers, and cyclonic hoppers — enables simultaneous feeding of two dispersers, effectively doubling the plant’s operational capacity at the solids loading stage.

Technical Assessment: Eliminating Manufacturing Bottlenecks

  • Elimination of the main process bottleneck (solids feeding) 
  • Simultaneous improvement across capacity, operational efficiency, and cleanliness
  • A step change from a design-limited system to a robust, scalable solution fit for demanding production environments

Automation of additive dosing for the manufacture of water-based coatings: Puma Group case study

Puma Group and its coatings division

Grupo Puma  is a leading business group in the construction materials sector and the largest manufacturer of mortars in Spain. With over 40 years of experience, it develops a wide range of solutions for construction, including adhesives, insulation systems, flooring, asphalt products and renovation solutions.

The group also has a division specialising in coatings, both water-based and solvent-based, for the manufacture of waterproofing and decorative paints for façades and fillers that can be applied to different surfaces. It currently has 37 production centres and a distribution network spanning four continents.

Product to be processed and project objective

The client manufactures coatings and coverings mainly for the construction sector. Within the framework of this project, the installation of additives is intended for the production of water-based coatings.

The incorporation of additives during the manufacture of paints and coatings is common practice in the industry, as they allow various properties of the final product to be adjusted and improved. Their functions include improving the dispersion of pigments and fillers (dispersants), controlling foam generated during the process (defoamers), stabilising the system by adjusting the pH, and providing specific properties such as biological resistance, gloss control, or modification of drying times.

These additives are normally used in small quantities and are incorporated at different stages of the manufacturing process, which requires precise and repeatable dosing to ensure the quality and homogeneity of the final product. They are usually supplied in industrial containers such as IBCs or 200-litre drums, so in many plants weighing and addition are done manually.

In this context, the aim of the project was to design and implement an automated system capable of managing the weighing and precise dosing of different additives into eight independent dispersion tanks. The installation had to guarantee speed, accuracy and repeatability in the additions, integrating into the existing production process and allowing the direct use of IBCs as storage tanks for the additives. The aim was to avoid frequent transfer or replacement of containers, optimise internal raw material logistics and improve the overall efficiency of the manufacturing process.

Oliver + Batlle solution

To solve the challenge, Oliver + Batlle designed an automated additive dosing system comprising the following main elements:

  • A 300-litre additive weighing hopper, made of stainless steel and equipped with load cells. It incorporates automatic valves for dosing 11 different additives: 9 of them dosed by gravity and 2 by pumping, due to their higher viscosity. The system also has manual valves with micro-switches for loading the stock IBCs of each additive.
  • Two pneumatic pumping units, designed for dosing higher viscosity additives.
  • A pneumatic transfer pump, responsible for transferring the product from the weighing hopper to any of the eight possible destinations.
  • A stainless steel distribution manifold equipped with seven automatic three-way valves, allowing the destination of the additive to be selected.
  • Eight automatic line shut-off valves, installed at the inlet of each of the dispersion tanks.
  • An electrical control and manoeuvring cabinet, equipped with a PLC and HMI touch screen, from which the operator can select the additive to be dosed, define the weight set point, manage stock loading and monitor the operation of the installation.
  • Two portable pump units on trolleys, designed for loading IBCs of additive stock.

Oliver + Batlle carried out all the engineering work for implementation at the plant, including the distribution of the additive IBCs, the weighing hopper, the pumping equipment and the layout of the pipes from the hopper to the collector and from there to the dispersion tanks.

The mechanical, electrical and pneumatic assembly was carried out by the customer themselves, under the supervision of an O+B technician.

Subsequently, the installation was commissioned with the participation of a mechanical technician and an Oliver + Batlle programmer.

During operation, additives compatible with each other are dosed and weighed in the hopper, from where they are automatically transferred to the selected dispersion tank. The system also incorporates a water cleaning cycle for the hopper and  flushing of the pipeline, ensuring that all the additives reach its destination.

The additive dosing control system was integrated into the factory’s automated system for executing complete recipes using the customer’s SCADA, establishing communication between the PLC of the system supplied by Oliver + Batlle and the plant’s main PLC.

Results and advantages of the implemented solution

Thanks to the implementation of this automated additive dosing system, the customer has significantly optimised manufacturing times.

The process has gained in precision, cleanliness and repeatability, eliminating the variability associated with manual dosing.

In addition, the system provides complete traceability of the process, recording the dosages carried out for each batch, including the additive code, target value, actual dosage value, destination, date and time of the operation.

Automation has also reduced the operational workload, minimising manual interventions and facilitating the work of the plant operator.

 

The main advantages of the implemented solution are:

  • Automation of the additive dosing process.
  • Greater precision and repeatability in each manufacturing batch.
  • Optimisation of process times.
  • Improved cleanliness and order in the plant.
  • Complete traceability of dosages performed.
