Technology 2007 vs 2022

Technology 2007 vs 2022 – Comparison of performance and operating costs in a real production process

Client profile: Investor transforming fixed costs into operating profit using Ecoline technology

The case study concerns a manufacturing company that has been operating a 2007 painting line for 15 years. Faced with rising energy costs, increasingly stringent customer demands, and the need to increase throughput, the company decided to completely replace its technology in 2022. The new investment was designed by Ecoline with a specific product portfolio in mind, where 80% are thin elements with a constant height of 1.5 m.

Strategic goals: Cost-effectiveness and production acceleration

The main driving force behind these changes was the need to drastically reduce utility consumption and increase paint shop throughput, which directly translates into production profitability.

Key performance indicators (KPIs) for the investment:

Reduction in gas consumption: Fuel demand reduced by almost 50%.
Increased workflow: A 50% increase in painting speed for thin parts (80% of production).
Process precision: Elimination of under-dried details, thick and under-baked coatings.
Quick return on investment: Generating operational savings exceeding PLN 500,000 per year (based on 3-shift operation).

Challenge: Inefficiency of old technology

The old line (2007 model) had rigid technological limitations. A common burner for the dryer and the 700 kW kiln prevented flexible energy control. At a constant speed of 1 m/min, thicker parts required drastic slowdown of the line to achieve proper polymerisation, which paralysed the efficiency of the entire plant. Furthermore, the lack of modern insulation generated enormous heat losses in the hall.

Ecoline solution: Customisation and intelligent energy management

Ecoline has designed a larger, more advanced line that, paradoxically, consumes significantly fewer resources thanks to the point-by-point optimisation of each stage.

1. Dedicated heating sections with modulating burners

Unlike the old system, the new line features dedicated modulating burners for the drying (175 kW) and firing (350 kW) ovens. This allows for smooth power adjustment to the current load, drastically reducing idle gas consumption.

2. Intelligent detection and energy savings

A part detection system with an encoder has been implemented. If a break occurs on the conveyor, the system automatically shuts off the pumps in the surface preparation tunnel. Additionally, a vapour condenser is used, which returns the hot bath to the tank, and air knives reduce the amount of water to be evaporated in the oven.

3. Thermals 2.0: Siphon furnace and premium insulation

A unique siphon furnace design minimises heat loss. The use of high-density mineral wool and panels eliminating thermal bridges means that the new line requires an average of 33 m³ of gas per hour, while the old line consumed as much as 63 m³.

Measurable investment results

Massive gas savings:

The new line generates savings of 60,000 m³ of gas per year, which translates into approximately PLN 215,000 in fuel budget savings.

Energy balance:

Despite the increase in electricity consumption (larger pumps and fans), the overall cost balance is highly positive. With three-shift operation, net operational savings exceed PLN 500,000 per year.

50% increase in productivity:

Most production (thin parts) is completed half as fast as on the old line, allowing for 50% more orders to be completed in the same amount of time.

Improved working conditions:

Thanks to the heat recovery system in the cooling tunnels, hot air emissions into the hall have been reduced, improving employee comfort and microclimate stability.

“Optimisation is not just about cutting costs; it’s about seeking efficiency. Replacing 15-year-old technology with the Ecoline solution demonstrated that a new, larger line can be half the cost to operate, while also being 50% faster. It is an investment that pays off not only in gas bills but, above all, in increased company capacity.”

Summary: An investment that pays for itself

A comparative analysis shows that operating an outdated paint line is a hidden cost that hinders company growth. Ecoline solutions – from modulating burners to a siphon oven – prove that a modern powder coating facility is a precise business tool that maximises profits while respecting environmental standards.
