Replacing chillers and recovering waste heat

Chillers are essential to regulate the temperature of machines and production circuits. Those at the Alban Muller plant needed to be replaced to improve the energy performance of the plant.

Furthermore, the Alban Muller teams had identified a significant heat loss. Indeed, there was no system in place to recover waste heat from the chillers.

Alban Muller set a goal to reduce CO2 emissions resulting from heat loss by 80%.

Cooling units replacement and heat recovery
with MyProject

The Alban Muller site called on Dametis to replace the cooling units and implement a more efficient heat recovery system.

The solutions provided by Dametis have led to 81.92% savings in 2 years on the gas bill for the hot water production area, exceeding the 80% target.

Challenge: Reduce carbon emissions by 50% by 2030

In March 2021, Alban Muller joined Croda International. The British chemical and cosmetics group has set ambitious decarbonization goals for its factory production.

Using 2018 CO2 emissions as a reference point, Croda International aims to reduce emissions by 50% by 2030 and 100% by 2050.

These goals target on-site direct emissions such as gas consumption and company vehicles (scope 1), as well as indirect energy-related emissions, particularly electricity consumption (scope 2).

Optimizing processes to improve performance with MyExpertise

1. During the initial visit, Dametis experts conducted an energy audit, inventoried the factory's equipment, and collected as much data as possible on gas and electricity consumption. After measuring the performance gaps between the current factory processes and their optimal levels, they proposed improvement areas to reduce CO2 emissions zone by zone.
2. During a second on-site visit, Dametis experts established a measurement plan and identified where to place sensors to enhance performance. For areas with insufficient data collection, they defined additional measurements to be taken to obtain relevant quantitative analysis.
3. MyExpertise implemented an action plan based on a decision matrix that helps prioritize intervention areas according to potential return on investment and implementation difficulty.
4. Dametis offers long-term energy support with follow-up on the action plan and dedicated studies on high-potential energy reduction points identified during the audit.
