Laundry machinery manufacturer Lapauw goes for maximum energy efficiency

Lapauw International wanted to find out whether its latest industrial drying ironers could be even more energy efficient. Sirris conducted an EcoMechatronics Audit on one of the machines and concluded that there was scope for a 10-20% improvement.

The challenge | Energy efficiency of drying ironers

A European manufacturer of environmentally friendly industrial laundry machines, Lapauw International provides total solutions for, among others, laundry businesses, hotels, hospitals and textile manufacturers. Lapauw's gas and steam-heated ironers and folding machines enjoy international renown. 

Although Lapauw International's latest drying ironers are already very energy-efficient, the company was keen to find ways of enhancing its energy efficiency still further, on the strict proviso that performance levels would be maintained.

A second challenge was to gain a better understanding of the sub-processes involved in drying, more specifically the moisture transport. Lapauw wanted to optimise the design and operation of its industrial ironers, resulting in better moisture evacuation and better regulation according to the exact load of laundry.

The solution | EcoMechatronics Audit

To measure the moisture content of laundry and the eco-impact of its drying irons on productivity, Lapauw arranged for an EcoMechatronics Audit to be carried out. This audit, developed by Sirris and FMTC (Flanders' Mechatronics Technology Centre), analyses the ecological impact of machinery and makes recommendations for a more ecological machine design.

Measurement set-ups and sensors were placed on the customer's ironer in order to measure the energy consumption and productivity step-by-step for a variety of scenarios. The measurements uncovered significant potential: through a combination of measures, it would be possible to improve the energy efficiency of the ironers by 10-20%.

The result | Next generation of machines

Lapauw is committed to implementing a series of recommendations from the audit in the next generation of machines. The step-by-step approach of the audit not only provided insights for new designs of the same machines but has also enabled the manufacturer to learn lessons for similar machinery.
