flow in and out. In order to achieve maximum efficiency and to achieve smooth buffering and distribution of water supply, a 10,000L stainless steel skid mounted buffer tank was incorporated into the design, including a steam sparge and duplex pump unit.


Results are already very promising. The system meets its engineering design conditions and reclaims more than 75% of the energy present in wastewater. The clean water temperature is increased from 12 to 37°C, ideal for the wash process. In the longer term, the system will reclaim on average 660kWh, generating savings of 3000MW/year, which is equal to 300.000m³ of gas or the consumption of 200 households.


The environmental impacts are significant, with considerably less steam needed to heat the washroom equipment and the discharged wastewater is cooled well below 30°C, in line with strict European wastewater legislation.


Dave Aveyard, Christeyns’ Director of Ireland Operations, commented: “The commercial laundry industry has faced unprecedented challenges due to the COVID pandemic and the impact this had on the hospitality sector. It continues to face additional challenges brought about by the significant increases in the cost of energy supplies.


“It’s fantastic to see companies like Celtic Linen face these challenges head on by investing in technology that will help them to stay competitive, and make carbon savings that contribute towards efforts to limit global greenhouse gases.”

Heat-X Energo V20+ What is it?


The Heat-X Energo V20+ is a shell and tube heat exchanger, designed for effective water-to- water heat transfer in laundries.


How does it work?


The heat exchanger is made up of a bundle of tubes placed inside a pressurised shell. One fluid runs through the tubes and transfers heat to another fluid that flows over the tubes.


Key features:


• Saves energy in washing, drying and finishing.


• Provides compliance with wastewater regulations.


• Plug-and-play system that’s easy to install. • Multiple monitoring and control options. • Automatic flow matching. • Requires minimal maintenance.


Savings:


• Average 50% saving on energy in wash process.


• Up to 20% saving on energy in the drying and finishing process.


• The more efficient rinsing process also reduces water usage.
