BRIGHT OUTLOOK


FOR LOWER LAUNDRY TEMPERATURES


Improving sustainability doesn’t have to mean an increase in cost, thanks to innovative products. Here, Diversey Care discusses optimising the laundry process and reducing cost simultaneously.


Businesses with on-premises laundries are realising they can make significant utility cost savings and promote better sustainability with new lower-temperature processes. But they are not prepared to compromise on results that could jeopardise their hard-won reputations by giving customers an excuse to complain. Any switch to alternative, lower temperature laundry processes must be supported by the right detergents and wash programmes.


Clax Advanced is an innovation from Diversey Care meeting all the demands of a superior low temperature wash programme. This, and other products in the range, contains a wider range of ingredients than its predecessors and incorporates innovative actives to perform specific functions with greater subtlety. The objective is to make laundry operations quicker, simpler and safer. Clax Advanced can be used with modern machines to support superior fabric cleaning and disinfection at lower temperatures.


Washing at lower temperatures saves costs because less energy (gas or electricity) is needed to heat the water. In addition, less water is needed for cooling the wash load, thus reducing the number of rinses. Standard wash programmes tend to heat water inside the machine, rather than using external supplies, which takes time. Combined with a reduction in the number of rinses, this means the wash cycle can be completed more quickly at lower temperatures.


All else being equal any machine can wash more loads in the same period, which means better productivity for the operator with reduced costs. Lower temperatures and shorter cycle times normally result in less scale deposited on a machine’s heating elements,

Sealed Air is committed to helping customers achieve a more sustainable business, by reducing greenhouse gases while cutting operating costs. The success of Advanced has been validated in multiple countries around the world, including luxury hotels and nursing homes, with substantial operational savings* in conserving energy and water while reducing waste. The wash performance and utility savings have also been certified by Hohenstein laboratories - an independent well established research institute for laundry.

which improves equipment efficiency and lifetimes. Finally, fabrics last longer and need replacing less often if not exposed to high temperatures.


Independent studies have shown that by reducing the wash temperature by 20°C – in combination with the right detergents and programme - can reduce water and energy consumption by up to 35%, and extend linen life by more than 30%.


The Customer Case


for Lower Temperatures A Diversey Care hospitality customer wanted to assess potential energy savings across its estate of on-premises laundries without compromising quality of wash or adding significantly to product cost. Diversey Care proposed a single-site trial with Clax Advanced 40°C and Clax Bright, its low-temperature destainer. This provides excellent hygiene at 40°C and has been shown to be kinder on cotton than typical peroxide destaining processes, extending the life of fabrics by more than 30%. It is used with existing detergent systems in the same equipment and simply replaces the old destainers so no capital expenditure is required.


The machines on site were reprogrammed to reduce the temperature of the three main wash cycles by around 20°C. The hotel saved almost £300 in monthly energy and water bills during the trial. Shorter cycle times allowed more washes to be completed than were possible at the original higher temperature. Overall energy and water consumption was considerably lower, reducing by 50% and 30% respectively. The replacement products were slightly more expensive but the difference was more than offset by the energy and water savings.


The cost and time-saving benefits of lower temperature laundry are clear. In most cases the changes required amount to little more than the choice of innovative products, simple reprogramming of existing equipment and some basic staff retraining. This means little or no upfront investment is needed before the savings start to build up. Diversey Care is able to advise on the right approach and provide evidence to support the cost and time-saving benefits.
