“Linen is a natural resource, just as water, electricity and fossil fuels are, and should be preserved,” said Joel Jorgensen, VP of sales & customer services for Continental Girbau.
Linen is most damaged from chemicals used in the washing process and from the extreme heat found in the drying process. In order to reduce heat’s impact, hotels have begun installing moisture sensors in their laundry driers, which are able to track the heat present in the machines and either end the drying process early or adjust the temperature for linens that are sufficiently dry.
“Moisture sensors didn’t use to be accurate, but new technology has made them very accurate and inexpensive,” said Bill Brooks, national sales manager for UniMac. “If your machines aren’t running, hotels can also save on utility costs. It can help your ROI and improve your environmental footprint. It’s a win-win.”
Some laundry establishments have cut down on water use by re-purposing the water used in a wash for future washes, but Rick Kelly, VP of marketing & sales administration, feels that the expense for water in hotels has not yet crossed the threshold to make re-purposing effective.
Instead, Kelly believes hotels can save on water and energy by investing in washers with faster rinse speed. At a sufficient speed, washers can avoid running an extra rinse step, and in some cases the speed forces more water from the linens than normal, cutting down on dry time and the temperature needed to fully remove the moisture.
