As a drycooler consumes much less electricity than a water chiller, it is beneficial to make best use of the cool air in winter and mid-season to directly cool the process fluid using the drycooler instead of the water chiller. This system will therefore considerably reduce your annual electricity consumption. 586 586 CATALOGUE 2021 )ABd( esin ni noitcudeRupniewo C o n t r o l w i t motor EC h h it E w C l o m o r to rt n o C o-9trP75255%%%
