alto-shaam now offers an improved water
filtration system for combitherm
® . The
combiguard™ 10 & 20 triple-guard water
filtration system filters dirt, sediment, and other
debris as small as 1/2 micron. This system also significantly reduces
chlorine content to protect against corrosive chorine compounds.
combiguard improves equipment efficiency, reduces service requirements
and extends the life of the combi oven. after installation, confirm that
water quality standards specified in this manual are being met. Filtration
systems include one filter cartridge. additional cartridges can be purchased
separately. refer to an earlier page for additional ordering information.
The combiguard™ Bws Blended water system utilizes reverse osmosis to
remove more than 97% of the total dissolved solids from water which can be
precisely blended with filtered and treated water.
