CombiGuard™
FI-23014 shown
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 page 6 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.
