WATER TREATMENT SYSTEMS – WAREWASH APPLICATIONS
FEATURES
Hobart models WTSBSS-XL and WTSBSS-EXT warewash water treatment systems are designed to protect 
booster heaters and dish machines. They are ideal for 
 reducing existing scale deposits, scale prevention, cor 
rosion control, and are unaffected by high temperatures. 
The clear, high temperature housing allows for visual 
monitoring of replacement cartridges. Over time, the 
product in the ScaleStick™ between the feed holes and 
bottom will slowly dissolve and the level will drop. Replace the ScaleStick 
bottom. The small, compact design of both models will t 
into any small space being only, (W x H x D) 5" x 13 
x 5". Each model comes standard with the bracket and 
ttings needed for installation included with the systems. 
* Note: Capacities may vary depending on certain factors including flow 
rate, frequency of use, and pressure. Do not base cartridges change out 
on stated gallon capacity, but rather a visual inspection of the product 
level through the clear housings.
