Introduction

The Dormont OneFlow® Anti-Scale Hot Water Systems are
intended primarily for use with commercial dishwashers. In this
application they are installed between the hot water supply and the
booster heater in the dishwasher. There may be other hot water
applications for OneFlow Hot Water Systems where the feedwater
temperature is between 100°F (38°C) – 150°F (66°C).

Dormont OneFlow will reduce or illiminate scale formation in the
booster heater as well as reducing spotting and streaking normally
associated with hard water.

much lighter than a water softener and may appear to be nearly
