Modular Filter Design for Quick Disconnect Systems

SFES PRO Filter systems utilize a modular head design allowing the unit to be a single stand alone filter (Single), or connected together into a multiple filters plumbed in series, parallel, or combo configurations.

A Series configured system

A series configured system simply means water passes through one filter then the next.

A Parallel configured system

Water passes through two or more filters at the same time increasing flow rate and capacities by 2x, 3x, or 4x of the standard Single System.

A Combo configured system

A combination of manifold and series configuration where two water outlets are desired, one with scale control and one without.

Most units applied will be a Manifold Configuration where the Inlet & Outlet ports are aligned and Union Connectors are used. For the Series and Combo systems, the Inlet and Outlet ports are not aligned on either the first head or the last and a Union Plug is used instead of a Union Connector. On the Combo system with 2 water outlets, one of the water outlets will be from the “Inlet” port.

SFES PRO Filter systems also allow for multiple Inlet/Outlet positions.

For Single and Manifold Units, water can flow to the left or the right and the Inlet/Outlet water connections can be on the same side or opposite sides of the system.

For Series or Combo Configurations, the water may flow to the left or to the right but the Inlet & Outlet water connections must be on opposite sides of the system.

SFES PRO Filter Systems are available in several connection configurations – 3/8” NPT Male & Female Connections, 3/8” Push Connect, and 1/2” Male NPT. An optional Pressure Gauge w/ Flush Valve is also available with 3/8” or 1/2” Male NPT Connections.

SFES PRO filtration/treatment offering is based on technologies that are not only proven effective in food service applications, but also are economical and easy to maintain

In water-fed food service equipment, 95% of water treatment is targeted towards chlorine/chloramine removal, mineral scale control, and corrosion control. Although SFES PRO products have the ability to address most any water treatment situation, the emphasis of the product offering is mineral scale control.


The removal of chlorine from water supplies is accomplished with the use of activated carbon filters. Available in various forms, activated carbon effectively removes 95+ % of chlorine from water supplies. Most water filter products incorporate some form of activated carbon filtration with excellent chlorine removal capacities and flow rates.


Unlike chlorine removal, controlling mineral scale deposits is a far more challenging proposition. Various methods have been used attempting to control mineral scale with varying success. Our technology for controlling mineral scale deposits centers around the effective and economical chemical treatment (HydroBlend™) using advanced scale control compounds specifically formulated to work in hot water equipment.

This example is of HydroBlend™ being inserted into standard filter cartridges providing consistent and effective equipment protection. HydroBlend™ is also available in stand-alone systems for use on booster heaters, tankless heaters, or whole facility applications.


Like chlorine, chloramine reduces the quality of beverages and also poses corrosion challenges to certain types of food service equipment like flash steamers. The removal of chloramine from water supplies is similar to chlorine removal. Activated carbon is still the main technology used with much longer contact times required to remove chloramine which means slower flow rates or larger filters.


Corrosion in water-fed foodservice equipment may be caused by various water factors. Corrosion is also specific to certain types of equipment. For example, chloramine in the water supply will not pose a corrosion threat to a coffee machine, but will be cause for concern for a flash steam combi oven.

Chlorides, either naturally occurring in coastal and desert areas or from salting of the roadways for melting snow will also pose serious corrosion issues to certain types of equipment, especially flash steam equipment like boiler-less combi ovens..

SFES Reverse Osmosis systems or a combination of the above technologies are used to address corrosion.
