Food Service

Water filtration is an often-overlooked aspect of foodservice equipment. Unfiltered or improperly filtered water can have negative effects on every aspect of your foodservice operation. It is important in food service so that water is not only safe but tastes great. Water softener (ion exchange) adds salt to the water. Phosphates add chemicals to the water. Chlorine has been used to disinfect water since the early 1900s. Some customers will not notice the taste of chlorine, but others will, and chlorine can drastically alter the taste of post mix beverages and coffee.

Another compelling reason to employ water filters is equipment longevity. While the use of chloramine (a mixture of chlorine and ammonia) is not a new technology, more communities are using it due to EPA mandates set in 2012. Chloramine damages stainless steel, polyurethane, and rubber.

Water softeners (ion exchange), Phosphates, Chloramines and Reverse Osmosis all alter the water in some way by either adding or removing from the water’s components (minerals). Filtersorb SP3 does not add or remove any components of the water and prevents and eliminates scale through Nucleation Assisted Crystallization (NAC).

Combi Ovens

It is important to protect combi ovens to ensure food grade quality. Any chef or caterer will tell you how damaging untreated or non-properly treated water can be particularly to equipment requiring this high level of steam. A combi oven can succumb to scale and corrosion within a matter of months depending on the frequency and usage. In most cases the reason why corrosion is occurring is the use of water softener (ion exchange) technology, scale inhibitors (phosphates), and RO systems due to the drastic change in the pH.

Tooker House – Combi oven

Added our duplex rack and (2) 20” special filters to this equipment. They were about to install a new RO system on because of the ongoing scale issues, which would have also caused further corrosion. This combi oven is 16 months old and operates 20 hours per day, 7 days a week. The racks were falling off and needed to spot welded. The previous recommended treatment ended up causing corrosion within 6 months. Upon contacting the manufacturer for warranty parts and service.

Only the special filters with NAC technology were used (NO LIME DE-SCALER).

From Alto-Shaam Operator’s manual

“Even water, particularly hard water that contains high to moderate concentrations of chloride, will cause oxidation and pitting that result in rust and corrosion.”

None of the cleaning supplies or instructions address the issue of oxidation or scale build-up due to high temperatures.

Ice Machines

Freezing water to make ice cubes causes the dissolved minerals in hard water to precipitate and coat the working surfaces. This leads to increased energy costs and poor quality ice production and eventually cause the equipment to break down.

An industry standard to maintain and clean ice machines is to use acid. Using acid is highly corrosive to the seals and gaskets within the equipment and eventually cause damage and leakage. Why not use our Special filter’s green technology, that stops new scale and eliminates existing scale over time? Saves money not only on replacement parts but labor on routine maintenance. We guarantee it.

Did you know that 70% of ice machine service calls are due to water-related problems?

Coffee Brewers and

Espresso equipment

In order to serve top quality coffee or espresso to your customers, it is imperative to start with quality water. We have continued to hear time and time again the water taste better after using the Special filter. Reverse Osmosis (RO) water is known to make the water acidic and using acidic water for and acidic beverage, such as coffee, doesn’t seem to make much sense. Blending the water, so that a portion of the water is untreated leaves in not only the minerals needed to make great hot beverages, but also the contaminants that the RO system is suppose to treat against. Or you could be like some and treat all of the water, then put back the minerals you just took out because uh yeah that makes sense. (We didn’t think so either) Or you could just use the Special filter that treats 100% of the water and leaves the calcium and magnesium in because nothing is added or removed from the water to produce the best tasting beverages.
Protect all of your kitchen equipment with a point of service (POS) (whole building) system and use the special filter as a point of use (POU) filter for equipment being used for food and beverages.
