What is a 7SO Softening Cartridge?

This pretty cool piece of equipment is used for food service and commercial applications. It can give you delicious specialty coffee, wonderfully strong espresso or refreshing, crisp ice tea. This cartridge reduces minerals like calcium and magnesium which cause hard water. It’s like having a mini water softener under your sink. This is ideal for hard water at a flow rate as high as 1/2 gallon per minute. The ion exchange technology is a carbon and resin blend. The cartridge has a psi range of 10-125, as well as, a temperature range of 35 to 100 degrees. The 2,000 grain capacity is ideal for high mineral content and low volume application. What is the proper way to use the 7SO (EV9607-04)? Usually it is a 2 stage setup. The first stage would be a MC2 (EV9612-56) filter. This reduces the chlorine, sediment, taste and odor. The precoat sub-micron technology reduces the dirt and particles as small as 1/2 micron. The 2nd stage is the 7SO, which reduces the hardness. Best operating procedure is to change the cartridge every 6 months just like most other filters. To determine cartridge life, divide total capacity of cartridge by the hardness in grains per gallon (gpg). So for example, 2,000 grains for the 7SO divided by 15 grains of hardness, you would exhaust this cartridge after running approximately 133 gallons of water through it. You can also change when hardness of treated water increases to more than 3 grains per gallon. Do not exceed recommended flow rate which is 0.5 gallons per minute. Don’t forget to flush the cartridge when you install it or change one out. You do this by running water through it for five minutes at full flow. This should be done no matter what filters you are using. The other great thing about this cartridge is that it fits all existing Everpure heads. No electrical connection is required. So if you have hard water in your foodservice location and want great tasting espresso we would recommend the 7SO.

How To Stop Slime!

Is slime taking over your ice machines? Don’t worry, slime contamination can be solved with the correct water filtration system. In a hospital, various environmental factors affect the ice. The problem with slime originates from filtration removing the disinfectant from the supply water to the ice machine.  By removing chlorine and chloramines, contamination can occur in the ice bins and nasty bacteria can multiply, leaving you with SLIME! To address this problem, Everpure has developed the 7SI cartridge. Everpure’s 7SI cartridge (EV9606-01) allows chlorine or chloramines through to help fight slime. 

7SI Cartridge

  • Specializes in slime and bacteria growth prevention
  • Reduces particulates down to 0.5 micron
  • Utilizes depth filtration and Fiberdyne™ media for superior dirt holding capability
  • Leaves chlorine and chloramines within water that is supplied to equipment which helps to reduce slime and bacteria growth in applications
  • Reduces system maintenance, service costs and buildup. Scale, slime, and bacteria growth can result in clogging of distribution lines, malfunction of probes, floats, pumps, solenoids and valves, and higher energy consumption
  • Sanitary cartridge replacement is simple, quick and clean. Internal filter parts are never exposed to handling or contamination
  • Can be used on Insurice® and Hybrid Manifold Systems
  • NSF® Certified under NSF / ANSI Standards 42 and 53

Features:

  • Cyst Reduction
  • Particulate Reduction
  • Capacity: 25,000 gallons (94,635 liters)
  • Maximum Flow: 3.5 gpm (13.25 lpm)
  • Qty. per Case: 0
  • Working Pressure: 10 – 125 psi (0.7 – 8.6 bar), non-shock
  • Max. Temp: 35 – 100ºF (2 – 38ºC)
  • H: 20.75″ D: 3.25″ Certifications: NSF42 NSF53

The 7SI cartridge is Everpure’s response to the ever-changing demands in the water filtration industry.  By keeping the disinfectant properties of chlorine in the water supply, we have removed the problem of slime without requiring additional costly equipment.
