Envig CarShine 817 Deionized Spotless Car Wash System with Bypass Valve & Inline TDS Meter

Envig CarShine 817 Deionized Spot-Free Car Rinse System with Bypass Valve will give your vehicles, boats, or appliances its deserved shine without limescale stain, while the bypass valve can be used for mixed water use to get maximum resin life. Depending on water quality, the system can produce about 1000 gallons of TDS free water at 60 PPM of tap water. The inline TDS meter will leave you with no chance of mistake in knowing when to make a replacement.

Let your vehicle shine with TDS free water

Calcium and magnesium ions in hard water crystallize into hard-to-remove calcite stains that become noticeable especially on shining surface like a new vehicle, which can't be removed with towel. In DI system, all ions (TDS) are exchanged, leaving the water with pure H2O. No more worry about stain. And better enough, you don't even need to towel dry your vehicle. The inline TDS meter will save your the hassle and disturbance of checking water quality, leaving no chance of mistake in knowing when to make a replacement.

* No need to towel dry after wash

* Durable bypass ball valve for mixed water use

* Inline TDS to check water quality real time and anytime

* Properly regulated at 2.4GPM to preserve resin life and allow proper flow through sprayer or pressure washer, while enjoy zero PPM water

* Each system will remove at least about 180 gram of magnesium or 288 gram of calcium (check how many DI water it can produce below)

Use bypass valve for different water type

With the integrated bypass valve, you don’t need to make changes in water source or have two different set-ups during vehicle wash. Simply turn the handle for bypass mode or filtered mode. In bypass mode, water flow uninterruptedly for the powerful jet to wet, remove dirt, or wash off soap. In filtered mode, rinse your vehicle as the last step. The custom bypass valve is built with durable solid brass ball valve with swivel garden hose connector.

Properly regulated for your wash tool and resin life

The flow rate of the filter water is regulated at 2.4 GPM, a level purposefully chosen to maximize resin life and allow you to use pressure washer or nozzle sprayer of your choice, while maintaining zero PPM. It is an optimal balance that you would appreciate in avoiding some of the shortcomings of other systems. It is a design anchor point that we have always maintained in our CarShine systems.

Inline TDS meter for real time monitoring

To know when to make deionization resin replacement to avoid scale stain on your vehicles, you can simply check the in-line TDS meter conveniently, which will display of TDS of the filtered water real time and any time. If it gets to 5 PPM, you can still wash and rinse your car with no stain, but it is time to order replacement bags of resin.

  • Wet

    In bypass mode (bypass valve handle pointing to the bypass loop), wet vehicle with tap water.

  • Clean

    In bypass mode (bypass valve handle pointing to the bypass loop), rinse soap off vehicle with tap

  • Rinse

    In filtered mode (bypass valve handle pointing away from bypass loop), spray vehicle with spot free DI filtered water

  • Car

  • RV

  • Boat

  • Solar Panel

How much DI water can CarShine produce before the need of resin replacement

Each system can remove at least about 180 gram of magnesium or 288 gram of calcium. TDS is expressed as ppm or mg/L. Assuming you have only magnesium or calcium in your water, the amount of DI water in gallon can be produced is between 188000/(your TDS number)/3.785 (for magnesium) to 288000/(your TDS number)/3.785 (for calcium). Below are theoretical minimum DI water production capacities. In reality, you should see capacity in between the numbers

TDS (magnesium or calcium only)--------------------minimum DI water production (gal)

50---------------------------------------------------------944 - 1520

200---------------------------------------------------------236 - 380

500---------------------------------------------------------96 - 152

1000--------------------------------------------------------48 - 76

2000---------------------------------------------------------24 - 38

Add an Envig chloramine garden filter to extend the life your DI resin

Chloramine and chlorine are chemicals for city water disinfection. They are known to shorten the life of DI resin. Chloramine is a hard to remove chemical. Regular activated carbon does little in its removal especially at water flow of a garden hose. Envig catalytic carbon has 10 times more chloramine removal capability and can reduce chloramine from your city tap water up to 80% (chlorine is much easier and can be easily removed by the filter). It has been used to extend the life of DI resin in the car wash unit and other products that use DI resin.
