FAQ

I AM INTERESTED IN THE CARBON CANISTER (CRC). WHAT SIZES DO YOU OFFER?

The Carbon Canister (CRC) is a reusable device to remove organic impurities from metal-finishing solutions. It is available in lengths of 6, 10, 15 and 20 inches (15, 25, 38 and 51 cm) and in diameters of 4-1/2 and 7 inches (11.5 and 18 cm). Carbon capacity ranges from 1 to 9 lb (0.45 to 9 kg).

The CRC features a machined polypropylene head that fits snugly into the pump for secure mounting. A rigid porous polypropylene tube surrounds the carbon.

You can refill the CRC with Flo King pelletized carbon or with plating-grade granular carbon in the appropriate mesh size from other companies (we do not sell granular carbon).

The CRC includes a 1.5-inch-diameter (3.8-cm) reusable filter cartridge. Alternatively, you can use a conventional
2-1/2"-diameter disposable filter cartridge.

WARNING! Never use powdered carbon in the CRC! Powdered carbon is too fine and will pass through the porous polypro tube, causing the solution to turn black.

Before carbon treatment, it is necessary to use FILTER CARTRIDGES to remove dirt and other inorganic particulates that could clog the CRC. For filtration, we offer Poly-Spun Disposable Filter Cartridges and Magnum Reusable cartridges.

FLO KING CARBON PELLETS
There are two types of Flo King carbon pellets — High Grade and High Tech. The High Tech carbon pellets are most popular for critical plating applications and cost more than the High Grade pellets.

CRC WITH ION-EXCHANGE RESIN
Only a very few customers use the CRC with ion-exchange (IX) resin to remove metallic impurities from solution. And those applications are typically for very small tanks — less than 30 gallons (110 liters).

Many IX applications require very large resin beds — more than our largest CRC can hold. We also do not sell IX resin and cannot provide guidance on resin requirements.
