Hydrocompus is truly dedicated to serving the electrocoating industry. We are a manufacturer, offering Ultrafiltration, Reverse Osmosis, and Anolyte Cell technology for this important application. We are proud to have more engineers, sales, and service staff serving the e-coat industry.

Ultrafiltration – Electrocoat painting is a process in which an object is dipped into a process tank and painted by means of Electrophoretic deposition. During the process, paint particles are suspended within a liquid medium and have a charged placed upon them. Under a high voltage DC current, the paint particles migrate to the part being painted and are deposited onto the surface, resulting in a highly corrosive resistant and durable paint film. The part is then rinsed several times, and the rinse water counter flows back to the main paint tank. Ultrafiltration must be used to remove the excess rinse water in the paint bath and balance the chemistry of the tank for a successful operation.

Ultrapure Water for Final Rinse – Reverse Osmosis systems are the preferred method for producing Ultrapure water for final rinse stages of electrocoating. Hydrocompus Reverse Osmosis Systems offer technologically advanced features at exceedingly affordable prices.
Hydrocompus Reverse Osmosis systems feature:

•Up to 60% energy savings over traditional RO systems
•Touch Screen HMI Control Panel & PLC’s are powerful yet easy-to-use
•Stainless Steel frames are standard on all models
•Our professional service team will be there for you years after your system is commissioned

Traditional De-Ionization (DI) technology can produce good quality water, but there are several drawbacks that are not a problem with RO. The following chart compares both technologies:

Comparison of RO vs. DI technology:

•RO purity is continuous while DI gets progressively worse as the resin nears regeneration
•DI chemicals are expensive and therefore operating costs are higher than RO per gallon of purified water
•RO membranes are a physical barrier that removes bacteria, viruses, algae and suspended solids while DI systems do not remove these contaminants
•DI uses two hazardous chemicals, hydrochloric acid (HCl) and caustic soda (NaOH), for regenerating the resin beds; these chemicals have special storage and disposal requirements
•RO systems have a continual concentrate effluent of 15-35%

Cleaner Baths – Alkaline and/or acidic cleaner baths are commonly used for the pre rinsing of metal parts before final finishing. Tubular Membrane technology has a very wide (1”) feed channel capable of handling exceedingly high concentrations of Total Suspended Solids (TSS), with consistent permeate quality for discharge or reuse via further processing. Hydrocompus Tubular systems can often offer a pay back of 3-6 months, while providing the following operational benefits:

•Up to 80% savings on cleaner solutions
•Up to 98% savings on waste hauling costs
•More consistent cleaner bath performance

Hydrocompus has developed a special line of Ultrafiltration membranes specifically for electrocoating. Proprietary V6 and A6 Ultrafiltration membranes offer low fouling and long membrane life through special membrane chemistries tailor-made for e-coat paint.

V6 (Cathodic) & A6 (Anodic) membranes – Synder’s V6 & A6 Ultrafiltration membranes provide optimal retention while maintaining high flux rates.

•The proprietary hydrophilic charge helps reduce fouling and extends membrane life (V6 only)
•For membrane cleaning, Synder only requires Power Flux Concentrate cleaning solution in addition to acid. Other membranes require multiple cleaning chemicals (up to five!) to “recharge” and clean the membrane.
•Integrated end plugs offer easy installation and maintenance during the lifetime of the elements

Ultrafiltration Systems – Hydrocompus offers custom designed systems to meet your specific needs and budget. Hydrocompus Ultrafiltration systems can be fully automated or manually controlled and a variety of instrumentation and components are available. Wetted parts are available in stainless steel, PVC or Polypropylene and stainless steel or epoxy coated carbon steel frames are both available. Along with proven quality installed at major auto assembly plants worldwide, Hydrocompus offers unparalleled after-sales service and support to ensure a successful e-coat operation.

Anolyte Cells – Anolyte Cells are a crucial component in Cathodic Electrocoat painting. Excess acid is released during the deposition process, which must be removed at a steady rate to keep the paint chemistry in balance. Anolyte Cells (or Membrane Electrodes) remove the acid via a positively charged anionic (or “selective”) membrane located in the shell of the anolyte cell. The Anolyte Cell also houses a positive electrode (anode) that drives high voltage DC current to the part being painted (cathode).

Hydrocompus offers two types of Anolyte Cells systems to meet your electrocoating needs. Contact Us to find out which one is right for you.

Tubular (TechCELL) – Hydrocompus Tubular TechCELL anodes provide better paint coverage than flat cells due to a greater electrical “throw angle”. The anionic membrane area is greater than the anode area, reducing electrical resistance and therefore, lowering operational cost. Hydrocompus anolyte delivery system supplies maximum flushing of the anode to remove corrosive oxygen, extending anode life.

“C” Cell (SuperCELL) – Hydrccompus is setting the standard with the latest “state of the art” C-Cell product line of high quality anolyte cells provides both original equipment manufactures and end users with value and performance. The Super Cell is ideal for automotive installations largely for economic reasons. This innovative design is available in three sizes to fit into any paint tank. It is available in both the traditional bolted design and the modular component design.

Modular SuperCells only have four bolts holding separate components together, reducing membrane replacement and maintenance time from hours down to minutes.
