Upsell Corrosion Protection to Extend Product Life in Harsh Conditions

LOUISVILLE, KY – Hope springs eternal and so does coolant from a corroded tube. Corrosion is a natural process and can be responsible for a lot of heat exchange replacement work, especially in coastal climates. In coastal areas, moisture and salt wreak havoc resulting in metal deterioration on heat exchangers. For you it is business, for your business customers it can mean serious downtime and loss of production. For Se-Cliff Coatings, a NARSA member since 1974, helping you help your customers with their corrosion issues is what they do.

Sometimes too much of anything turns ugly. Case in point are those customers who have to operate businesses and even emergency equipment in briny atmospheres. Extending heat exchange product life cycles is what corrosion protection is all about. Adding a few months, maybe a year to the life of radiators or coil can add up.

The people out for the recent NARSA HD Conference here at the Marriott East had a great opportunity to learn a little more about corrosion from Tom Clifford, sales director North America and Europe for Se-Cliff Coatings, LLC. He also pointed to the opportunities that heat ex- change specialist’s business can help its customers by supplying products that have improved corrosion protection.
One can never prevent metal corrosion completely but there are products readily available that can reduce and retard the effects of corrosion. Corrosion begins immediately as new metal products like heat exchangers are exposed to the elements.

Tom shared some slides on where corrosion occurs and there are no surprises that the severe areas are coastal. One slide showed that all coasts were swathed in red (severe) and that the Cape Kennedy/Fort Pierce region of Florida has the highest rate of corrosion for HVAC systems in the U.S.

Tom pointed to other areas that may be corrosion contributors: salt, magnesium, coal mining; steel factories; high road salt areas; agricultural markets; petrochemical plants; marine; and food processing.

From a sales and marketing point of view, Tom said the case for corrosion protection on metal parts in general would include:

  • less engine wear, longer engine life;
  • less maintenance to the engine;
  • continued engine performance and power;
  • maintain near-original fuel-use levels;
  • maintain low particulate emissions levels;
  • less emergency failure, less downtime;
  • reduced interruption of production, profits;
  • much less total failure and reduced replacement costs of units and labor;
  • a value added product that solves an expensive maintenance issue.

He listed several exterior coating technologies that are currently available. They include: paint, Copon and other specialized paints; powder coating, Heresite, E-Coat (Electrodeposition) which his company uses, and spray hydrophilic. Tom also addressed a list of his suggested criteria to consider when choosing a technology. That list includes:

  • Corrosion retardant properties that meet all pertinent ASTM standards for salt water, and/or the specific application contaminants with no propensity for corrosion creep to occur.
  • Electrochemical and physical adhesion properties that meet applicable ASTM standards for cross-hatch adhesion.
  • Coverage – 100% guaranteed in writing.
  • Durability, flexibility.
  • Impact resistant capable of handling in-field abuse and power washing.
  • Consistent, reproducible coating thickness – no matter the core’s geometry or base metals used.
  • Zero bridging between fins and/or between louver edges.
  • High edge cove rage.
  • Green technology – can units be repaired and discarded safely (NSA Approved)
  • Military approval.
  • Warranty against defects or failure to protect against corrosion.
  • Cost competitive and efficient.
  • Supplier adheres to appropriate ISO process/production standards.
  • Minimum loss of heat transfer rate of less than 1% of capacity to transfer heat.
  • Minimum loss in air pressure drop.The coating should not significantly retard airflow rate as it passes through heat exchanger.

Tom explained the E-Coat process that his firm uses in Texas, Kentucky, New York, Michigan and Italy. E-Coat is a method of painting that uses electrical cur- rent to deposit paint. It is a highly efficient and automated process. Paint deposition is regulated by voltage and it has the ability to coat interior cavities without bridging fins or louvers.

This process works on new product only (clean, unpainted cores). The product must be able to withstand a 385°F process. Product can be copper, aluminum or steel. Other considerations include turn-around time (5 to 7 day typical) and the supply of a reusable shipping box or container.

Bradley edgar asks “How’s Your Aftertreatment Treating You?” PDF Print Email

Bradley Edgar asks “How’s Your Aftertreatment Treating You?”

LOUISVILLE, KY – News updates, trends, market projections, innovations, design and new cleaning techniques, it doesn’t get any better for the DPF crowd assembled for the HD Conference here in September. Dr. Bradly Edgar of Red Fox Resources returned to the NARSA podium after his debut last year in Buffalo with a presentation chock full of knowledge.

Bradley Edgar has been involved in emissions for twenty-plus years and holds a Ph.D. in mechanical engineering with focus on combustion, heat transfer and air pollution. His best asset is his ability to deliver technical and business information in a manner that is easily understandable.

Among the news items, certainly booming truck sales is at the top of every truckers list. Since the meeting, ACT Research says over the past 12 months Class 8 orders have totaled 503,500 units. The last record year was 2006, when the build reached 376,000 units. That is good news. Really good news is that all have diesel emissions aftertreatment systems.

Maybe not such good news is that all the truck makers have electric truck programs in the works.

Brad also pointed out that now gasoline particulate filters are in production in Europe for light duty vehicles. He said these gasoline particulate filters (GPFs) are very similar in design and function, but smaller.

He pointed out the “sweet spots for service” are the larger trucks with serviceable DPFs which he estimated to be 2.6 million engines in 2018 but projected to reach 12.5 million by 2027 when the market reaches maturity. He told them, “Future trends . . . are here.” That includes:

  • more compact designs;
  • DOC, DPF and SCR integrated into single package;
  • SCR is becoming more effective;
  • SCR catalysts may be coated on DPF;
  • extended cleaning intervals with better oil control;
  • sensors and On-Board Diagnostics continue to improve.

He went on to provide a detailed look into the evolution of the technology, differences in the designs, and the fundamental concepts of cleaning. His comments on thermal and air-cleaning included:

  • Temperature ramps and ranges
    • (212-572°F): coolant, water, oil, fuel starts to evaporate
    • (1100-1200°F): soot oxidizes
  • Watch outs
    • Vaporized fluids are smelly and can create a mess
    • Too much soot, or oil soaked DPF can ‘runaway’ and lead to overheating, melting or fire
    • Load parts so they can entrain air (vertical is best)
  • Multiple steps and sequence can be important
    • Blow-Bake-Blow again: First blow cycle removes excess carbon
    • Bake-Blow-Bake again: Ash plugs can trap carbon and keep oxygen from getting to soot
  • Weigh parts before and after each step - Measuring weight/flow at each step is good practice
    • Lots of soot: could be engine problem - Lots of ash: oil control or too long between cleaning
    • Lots of oil/coolant: leaking/failed turbo, fuel injector, EGR cooler
  • Pay attention and take good notes
    • There is a learning curve

Adding perspective to the DPF development, Edgar provided a brief history. From 1980 to 2000, engine makers considered a number of different designs which resulted in a variety of materials and regeneration strategies were considered. He said the earliest applications were in underground mining.

By the 2000’s, the wall flow filter be- came the design of choice. It was also around then that California and EPA sponsored voluntary and regulated retrofit pro- grams. By 2007, the level of permitted particulate matter was reduced by 90% and that meant DPF technology would be required. DPF regeneration was based on catalyst technology with engine management. In 2010, NOx mandated reductions insured that urea SCRs were required. DPF regeneration became easier.

DPF design has settled. Materials used include: cordierite, silicon carbide, aluminum titanate. Leading manufacturers include: Corning, NGK and Ibiden.

Dimensions are from 6 to 13 inches in diameter with lengths from 6 to 15 inches, and cell density of 200-300 cells/in2 (cpsi). Today’s DPFs feature high filtration area per volume, high filtration efficiency (98 per- cent of particles), low pressure drop, high melting point, low thermal expansion, and can be coated with catalyst. According to Edgar, wall flow designs seemed to be here to stay for a while.

Serviceable DPFs are fastened with gas- kets and seals. Filters for Class 4-6 are more difficult to clean and in some cases non- serviceable. Filters for Class 2-4 engines, are not designed for cleaning. DPF clean- ing basic tools and processes include:

  • Heat to oxidation temperature of carbon (baking);
  • Reverse backflow of compressed air (blow);
  • Aqueous cleaning: water jet, flush/irrigate, ultrasonic;
  • Combination of methods usually required.

Edgar outlined current filter diagnostics in play which include:

  • Scale for weight;
  • Flow bench for pressure drop;
  • Pin test for cell blockage;
  • Ultrasonic device for cracks;
  • Borescope;
  • Light test.

Edgar pointed to the parts and service opportunities that cleaning can provide. They include: service revenue; aftermarket DPF/DOC sales; replacement parts sales (DPFs, gaskets, clamps); upstream engine work; and income from parts recycling.

 
Global Cost of Corrosion Over $2 Trillion PDF Print Email

Global Cost of Corrosion Over $2 Trillion

MANITOWIC, WI – In the radiator business, the name Heresite is recognized by many as a reddish brown coating that is used to retard corrosion. Heresite is more than that. It is a company with global reach that provides corrosion solutions for a host of industries with a number of different products and processes.

Brand awareness is one of the reasons that Peter Hellman be- came the fourth owner of the company founded in 1935. He also saw potential in the corrosion protection business. Hellman improved processes, people and formulations, including reducing lead times from 6-8 weeks down to 2 weeks. According to Hellman, the annual worldwide cost of corrosion is over $2 trillion, which represents 3% of the world’s GDP. In the U.S., the annual cost of corrosion due to direct damage, increased maintenance and downtime is approximately $1 trillion.

Peter said about 90 % of their business is coating for heat transfer equipment which they have been doing since ‘60s. Markets they serve include HVAC and commercial refrigeration heat transfer coils and unitary/rooftop equipment; industrial pro- cess equipment like compressor rotors, valves, pump housings; radiators and industrial process coolers, charge air coolers, fin fan coolers, intercoolers; and air fume handling equipment such as fans, blowers, fume hoods, louvers.

Heresite was a first-time NARSA HD Heating and Cooling Conference exhibitor at the recent event in Louisville. Peter said that they are looking to increase awareness and business among radiator shops and manufacturers.

Demand for their coatings are the usual high salinity coastal regions and in environments exposed to high humidity, corrosive chemicals and fumes. Typical markets include: wastewater treatment plants, refineries, chemical plant, telecommunications and data centers, fossil fuel power plants, food processing facilities, airports, oil drilling platforms, as well as convention centers, and hotels.

They offer several different basic ways for protection. They can do it for you at their Wisconsin plant with Heresite’s P-413 baked phenolic epoxy. They also have products that can be spray-applied in the shop with their VR-514 air dry phenolic. An aerosol version of this product (VR-514t) is also available for smaller jobs and touch-ups. The third option is to use one of their 12 certified applicators, four of which are located in the United States. Heresite is active in 30 different countries including Canada, France, Italy, Mexico, South Korea and Dubai.

Peter said that they have one spray application for shop applications today (VR-514) and they will be releasing another soon (ES- 600). ES-600 will premiere at the January 2019AHR Show in Atlanta, GA. Other coatings include high bake phenolics for industrial applications such as tank liners.

Interesting note is that one of the certified applicators is Rahn Industries which has history with NARSA back into the ‘70s. Bill Han was the CEO and Rahn at the time was a leading supplier of automotive aftermarket air conditioning condensers. Rahn was a regular advertiser in the “Automotive Cooling Journal” which was renamed “The Cooling Journal” 15 years ago. Today Rahn Industries is a HVAC/refrigeration coil manufacturing company.

In marine/salt air applications the corrosion factors include chloride (salt spray, marine fog), humidity and sunlight.

For wastewater treatment, sources for corrosion include: acidic gases (hydrogen, sulfide, and ammonia), low pH condensate, and humidity.

Industrial urban markets corrosion factors are nitrogen and sulphur oxides, acid rain, low pH condensate, potential particulate chlorides, sulfates, sulfuric acid and carbon compounds. Protection from ammonia and nitrogen compounds, organic acids, sulfur and formic acids.

Sources of corrosion in food processing is from sanitizing chemicals, disinfectants, fumes and humidity. Transit and mining corrosion factors include: magnesium chloride, sodium chloride and hydrogen sulfide. Heresite works with customers to recommend the best process and coating. Corrosive environment considerations include:

  • Corrosive agent(s) and estimated concentrations;
  • Type of exposure (fume, splash, immersion);
  • Operating environment (temperature and humidity);
  • Coil type and construction (cold water, evaporator coil, steam coil. Is condensation likely to occur? Materials – copper tube, aluminum fin);
  • Coating experience (has the customer used a coating for this previously? What were the results?).
