ABCO-NF fluid (USDA H-1) is a unique choice for either of these two situations.:
  • NON-FOULING
    When fouling is a problem, for many applications running on operation temperatures near the limits, and for operation under conditions where power cut-off might happen occasionally or frequently. It is often a problem also for most electrically heated systems. Non-fouling, the odourless fluid won't coat the system's heated surfaces with baked-on carbon when severely overheated. This NF feature is very topic in many applications within chemical industry.
     
  • NON-TOXID
    When fluid toxicity is a concern. Even though the situation is highly hypothetic, what will happen if the thermal fluid is leaking into the secondary side and contaminate the heated medium ?  The NF is FDA recognized as a food grade oil. It is harmless even after years of service. This NF feature is relevant in many applications within food industry e.g. frying, spray drying, baking, manufacturing of food ingrediences, pharmaceuticals and similar.
     
  • SUPPORT
    When a reliable and cost efficient operation is a demand. AB&CO offers annual or 6 month analysis of the fluid for determine the condition of the plant, fast supply of add-up NF from Copenhagen stock, efficient technical trouble-shooting of the systems by process heating specialists. AB&CO also offers a service contract for any of these features.

 

 

ABCO-NF DETAILS

The ABCO-NF heat transfer fluid is highly efficient, thermally stable and cost-effective.   Completely non-toxic, it is exceptionally safe to use and is easy to dispose.  Used fluid can be safely combined with spent lubricating oils and recycled locally (EPA, citation 57FR21524).  The NF fluid is specified in a broad variety of applications, world wide. It is tough and durable with a proven record of success under demanding conditions, yet is easy and safe to handle.

 

Fluid Fouling

Unlike conventional heat transfer fluids, the ABCO-NF will not cause hard carbon formation on heated surfaces.   Conventional heat transfer fluids, when severely overheated, will produce sooty carbon at the film layer.  Much of this carbon immediately adheres to the heated surface and bakes on, forming a crust.  As layer-upon-layer builds up, heat transfer – and in many cases flow – is impaired.  Although nearly impossible to remove without scraping, sandblasting or using chlorinated solvents, the carbon can ultimately break loose, and large chunks of it can circulate through the system impeding flows and fouling components.  Where fouling is extreme, heater tubing and electrical elements will stress and prematurely fail.  Under similar extreme overheat conditions, the NF fluid evolves small carbon granules.  These granules remain in suspension and are easily filtered out.

 

Environmental Safety

The NF has passed Bioassay.   Rainbow trout, fresh water shrimp and Gulf shrimp were exposed to water-accommodated fractions of the NF fluid. No organisms died, and there were no ill effects.  In the event of a release, you can use the same simple clean-up procedures employed for light lubricating oils.  Once gathered, the NF fluid can be combined with spent lube oils and sent to the local oil recycler.  There it can be converted into another useful material, preserving natural resources.  The crystal-clear NF contains no chlorinated hydrocarbons, aromatics, heavy metals, or sulphur or nitrogen compounds.

 

Fluid Toxicity

The ABCO-NF fluid is completely non-toxic.  It is certified by the FDA and USDA, by Canadian Agriculture and Health & Welfare and by New Zealand MAF for use with food and pharmaceuticals.  It also carries the USDA’s H-1 incidental food contact rating and is certified kosher by the Orthodox Union (O-U), the world’s premier kosher certifying agency.  Do not breathe vapor mists of any fluid (see the Material Safety Data Sheet for further information on these, and other conditions).

 

Vapour Pressure

The ABCO-NF fluid has an extraordinarily low vapour pressure – less than 1/3 of an atmosphere at its maximum operating temperature of 600F.  This and the fluid’s exceptionally low pressure drop permit the designer considerable latitude in the choice of lower-cost equipment.

 

Efficiency

The lower a heat transfer fluid’s viscosity, the less energy will be required to pump it through the system.  ABCO-NF's viscosity is among the lowest of available high temperature heat transfer fluids.  This means that less horsepower is needed for a given duty, and that a smaller pump and motor can be specified.  And lower power consumption continues to produce savings year after year.

 

Water in the System

The NF fluid is manufactured from natural feedstock and offers the same superb metal-coating and lubricating properties as the finest natural oils.  However, any water allowed to stand in piping, components or especially expansion tanks of thermal oil systems can cause severe corrosion.   Because the NF is immiscible with water (and is also slightly less dense), any water can be easily drained from the system’s low points, or the component’s drain valves.  Crack the low-point valve and allow fluid to drain into a beaker or clear water glass.  If you see a phase separation (one liquid "floating" on top of the other), continue to drain until no separation is observed.

 

Storing Your Fluid

Containers of heat transfer fluid should be kept in non-hazardous dry areas only.  Until ready for use, the container’s tamper-evident safety seals must remain intact.  Liquids should not be allowed to pool on the tops of steel drums.  In the afternoon and evening when temperatures decrease, the heat transfer fluid will cool and contract slightly.  A partial vacuum is created in the drum, and, if the bung’s O-ring seal is not perfect, liquid standing on the top of the drum can be drawn through, contaminating the fluid.  If drums must be temporarily stored outside, store them on their sides.

 

Pre-Cleaning the System

For optimal performance of both your system and its heat transfer fluid, we strongly suggest that piping, valves and other components be thoroughly cleaned before installation.  Mill scale, weld spatter and slag, quench oils, protective lacquer and varnish coatings, and dust and dirt can act to degrade the fluid, and can damage pumps and valves.  And lodging in restrictions, these contaminants can easily create the same low flow conditions that cause premature failure of systems and fluid.

 

Inerting the System

Immediately after completing installation of the system, we suggest you purge with inert gas.  Such purging can eliminate air and water vapour, and can substantially reduce corrosion.  And while purging, you can leak test the system using simple soap-bubble detection methods.  Finally, when you charge the system, any gas that becomes dissolved in the fluid will be inert, and fluid oxidation at start-up will be almost nil.

 

Charging the System

When charging the system, we suggest you fill from the bottom (a point near pump suction) using a small positive displacement pump — not the system pump.  Charging from the system’s low point can help reduce trapped air in the system, which will substantially reduce the entrainment of gas bubbles and resultant pump cavitation.

 

Fluid Disposal

Because ABCO-NF heat transfer fluids are produced from natural feedstock, they are exceptionally safe to use.  Easy to dispose, used ABCO-NF fluids can be safely combined with spent lubricating oils and recycled locally (EPA, citation 57FR21524).  AB&CO strongly encourages recycling of used heat transfer fluid to conserve natural resources and to minimize the problem of liquid waste in landfills.

 

Fluid Analysis

Overheating, oxidation and contamination of your heat transfer fluid can significantly reduce its ability to perform.  Product quality will suffer, and in severe cases considerable damage to your thermal oil system can result.  Periodic analysis of your fluid can allow you to detect problems in the early stages and achieve substantial savings.

 

Quality Control

We thoroughly test each batch of heat transfer fluid to ensure absolute conformance to tight product specifications.  Each shipment is traceable to its master batch, with test results archived at AB&CO.

 

Technical Assistance

Our technical expertise is available to you in the conceptual stage, during planning and design, and through system construction, start-up and operation.  We want to work closely with you in the recommendation of proven thermal fluid systems, components, supplies and procedures.  We also advise on system cleaning and repair, should these become necessary.  And if your application calls for fluids that we are unable to provide, AB&CO TEKNIK will assist you with the names and phone numbers of competitors’ engineers that can help.

Health Effect Information

ACUTE EFFECTS

EYE CONTACT
NF is non-irritating to the eyes upon direct contact.

SKIN CONTACT
NF is not expected to cause any skin irritation upon direct single or repeated and prolonged contact; however, similar chemical composition products applied to the skin of laboratory animals resulted in minimal to slight dermal irritation.

INHALATION
NF has a low vapour pressure and is not expected to present an inhalation hazard at ambient conditions. Caution should be taken to prevent aeroionisation or misting. The permissible exposure limit (PEL) and threshold limit value (TLV) for the fluid as oil mist is 5 mg/m3. Exposures below 5 mg/m3 appear to be without significant health risk.

INGESTION
Ingestion is relatively non-toxic unless aspiration occurs. ABCO-NF has laxative properties and may result in abdominal cramps and diarrhea. See Personal Health Protection section below.

CHRONIC EFFECTS

On rare occasions, prolonged and repeated exposure to oil mist poses a risk of pulmonary disease such as chronic lung inflammation. This condition is usually asymptomatic as a result of repeated small aspirations. Shortness of breath and cough are the most common symptoms. Aspiration may lead to chemical pneumonitis which is characterized by pulmonary oedema and haemorrhage, and may be fatal. Signs of lung involvement include increased respiration rate, increased heart rate, and a bluish discoloration of the skin. Coughing, choking and gagging are often noted at the time of aspiration. Gastrointestinal discomfort may develop, followed by vomiting, with a further risk of aspiration.

CARCINOGENICITY

Emergency & First Aid Procedures

EYE CONTACT
Immediately flush eyes with large amounts of water and continue flushing for 15 minutes. If fluid is hot, treat for thermal burns and take victim to hospital immediately.

SKIN CONTACT
Remove contaminated clothing. If fluid is hot, submerge injured area in cold water. If victim is severely burned, take to a hospital immediately.

INHALATION
ABCO-NF has a low vapour pressure and is not expected to present an inhalation hazard at ambient conditions. If vapour or mist is generated when the fluid is heated or handled, remove victim from exposure. If breathing has stopped or is irregular, administer artificial respiration and supply oxygen if it is available. If victim is unconscious, remove to fresh air and seek medical attention. Do not use compressed oxygen in hydrocarbon atmospheres.

INGESTION
May act as a laxative. Do not induce vomiting due to possible aspiration. If vomiting occurs, lower head below knees to avoid aspiration. Seek immediate medical attention.

 

Personal Health Protection Information

EYE PROTECTION

Eye protection is not required under conditions of normal use. If the fluid is handled such that it could be splashed into eyes, wear plastic face shield or splash-proof safety goggles.

SKIN PROTECTION
No skin protection is required for single, short duration exposures. For prolonged or repeated exposures, use impervious synthetic rubber clothing (boots, gloves, aprons, etc.) over parts of the body subject to exposure. If handling hot fluid, use insulated protective clothing (boots, gloves, aprons, etc.)

RESPIRATORY PROTECTION
Respiratory protection is not required under conditions of normal use. If vapour or mist is generated when the fluid is heated or handled, use an organic vapour respirator with a dust and mist filter. All respirators must be NIOSH certified. Do not use compressed oxygen in hydrocarbon atmospheres.

VENTILATION
If vapour or mist is generated when the fluid is heated or handled, adequate ventilation in accordance with good engineering practice must be provided to maintain concentrations below the specified exposure or flammable limits.

OTHER
Consumption of food and beverages should be avoided in work areas where hydrocarbons are present. Always wash hands and face with soap and water before eating, drinking or smoking.
