Fyrquel®EHC Plus - Advantages

Distributor Oli Fyrquel - PT. Multimandiri Duta Selaras
Fyrquel® EH series fluids are ISO 46 viscosity grade triaryl phosphate ester type self-extinguishing hydraulic fluids designed for steam turbine electro-hydraulic control system application. Visit www.fyrquel.com to view a short video demonstration of the self-extinguishing fire safety advantage of Phosphate Ester type fluids. This unique self-extinguishing property of phosphate ester fluids is the mainreason that only phosphate ester fluids are specified for use by Steam Turbine OEMS. The latest edition of NFPA 850 Recommended Practice for Fire Protection for Electric Generating Plants was issued effective Jan 2010 and includes the 3.3.14.1 Definition Fire Resistant Fluid: “A listed hydraulic fluid or lubricant that is difficult to ignite and does not sustain combustion due to its low heat of combustion”. Phosphate ester fluids satisfy this NFPA 850 definition, other type fluids do not. Fyrquel® fluids reduce risks of spray, lagging and pool fires when using petroleum based and other non self-extinguishing fluids. The fluids are optimally designed to protect from valve erosion, have non corrosive compatibility with all metals, have excellent lubricating properties for long pump life, are operationally stable for long fluid service life, maintain viscosity without shearing during service, have excellent air release and low chlorine contents. Other type fluids have 2-3 year limited service life. An advantage of phosphate ester fluids is that viscosity remains stable during service giving these fluids the longest service life.

Fyrquel® EHC Plus is a third generation self-extinguishing improved phosphate ester electro-hydraulic control fluid designed for steam turbine application directly replacing earlier generation phosphate ester fluids. If changing from a non phosphate ester fluid, contact your Fyrquel Representative for technical assistance. It’s made using a new phosphate ester base stock that features a more sustainable product design, is OEM approved and compatible with prior generation phosphate ester fluids.

Overview
More Sustainable Product Design
- More environmentally friendly – readily biodegradable, also like all Fyrquel® EH series fluids recyclable using the Fyr-Back® waste alternative program. Standard fluid disposal not needed. Not currently available in all regions.
- Lower cost supply - same high value-in-use self-extinguishing property but at a better price.
- More worker friendly MSDS and product labeling – no specific GHS hazard identification required. Made from modern base stocks that are trixylenyl phosphate free. Not classified under GHS nor regulated for transport.
- Designed for longer service life .
- More thermally stable providing better resistance to fluid degradation.
- Better performance – improved air entrainment protection.
- Better quality - same needed low chlorine content, lower better fluid acidity, highest cleanliness design protecting valves and featuring a better resistivity specification.
- More secure supply – protected by a supply chain using more available modern base stocks.

ICL-IP has developed a summary of compatible materials of construction. Proper care in ordering components and replacement parts that are compatible with triaryl phosphate ester fire resistant fluids is essential. Component manufacturers and suppliers are familiar with the requirements of phosphate esters and compatible materials are readily available. The below recommendations are general in nature. Compatibility testing with compounded products is recommended to assure in-service performance.

WIRE INSULATION
Insulated wire requires an outer coating of material resistant to phosphate esters. The materials usually specified are nylon, silicone rubber, polyethylene, polypropylene, and Teflon® polymers. Polyvinyl chloride (PVC) is not recommended as an outer coating.
FILTERS
A variety of standard filters can be employed to maintain phosphate esters. The fluids are compatible with most common filter media such as paper, cellulose, synthetic fiber, and metals. However, when using filters, care must also be taken that seals, coatings, and adhesives are compatible with the fluid.
METALS
Phosphate esters have little effect on metals they may contact in operating systems, and are compatible with all metals. One of the most commonly used materials of construction compatible with phosphate esters is carbon steel. In adverse environments such as chlorine or caustic applications, the use of stainless steel should be considered.
PAINTS AND COATINGS
Standard paints and coatings are not compatible with phosphate esters. However, certain polyurethane and two-component catalyzed epoxy finishes are generally resistant. ICL-IP recommends that all interior tank surfaces remain uncoated. Fyrquel® fluids passivate metal surfaces while preventing corrosion.
