Mobil Nyvac FR 200D
High Performance Fire-resistant Hydraulic Fluid
Product Description
Mobil Nyvac FR 200 D is an extra high performance water-glycol type fire-resistant hydraulic fluid. It is formulated
with diethylene glycol as the main glycol component. The product does not contain ethylene glycol. Mobil Nyvac
FR 200D provides excellent protection against rust and against vapour phase corrosion. In hydraulic pump
tests, it has shown a high level of antiwear performance. A high viscosity index makes Mobil Nyvac FR 200D
effective over a wide range of operating temperatures. Its foam resistance, low temperature flow and storage
stability are also excellent.
The fire-resistant properties of Mobil Nyvac FR200D arise from its water content. Even when the fluid is sprayed
at a pressure of over 200 bar / 3000 psi from a diesel injector nozzle into a gas flame it will not ignite, nor will it
when dropped onto molten metal. The water content is important and must be maintained at 38% to retain
optimum fire resistant properties and its viscosity characteristics. Viscosity increase due to loss of water by
evaporation can be easily corrected by adding deionised water to the product. It is not recommended for use in
systems operating at bulk fluid temperatures above 65oC. Mobil Nyvac FR 200D is compatible with packings,
gaskets, hoses and accumulators made from materials normally encountered in hydraulic systems, except items
made from polyurethane, leather or cork materials. Mobil Nyvac FR 200D is approved by Factory Mutual (FM)
as a Group I HF-C fluid.
Mobil Nyvac FR 200D’s wide application capability and excellent performance make it the product of choice
among many industrial users.
Features and Benefits
Mobil Nyvac FR 200D is a key member of the Mobil brand of fire-resistant hydraulic fluids. Mobil Nyvac FR 200D
was developed in conjunction with hydraulic equipment builders to meet the needs of moderate pressure
applications where fire-resistance properties are critical, and where good lubricity and product life are also
required.

Applications
In common with all other water-glycol type fluids, Mobil Nyvac FR 200D is not compatible with typical type paints.
Epoxy or phenolic resin based paints are suitable. Mobil Nyvac FR 200D should not be mixed with other types
of fluids. While it is compatible with other water-glycol type products, admixtures may detract from the properties
of the Mobil product. The water content is important and must be maintained at 38% to retain optimum fire
resistant properties and its viscosity characteristics. It is not recommended for use in systems operating at bulk
fluid temperatures above 65oC.
Mobil Nyvac FR 200D is recommended for use in all types of hydraulic pumps and motors operating close to a
source of ignition, providing the manufacturers instructions are observed. Typical applications include:
• Diecasting machines and presses
• Combustion regulators
• Furnace door openers
• Ladel-tilting mechanisms
• Glass drawing machinery
