larger image Conoco Hydroclear Diamond Class Heat Transfer Fluids are premium quality fluids specifically developed for use in liquid-phase heat transfer systems. They are available in two different formulations, "O/S" for use in open systems, and "C/S" for use in closed systems. Hydroclear Diamond Class Heat Transfer Fluids O/S and C/S each are available in two viscosity grades: ISO 32 and 46. They are formulated with high-quality, hydrocracked paraffinic base oils and advanced additive chemistry to provide outstanding thermal stability and low sludge-forming tendency for long service life and outstanding overall performance. Hydroclear Diamond Class Heat Transfer Fluids O/S 32 and O/S 46 are optimized for use in pressure-relieved, liquid-phase heat transfer systems equipped with expansion tanks, where there is a possibility of contact between the heat transfer fluid and air in the expansion tank. The additive system is fortified with oxidation and corrosion inhibitors to prevent fluid degradation and deposits from building up in the system. The O/S fluids are recommended for use in systems operating with continuous maximum bulk oil temperatures up to 550ºF (290ºC), and with intermittent maximum temperatures as high as 650ºF (343ºC). Hydroclear Diamond Class Heat Transfer Fluids C/S 32 and C/S 46 are optimized for use in pressure-relieved and expansion tank-equipped, liquid-phase heat transfer systems that are closed to the atmosphere and potential air contamination. The system must be nitrogen-purged, with no possibility of contact between the heat transfer fluid and air during operation. These fluids are fortified with special additives to prevent thermal degradation. The C/S fluids are recommended for use in systems operating with continuous maximum bulk oil temperatures up to 620ºF (327ºC), and intermittent maximum temperatures as high as 650ºF (343ºC).
