MOBIL SHC CIBUS 68 is a NSF H1 Registered Heat Transfer Oil
Mobil SHC Cibus™ 68 HT is a fully synthetic high performance heat transfer oil intended for use in closed, indirect heating installations where NSF H1 registered lubricants are required. It is formulated to resist thermal cracking and chemical oxidation which in turn can mean a longer service life and lower propensity for deposit and sludge formation.
The viscometrics of Mobil SHC Cibus 68 HT have been carefully selected to help provide effective heat transfer and maximize system efficiency. The low viscosity means good fluidity at low temperatures leading to easier start-up at cold ambient temperatures.
Mobil SHC Cibus 68 HT has been designed to have good heat transfer properties such as specific heat and high thermal conductivity that help provide rapid heat dissipation that can lead to increased efficiency of the whole system. Furthermore, the low volatility of Mobil SHC Cibus 68 HT can mean lower consumption.
Mobil SHC Cibus 68 HT is NSF H1 registered and accepted by the Canadian Food Inspection Agency and is therefore suitable for applications where incidental food contact may occur. Also, the Mobil SHC Cibus 68 HT is manufactured at ISO 22000 certified facilities that also meet the requirements of ISO 21469 helping to ensure that the highest levels product integrity are maintained. It is also suitable under Kosher (Parve) and Halal dietary law and is formulated to be free from nuts, gluten, wheat and animal products. It meets DIN 51522 heat transfer fluids requirements and testing.
Mobil SHC Cibus 68 HT is part of a wide range of NSF H1 registered lubricants from ExxonMobil for the food and beverage processing industry.
It is recommended that Mobil SHC Cibus 68 HT as well as other Mobil SHC lubricants should be stored inside and segregated from other non-H1 lubricants. Ideally, it should be stored in a clearly signed, separate, designated inside area. Drums and pails should not be stacked below or above other non-H1 lubricants. New packaging should be free from damage with an unbroken seal. Record the delivery date, batch number and expiration date. Record the date of initial seal breakage and use the contents in time by suitable stock rotation. Close all package openings after use. Do not replace unused oil in the container. Use clearly labeled, dedicated equipment for internal transportation. Label machinery with the name of the correct H1 lubricant where appropriate.
While Mobil SHC Cibus 68 HT may be physically compatible with other NSF H1 or non-NSF H1 registered mineral oil based heat transfer oils, a mixture may detract from its performance and also from its NSF registration status. Consequently it is recommended that before changing a system to Mobil SHC Cibus 68 HT, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits and to comply with NSF H1 registration.
Mobil SHC Cibus 68 HT is recommended for closed heating and cooling systems in a wide range of food processing applications where a NSF H1 registered fluid is required. These include meat, fish and beverage processing, ready-to-eat and convenience foods and animal food production. Further, this fluid is not recommended for use in open systems where hot oil is exposed directly to the air. If it sprays or escapes from leakage points, hot Mobil SHC Cibus 68 HT fluid may spontaneously ignite. In closed systems, maximum bulk operating temperature is 280°C with maximum skin temperature of 295°C. Maximum operating temperatures of the fluid are dependent on the duration of exposure to higher temperatures (which can vary due to the design of the system, flow rates, etc). Please consult your original equipment manufacturer to ensure proper operation. In addition, the following conditions are recommended:
1) Maintain turbulent flow through the heater with Reynolds number greater than 10,000;
2) take steps (as directed by heater OEM) to avoid localised areas of high heat flux, which can lead to locally high skin temperatures in the heater and shorten fluid life;
3) nitrogen blanketing to minimise exposure of the fluid to oxygen, which can lead to shorter fluid life.
Periodic used oil analysis and monitoring of Mobil SHC Cibus 68 HT in service is recommended to maximize its working life. An initial check of fluid condition is recommended one month after filling the system with Mobil SHC Cibus HT 68 and ongoing fluid analysis is recommended at six month intervals.
