FREEZING POINT APPARATUS - WITH IN-BUILT REFRIGERATION SYSTEM UPTO (-70 °C) - (ASTM  D1177, ASTM D2386)-

FREEZING POINT APPARATUS - (-70 °C) - (ASTM D1177, ASTM D2386)-

Model Number : EIE-PTLT-143R70

This test is particularly relevant for aviation fuels (e.g., jet fuel) where low-temperature performance is critical for safety and engine operation. As per ASTM D2386 ‑ IP 16 ‑ NFM 07048 ‑ ISO 3013 ‑ DIN 51421. The entire instrument assembly Consists of Unsilvered vacuum flask, Jacketed sample tube, Brass packing gland, Motorized stirrer, Stopper, Clamps, Refrigerated water-bath and Stand. Temperature range from -70°C to 0°C


Compliance with International Standards

This equipment complies with the following international standards, ensuring precise and reliable performance:

  1. ASTM D2386
  2. IP 16
  3. NFM 0704
  4. ISO 301
  5. DIN 51421

Purpose

This standard outlines a method for determining the temperature at which solid hydrocarbon crystals form in turbine and reciprocating engine fuels under cooling conditions. These conditions may occur during flight or while on an airfield, making this test critical for aviation safety and fuel reliability.

Complete Instrument Assembly

The instrument assembly is supplied with the following high-quality parts and accessories:

  1. Unsilvered Vacuum Flask: Approximately 10-liter capacity for effective insulation and temperature control.
  2. Jacketed Sample Tube: Ensures accurate temperature measurement and sample integrity.
  3. Brass Packing Gland: Provides secure sealing of the sample tube.
  4. Motorized Stirrer: Facilitates uniform cooling and mixing of the sample.
  5. Stopper and Clamps: For secure and safe operation.
  6. Refrigerated Water-Bath: Enables precise temperature control within the range of 0°C to -70°C.
  7. Stand: Provides stability and support for the entire assembly.

Important Note

For cooling, the operator must supply suitable cooling mediums, such as acetone or alcohols (methyl, ethyl, or isopropyl). These substances require careful handling due to their flammability and volatility. Liquid nitrogen may also be used as a coolant for achieving extremely low temperatures.
