Freezing Point Test Apparatus
Phoenix India Solutions offers a reliable Freezing Point Test Apparatus for accurate determination of the freezing point of aviation fuels and petroleum products as per ASTM D1177. The apparatus features mechanically refrigerated cascade cooling, double-stage cooling with double compressors, microprocessor-based PID temperature control and operation down to -55°C.
Test Method
The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals that can restrict the flow of fuel. The temperature of the fuel in an aircraft tank normally falls during flight depending upon aircraft speed, altitude and flight duration. The test determines the temperature below which solid hydrocarbon crystals form in aviation fuels. The sample is cooled with continuous stirring in a dewar-type sample tube until crystals appear.
Construction
- Double-walled, thermally insulated construction for continuous operation.
- Powder-coated external surface for aesthetic appearance.
- Drain, overflow and fill valve provided.
