Jet A-1 is a kerosene-grade fuel suitable for most turbine-engine aircraft. Jet A1 technical specifications include  a minimum flash point of 38 degrees C (100°F) , a maximum freezing point of -47°C, a density range of 775-840 kg/m³, and typically adheres to international standards like ASTM D1655 (US) and DEF STAN 91-91 (UK), signifying its suitability for most jet aircraft with a kerosene-type composition; it is considered the most widely used aviation fuel globally. 

Trusted by aviation professionals worldwide, our aviation fuels ensure the highest quality and performance standards for both commercial and private air travel. We offer Jet Fuel A1, known for its reliability and compliance with international safety standards, as well as Kerosene, which is used for both aviation and various industrial applications. Together, these fuels power aircraft across the globe, ensuring safe and efficient operations.

Key points about Jet A1 specifications:
  • Freezing Point: Maximum of -47°C, allowing operation in colder climates compared to standard Jet A fuel (-40°C). 
  • Flash Point: Minimum of 38°C, ensuring safety during handling and storage. 
  • Density: Typically between 775 and 840 kg/m³ 
  • Relevant Standards: Complies with ASTM D1655 (American) and DEF STAN 91-91 (British).
