Petroleum Distillation Apparatus

The design of the Koehler Automatic Atmospheric Distillation Tester uses the most advanced international design concepts and test methods to improve the degree of automation of the distillation unit, guarantee the accuracy of measurement, and minimize the potential for operator error.

The sample is evaporated and condensed under controlled conditions, and observations are made of the temperatures at which various percentages are recovered and/or the percentages recovered at specific temperatures. The Koehler Atmospheric Distillation Tester is designed to perform optimal distillation analyses of gasolines, kerosene, diesels, organic solvents, and benzene products to ensure conformity to rigid quality control standards. The tester automatically performs distillation testing, stores result data internally, and allows for data exportation through multiple functions.

An advanced model is available (K45750-DP) with automated machine-vision dry-point detection. This feature replaces manual observation by automatically identifying the dry point and recording synchronized video images, enabling efficient review, improved consistency, and complete traceability.

FEATURES:
• Conforms to the specifications of: ASTM D86, D850, D1078, EN ISO 3405, IP123 and 195, DIN 51 751, NF M07-002, GB/T 6536, and GB/T 3146.1
• One–button start function executes completely automatic sample distillation testing
• Flask positioning function eliminates uncertain factors caused by positioning errors
• Automatic fire extinguishing system, dual flame detection, and automatic fire extinguishing function
• High-efficiency compressor cold circulation system provides high speed cooling, improving efficiency and shortening measurement interval time.
