Unit 4Helitorch, Batchmixer and Modular Mix Transfer Components


Objectives l.jpg
Objectives

  • Know basic parts & mechanics of a Helitorch

  • Become familiar with the mixing systems


Slide3 l.jpg

Basic function of mixing system is to combine raw fuel with a gelling agent to create a thickened mixture, then transfer it to the helitorch
