I am an engineer we design and build compressors and package them. We process landfill gas. I need to specify a fire detection and surpression system for our packages and need some help. I need to know what the best media is to detect and supress a fire. We will have 1000SCF of gas in a vessel that is in a 150 gallon oil bath. The compreesor will be running at 3000SCFM and the will be a propane heater in the enclosure which is 10' X 2" X 12 Tall with various vents. The electrical is class 1 group D DIV 1. Any thoughts.
