Starting with the essentials of nitrous oxide systems, bottle temperature plays a crucial role in system performance. When under 97 degrees Fahrenheit, nitrous oxide exists in both liquid and vapor states, with bottle temperature directly affecting system pressure and performance.

Bottle Basics and Pressure Relations

  • Bottle temperature under 97°F determines system pressure
  • Colder bottles (40°F) = lower pressure (520psi)
  • Optimal temperature range: 85-95°F (950-1000psi)
  • Above 97°F, nitrous enters supercritical state, reducing performance

System Performance Factors

  • Bottle heaters maintain optimal pressure (950-1000psi)
  • Cold bottles deliver less nitrous (up to 30% reduction)
  • Supercritical state (above 97°F) reduces system efficiency
  • Multiple bottles can improve consistency and performance
