Notes:1. Insulation thickness is chosen either to prevent or minimize condensation on outside
jacket surface or to limit heat gain to 8 Btu/h·ft2, whichever thickness is greater.2. All thicknesses are in inches.3. Values do not include safety or aging factor. Actual operating conditions may vary.
Consult a design engineer for appropriate recommendation for your specific system.4. Data calculated using NAIMA 3E Plus program.
