National Mechanical Insulation Committee Energy Calculator Shows Savings
Is its Mechanical Insulation Design Guide, the National Mechanical Insulation Committee(NMIC) presents a calculator that estimates the performance of an insulated horizontal piping system given the operating temperature, the ambient temperature, and other details about the system.
Sample results show drastic drops in heat loss and tremendous savings with payback of installation costs in as little as 5 months.
