Profile: TechEng Designs is engaged in developing technical and engineering software. Tank Heat Loss & Insulation calculations will automatically calculate cylindrical tank surface area, bare tank heat loss, insulated tank heat loss, optimum insulation thickness, and do simple payback calculations for most tanks including heads. Also flat bottom tanks. Records data for each tank and most types of heads in a report. Program uses both basic English and basic metric units. We deal with stack gas emissions that standardize contaminates in the exhaust gas from incinerators. Our tank capacity calculations automatically calculates volume for any increment of depth from empty to full tank.
