Software for calculating heat transfer for industrial furnaces and refrigeration technology

Heat transfer is the transfer of heat from a warmer substance in a gaseous or liquid state through a solid wall to a colder substance in a liquid or gaseous state. Heat transfer is made up of three processes. The heat transfer from the warmer substance to the wall surface, the heat conduction through the wall and the heat transfer from the wall surface to the colder substance.

The solution supports you perfectly and at the same time simply in calculating the heat loss of a stove wall or technical thermal insulation and in determining the temperature curve through the wall of a stove, which leads to the optimum design of the various wall layers.

Heat transfer according to:

• ASTM C680, EN ISO 12241, VDI 2055
• on vertical wall, ceiling, floor, cylinder, dome, fitting
• Diagram with max. 20 layers in color
• File temperature-dependent thermal conductivity values (30 in the standard version)

Advantages

• Extremely user-friendly and self-explanatory design
• Numerous information and safeguards against operating errors
• Selection of materials from the material list with headings
• Variants can be easily changed and saved
• Calculations can be saved in projects.

Features (excerpt)

• Results displayed as diagrams
• Output of the calculation as a table
• Export of calculations to writing systems
• Surface: flat wall, dome, fitting, cylinder (also internally cooled)
• Temperature-dependent thermal conductivity coefficients (also in H2-containing atmosphere)
• A factor and a surcharge for thermal bridges can be added to the thermal conductivity coefficients
• Heat transfer in a vacuum (radiation only)
• Internal heat transfer (hot side) calculated from: internal dimensions of the furnace, internal emissivity, convection, gas radiation from H2O, CO2, CH4

Not suitable for construction (heating and building construction).

• Additionally for net 420 EUR: File for over 1600 substances
• Alternative: Mini version: 4 layers without mat file net 570 EU

No training is required. The program does not require any special hardware requirements or third-party programs.
