Heat-up only (P = m × c × ΔT ÷ t). Processes that also need to hold temperature, melt/evaporate material or heat a continuous flow need extra power — our engineers can size it for you.

The energy needed to raise a material's temperature is mass × specific heat × temperature rise. Dividing by the heat-up time gives the power, and a safety margin covers losses to the surroundings.
This covers heat-up only. Holding temperature, melting, evaporation or continuous flow heating need additional power — share your process with us and we'll size it.
Results are engineering estimates for initial sizing. Final heater design should be confirmed with our application engineers.
