While the driving force is measured with a relatively high resolution, the overall heat transfer coefficient or the calibration factor respectively, is determined by means of calibration before and after the reaction takes place.

In comparison with static and dynamic ice storage systems, the overall heat transfer coefficient ( OHTC ) during the production of pumpable ice is more than tens or hundreds of times higher ( more efficient ) than the same coefficient for the above-mentioned TESS types.

After the heat transfer coefficients ( h _ { i } and h _ { o } ) are determined, and knowing the resistance due to fouling and thermal conductivity of the boundary material ( k _ { w } ), the Overall Heat Transfer coefficient ( U _ { o } ) can be calculated.
