Data with water at 10°C.
In the case of using glycol, apply the correcting factors indicated in Fig. 5 and 6 of the Selection Guide section.
Table 9. Correcting factors for other glycol concentrations
If it is necessary to select different glycol percentages, correct the capacity and absorbed power capacities of tables 2 and 4 (35% ethylene glycol),
multiplying them by the coefficients indicated in table 9.
