8.1 Ethylene Glycol Solutions
Water and ethylene glycol solutions used as a thermal vector in the place of water reduce the performance
of the unit. Multiply the performance figures by the values given in the following table.

Note:
1. During winter leaving the unit unused, please drain water out completely from unit if no antifreeze were
charged into pipeline, or keep power on (at standby or off status) and ensure that water is contained
inside of unit.
2. When ambient temperature lower 5 ,℃ running cooling mode must be charged antifreeze. Refer to
upper parameters for the charged volume.
8.2 Fouling Factors
The performance data given refer to conditions with clean evaporator plates (fouling factor=1). For different
fouling factors, multiply the figures in the performance tables by the coefficient given in the following table.
