Evaporator Waterside (not for free-cooling version)

Figure 8 – Glycol percentage recommendation curve

1 = Critical risks of freezing
2 = Efficient freeze protection
3 = Ethylene glycol
4 =  Propylene glycol
% = Glycol percentage (mass concentration)
°C = Glycol or water temperature

CAUTION!

1.  Additional glycol beyond the recommendations will adversely affect unit performance. The unit efficiency will be 

reduced and the saturated evaporator temperature will be reduced. For some operating conditions this effect can 
be significant.

2.  If additional glycol is used, then use the actual % glycol to establish the low refrigerant cutout set point with Trane 

service advice.

3.  The minimum low refrigerant cutout set point allowed is - 20.6°C. This minimum is established by the solubility 

limits of the oil in the refrigerant.

4.  With glycol application, ensure that there is no fluctuation of brine flow versus Order Write Up value, as a 

reduction of flow will adversely affect unit performance and behavior.

5.  Full unit simulation is required for proper prediction of unit performance for specific operating conditions. 

For information on specific conditions, contact Trane.
