Atlas Copco GA 26 VSD+ User Manual

• The water inlet temperature of the energy recovery system
• The water outlet temperature of the energy recovery system
Modifying settings
If the programmed warning settings for the water temperatures are exceeded, a warning
indication is shown on the controller:
Temperature input Minimum

Maximum
setting
Water inlet temperature of energy recovery ˚C 0 70 99
Water inlet temperature of energy recovery ˚F 32 158 210
Energy recovery water outlet temperature ˚C 0 90 99
Energy recovery water outlet temperature ˚F 32 194 210
To modify a setting, consult the relevant section in the description of the controller.
Recoverable energy
The recoverable energy can be calculated from:
RECOVERED ENERGY (kW) = 4.2 x water flow (l/s) x water temperature rise (˚C)
In the tables below, typical examples are given.
