12.2.5 - Brine option (Options 5B and 6B)
The 5B medium-temperature brine solution option is used to
produce low temperature chilled water down to 0°C.
Brine production from 0°C to -15°C is only possible with the
low-temperature brine solution option (6B).
The unit is equipped with insulation on the suction pipes. The
insulation is reinforced on the low-temperature brine solution
option.
The operating range depends on:
• the size of the unit,
• the glycol type,
• its concentration,
• the ow rate,
• the temperature of the glycol solution,
• the condensation pressure (ambient temperature).
