Carrier 30RBM 330 - Brine Solution Options for Low;Medium Temperatures

54
12.2.6 - 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.
Production of brine solution from 0°C to -15°C is only possible
with the 6B low-temperature brine solution.
The unit is equipped with insulation on the intake tubes. 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).
