12 - OPTIONS
12.2.6 - Brine option (Option 6B)
Brine production from 5°C to -8 °C is only possible with the
low-temperature brine solution option (6B).
The unit is equipped with insulation on the intake tubes.
The insulation is reinforced on the low-temperature brine solution
option.
Operating range
■ Low water temperature brine solution (ethylene glycol or propylene glycol)

Leaving water temperature (°C)
1. Water type heat exchanger ∆T = 5K.
2. The hydraulic and/or water type heat exchanger module must be must be
protected against frost (option 41 or 42A or 42B) or the loop must be protected
by an antifreeze solution for outdoor temperatures < 0 °C.
3. These ranges are guidelines only. Verify the operating range with the electronic
catalogue.

The operating range is based on:
■ The size of the machine,
■ The type of glycol,
■ Its concentration,
■ The flow rate,
■ The temperature of the glycol solution,
■ The condensing pressure (ambient temperature).
