❑ If -10°C < T amb. < 0°C heaters and pumps are switchedON by the electronic control.

❑ If -20°C < T amb. < -10°C in addition to the anti-freezeheaters, it is necessary to double insulate tanks and pumps(special machine).

❑ If outlet water temperature Tw out <+5°C it is necessaryto use antifreeze mixtures.

Antifreezing heaters option

Features

❑ Availability: mod.015-351

❑ hot gas bypass solenoid valve (mod. 015-051) or electronic expansion valve (081-351)

❑ shut-off valves for hot gas bypass (TAEevo031-351)

The valve keeps the temperature of the process water at the unit outlet constant and within narrow tolerances (precision ±0.5°C) by injecting hot gas into the evaporator.

❑ High precision PID control

❑ Control of outlet temperature independent of compressor minimum ON/OFF times

Close temperature control – LASER version

Features

Advantages

Suitable for ambient temperature down to -20°C:

❑ For operation without glycol the “Antifreeze heaters option” must also be specified.
