18. Anti-condensation protection via operation line
The anti-condensation protection condensates the chamber humidity at the coldest point in order to avoid
the samples becoming wet from condensation. Anti-condensation protection is performed by the evaporator
and can be programmed On/Off via operation line “Anti-condensation” in Fixed value and program modes.
Use the anti-condensation protection only if absolutely necessary to prevent condensation on
the charging material.
When the anti-condensation protection is enabled the refrigeration machine keeps operating within warm-
ing-up phases (On = refrigeration machine operating, Off = refrigeration machine off).
• If possible, use the anti-condensation protection only during warm-up phases. If necessary it can
also be activated during hold phases.
• Do NOT use the anti-condensation protection above a temperature set-point of +20 °C / 68 °F
maximum.
To obtain optimal warming results without condensation on the samples, program a heating gradient of
approx. 0.5 °C/min.

Depending on size, material, and shape of the charging material and on the heating-up rate, condensation
may form despite the activated anti-condensation protection. This condensation is, however, reduced com-
pared to the state without anti-condensation protection.
