Witeg – Personal-Type Laboratory Freezer (WUF-25 )

Ideal for:

  • ultra-low refrigeration

Safety mechanism:

  • built-in standard warning and alarm functions


  • digital feedback controller

UniFreezeTM system:

Single compressor ensures temperatures down to -86°C, minimized power consumption, and minimized noise level.

RoHS certified:

No hazardous substances (Pb, Cd, Hg, Hex-Cr, PBB, PBDE) are used in all UniFreezeTM and DuoFreezeTM freezers!

Natural refrigerants:

Instead of using HFC refrigerants (R-134a, R-404A, R-507) all UniFreezeTM and DuoFreezeTM models have a specially mixed refrigerant mostly consisting of natural materials.

Power consumption:

Up to 39% lower than the average competitor.

Devices with 230 V power supply can also be supplied with 120 V on request.
