LFD does not require special ambient conditions, but it does need a controlled working environment to be effective and safe. The site must provide stable power for high current, good grounding, and protection from rain and dust. Ambient temperature mainly affects heat losses, not the process itself. More important are tightness of the tank, ability to maintain deep vacuum, and reliable temperature monitoring, because drying efficiency depends much more on vacuum quality and insulation heating control than on external climate.
