. An advanced cold balance control mode and PID control technique, substantially reducing energy consumptions of the machine;

. After programmable execution ends，the machine goes back to its normal temperature automatically in order to protect specimens;

. A unique air circulation design is adopted to ensure no droplets can be generated on the top of the operating room even in hot and humid mode;

. The machine is provided with a good airtightness performance,ensuring that no frost forms on the machine during long-time operation (1,000 hours above);

. A smart output quantity control mode is adopted to avoid frequent start and stop of the compressor, which effectively extends its service life;

. Running with frost, and frost-free running.
