1, and this equipment outside box is cold-rolled plate, and surface used electrostatic spray plastic process, and within bile for stainless steel, and insulation layer by poly ammonia fat sent bubble formed, light window used double glass to ensure box within of insulation performance (cryogenic training box and BOD, requirements not light of training box no Windows), box internal has cold, and heat Fan Road makes box within gas cycle smooth, and temperature more uniform.

2, equipment, temperature control systems, intelligent application of advanced electronic circuits, analog control. Self-tuning PID system, heating system with "zero" no touch point switching circuit techniques, resulting in a pulse-width-modulated heating, so that the temperature control range is less than or equal to 1.
