Made from stainless steel,durable used; Inclined control panel; easy operation; Mirco-computer can contrl heating,heat preservation; LED digital tube and light, indicate the status of equipment; PID temperature-controlled function, can modify the control indicate to prevent the temperature,precision of temperature controlled:±0.5℃; Adding water when water lack, when reach the normal water level, continue heating when adding water; Gravity exhaust design, effect stable; The airproof ring made of silicon rubber is not only durable but also with better result; Over temperature(set temperature +2℃) stop heating and alarm; Over pressure to 0.23Mpa, safety valve open and push the steam; Offer interface for explosion proof bag; Water spraying can be fast for cooling process, it only take 0-10min to make temperature from 135% to room temperature; Anti-air pressure auxiliary device can be choosed; Imrpove the disadvantage for breaking bag during sterilized process; Drain valve can push the water in container, prevent bilge; Muti-direction of wheel with brake,easy moving and position; Immerge electric heating tube, heat efficiency is better.
