Uniform temperature control
■ If the cover is opened, fan and heater will be stopped immediately to keep away
meeting inner air with outer air.
■ We use a cross type fan to make good uniformity.
Prevention against inner air leakage
■ To prevent against inner air leakage, external chamber is treated with heat
insulators and the open cover is stuck to the body unit with Packing.
■ To observe inside of chamber without opening the open cover, we are using a
translucent acrylic cover and setting a lamp up.
Programmed auto-run function
■ Our integrated controller allows controlling the inner circulating fan speed on
three steps. The 9-Step Programmed Control system can make to auto-run on
nine different temperatures and times (Max. 99hr. 59min.) and maximum 200
times for each time.
Safety device
■ Independent IC logic detects and intercepts electronic interference before the
main control board to give added safety to both user and product.
■ Built in Over Temp. protector warns (beep and LED lighted) and shuts off the
heater in the event of overheating problems.
