■ Double shell design for low external cabinet temperature with energy saving
■ Special inside construction design for exceptional Temperature Uniformity
■ Use high quality of insulation for variable heat-up rate (fast heat up and cool down rate) and resistance to thermal shock.
■ Cooling fans move air between inner and out chamber case to reduce exterior shell temperature and improve energy efficiency and operator safety
■ Safety door switch interrupts power to heating elements when door is opened ; protect elements & insulation and minimizes exposure to operator
