Components:
LCD program controller
--99 cycles can be preset, 30 segments can be programmed, each segment has a setting time of 1~9999min (hours)
International brand compressor
Environmentally friendly fluorine-free refrigerant R134A
Independently developed water circulation system
--Double built-in water tanks, the auxiliary water tank enters the main water tank after preheating to prevent cold water from being pumped directly into the tank and affecting temperature and humidity fluctuations in the tank
--An additional external water storage tank with water shortage alarm can be used for one month at 25℃ and 60%RH after filling up.
