Product Details
Main Characteristics
Adopted European MOSFET, IGBT solid state power module and advanced inverter technology.
It has the function of three-stage time setting represented by heating-heat preservation-cooling. Furthermore. The power for heating and heating preservation is available for independent regulation, which can be effective to some extent control the heating curve and the heating temperature.
Fully functional, include over-current ,over voltage, water shortage , lack of phase and other fault state protection and display, which can provide higher reliability and durability.
Low voltage output does not present safety hazard.
The comprehensive full load design is available for 24-hour continuous operation.
