Heating schemes
System uses silicone rubber heater, and heat insulation cover for heat preservation outside. To keep uniform temperature of the cylinder, it' s divided into three sections: upper, middle and lower;

RDB type heater can be used for pipe, silicone rubber tanks, cabinet put oneself in another's position of heating and heat, box. This heater has features as following:

(1)heating fast and even, high thermal efficiency, long service life;

(2)Moisture-proof silicone rubber and alkali-free glass fiber double make the heater with more reliable insulativity;

(3)Aluminum plate assist heating and cooling, improve heater' s thermal efficiency and prolong its service life.

(4)Good appearance, easy installation;
