Darui Electric recommends
The HRY2 sheath heater is made by inserting electric heating wires into an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, then shrinking the tube, and after heat treatment (some tubes do not require it), processing it into various shapes required by users. It has a simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids and acids, alkalis, and salts, and is also suitable for melting low-melting-point metals.
Technical Parameters:
Rated Voltage: Single-phase 220V, Three-phase 380V
Surface Heating Power: ≤0.7 W/cm² as design standard
Heat Transfer Temperature: ≤300°C
Working Medium: Minerals
Working Pressure: ≤0.8 MPa
