Portable SRY6-1, 2, 3 Sheathed Electric Heater Product Introduction
The electric heater is connected to the oil tank body by flange. The sheath isolates the heating core from the heated oil. When replacing the electric heater, there is no need to drain the oil from the tank; just pull out the heating core and replace it with a new one, making maintenance convenient.
The electric heater has a large contact area with the heated oil, low surface power, no carbon deposition, and the oil will not be locally overheated and carbonized. Long service life, safe and reliable.
The heating tube 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 excellent thermal conductivity and insulation, then shrinking the tube, and after heat treatment (some tubes do not require it), processing into various shapes required by the user. It has simple structure, high thermal efficiency, good mechanical strength, and excellent adaptability to harsh environments. It can be used for heating various liquids and acid-base salts, and also adapts to heating and melting low-melting-point metals.
Scope of application of tubular heaters: Suitable for heating oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low-melting-point alloys. It has characteristics such as high thermal efficiency, long service life, high mechanical strength, convenient installation, and safety and reliability.

Features:
The electric heater consists of a heating core and a sheath. The heating core uses high-temperature resistant alloy electric heating wire as the heat source, high-temperature resistant ceramic as the insulation medium, and the sheath is made of cold-drawn seamless steel tube or stainless steel.
The electric heater is connected to the oil tank body by flange. The sheath isolates the heating core from the heated oil. When replacing the electric heater, there is no need to drain the oil from the tank; just pull out the heating core and replace it with a new one, making maintenance convenient.
The electric heater has a large contact area with the heated oil, low surface power, no carbon deposition, and the oil will not be locally overheated and carbonized. Long service life, safe and reliable.
