Uses of HRY1/HRY2/HRY3 Sheathed Heaters:
SRY2 and SRY3 tubular electric heaters are used for heating oil in open or closed oil tanks. SRY4 tubular electric heating components are used for heating flowing or circulating oil. Due to the high surface load of this model, it is only suitable for oil with good heat transfer effect. HRY1/HRY2/HRY3 sheathed heaters are suitable for heating air, oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low-melting-point alloys. They feature high thermal efficiency, long service life, high mechanical strength, easy installation, safety, and reliability.
