Description
The 26-4937S submersible oil heater is designed to directly heat hydraulic oil and other industrial liquids in compatible tanks and containers. Direct heat transfer helps maintain the fluid temperature and limit its increase in viscosity under low-temperature conditions.
The AISI 304 stainless steel structure incorporates a ceramic heating element. The magnetic mounting system allows the device to be positioned on the bottom of the tank without requiring permanent installation or modifications to the container.
The 26-4937S version operates at 24 V and features fixed-threshold thermal control: it switches on at 12 °C ±3 °C and switches off when it reaches 20 °C. It is suitable for temperature maintenance and frost protection in compatible industrial applications.
