Description
Description
The Submersible Tank Heater provides a simple and reliable solution for heating hydraulic oil, lubrication fluids and other industrial liquids directly inside tanks and containers. By transferring heat directly into the liquid, it helps maintain stable temperatures, reduce viscosity and support efficient equipment performance in cold or low-temperature conditions.
Designed for quick installation, the heater features an integrated magnetic mounting system that allows it to be positioned securely at the bottom of the tank without tools, permanent fixing or modification to the container. This makes it particularly suitable for retrofit applications where a straightforward heating solution is required.
Constructed from durable AISI 304 stainless steel and incorporating a ceramic heating element, the heater is designed for reliable operation in demanding industrial environments. With an IP68 protection rating, it is suitable for direct immersion when correctly installed.
The heater is available in 250W, 500W and 1000W versions, with 230V AC or 24V options, providing flexibility for different tank sizes and applications. Fixed temperature cut-off options, such as 20°C or 40°C, are available for basic temperature maintenance and frost protection.
