Overview
The Galvatherm® flat immersion heater — A-mount with feet is designed to provide frost protection for storage tanks, with or without retention. Its flat profile and large heat-exchange surface enable simple, effective installation directly through an inspection hatch (minimum Ø 500 mm), including on a filled tank. Suitable for volumes sensitive to low temperatures and for autonomous frost protection.

Technical specifications

• Power: suitable up to 6 kW (application dependent).
• Frame materials: PP, PVDF, PFA-coated stainless steel or uncoated stainless steel.
• Feet: PP, PVDF, PTFE or stainless steel; standard foot height 50 mm.
• Heating cable: PFA-insulated cable mounted on a coated metal frame.
• Standard configurations: P30, P40, P90.

Key benefits

• Quick installation via inspection hatch (manhole Ø min. 500 mm) without emptying the tank.
• Support feet located on each side of the heating section for stable positioning at the tank bottom.
• Flat design allowing use in confined access situations while ensuring continuous frost protection.

Main applications

• Frost protection for storage tanks, with or without drip tray.
• Safety heating for temperature-sensitive fluids in food, chemical and environmental sectors.
• On-site use in winter conditions or in unheated buildings.

Safety and compliance

• Compliant with EN 60519-1/2.
• Optional: PFA-coated PT100 sensor factory-mounted directly on the immersion heater.
