Also known as foil heaters, these bend around tank corners and edges without damaging the heating element. They permanently adhere to container surfaces to heat contents without direct contact. Heaters require a temperature switch or controller (sold separately) to regulate heat output.

Note: Do not cut or overlap these heaters—this will damage the heating element. Use a roller during installation to remove air pockets and ensure direct surface contact. Once heaters have been applied to a surface, they cannot be removed and reused.
