ELECTRIC STORAGE TANK HEATERS / OCH Series
OPEN COIL HEATERS
The OCH (open coil heater) series of elements consists of helical wound nickel chromium resistance wires supported by interlocking ceramic insulators. The ceramic insulators are mounted on a flexible stainless steel strap which allows the element to be bent to an 18” radius. These flexible elements are available in two sizes and are designed to be inserted into standard 2” or 3” sch. 40 or sch. 80 closed pipe wells.
