CX Domestic Immersion Heaters were developed as high quality replacements for the most commonly used heater types. The CXC is available in a range of styles, including 2.5″ (64 mm) square flange with tinned copper sheath, 1″ (25 mm) tapered brass plug with copper sheath, 1″ (25 mm) non-tapered brass plug with copper sheath and round flange with zinc plated copper sheath. The CXI is available with a 2.5″ (64 mm) square flange with Incoloy® sheath. Elements are epoxy-coated to protect the heater from moisture and other contaminants that can lead to premature element failure.
