• Over Current Protection
• Terminal Box Isolators
• On/Off Status
• Temperature Sensor & Control

Finned Tubular Heating Elements:

SPC’s finned tubular elements help reduce watt density and hot spots, which allow for a more consistent airflow stream within the duct. Custom-built for specific job specifications, the finned tube heating elements are available in two standards with metal sheath diameters of 8 mm and 11 mm and consist of a unique nickel-chromium heating element and a stainless metal sheath. In order to ensure the best heat transfer and enhanced heat transfer area and rate, SPC utilises only high-purity magnesium oxide and corrugated stainless steel spiral fins.

Open Coil Heating Elements:

SPC’s open coil heating elements get their name due to the fact that the coils are exposed to surrounding air, which allows for rapid heating and cooling and consist of a series of resistance wires formed into coils. Meticulously designed from austenitic nickel-chromium alloy (NiCr alloy) for use at temperatures up to 1200°C (2190°F), the coils boast great ductility after use and excellent weldability with the alloy known for its high resistivity, good oxidation resistance and form stability.
