Photovoltaic Solar Cells

The capability of a solar panel to convert solar energy into electricity is only as good as the quality of the panel. Precision manufacturing processes are required to ensure each step is closely managed and controlled. Chromalox’s Component Technologies ensure your quality requirements are met across all process steps from amorphous cell and PV module production, to deposition and lamination.

Concentrated Solar Plants

Concentrated Solar Plants (CSP) utilize large reflectors or mirrors to direct and concentrate the suns rays onto an absorber pipe that contains a heat transfer medium comprised typically of molten salts or heat transfer oils. The pipes that carry the heated medium must travel great distances from the source of the reflectors to the processing side of the plant. Chromalox high temperature inline heaters, tank heaters, and heat tracing products are ideal for ensuring heat transfer mediums are kept above critical temperatures, both in transportation and storage.


Circulation heaters operate as an electric heat exchanger by directly heating the process media in an in-line configuration. Units operate at nearly 100% efficiency and offer a compact heating solution. A wide selection of materials is available such as copper, carbon steel, stainless steel, or INCOLOY®. Moisture and explosion-proof terminal enclosures along with ASME, PED, KOSHA, and SELO are also options. Click here to visit catalog


Steam Boilers

Units provide steam for any process need using a compact, flameless package. Ready-to-install units require only water and electric power supplies for zero-emissions operation. Carbon or stainless steel construction to UL, CSA, ASME, and PED codes. Click here to visit catalog


Duct Heaters

Available with power ratings up to several megawatts and capable of producing temperatures up to 1,200°F (650°C) for heating air or other gases. Tubular, finned tubular, and finned strip elements outperform gas, oil, and open coil electric units in both heating efficiency and safety. Click here to visit catalog



Immersion heaters can be installed directly in process media such as water, oil, solvents, viscous solutions, and gas streams. Units operate at nearly 100% efficiency and offer a compact heating solution. Common heater installation methods are flanged, threaded, or over-the-side designs, with a wide selection of materials such as copper, carbon steel, stainless steel, or INCOLOY®. Moisture- and explosion-proof terminal enclosures along with IEC, ATEX, and CSA are also options Click here to visit catalog
