This solar energy producer uses hot oil and heat exchangers to heat various process materials in the manufacture of polysilicon for solar applications. The company’s large, gas fired hot-oil system, however, did not meet new state emission standards. Upgrading to low-emission gas burners was not an option, however, due to high costs and impact on production. With the state deadline to comply with the new emission standards looming, the manufacturer was pressed to find a solution quickly. - The Chromalox NWHO circulation heater – a zero-emissions electric heater solution to replace gas-fired systems – offered the perfect solution. The 7.5 megawatt hot-oil circulation heater was paired with a SCR control panel to create acomplete heat transfer system.
