According to Advanced RenewableEnergy Company LLC (ARC Energy) of Nashua, NH, USA, a provider of c-axis sapphire growth technologies and turnkey solutions for the LED solid-state lighting market, after qualifying sapphire substrates at multiple LED chip companies, China-based Jiangsu Trinity Material Co Ltd is continuing to further improve the efficiency of ARC Energy’s CHES (Controlled Heat Extraction System) furnaces. ARC is currently working on the upgrades to lower costs and increase equipment productivity.

With two factories (Jiangxi Trinity Material Co Ltd and Jiangsu Trinity Material Co Ltd), Trinity produces 2-8 inch sapphire ingots for LED chip manufacturing.

ARC says that its CHES furnaces allow seamless upgrades without investment in entirely new furnaces. The firm is currently working to further improve sapphire production costs by lowering consumable costs, reducing power consumption, and increasing equipment productivity. Its CHES upgrades are targeted to further reduce costs in mid-2013.
