Chromalox AR-518 Industrial Temperature Controller

Chromalox AR-518 Industrial Temperature Controller is a dedicated control device designed for industrial heating applications. This model operates from a 277 V supply and handles loads up to 30 A, making it suitable for medium-power heating equipment in commercial and industrial settings. The AR-518 provides temperature control across the 200-55F range, enabling precise setpoint management within that interval. Built by Chromalox, a long-standing name in industrial temperature controls, the AR-518 is intended for integration into control panels or equipment where reliable, fixed-point thermal regulation is required. With its 277 V input and 30 A output capability, this unit is designed to drive resistive or similar loads used in industrial heating processes that require standard industrial voltages. The AR-518 designation identifies this specific controller within Chromalox's legacy product lineup for temperature control tasks.
