The Vollrath/Idea-Medalie 59843 Quartz Heater is a 400W, 60V heating element supplied as a convenient 2-pack, designed for use in compatible warming equipment. It works by passing electrical current through a quartz-encased filament, generating infrared heat that is quickly transferred to the surrounding area without excessive warm-up time. This direct radiant heat helps maintain even temperatures for food holding and display. Its compact and durable design supports reliable operation, while the two-pack format allows for easy replacement, helping reduce downtime and ensure consistent performance in commercial foodservice environments.
