The Drop-In Round Heated Well from Hatco keeps a wide range of hot and fresh foods at safe serving temperatures. It features self-adjusting thermostats that monitor the actual temperature of the well and provide heat only when necessary. The HWB-xxQTD models come with a drain. It also has a separate lighted On/Off rocker switch and a temperature dial, enabling consistent temperature control. The 50% larger drain with a flat screen makes cleaning easier and helps keep pans level.
