INTRODUCTION

Hatco Refrigerated Drop-In Wells are specially designed to hold
cold foods at safe serving temperatures. The insulated, top­mount units are available in one through six pan configurations.
A unique top bezel design allows cold air to effectively blanket
the food product inside the refrigerated well. In addition, the
bezel design provides clear viewing and easy access to the
food contents of the refrigerated well.

All models are equipped with a condensing unit that can be
rotated to accommodate the installation location. The
condensing units on the three largest models also can be
moved between the center of the units and the evaporator coil
connections for additional installation flexibility. One year parts
and on-site labor warranty is standard.

Hatco Refrigerated Drop-In Wells are a product of extensive
research and field testing. The materials used were selected for
maximum durability, attractive appearance, and optimum
performance. Every unit is inspected and tested thoroughly prior
to shipment.
