This is the sixth in our series of articles on walk-in coolers and freezers.
As seen throughout this article series, walk-ins are only as good as the components that are included in it. An important piece of the puzzle is the thermostat. A walk-in’s main job, not to put too fine a point on it, is to be cold. Maintaining the internal temperature is critical for meeting food safety standards and keeping product fresh for as long as possible. To do this, while also improving the energy efficiency of the system, a reliable thermostat is required.
