    Walk-in coolers: temperature controls

    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.

    Walk-in coolers: thermostatic expansion valves and solenoid valves

    This is the fifth in our series of articles on walk-in coolers and freezers.

    As with any refrigeration system, controlling the flow of refrigerant is vital in making a walk-in cooler or freezer operate properly. Two of the most common types of refrigerant control valves are thermostatic expansion valves and solenoid valves.

    This is the fourth in our series of articles on walk-in coolers and freezers.

    As seen in the previous articles in this series, each component of a walk-in cooler or freezer plays a vital role in ensuring optimal performance. In this article, we will examine how regulating small aspects of a walk-in’s refrigeration system, like fan speed, can have a major impact on performance.
