The system should be mounted on a movable bench with all refrigeration components clearly visible and controls are within easy access. Supply air is moved through a air ventilation duct which are made from polypropylene (PP) ducting covered with acrylic panels (plexiglass) to facilitate observations of the air condition in several monitoring points along the duct. All materials are corrosion resistant including all fasteners are stainless steel, industrial fan with plastic housing, and the humidification tank is made from stainless steel. The explanation of monitoring points in the ventilation duct and system electrical circuit are displayed on a colorful printed diagram for easy reference. Refrigeration lines are color coded to indicate the state of the refrigerant. Control panel with instrumentation including Line Voltage, Ampere (Total Current), Watt meter and Temperature and Humidity display panel meters are provided as a standard to control the trainer and to facilitate measurements. The unit comes with instruction manual and student job sheets.
