Packaged refrigeration unit (PRU) servicing requires primary knowledge of refrigeration and unit operation. This introductory course will help you gain, or refresh, that essential knowledge. We will begin with the standard features of a PRU and the uses of each type. Then we will examine each of the PRU components and how they operate together. Last, we will go through a basic inspection process and some common issues you will find.

In this series of simulations, you'll gain valuable experience when it comes to preventive maintenance on packaged refrigeration units. These procedures will ensure long equipment life, energy efficiency, as well as proper system performance. You'll have an opportunity to perform cleaning procedures, system performance checks, both electrical and temperatures and pressures, as well as leak detection. This course will get you thinking and acting like a pro when it comes to maintenance on packaged refrigeration units.

Apply your knowledge of Packaged Refrigeration Units (PRUs) in this course as you inspect, diagnose, and repair PRUs within a 3D simulation program. These simulations will demonstrate what you’d experience when encountering the 10 most common PRU failures. We’ll also cover the safety risks involved and important measures you must take to avoid them.

This is an assessment simulation, where you'll use the steps and skills you've learned and practiced on the Interplay platform to determine the fault and fix each scenario. Use the bottom tool bar to navigate around the environment, inspect components, access tools, and view diagrams. This is designed to mimic a real-world scenario, so there's no step by step guide giving you instructions for how to troubleshoot the scenario.

In this course on Packaged Terminal Air Conditioner (PTAC) Maintenance, we will explore the performed task of scheduled monthly and yearly preventive maintenance for PTAC units. With each scenario, you will be guided with realistic steps of identifying which scheduled maintenance is required during the different seasons as well as locating key components on the PTAC unit that requires maintenance. You will also be applying the procedural tasks needed for the monthly and yearly maintenance for the PTAC unit.

Have you ever wondered what it takes to get into painting? This may be the course for you. In this course you will be given an overview of painting basics followed by some safety tips. This course will also provide you with materials, tools and their function used for painting. You'll then be introduced to some painting techniques. Last you will learn about the steps in the painting process. We hope you enjoy the course!
