Overview
This Supermarket learning program was designed for refrigeration professionals (technicians) who have field experience and don't want to be stressing on jobsites anymore. This is a continuing education program to grow your knowledge on installations, servicing and troubleshooting different supermarket refrigeration systems. The program will improve your knowledge, competency and confidence when working on parallel racks, secondary systems, cascade systems as well as medium and low temperature condensing units.
Do you want to look like a Rockstar in front of your customers, coworkers or boss? Any technician who completes this in depth learning program will have the tools and resources to figure out what system issues they are looking at and resolve them fast and effectively.
I created this learning program from the years of supermarket and commercial field experience and knowledge pass down to me from subject matter experts. If you are looking to become the top technician at your company this course will help you get there.
4-week Supermarket Learning Program
Learning modules will consist of 3 major activities with measurable goals to keep you on track:
1. Each week a 2 hour online instructor led training with interactive work, polls, and quizzes
2. Assignments with on-the-job practical learning
3. Knowledge assessments and Q&As to solidify previous modules
Every module will finish with a knowledge assessment and an assignment.
*This leaning program is not is a controls course. We may bring up some different facility controllers examples in conversation and we may discuss things to look for when trying to solve a problem.
Module 3: Low Pressure Components
Module 2: High Pressure Components
Module 4: Service and Troubleshooting
Module 1: Commercial System Designs
Certification
To earn a certificate of completion of the 4-week Supermarket learning program, the refrigeration professional must finish their quizzes, assignments, and the final knowledge assessment. Following completion of the virtual program, they will receive a certificate from Refrigeration Mentor.
