444 Rack Tech Program

Rack Tech Program  (2 Courses / 35 Instructional hours )

By Bob Feathers

The Rack Tech Program is an advanced program totaling 35 instructional hours. Students will take one course at a time in a systematic progression that moves through market refrigeration and the specific technologies focusing on Parallel and Unparallel Rack Systems and Applications as well as video demonstrations of compressor teardowns.

The need for Refrigeration Mechanics is ever evolving:

• Old systems still need to be maintained.
• Retrofit opportunities.
• New technologies and refrigerant requirements.
• System controls / Energy savings.
• Food safety and monitoring are very important. 

Students are enrolled as online asynchronous independent study. This access allows students to login at their convenience 24/7/365. This program is NATE recognized for 35 hours of continuing education (CEHs) which are applicable to NATE re-certification.

Prerequisites: This advanced program is designed for HVACR technicians, facilities managers, and commercial maintenance technicians who have already completed an educational program for HVACR and/or have current industry work experience in the field. The program will build on your existing knowledge of HVACR fundamentals and equipment and help you learn commercial supermarket applications and systems.

245 Compressor Failure Analysis with Bob Feathers (Mr. Compressor)  

By Bob Feathers and Chris Compton.

This is a 11 video / 5-hour series of compressor tear downs performed by and commented on by Bob Feathers, "Mr. Compressor".

He dissects a range of manufacturer's reciprocating semi hermetic commercial compressors that have failed and points out the clues that point to the reason for failure.

"A Compressor Doesn't Fail, A System Fails!" - Chris Compton

Prerequisites: Because of the advanced topics discussed in this video series, it is recommended that you complete these refrigeration courses: 141 HVACR Refrigeration I, 142 HVACR Refrigeration II, 441 HVACR Commercial Refrigeration I, 442 HVACR Commercial Refrigeration II; or have extensive experience in these topics. This course is recognized for 5 hours of continuing education (CEHs) applicable to NATE re-certification.
