This unique, high-value, diagnostics-centered training event for the heavy duty and
off-road vehicle A/C technician will take place on Friday, May 29, 2015 from 8:00am to 3:00pm CDT at T/CCI’ s climatic wind tunnel facility in Decatur, IL.

Daniel Spurgeon from Caterpillar will cover the following topics focusing on service for CAT vehicles:

  • Review importance of pulling a deep vacuum
  • Refrigerant recovery, system evacuation, and recharge procedure
  • Leak detection importance; comparison of different methods
  • Review conditioner groups from several machine products (plan to have several units on display)
  • Review of individual system components and their function (dryers, accumulators, expansion devices, etc…) and more.

T/CCI will also hold tours and demonstrations utilizing their state-of-the-art climatic wind tunnel facility and present valuable service information in a dynamic presentation called, Climatic Wind Tunnel: “Let’s Test It!” This unique service demonstration will cover:


  • T/CCI will demonstrate a real charge determination of a “normal” passenger vehicle and have direct interaction with the members including allowing them to plot pressure temperatures, superheat and sub-cooling.


  • T/CCI using the same vehicle and climatic wind tunnel will continue the charge determination into an “overcharged” condition to demonstrate the effect on not properly compensating for residual oil in the system.


  • T/CCI will then pull charge and oil from the same system which will dramatically show the effect of reduced refrigerant and oil charge.


  • T/CCI will facilitate the walk-through of the climatic wind tunnel to demonstrate severe cooling conditions.


“MACS is grateful to both CAT and T/CCI for making this unique training opportunity available so MACS can offer it to the greater mobile A/C industry,” commented Elvis L. Hoffpauir, MACS president and chief operating officer. “Any technician who participates in this training clinic will enjoy a unique learning opportunity that will be invaluable to their diagnostic knowledge.”


Registration for MACS members is $75 and $125 for non-members. Register now at or call 215/631-7020 x 306.
