IRTC’s own instructor, Zach, spoke at the Blue Ridge Chapter’s Western Virginia Expo on Thursday! His presentation topic was “Hands-On: Setting Hand Expansion Valves.”

“We looked at the three main applications of hand expansion valves in refrigeration systems (expansion, minimum flow, and metering for recirculated evaporators),” Zach said. “We quickly reviewed enthalpy (P-h) diagrams to explain why these applications are different, and how the correct setpoints could be calculated using engineering data. We then kicked on the system, and explored checking the setpoint, and different practical approaches to setting them that don’t involve calculations.”

Looking to expand your knowledge on CO2 refrigeration? Look no further!

The CO2 Refrigeration course is recommended for anyone already working with CO2 refrigeration systems, looking for more information on CO2 refrigeration systems or that has attended our refrigeration classes (Ammonia Refrigeration, Operator I or SOP).

This class provides a thorough understanding of CO2 refrigeration systems. Participants learn about specific properties of CO2, safety, design, installation and maintenance.

Come by and see us at the Blue Ridge Chapter's Western Virginia Expo Day! We'll be here from 8-5 at 373 Mt. Torrey Road, Lyndhurst.

This week, IRTC is training on Standard Operating Procedures (SOP's), Mechanical Integrity Inspections, Process Safety Management (PSM)/Risk Management Program regulation requirements, and ammonia industry codes and standards.

We provide hands-on training with our fully operational ammonia refrigeration system.

This includes: initial startup, normal operations, temporary operations, emergency shutdown, emergency operations, normal shutdown, safe work practices, equipment and more.
