QTM 320 Quantum HD Unity Compressor Controller II

Marketplace Course Description

This course explains advanced configuration and control of the Quantum HD Unity compressor controller used in industrial refrigeration systems.

It is intended for experienced refrigeration technicians, controls technicians, and engineers who are responsible for configuring compressors, optimizing system performance, or supporting commissioning and troubleshooting activities.

QTM 320 goes beyond operator interaction and focuses on how configuration settings, PI control loops, capacity control strategies, economizers, VSDs, condenser controls, and sequencing logic work together. Learners gain a clear understanding of how incorrect configuration values lead to instability, inefficiency, nuisance trips, or equipment damage.

The course also introduces advanced protection and monitoring features, including liquid injection cooling, separator condensing and dewpoint safeguards, and PhD Plus vibration monitoring as part of mechanical integrity and predictive maintenance programs.

QTM 320 fits as the advanced Quantum controls course, bridging controller configuration with real‑world system performance and reliability.

Sections include:

• Package and Compressor Configuration
• Capacity Control and PI Logic
• Economizer and VSD Integration
• Oil System and Drive Configuration
• Advanced Safeties and Protection
• Condenser Control Strategies
• Compressor Sequencing
• Advanced Monitoring (PhD Plus)
