950-GEO1 Geothermal Learning System
by Amatrol

Geothermal heat pump systems are one of the most efficient and fastest-growing segments of residential and commercial HVACR. By using the earth's stable underground temperature as a heat source and sink, geothermal systems deliver heating, cooling, and hot water at efficiencies that conventional HVAC systems cannot match, and they do so with no combustion, minimal maintenance, and long operational lifespans. As more homeowners, commercial building owners, and institutions turn to geothermal technology, the demand for qualified geothermal technicians is growing steadily, and the technical depth required to install, service, and troubleshoot these systems is significant.

The Amatrol 950-GEO1 Geothermal Learning System with Desuperheater gives learners the foundational knowledge and hands-on skills they need to work confidently with geothermal heat pump systems in residential and commercial applications. It packs a residential-sized geothermal system into a compact, mobile vertical trainer that fits through a standard door, exposing components that are hidden in actual installations so that learners can observe, monitor, and test each element of the system as it operates. The system puts learners on a solid path toward IGSHPA certification, the industry-recognized credential for geothermal technicians.

Klein Educational supplies Amatrol HVACR and alternative energy training systems to CTE programs, community colleges, and technical training centers across California, Oregon, Washington, Arizona, Nevada, Hawaii, and Alaska. As the only authorized Amatrol distributor in these seven states, we help programs get the right system configured and running.

What is the Amatrol 950-GEO1?

The Amatrol 950-GEO1 Geothermal Learning System is a compact, 6-foot mobile training system that packs a complete residential-sized geothermal heat pump system into a vertical trainer that fits through a standard doorway. Major components include a 2-stage compressor with a 2-ton heat pump, a ground simulator, an air duct with an ECM blower, a ground-source loop with flow center and header loop, and an industrial-grade geothermal controller, along with a water-coil heat exchanger, sight glasses at multiple points in the system, ample temperature and pressure monitoring, and electrical test points throughout.

The exposed component layout is one of the 950-GEO1's most important design features. In actual geothermal installations, most system components are hidden within the building, in mechanical rooms, or buried underground, making hands-on access for training purposes essentially impossible. The 950-GEO1 mounts all components visibly on the vertical panel, labeled for identification, with full access for observation, measurement, and hands-on skills practice that reflects what technicians actually do when servicing a geothermal system.

The ground simulator is a temperature-controlled system that creates a constant temperature to act as a realistic heat source and sink, enabling the system to run continuously as it would in an actual installed geothermal application. This continuous operation capability is essential for teaching realistic system performance analysis and operating procedure skills.

The desuperheater

One of the most valuable features of the 950-GEO1 is the inclusion of a desuperheater. A desuperheater is a heat exchanger that uses the excess energy from the geothermal system's refrigeration cycle, specifically the superheat in the hot refrigerant gas leaving the compressor, to heat domestic water at little or no additional energy cost. Desuperheaters are a standard feature of modern geothermal installations and represent a significant component of the efficiency advantage that geothermal systems offer over conventional HVAC.

Students learn the operation, startup, shutdown, and maintenance of the desuperheater as an integrated part of their geothermal training, developing the specific competency with this feature that technicians need to properly commission, adjust, and service it in real installations. The desuperheater is often the component that homeowners and building owners are most interested in maximizing, making technician knowledge of its operation directly relevant to customer service quality.

What students and trainees learn

The 950-GEO1 curriculum begins with an introduction to geothermal heat pump systems and moves progressively through the concepts, components, and skills that make a geothermal system operate. Amatrol's curriculum builds from the basics steadily toward more complex system operation and maintenance topics, with each theoretical concept paired directly with a hands-on skills activity on the trainer.

Geothermal system fundamentals cover geothermal heat pump system principles and advantages, ground source energy concepts, coefficient of performance calculation and interpretation, heat duty calculation, and energy units of measure specific to geothermal system analysis.

System component topics cover closed-loop source circuit operation and components, high-density polyethylene pipe specifications for geothermal applications, flow center and header loop operation, 2-stage compressor operation and characteristics, condenser and evaporator operation in the geothermal context, metering device types and operation, refrigerant properties and handling in geothermal systems, suction line accumulators and receivers, dryers and moisture indicators, and water-coil heat exchanger operation.

Control and operation topics cover geothermal controller operation and programming, thermostat operation and integration with the geothermal system, ECM variable-speed blower operation and adjustment, heat pump system startup procedures, normal system operation monitoring, and shutdown procedures.

Performance analysis topics cover interpreting pressure and temperature gauge readings at key system points, using sight glasses to observe refrigerant state changes throughout the cycle, system performance measurement and coefficient of performance verification, and identifying degraded performance before component failure occurs.

Desuperheater topics cover desuperheater operating principles and hot water generation, desuperheater integration with the geothermal refrigeration cycle, startup and shutdown of the desuperheater, and desuperheater system maintenance.

Maintenance topics cover startup and checkout procedures, flushing, purging, and charging the ground source loop, glycol/water solution management, and routine maintenance procedures for all major system components.

IGSHPA certification preparation

The 950-GEO1 puts learners on a solid path toward earning the International Ground Source Heat Pump Association (IGSHPA) certification, providing an excellent foundation in topics such as startup and checkout procedures, flushing, purging, and charging the system. IGSHPA certification is the primary industry-recognized credential for geothermal technicians and is increasingly specified by geothermal installation contractors and system manufacturers as a condition of employment or partnership.

The 950-GEO1 in the context of Amatrol's geothermal lineup

The 950-GEO1 is the foundational system in Amatrol's geothermal training lineup. Programs that want to extend training into advanced troubleshooting can add the 950-GEO2 Geothermal Troubleshooting Learning System or the 950-GEO2D Geothermal Troubleshooting Learning System with Desuperheater, both of which build on the 950-GEO1 foundation with the addition of FaultPro electronic fault insertion for electrical, mechanical, and fluid-based fault training. The 95-GEO3 Geothermal Flush Cart Learning System can be added to teach loop flushing, purging, and charging procedures as a dedicated hands-on skills module. These systems together build a complete geothermal technician training pathway from foundational knowledge through advanced troubleshooting.

Multimedia eLearning curriculum

The 950-GEO1 includes Amatrol's interactive multimedia eLearning curriculum covering geothermal system topics using text with voiceovers, video, 3D animations, pictures, interactive activities, quizzes, and self-reviews. The curriculum is designed to be used in traditional classroom settings or by learners working at their own pace, making it suitable for both instructor-led programs and self-directed training environments. Amatrol's web-based eLearning is accessible on any WebGL-compatible internet browser and includes a Learning Management System that allows instructors to track student progress and assessment results.
