Glycol Heat Trace Module - Qnergy | Reliable Remote Power
The Glycol Heat Trace (GHT) feature allows for the waste heat from the Stirling engine and it's exhaust to be used by the customer. A plate heat exchanger is used to separate the engine coolant and the GHT media. The GHT media is circulated using a rotary vane pump on a variable speed motor. The PowerGen monitors the supply and return temperatures of the GHT media and adjusts the units operation to match the heat load and meet the return temperature set point. The GHT feature can be disabled with the use of the winter/summer toggle switch. Glycol Heat Trace Module Benefits Over 50,000 BTU/HR of heat available No external power supply required User selectable return temperature Ultra-reliable rotary-vane circulating pump Independent glycol reservoir Full monitoring and control Ideally suited for remote locations www.qnergy.com Heat Glycol Heat Trace Capture Your Full Power Potential GHT Module Specifications Minimum Return Setpoint Temperature 77 F Maximum Return Setpoint Temperature 131 F Maximum 1/2" tube length 1500 ft.

How It Works
Qnergy’s Free-Piston Stirling Engine (FPSE) generator can transform virtually any heat source into electricity. Once heat is applied to the FPSE the heat exchangers maintain a temperature differential across the engine causing the piston to shuttle back-and-forth. The oscillating helium drives the linear reciprocating motion of the piston, which by means of an integral linear alternator, directly converts the mechanical motion of the piston into electrical power.
The Qnergy engine has fewer moving parts than traditional kinematic Stirling engines, and no direct-contact points that cause wear and require lubrication. The Qnergy engine is truly a maintenance-free technology and offers long-life performance, two key features that make it an ideal power source.
Qnergy (q-ner-gy) is a company focused on providing ultra-reliable power solutions. Our technology is rugged, cost-effective, and efficient. With more than 40 years of expertise and proven reliability, Qnergy brings proprietary, high-performance Free-Piston Stirling Engine technology to the marketplace to integrate within commercial and industrial applications.
