Energy
Generator sets for combined heat and power, associated gas, data centers, standby and mobile duty — plus inspected pre-owned equipment with photos and owner-reported condition.
QR machines
These are separate machines from different manufacturers. Qualirex supplies them from a 100 kW stationary package through the 35 MW class. Open a model for its ratings, or ask and we will send the full sheet with the quotation.
Lineup
Six gas turbine generator sets, from 100 kW to 34.5 MW. Each is built by its own manufacturer and supplied by Qualirex. Select a rating to open its datasheet.
Models
QR-GT1000 ratings beyond output and fuel are sent with the quotation. The other models are specified on their own pages.

Applications
The same machines, in continuous duty, standby, or on a truck. Heat recovery figures below are the ratings for the named model.
Electricity plus steam, hot water or absorption chilling from one gas turbine.
The turbine generates power and recovers exhaust heat as steam, hot water, or heat to drive an absorption chiller. A QR-GT1800 delivers 1,800 kW together with about 6 t/h of saturated steam at 180 °C, or the equivalent in hot water. The QR-GT100 recovers hot water at 60 °C and 228 L/min. Heat serves process loads in manufacturing, refining and chemical plants, and building heating or cooling.
Fire associated gas on the lease instead of moving a modest volume to a distant pipeline.
Where the gas volume is limited and a transmission pipeline is far away, gathering, storage and transport cost more than the gas is worth. A small industrial gas turbine burns that associated gas on site and supplies power to the production equipment.
Prime or standby power for sites that need stable output, including AI loads.
Remote and smaller data centers can run a QR turbine continuously, or keep it as standby that starts when needed. AI halls add large loads and a high bar for reliability. Gas-turbine output holds voltage and frequency, including against harmonic and non-linear loads, without requiring a large grid connection at the site.
Fixed or mobile backup for facilities that cannot go dark.
Standby sets cover government sites, hospitals, 4G and 5G base stations, television and radio broadcast, airports and EV charging — installed in place, or brought in as a mobile unit.
A truck-mounted generating set for events, disaster relief and emergency response.
The vehicle-mounted QR-GT1800 is a self-contained generating set, 12 × 2.55 × 3.9 m and at most 32 t. It covers temporary duty where a fixed installation is not available: events, disaster relief and emergency response.
Compressor-fed combustion keeps output stable in thin air.
At high elevation the air is thin. Naturally aspirated engines draw that air directly, so combustion is less stable and efficiency falls. A gas turbine feeds its combustor from a compressor, which offsets the low atmospheric pressure and holds output more steadily.
Batteries and flywheels cover the transient; the turbine carries the sustained load.
Batteries, supercapacitors and flywheels start quickly, then discharge just as quickly and cannot be refilled in a short window. Past a certain power rating their capital cost rises sharply. Paired with a gas turbine, that storage covers the fast transient while the turbine supplies sustained energy.
Why a turbine
How an industrial gas turbine compares with a reciprocating gas or diesel engine.
| Parameter | QR industrial gas turbine | Reciprocating gas/diesel engine |
|---|---|---|
| Start reliability | 99.96% | 95% |
| Power quality | Stable voltage and frequency; strong tolerance of harmonics and non-linear loads | Weaker voltage and frequency stability; weaker tolerance of harmonics and non-linear loads |
| No-load operation | Sustained no-load and low-load operation | Brief no-load operation only |
| Cold start | −40 °C to 40 °C without pre-heat | Pre-heat required below −10 °C |
| Cooling | Air-cooled; no water system | Water-cooled, with water treatment |
| Lube oil consumption | Negligible | Significant |
| NOx | ≤60 ppm (≤25 ppm on low-NOx models) | ≥300 ppm |
| Vibration | 10–15 µm | 50–60 µm |
| Routine maintenance | Quarterly 15-minute run; oil test every 8,000 h; oil change every 16,000 h | Oil change every 1,000 h; filters, spark plugs and liners |

Support
With the turbine we can supply the parts and the control system, train operators, and stay on after commissioning.
Spare parts for the QR machines we supply, including control-system hardware.
Training for the crews who start, load and shut down the set.
Support after handover from the team that quotes the equipment.
On request, packages can ship in your branding, with your logo.
Share the duty — prime, standby, heat recovery or mobile — and we reply with a configuration and a quotation.
