What Questor Technology does

Questor Technology Inc. is a Calgary-based clean combustion technology company that designs, manufactures, and services enclosed thermal oxidizers (the Q-Series) for oil and gas operators, rail terminals, landfill and biogas facilities, and industrial sites. Its core Q-Series hardware uses a patented natural-draw combustion architecture with no fans, blowers, or moving parts, achieving third-party ISO 14034-verified destruction efficiency above 99.99% for methane, VOCs, H2S, BTEX, and hazardous air pollutants with zero visible emissions.

The company's integrated product portfolio consists of three components. Q-Series is the core capital equipment (seven models from Q50 to Q5000, 5-5000 MCFD capacity) sold via direct enterprise field sales with quote-based pricing and multi-year contracts, and offered as portable rental units for short- and long-term deployment. Q-Insights, launched in 2019, is a cloud-based SaaS monitoring and automated regulatory reporting platform sold as an annual subscription. Q-Power, introduced in 2022 and now being commercialized with the support of a C$1.9M NRC IRAP grant, is an Organic Rankine Cycle waste-heat-to-power module that converts Q-Series exhaust heat into grid-ready electricity, providing an energy monetization layer on top of emissions compliance.

Questor operates a direct sales-led go-to-market targeting enterprise operators and mid-market industrial customers across 27 countries, with 1,000+ units deployed globally since founding in 1994. Named enterprise references include Whiting Petroleum (Bakken Shale flaring elimination), Nexen (urban Calgary well workovers), Edmonton Crude Oil Rail Terminal, and Indonesia's Jambi Merang Development. The company listed on the TSX Venture Exchange in 2001 under ticker QST and, as of April 2026, had a market capitalization of approximately C$8.26M at C$0.30 per share, with a consensus analyst price target of C$0.50.

Revenue model

1. Q-Series Hardware Sales: Sale of enclosed combustion units (Q50 through Q5000 models) to oil & gas operators, industrial facilities, and other customers. Units range from 5-5000 MCFD capacity. Custom configurations available based on application requirements.
2. Rental Units: Portable rental units deployed on long-term contracts across customer sites. Q5000 portable units available for short and long-term rental. Low utilization of rental units noted as a factor in Q1 2026 revenue decline.
3. Q-Insights SaaS Subscription: Cloud-based monitoring and emissions reporting platform sold as subscription. Real-time data, automated compliance reports, and predictive analytics delivered via secure web portal and API. Encrypted cellular or satellite uplink.
4. Q-Power Waste Heat Recovery Systems: ORC-based waste-heat-to-power systems that generate electricity from combustion exhaust. Revenue generated from system sales and potentially ongoing energy generation. Grid-connected power can be sold or self-consumed.
5. Professional Services: Engineering consultation, site assessments, custom configuration design, and technical support services. Company offers free assessments for solution fitting.

Core offering

Questor Technology designs, manufactures, and sells enclosed combustion equipment (Q-Series thermal oxidizers) that destroy methane, VOCs, H2S, BTEX, and other hazardous air pollutants from industrial waste gas streams at >99.99% efficiency. The company complements this hardware with a cloud-based emissions monitoring SaaS (Q-Insights) and an Organic Rankine Cycle waste-heat-to-power module (Q-Power), sold primarily to oil & gas operators, rail terminals, landfill/biogas facilities, and industrial sites in 27 countries.

Product overview

Questor Technology offers a three-product integrated portfolio for emissions reduction and energy recovery: Q-Series serves as the core enclosed combustion platform with natural-draw thermal oxidizers delivering >99.99% verified combustion efficiency; Q-Insights is a cloud monitoring add-on that provides real-time telemetry, automated regulatory reporting, and predictive analytics; Q-Power is an ORC-based waste-heat-to-power module that captures exhaust heat from Q-Series units and converts it into electricity. The products are designed to work together as a complete emissions management system, from combustion to monitoring to energy monetization.
