01 — The technology
Heat the matrix.
Remove the source.
Electrical Resistance Heating turns the subsurface itself into the heating element. Alternating current moves between electrodes, generating controlled, uniform heat throughout the target treatment zone.
Contaminants are mobilized from soil and groundwater, captured through an integrated vapor extraction network, and treated above ground—without relying on excavation to reach the source.
Heat
The soil matrix acts as resistance, heating saturated and unsaturated zones.
Mobilize
Heat increases volatility and accelerates recovery from low-permeability soils.
Capture
Vapors and liquids are extracted, conveyed, and treated in a closed system.
Designed around your source zone
One platform.
Complex conditions.
ERH is engineered for the contaminant, treatment depth, target temperature, and operating environment—not a generic soil type.
- ✓Chlorinated VOCs
- ✓Petroleum hydrocarbons
- ✓LNAPL & DNAPL source zones
- ✓SVOCs and complex organic mixtures
FIELD SYSTEM
Integrated vapor capture and surface treatment
02 — Experience under pressure
Proven where
conditions are hardest.
Our work has moved ERH beyond open, uncomplicated sites. DOXOR teams have designed around people, structures, live operations, variable geology, and demanding cleanup objectives.
ACTIVE INDUSTRIAL SITES
Remediation without surrendering the facility.
Phased installation, controlled access, and engineered safeguards support treatment in highly occupied and operational environments.
Thermal treatment at a municipal school site.
Field experience treating benzene and TPH where safety, communication, and footprint control are critical.
01
From bench-scale evaluation to full-field ERH.
Research and field programs evaluate electrode geometry, energy delivery, subsidence, and heat-enhanced bioremediation.

03 — One accountable team
From first model
to final sample.
Thermal performance depends on the whole system. DOXOR keeps engineering, equipment, field execution, controls, and operational data connected from feasibility through closeout.
Feasibility & bench testing
We translate contaminant, geology, depth, and site constraints into a defensible thermal strategy before field mobilization.
Integrated engineering
Electrical delivery, electrodes, vapor extraction, surface treatment, and safeguards are designed as one coordinated system.
Field implementation
Our team installs, commissions, and operates the treatment system with live performance tracking and disciplined controls.
Performance verification
Temperature, energy, vapor, and contaminant data guide every operating decision through project closeout.
Data-informed execution
See the heat.
Manage the risk.
Digital twins, 3D site models, georeferenced thermal imagery, live operating data, and structured reporting turn field complexity into decisions your team can see and defend.
04 — DOXOR Thermal USA
Experience traveled.
Expertise arrived.
After more than two decades solving remediation challenges and 15 years advancing ERH in the field, DOXOR is bringing that accumulated expertise to U.S. projects.
You get a technically direct, senior-led team shaped by real sites—not theory alone.
