Inductive-Thermal Dynamic Stripping Process (IT-DSP™)
Engineered Heat for Difficult Contaminants
IT-DSP™ is VIYA’s proprietary induction heating technology. It delivers energy directly into the heater casing and surrounding soil, reaching temperatures up to 1292°F at more than triple the output of conventional electric heating, enabling reliable treatment of hard, low-permeability zones and high-boiling-point contaminants such as PFAS and 1,4-Dioxane.

Where IT-DSP™ Excels
Built for High-Temperature Remediation
IT-DSP™ is a high-output induction heating technology for in situ and ex situ applications, well suited to dry soils, low-permeability formations, bedrock, and contaminants requiring elevated treatment temperatures.
Complex Contaminants
- PFAS, including PFOA, PFOS, PFHxS, and PFNA
- High-boiling and thermally resistant contaminants, including PCBs, PAHs, and 1,4-dioxane
- Chlorinated and other volatile organic compounds, including TCE, PCE, DCE, VC, and BTEX
- Mercury
- Petroleum hydrocarbons, including TPH LNAPL and DNAPL source zones
Challenging Site Conditions
- Bedrock and other low-permeability formations
- Heterogeneous or dry formations where sustained high-power input is required
- Applications requiring high power density or elevated treatment temperatures
- Sites with buried infrastructure or utilities requiring adaptable well layouts
Constrained Environments
- Active facilities where operations must continue during treatment
- Space-constrained sites requiring flexible equipment and wellfield layouts
- Source zones where previous remedies have left residual contaminant mass or failed to reach deeper impacts
How It Works
Direct-Contact Induction for Sustainable Heating
IT-DSP™ uses direct-contact induction to deliver energy into the steel heater casing and surrounding soil, providing efficient and controlled heating across a wide range of subsurface conditions. Each inverter supplies up to 50 kilowatts of power, with output exceeding 1,000 watts per foot, helping support predictable treatment in dense soils, low-permeability zones, and bedrock.
VIYA manufactures, owns, and operates its own IT-DSP™ equipment, with safety engineered into every system through UL 508A-listed assemblies, certified components, interlocks, redundant emergency shutdowns, and site-specific electrical protection.
Remote Distribution Panel (RDP)
Receives site power and distributes three-phase power to groups of Induction Control Inverters (ICIs). The RDP provides the transformer, switching, and power distribution functions required to supply and control the IT-DSP™ heating system.
Induction Coil Inverter (ICI)
Converts incoming AC power into controlled, high-frequency AC for the IT-DSP™ heaters. Each ICI is rated at up to 50 kW and can supply multiple heaters, allowing power input to be adjusted based on site conditions and thermal performance. CSA/UL listed (UL508A standard) in North America
Treatment system
Extracted vapors and liquids are conveyed to an aboveground treatment system engineered for the contaminants and operating conditions at each site. Treatment may include cooling and condensation, phase separation, filtration, air stripping, activated carbon, chemical conditioning, or other processes required to meet project-specific discharge criteria.
IT-DSP™ Heater
Installed inside a steel heater casing within the treatment zone. High-frequency current through the heater generates an alternating magnetic field that induces electrical currents directly within the steel casing, causing the casing itself to heat. Thermal energy is then transferred directly into the surrounding formation by conduction.
Soil Vapor and Multiphase Extraction
Extraction wells maintain pneumatic and, where required, hydraulic control while recovering volatilized contaminants, steam, groundwater, and mobilized NAPL from the treatment zone.
Temperature Sensors
Subsurface temperatures are monitored continuously throughout thermal operations using distributed temperature sensor wells. High-temperature IT-DSP™ applications use digiTC™ thermocouple arrays capable of monitoring the elevated temperatures associated with high-temperature treatment. digiTAM™ temperature monitoring may also be used for lower-temperature applications

Choosing the Right Path
The Right Technology Starts With the Right Assessment
No two contaminated sites are alike. While IT-DSP™ is highly adaptable across a wide range of contaminants and site conditions, the right remediation approach depends on the specific challenges and objectives of each site. We work with our clients to identify and execute the solution that provides the best balance of treatment performance, schedule, cost, and site-specific feasibility.
Explore other remediation approaches based on your site's conditions.
Heterogeneous Subsurface
For VOCs, SVOCs, NAPLs, and mixed-contaminant source zones where high-temperature conductive heating is not required, VIYA’s ET-DSP™ technology provides rapid, uniform heating across heterogeneous and variable-resistivity formations with high energy efficiency.
Permeable Source Zone
Where subsurface permeability allows steam to move effectively through the treatment zone, Steam Enhanced Extraction (SEE) can rapidly deliver heat, volatilize contaminants, and mobilize NAPL for recovery. In suitable formations, SEE can provide an efficient alternative to electrically driven thermal treatment.
Metals & Inorganic Contaminants
When heavy metals are present, the recovery and treat mechanism will not fully remove or degrade them. Chemical and biological treatment makes metals easier to contain or remove by changing how they behave, rather than destroying them.
