Since 1990 Soil-Therm has been specializing in the manufacture of custom environmental and emissions control equipment for a wide range of applications. Recent advancements in Soil-Therm`s patented Jet-Therm technology include In-Situ Thermal Remediation (ISTR) heating systems for soil heating applications. Small 4` burners capable of heat output in excess of 300,000 btus/hr, 1800F , and pressures >15 psig have demonstrated faster and less expensive heating times for contaminated sites. Advanced emissions control systems feature Soil-Therm`s patented direct fire Jet-Therm aerospace combustion process, achieving extremely high destruction efficiencies, maximum run time, chlorinated and VOC destruction with minimal maintenance. Our innovative designs coupled with our patented combustion technology results in smaller equipment sizes that bring you the greatest results.

About Us

Since 1990, SOIL-THERM EQUIPMENT, INC has been the industry leader in developing cleaner technologies for environmental and site cleanup applications. Our latest technology uses our Jet-THERM combustion process for GAS-FIRED soil heating, demonstrating an impressive 70% heat energy to the soil, resulting in very low cleanup costs for In-Situ Thermal Remediation (ISTR) applications.  CVOC destruction has also been achieved.

SOIL-THERM also offers a complete line of industrial thermal oxidizers, storage tank degassing equipment, remediation equipment, emissions control, and custom equipment solutions for industry, refineries, and all types of environmental and site cleanups. Please contact us to learn more.



SOIL-THERM EQUIPMENT, INC. has been supplying the industry with the finest remediation equipment since 1990, but the roots go back much further.  Mark Sujata, Founder and President of SOIL-THERM EQUIPMENT, INC, has shaped the industry with his innovative, state of the art technologies for environmental applications. Soil-Therm Equipment has received numerous awards and earned numerous patents for their innovative burner designs developed over more than 20 years of combustion research.


Upon completion of degrees in Chemistry/Biology, and a Masters Degree in Environmental Sciences, Mark landed a job overseeing the Environmental Compliance Program for The Marquardt Company, an aerospace company that developed advanced space and defense-related ramjet engines. In that role, Mark gained a working knowledge of every aspect of environmental compliance from water discharge to air quality, and hazardous waste storage and disposal laws. Working closely with regulatory agencies on all waste minimization matters for the 55 acre facility, Mark achieved a 95% reduction in hazardous waste disposal costs within a 4 year period.

A transfer to the Aeropropulsion Group gave Mark the opportunity to work with world-renowned experts in high speed flight and advanced aerospace combustion. This group pioneered the aerospace industry with such Mach 4+ accomplishments as the design and development of ramjet engines for the SR-71 Blackbird engine, the Blackbird D-21 Drone, Advanced Strategic Air Launched Missile (ASALM) and a Mach 8+ scramjet engine for the National Aerospace Plane project.


SOIL-THERM continues to set new equipment standards for the remediation industry. We are proud of our small, powerful thermal systems and their origins. Our equipment has the cleanest emissions while providing the highest destruction efficiencies. Along with the finest burner technology in the industry, SOIL-THERM builds systems with high quality standards and the latest control technology. Touchscreens with first out indication, and screen pages with operations and maintenance information, safety, troubleshooting, remote monitoring and control, and data-logging offers our customers equipment that is both versatile and powerful, yet small enough to fit almost anywhere.


Soil-Therm - Model Micro-ELECTRIC - Electric Oxidizer Systems

The Micro-ELECTRIC is the most popular of our electric oxidizer systems. Mounted onto a very small 4 ft x 3.5 ft skid, the 24 kW electric heater and heat exchanger provides amazing performance and efficiency at flows from 20 to 300 cfm.

Soil-Therm - Model Compact-THERM - Gas-Fired Thermal Oxidizer Systems

This is the oxidizer that started the revolution in powerful performance in compact sizes. Only 6 ft by 6 ft, with capacities to 700 cfm, powerful SVE or DPE blowers available, and the latest technologies come together in this big little powerhouse. Standard features include heavy duty skid with lifting rings and forklift slots, Roots 59 blower with 15 or 20 hp motor enclosure for sound attenuation, Jet-THERM burner, ceramic lined 24' oxidizer shell, ...
