About us

IEG established itself as a pioneer in the field by developing revolutionary in-situ groundwater circulation technologies. Since 1990, IEG systems and technology have been used to successfully remediate hundreds of sites across the world via application of Groundwater Circulation Well (IEG-GCW®) technology.

IEG’s services includes design, manufacturing, assembly and start-up of our products. Maintenance, service, and operation has been done always with local distributors or environmental professionals, which are educated and trained during process installation. IEG technologies are commonly used to remediate soil and groundwater that has been contaminated with petroleum and chlorinated hydrocarbons, heavy metals, pesticides, etc.

Through IEG’s cooperation with research institutes and innovative companies in the area of water and groundwater treatment, energy storage, we can integrate new processes in our systems and expand our portfolio to solve environmental problems.

Groundwater Circulation Well (IEG-GCW®)

Groundwater Circulation Well (IEG-GCW®)

The Groundwater Circulation Well (IEG-GCW®) is an in-situ system for the remediation of contaminated aquifers.

Compact Stripper (IEG-CVS)

Compact Stripper (IEG-CVS)

IEG's Compact Vacuum Stripper (CVS 1000) is an innovative system for the removal of volatile organic compounds (VOCs) from contaminated groundwater. Highly efficient in its design and effective in operation, the system is capable of receiving and treating up to a maximum of 12 m²/h of highly contaminated water, with a VOC removal efficiency of up to 99.5%.

Ground Heat Exchangers

Ground Heat Exchangers

Ground Heat Exchangers / cooling system:
Air is moved through an undergound array of heat exachanger tubes that will cool the air. During summer season the system can be used to cool and during the winter season heat can be extracted from the underground.
