Product Description

Gas Collection & Gas Storage Covers

IEC has created custom covers for gas-collection and storage to meet your exact specifications and to ensure project success.


Industrial Gas-Collection Covers

IEC’s Floating Gas-Collection Covers are specifically designed for each client. IEC’s experience in custom design and field fabrication ensures a successful project. Certified IEC technicians have installed more than 10 million square feet of covers in some of the harshest industrial and environmental site conditions.

The following advantages and options are available with IEC’s gas collection covers:

  • Installed with little interruption to operations
  • Installed on tanks, ponds and lagoons of all sizes and shapes
  • Eliminates rainwater ponding problems
  • Eliminates gas ballooning
  • Provides high buoyancy and rigidity
  • Hatches provide access to internal equipment
  • Pre-manufactured panels improve quality so less field welds are required


Agricultural Gas-Collection Covers

Each IEC biogas collection cover system is designed with a gas-tight perimeter, so gases are continuously captured and channeled to perimeter piping where it exits the basin to be flared or used as fuel.

IEC gas-collection covers are designed to minimize inflation (ballooning) of the geomembrane to reduce vibration and fatigue from wind, which can significantly reduce the life span of a cover. IEC’s floating gas-collection covers use lateral floats, which keeps the entire cover floating on the liquid’s surface, eliminating cover inflation and exposure to wind damage.

Rainwater trenches are also created by strategically placing ballast weight of pre-determined size and weight in a configuration that allows rainwater to migrate to a sump enclosure, where it is pumped off the cover or directed back into the basin.

IEC’s biogas collection cover designs are proven to be among the best in the industry, and they can be specifically tailored to the needs of each customer.

Agricultural-specific gas-collection covers:

  • Provide the owner with an effective and low maintenance solution to covering their manure basins
  • Effectively collect biogas for flaring or use (CHP, boiler, RNG)
  • Effective for low rate anaerobic digesters
  • Help produce fertilizer in a form that is readily assimilated by crops


Gas Storage Covers

IEC offers the right solution for any type of gas storage. The need for gas storage is project specific and depends upon production and availability of space. Our vessels can be free standing or installed on tanks, containers or buildings.

The following advantages and options are available with gas-storage covers:

  • Designed by engineers with more than 25 years of continuous cover design experience
  • Methane (CH4) cover
  • Renewable gas cover
  • Gas collection cover
  • Anaerobic Digester cover
  • Digester cover
  • Gas storage cover
  • Operating Pressure Designs 5 – 70 MB
  • Turn-key Installation for Blower, PRV’s and Sensors
  • Short Lead Times and Installation
  • Storage from 50 to 5000 cu. Meters
  • Ultrasonic Height Gauge
  • Gas Pressure Sensor
