Diffuse irradiance measurements: Diffuse Horizontal Irradiance measurements are performed with a thermopile sensor called Pyranometer mounted on a Sun tracker or shading ring. When the pyranometer is installed on an automatic sun tracker, the diffuse radiation can be measured in two different ways. Measuring Diffuse irradiance requires an accurate pyranometer with low offset properties. Duirng clear sky conditions the DHI irradiance (W/m2) is less than 20% of the total irradiance. Zero offsets lead to...

The largest threat to wetlands is the risk of being flooded with sediment as a result of a poorly managed construction site. Most construction projects require erosion control to prevent damage to the wetlands.

Evaporative water loss is a growing environmental problem throughout the world. IEC covers provide an effective solution to mitigate this problem by shielding the water surface from wind and sunlight. Unlike floating ball and hexagon shaped covers, IEC covers do not have hundreds or thousands of seams or interstitial spaces that rotate and move. Our floating cover products shade and insulate 100% of the water column from the sun, further lowering the temperature and susceptibility to evaporation. IEC covers...

Keeping your offshore helideck free of bird guano, 24 hours a day, 7 days a week. The helidecks of offshore installations are an ideal habitat for birds to breed and forage. Helidecks are among the few resting places in the area and are often without human presence, making them an optimal place for birds to perch.
The presence of birds and bird guano at platforms is a globally recognized problem that can seriously jeopardize safety for the helicopter movements and working...
