Optifuse IR

Optifuse IR is a diffusion coating for greenhouses that combines a very high diffusion rate with the reflection of infrared radiation. It was developed for hot areas and sensitive crops, on glass and plastic roofs alike. The grower adjusts the dilution and the application method, then cleans the coating off with Topclear Fuse whenever needed.

Diffused light reaches every leaf of the plant, high and low, while part of the infrared radiation is sent back. Studies have shown that diffuse light combined with a drop in temperature has a beneficial effect on production, quality and crop growth.

With 17 buckets per hectare, Optifuse IR reaches 85% diffusion, 89% PAR light transmission and 17% NIR reflection. With 22 buckets, diffusion rises to 90% and NIR reflection to 22%, for a PAR transmission of 86%.

Optifuse IR goes onto the outside of any greenhouse type, on glass and plastic roofs alike. It is meant for hot areas, while Optifuse is designed for regions with a moderate temperature.

Application is done by machine, by hand, by drone or by helicopter, on a clean and dry roof. The machine is preferred, as it gives a more even spread and limits product loss.

Optifuse IR is cleaned off with Topclear Fuse, at the moment the grower chooses. Cleaning calls for at least 240 L of Topclear Fuse per hectare, diluted in 1,260 to 1,760 L of water, depending on the application method. Topclear Fuse is applied when substantial rain is forecast within the week, on a dry roof.
