The world of refrigerants is changing fast, as pressure increases on products with a high GWP (Global Warming Potential), and according to Bimco Holland it is only a matter of time before these refrigerants are phased out completely. This is why the company is introducing its new dehumidification unit, the Bimco-4Eco, for which a patent has already been filed.
"It is a compact, easy-to-install unit, designed with upcoming regulations in mind," says sales manager Joost de Goeij. "With a GWP of just 4.5 and the natural refrigerant R290, the 4Eco is completely future proof." The 4Eco is the successor to the Bimco-4E, a line of dehumidifiers designed to help growers save energy and maintain stable relative humidity levels inside the greenhouse.

From Bimco-4E to Bimco-4Eco: future proof on R290
While the previous Bimco-4E operated on refrigerant R407C, the new Bimco-4Eco switches to R290, or propane. That change brings several major advantages, Joost explains. "With a GWP of only 4.5, the 4Eco has a much smaller environmental impact than traditional synthetic refrigerants."
Another important advantage is that the unit no longer requires an annual mandatory F-gas inspection. "Because we use R290 and only a small amount of refrigerant, the legally required yearly leakage check is no longer needed, which saves growers both money and administrative hassle."
Practical benefits in the greenhouse
The Bimco-4Eco was developed with daily greenhouse practice in mind, says the young company that focuses on sustainable technology for protected horticulture. For best performance, growers are advised to install several units per section to improve air distribution. "By placing multiple compact units rather than one large central machine, the greenhouse climate becomes far more uniform. This helps prevent wet corners and cold spots."
The unit operates at a low sound level of 63 dB and produces a gentler airflow, so it does not create overdried zones around the machine. "The airflow is designed for a soft, horizontal release, keeping the immediate area from drying out and maintaining a more even climate."
Weighing roughly 140 kilograms, the compact unit is relatively light and easy to position using standard greenhouse logistics. It can be neatly installed between gutters, walkways or above a technical room. "No cranes or major structural changes are needed for installation."

Climate control, energy saving, and improved crop performance
Like previous models, the Bimco-4Eco is designed to save energy by allowing growers to keep vents and screens closed for longer, manage condensation and high RH, limit the risk of fungal and bacterial diseases, and create a more homogeneous climate, which leads to more uniform crops and higher yields. "By treating moisture internally instead of relying on cold outside air, growers can save up to 50 percent energy compared to traditional heating and venting, especially when combined with good screen management," Joost says.
It's possible to apply for an EG subsidy on the unit.
