Bosman Van Zaal has introduced the OptiDry series of dehumidifiers, utilizing R290 (propane) as a natural refrigerant to provide a sustainable, energy-efficient solution for horticulture. These dehumidifiers are designed to meet growing demands for energy savings, disease prevention, and future-proof compliance with environmental regulations.
Since 2015, Bosman Van Zaal has been offering customized dehumidification systems for clients like WUR Wageningen, Bayer Crop Science, and B-Four Agro. Their R&D department has now developed plug-and-play OptiDry models that are compatible with various crops and growing systems, from high-tech climate chambers to fruiting vegetable crops.
Tackling F-Gas Regulations in Horticulture
Traditional dehumidifiers rely on synthetic refrigerants with high Global Warming Potential (GWP), contributing to greenhouse gas emissions. With the EU’s F-gases regulation (EU 2024/573) set to phase out these refrigerants between 2025 and 2030, maintaining such systems will become increasingly challenging.
Low-GWP refrigerants like PFAS also face environmental scrutiny, leaving natural refrigerants like CO2, ammonia, and propane as the future-proof options. To address this, Bosman Van Zaal developed the OptiDry series, using R290 (propane), which has a GWP of just 3, making it an eco-friendly solution.
The OptiDry Range: Future-Proof and Efficient
The OptiDry dehumidifiers offer an efficient, sustainable solution for horticulture. The use of R290 ensures compliance with both current and future regulations while improving energy efficiency and reducing operating costs.
The OptiDry Compact X is designed for highly efficient air drying, easily connecting to chilled water or free cooling circuits. Its integrated cross-flow heat exchanger saves 30-50% on cooling capacity, making it an ideal choice for a variety of growing environments.
The OptiDry Advanced DX is a versatile unit for drying, cooling, and heating air, perfect for greenhouses and plant growth chambers. Weighing just 105 kg, it delivers high-efficiency dehumidification of up to 4 l/h*KWh. With R290, it outperforms models using synthetic refrigerants in both energy efficiency and environmental impact. The hydroloop version offers additional flexibility for active climate control through a water circuit.
Conclusion
The OptiDry series presents a future-proof, energy-efficient solution for the horticulture sector. By adopting natural refrigerant propane, these dehumidifiers not only comply with evolving regulations but also offer growers a sustainable, cost-effective way to manage air quality and climate control. Bosman Van Zaal’s commitment to innovation ensures that the OptiDry range will remain at the forefront of environmentally responsible dehumidification for years to come.
