Dry+ Climate

Dry+ Climate

Green Simplicity, in collaboration with OC Agri and Wagenaar Refrigeration, has developed a suitable solution for regulating the climate in (greenhouse) horticulture and beyond. The Dry+ unit is an all-electric, plug-and-play solution for cooling and dehumidifying, heating the air in the cultivation area.

General

The Dry+ Climate consists out of a fully electric air handling unit with an integrated heat pump, heat recovery and outdoor condenser. The system is distinguished by a higher efficiency up to 50 percent, compared to existing dehumidification systems.

With these technical applications, the Dry+ unit is able to cool, dehumidify and heat which results in more flexibility and control over the entire cultivation process.

The Dry+ unit is available in three different variants, so that the dehumidification demand of every grower can be answered with a matching type of air handling unit.

max. dehumidification per unit (18⁰C/80%):
✔ Dry+ 50 Climate | 50 l/h
✔ Dry+ 75 Climate | 75 l/h
✔ Dry+ 100 Climate | 100 l/h

Technical operation | Dry+ 50 Climate

The DRY+ unit works according to the recirculation principle. The unit extracts moist air from the greenhouse and dehumidifies that air by using the cooling block. Thanks to the integrated technology, the DRY+ Climate can dehumidify 50.5 kg/h with a nominal energy of only 11.1 kW (18°C / 80%) with a consumption of 0.22 kWh/L.

With a compressor of only 9.0 kW, the DRY+ has a cooling capacity of 66 kW and a heating capacity of 75 kW. The DRY+ uses 100% of the heat released during dehumidification. You can therefore heat your greenhouse with a net heating capacity of 39 kW (18°C / 80%).

Tailored advice

In collaboration with Wagenaar Refrigeration, Green Simplicity has already more than 20 Dry+ units actively running at various growers and breeders.

Air distribution

A good climate starts with a uniform distribution of temperature and humidity throughout the entire cultivation area. It is important that moisture does not accumulate at plant level and that the plant is not unnecessarily stimulated to evaporate.

The air distribution is an important part for optimal and uniform dehumidification within the cultivation area. To achieve this result, Green Simplicity looks for the most efficient way of introducing and displacing the air at crop level in each situation. There are several options for uniform dehumidification:

Air distribution throughout air hoses on Crop level:

With an air duct, different air distribution hoses can be connected to the DRY+ Unit. Depending on the situation, the ideal height is determined and an optimal discharge pattern is calculated to create a homogeneous climate above and between the crop.

Air distribution throughout larger distribution hoses for even input in cultivation space:

In an existing greenhouse longer than 40 meters, where the air is uniformly distributed by, for example, the network of horizontal or vertical fans, it is possible to introduce air with a few larger distribution hoses.

In this case, the distribution hoses are only used for the uniform introduction of dry, warm or cold air over the length of the department.

Free discharge with support fans:

In existing greenhouses with limited lengths (below 40 metres), a network of horizontal and/or vertical fans is often present to move the air at crop level. In this situation, the DRY+ can blow out the air freely into the room and the treated air is distributed through the existing network.
