Descripción del producto

Since 1953 Van der Hoeven has been designing and realizing horticultural projects worldwide. Always offering complete, tailor made solutions for growers, defined to provide them with maximum returns on their investment. With the new ModulAIR concept, Van der Hoeven takes another step forward by introducing a flexible, modular and controlled greenhouse system for all sorts of climate conditions. The ModulAIR system has been designed to accommodate a variety of technical available solutions. Being modular also means these components can be easily adjusted to the growers needs. This allows for ideal integration of necessary components, dependant on greenhouses specific requirements.

The ModulAIR air treatment is built as a small corridor, the ModulAIR corridor, located on the outer
gable end walls of the greenhouse. The system works by using outside air for cooling and dehumidification and inside air for re-use and recovery of valuable CO2. This ModulAIR corridor is used as a mixing chamber for different sources of air before distributing it back into the greenhouse.

Sustainable stainless steel insect netting in front of the outside air inlet and integrated high quality nylon harmonica insect netting in the ModulAIR roof windows ensure that insects are kept outside of the greenhouse. This has proven to reduce pesticide reliance and the spread of disease within the crop.

Under each crop gutter, high quality PE air ducts are installed. This air duct is distributing the conditioned air from the ModulAIR corridor throughout the greenhouse which helps to create and control a homogenous climate, critical for even cropping, heat, and CO2 regulation. This conditioned air is transported by an EC fan in front of the air duct. The fans are individually speed controlled.
With these fans, the capacity of the ModulAIR system can be controlled and adjusted instantly.

The main heating consists of a pipe rail system and often a grow pipe system. In colder climates the ModulAIR chamber will be provided with heating modules which is an optional addition for extra heating. The heating modules have their own fans attached which will run when the heating modules are active.

The ModulAIR greenhouse can also be equipped with a pad cooling system for temperature and humidity control. This is the most efficient and effective method of cooling greenhouses while also giving a method to add humidity. When the outside air temperature becomes too high,
the pad can be activated to cool down the outside air and increase the cooling capacity. The pad uses
water and evaporation techniques to cool incoming air.

As the ModulAIR is designed to the growers needs, a detailed location analysis is used and the optimal components are selected in the correct dimensions. For example, in extreme climates with excessive heat and high humidity, it’s also possible to add an optional mechanical cooling system.

In essence the ModulAIR greenhouse brings:
• a better controlled greenhouse climate
• optimized use of energy and CO2
• minimum use of pesticides
• better quality of crops
• sustainable production
which combined result in better returns on investment.

By adjusting ModulAIR step by step to adapt to the requirements of the crop, the local climate and
availability/costs of energy, the client can choose the best customized solution. In some areas dehumidification could be enough to have great results, in other cases the cooling is essential. The first commercial successes have already been achieved, as expected with different options for each project. With this new development in the field of technology and climate, Van der Hoeven proves itself again to be a firm player in international and professional horticultural projects, in which economic feasibility and sustainability fit together.

Descripción del expositor

Over the past decades, Van der Hoeven Horticultural Projects B.V. has increasingly evolved from a company specialising in greenhouse construction to a provider of turn-key projects. The greenhouses, including all the crucial installations, we design and manufacture ourselves. This in-house development enables us to meet customer-specific requirements in a most flexible way. Based in the very heart of the major Dutch horticultural production region, we have gained a huge amount of first-hand practical experience over the years. We approach each project separately to find the best way of meeting our customers’ wishes and their specific cultivation requirements. Also if those wishes and requirements should call for innovative solutions.

Van der Hoeven is a professionally run organisation that still shows the characteristics of the family company from which it originated. You may expect a high level of commitment from our employees. You will find yourself dealing with enthusiastic specialists in all fields and at all levels - specialists who enjoy searching for the right solutions and who are not afraid of embarking on a new course to find them.

The world around us is changing at an incredibly fast pace. The future shortage of fossil fuels forces us to search for alternative energy sources. Water will become scarcer, so cultivation methods will have to allow for water recycling. Today’s consumers want to know the origins of horticultural produce and demand better guaranteed food safety. All over the world growers are expected to meet more stringent environmental standards. The number of consumers capable of purchasing fresh vegetables and ornamental products is growing in emerging industrial countries. For consumers, sound cultivation methods are moreover increasingly becoming a decisive criterion in the selection of vegetables and ornamental products. Sustainability is their key concern. And production that is now restricted to a few centres in the world will become more global. It’s now up to the greenhouse horticulture sector to find ways of meeting those challenges. The sector already has the necessary knowhow. And it’s more than willing and ready to take up the challenges. Over the years, our sector has time and again proven that it is capable of pushing back frontiers. Frontiers in the fields of efficiency, technology and food safety. We shouldn’t underestimate the challenges currently facing our sector. But effective use of our various specialisations and the efficient cooperation that characterises our sector will enable us to increase our outputs while using fewer resources. And to make our production methods and produce safer, healthier and more environmentally friendly. There are already numerous companies that are setting the right example. Van der Hoeven is one of those companies. Since 1953 we have been making continuous efforts to find ways of raising greenhouse horticulture to a higher level. We are ready to shape the future.

We establish projects all over the world, from Europe to Australia, from Asia to North/South America. Van der Hoeven has long-term partnerships with countless satisfied customers. We will gladly enter into a similar partnership with you too. If our approach appeals to you, please don’t hesitate to contact us to find out more about what we do or check our website!
