Adiabatic cooling is based on the thermodynamic principle that evaporating water draws heat from its environment resulting in a lower ambient temperature. As a consequence, adiabatic cooling only works in areas with relatively low humidity. Adiabatic cooling can be used to control the temperature and humidity (dehumidifying) in the greenhouse.
Adiabatic cooling can be achieved by traditional pad and fan cooling, pad and fan cooling in a semi-closed greenhouse, or high pressure fog.
Mechanical cooling is used in greenhouses in situations where the outside conditions (high humidity) do not permit the use of alternatives based on adiabatic cooling. Both CAPEX (investment) and OPEX (running costs) are higher than cooling based on adiabatic cooling. The cooled air is usually blown into the greenhouses through ducts. Mechanical cooling can be used to control the temperature and humidity (dehumidifying) in the greenhouse.
Mechanical cooling is done by electrical chillers, a heat pump or an absorption chiller.
With sustainable heating, we are making current businesses more durable and environmentally friendly. For sustainable heating, you can use a heat pump and electric boiler. Around the equator, we can install solar thermal energy generation.
Circulation fans offer a solution for every indoor climate challenge. Bosman Van Zaal offers fans that are specifically designed to evenly distribute air in an energy-efficient way. Vertical or horizontal airflows reduce temperature and humidity differences and create a uniform climate.
When using circulation fans, the reach of the airflow expelled by the fan in an infinite space without obstacles has to be calculated. This distance is also called the throw of a fan. To mix the air well, it is important that the fans are properly aligned so the air is blown from fan to fan.
Climate computers, sensors and software steer processes that create and control an ideal climate and measure the relevant parameters. There are many possibilities, from models with buttons controlling the ventilation to models with LCD screens controlling several complex installations and sections. We are the official supplier of various brands of climate computers, including Hoogendoorn, SERCOM and Ridder.
Making the operation of horticultural businesses child's play - that is what software should do. There are various software systems that collect, analyse, and predict. This gives growers effective insight at all times. With powerful computers and extensions, you have a complete, yet flexible and user-friendly system that keeps you in perfect control of your plant production.
From Vision to Solution
Based on intensive customer contact, we work on integrated solutions. Solutions that utilise labour, time, raw materials, and space as efficiently as possible. At Bosman Van Zaal, product development and realisation are performed in-house by our own multi-disciplinary teams. Our step-by-step approach starts with your vision and ends with our technical solution with lifelong service.
What are your wishes and challenges, and what do you define as optimal cultivation and maximum yields? Our multidisciplinary solution team starts by listening and will propose technical installations.
The final proposal is then translated into smart, inventive, and practical designs by our own team of engineers. We base this on our many years of experience and use the latest technology and insights.
The technical solutions are manufactured in our automated machine park by our qualified production team. We ship worldwide and work with our own staff or in collaboration with (local) partners.
After delivery, we stay in contact with your company. We provide employee training, and we offer 24/7 service online and on location, guaranteeing a long and efficient service life of the technical installations.
Our team consists of experienced engineers, technicians, and programmers in areas of expertise such as data, cultivation, vertical farming, and internal logistics. We design and manufacture everything in-house at our head office and modern factory.
This ensures a high level of flexibility and accessibility. Characteristics of which we are very proud!Read more
