High-quality materials
At Van Dijk heating, we make all our products in-house. Besides expert craftsmanship and direct involvement in the manufacturing process, we safeguard the quality of our extensive product range for the greenhouse horticulture industry by working exclusively with high quality materials. To aid this process, we recently installed a completely new ERP system. It goes without saying that our entire product range complies fully with all the relevant inspection requirements in the Netherlands and abroad. Van Dijk heating is ISO 9001 certified and has attained the HortiQ BRL 8001 quality system certificate for ‘Companies in the greenhouse construction sector’, the Dutch quality system for suppliers to the greenhouse horticulture industry. And as you will have come to expect from us, all of our equipment carries the CE quality mark, which means that it complies with all relevant European directives. We have also attained GOST-R certification, allowing us to import our products into Russia.

P.M. van Dijk, the founder of the company and the person who gave it his name, started to manufacture retarders in horticultural premises in Nootdorp. These eddy-current strips increase the turbulence of flue gases in boiler flame tubes, resulting in improved heat transfer. Saving energy and improving yields have been a constant priority throughout the company’s history.

The turbulent 1970s: Following the oil crisis in 1973, the price of gas increased significantly and growers started to become more interested in saving energy. It soon became clear that the installation of retarders in boiler flame tubes yielded savings of 2-3%. Mr van Dijk recognised this fact and it was this that gave rise to Van Dijk heating in 1975. Today we are still producing large numbers of retarders, primarily for boiler manufacturers in Europe, at our current premises in Bunnik.

Further growth 
At the end of the 1970s, the development of a flue gas condenser kick-started the next phase of our growth. This equipment also enables growers to save a lot of energy. During and after the oil crisis in the 1970s, this flue gas condenser helped us gain a significant market share, thus strengthening the foundations of the company.

At the beginning of the 1980s, the horticulture industry made a cautious start with dosing CO2 from boiler flue gases. By supplying guaranteed high-quality products and by advising on and producing calculations of systems tailored precisely to customers’ needs, we were able to secure our position as market leader in CO2 dosing systems in the greenhouse horticulture industry.

New introductions
In about 1990, a demand for disinfection systems for excess drainwater arose as a result of the increasing pressure from environmental requirements and the introduction of substrate (hydroponic) cultivation. In response to this situation, we developed the ECOSTER series of drainwater disinfectors. Our heat-based drainwater disinfection system is a simple one and the only system to guarantee 99.9% disinfection.

Conditioned cultivation facilitates energy savings, improves the greenhouse climate and delivers better crop results. One of the aspects in Next Generation Growing is dehumidification of greenhouse air with relatively dry outdoor air. In response to this, in 2008 we developed the Active Ventilation System (AVS). This system makes an active contribution to an improved greenhouse climate, resulting in energy savings and greater efficiency. In 2012, this product group was extended to include the AVS WTW, the AVS-C and our very own climate greenhouse.

Since the foundation of Van Dijk heating in 1975, we have successfully developed and marketed a wide range of innovative products for the greenhouse horticulture industry. These early products are still being produced in-house to this very day. They form the basis of our organisation, which always looks towards the future armed with the knowledge and experience we have gained over the course of our history.

Our core values have remained unchanged over the years: constantly innovating is our motto and quality and service are a given in all our dealings with customers. Our relationships with our customers, many of whom are long-standing, are characterised by open and direct communication, for which flexibility and highly experienced specialist staff are essential.

Our vision:
To create an energy-efficient climate for greenhouse horticulture.

Our mission:
We aim to make life easier for installers and end users by developing and manufacturing innovative standard products that will save energy, optimise the greenhouse climate and promote plant growth.
