Van Dijk heating specialises in the development, production and supply of high-quality equipment that increases energy efficiency. The low maintenance products that the company supplies to the greenhouse horticulture industry in particular and industry in general have a long working life and a high level of reliability.

Over the last 35 years, the organisation has gained a great deal of knowledge and experience by successfully developing and marketing a number of new products. Van Dijk heating has a dedicated Development Department for the innovation of technical products. Based on scientific information, this department is also able to provide clients with the best possible advice on the uses possible for our products in modern greenhouse horticulture businesses. Armed with your wishes and requirements, we can provide you with an appropriate design and equipment that can easily be integrated into any system.

High quality

Van Dijk heating produces its products in-house and safeguards quality by working solely with the very best high-quality materials. A completely new ERP system was bought and put in place to aid this process in 2012.

The entire product package here at Van Dijk heating complies fully with all of the relevant inspection requirements in the Netherlands and abroad and can be used throughout the world. Van Dijk heating is ISO 9001 certified and has attained the HortiQ BRL 8001 quality system certificate for ‘Companies in the greenhouse construction sector’, which is the quality system for suppliers to the greenhouse horticulture industry. As you will have come to expect from Van Dijk heating, all of our equipment carries the CE quality mark, which means that it is in compliance with all relevant European directives.

We have also attained the GOST-R certificate, which makes it possible for us to import our products into Russia.

Service 2.0

We sell our products to the greenhouse horticulture industry via installation and greenhouse construction companies. Some products, like our retarders, are usually sold directly to boiler manufacturers.

Wherever possible, we supply orders ‘just in time’, so that clients receive our products exactly when they need them. We are proud to say that our packaging can be adjusted in line with the wishes and requirements of the individual client too.

Van Dijk heating has its own service department, which helps installers and clients to install and maintain our equipment, here in the Netherlands and abroad.

To summarise: we are an innovative engineering and trade organisation that focuses on the horticulture industry in particular and industry in general. We continually strive to improve our products and increase energy efficiency for our clients.

Since the foundation of the Van Dijk heating company, it has successfully developed and marketed a number of products. These early products are still being produced in-house by the company to this very day. They form the basis of this organisation, which looks towards the future armed with the knowledge and experience it has gained over the course of its history.

In 1975, ‘Mr.’ P. van Dijk, the founder of the company and the person who gave it his name, started to produce retarders in horticulture premises in Nootdorp. Retarders are eddy-current strips that increase the turbulence of flue gases in boiler flame tubes, resulting in improved heat transfer.

Following the oil crisis in 1973, the price of gas increased significantly and horticulture businesses 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 to 3 %. Today, Van Dijk heating is still producing large numbers of retarders, primarily for boiler manufacturers in Europe.

Further growth

At the end of the 1970s, the development of a flue gas condenser made it possible for the company to achieve further growth. Because of the ribbed-tube construction, it is possible to use the Van Dijk heating flue gas condenser to utilise the condensation heat generated by the flue gases and, by doing this, achieve high energy savings. During and after the oil crisis in 1979, this flue gas condenser was used to realize a large market share and the company’s foundations were strengthened.

At the beginning of the 1980s, the horticulture industry made a cautious start with the dosing of CO2 from boiler flue gases. At this time, Van Dijk heating introduced a CO2 set with a plastic ventilator, which made the working life of the CO2 unit to become virtually unlimited. By supplying guaranteed high-quality products and by advising on and producing calculations of the systems appropriate for clients’ needs, Van Dijk heating is now the market leader in the field of 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 pressure from environmental requirements and the introduction of cultivation on substrate. Van Dijk heating developed the ECOSTER series of drainwater disinfectors in response to this situation. The heat-based drainwater disinfection system is a simple one and the only system to guarantee 99.9% disinfection.

Demand for energy-saving equipment in the greenhouse horticulture industry, with the object of achieving a reduction in the cost price, is continuing to make itself felt today and resulted in the market introduction of the Van Dijk heating HRW boiler in 2000. This high efficiency hot-water boiler features large fire tubes that make it possible to achieve heating with a low NOx value. The first series produced were water tube boilers (type HRW), while the later series were flame tube boilers (type HRWB).

Innovative developments

Conditioned cultivation facilitates energy savings and the achievement of a better cultivation result. One of the aspects involved in this type of cultivation is the dehumidification of the greenhouse air with relatively dry outdoor air. In 2008, Van Dijk heating developed the Active Ventilation System (AVS) in response to this situation. This system makes an active contribution to an improved greenhouse climate, with energy saving and increased efficiency as a result. In 2012, this product group was extended to include the AVS WTW, an AVS unit with a heat recovery function.
