Embedded in total greenhouse infrastructure

More and more growers acknowledge high pressure fog as a key element for an advanced greenhouse, but we are not a stand-alone item. As the source of humidity to accomplish controlled crop growth the use of our high pressure fog system is optimized via a climate control system. Our solutions are, via API interfaces, compatible with all providers. They, as well as specialists, also can provide relevant sensors to measure e.g. the Vapour Pressure Deficit of the crop or its sap flow. These can further enhance controlled crop growth. These developments advance rapidly, data driven crop growth is progressing, but a closed loop with the climate control system and sensors will give you the highest possible return on a high pressure fog system. Our high pressure fog solution will be embedded in your specific greenhouse operation.

Every greenhouse is unique, differences in constructions, different crops, different climate control elements available, but this graphic impression visualize some aspects to be taken into account for positioning the Pressfog pipeline system in your greenhouse. Where possible we aim to have the nozzles at least 0.5m above your crops. Looking from the top we aim to be as “low” as possible, taking into account crop heights, the lighting, screens and ventilation. Depending on the span width and the distances of the posts the Pressfog pipelines will get their lay out.


By using our own patented pressfog pipeline system we are capable of installing a project in a very short period of time. In addition, the pressfog system offers a guaranteed leak- proof installation mmediately after assembly. The couplings have a nominal operating pressure of 120 bars and a burst pressure of 250 bars. All couplings, accessories and nozzles used in the system are manufactured out of stainless steel 316 and therefore suitable for practically any application. MJTech is the only producer in the market who offers a five year warranty on the piping system.

The heart center, the high pressure pump unit

Nozzles, press couplings, all connected towards a high pressure pump unit which you can see as the heart center of your high pressure fog solution. For the high pressure pumps we use an A-brand supplier with chromed pump heads. All our pumps are frequency driven operated, not something others always offer, and a must do for stable high pressure. What we uniquely do is that we over dimension the require pump level more than anyone else in order to reduce noise levels and to have even more durable robust functioning of the system (we can apply shorter pulses), leading to the highest system reliability in the industry. Another part in our reliability are the filtering mechanisms we apply while feeding water from the low pressure pump to the high pressure pump; this avoids issues with nozzles getting cluttered.

For each greenhouse situation, if it’s from small compartments up to 100ha greenhouse a solution is tailored and required pumps are defined. The pumps can have a flow of 1 to 200 liters / minute and with that generate a certain cc / hour / m2 for a specific location and its local climate. By using a separate pump for each compartment, it is possible to spray several departments at the same time. All for controlled crop growth!
