The most sustainable greenhouse in the Netherlands for orchids

Ter Laak Orchids, The Netherlands


Ter Laak Orchids is one of the leading Phalaenopsis growers in The Netherlands. In this project, sustainability and energy efficiency go hand in hand.

Certhon has realized the complete heat pump installation, from heat pumps to piping and from buffer tanks to underground thermal energy storage and JSK coolers. The innovative JSK cooling installation that Certhon has realized at Ter Laak contributes to optimum air circulation, works closely with the heating system, and is equipped with a link to the Aquifer thermal energy storage. The latter ensures that excess cooling is stored in winter, to be used again in summer. This efficient cooling system not only provides the new Daylight Greenhouse with the necessary refreshment but can also work perfectly with the system already in place. The coolers are placed under the orchids so that no light radiation is lost resulting in huge energy savings.

Unique results

We give every project our fullest attention. Collaborating with you and exceeding your expectations. Resulting in exceptional highlights for this project too:

Improved plant quality

The optimal air quality improves the crop quality significantly.

An optimal climate

Each JSK has temperature control and individual ventilation control, resulting in an optimal climate in each room. A part of the nursery is also provided with top coolers with air hoses.

One of the largest heat pump applications ever made in horticulture

Certhon has installed an Aquifer Thermal Energy Storage (ATES) system with three heat pumps, a cold storage tank and ten wells.

Clever air circulation

To cool the greenhouse, Certhon has installed 125 JSK systems. The JSK takes in warm air from above the crop and after being cooled down by the system, the cool air is blown out underneath the crop.

LED lighting and cooling

In this room, where the plants are ready for sale, there is no daylight. LED lighting takes over this task. We have mounted the cooling system visibly and it ensures an optimal temperature and relative humidity for the plants.

"As ter Laak Orchids, we stand for reliability and top quality, among other things, and we expect the same from our partners, which is why we have chosen Certhon for many years."
