In greenhouse horticulture, climate systems have grown into a complex whole of high-tech subsystems with heat pumps, CHPs, heat exchangers and cold and heat storage tanks. The quality of the feed water is one of the most important factors for the service life of these systems. We advise you to look into this together with your installer.
Saving the water when repairing the dump tank
On a fresh sunny morning driving along the heat storage tank it shows a small feather of vapour Leakage! Repairing the tank seems like a simple task, but where to go to with 5,000 m3 of water and how do I get the tank refilled?
Together
Also if things go wrong
Peter Heid had been insured with Hagelunie for just a month when his
water silo burst open. A water silo inspection had been discussed upon
acceptance, but given the short time frame, this inspection had not yet
been carried out. Peter rents out his greenhouse to his brother-in-law
Simon Höfler, where he also works as a manager.
Certain of light!
Transformers are an important link in the continuity of your lighting installation. Make sure you have a backup.
The risks of new energy supplies can be limited effectively
In more and more countries, the demand for new technologies to limit fossil fuel dependence is increasing. New techniques lead to new risks. How can you safely embed this in your organisation?
We continue our activities in the UK
We would like to inform our UK clients about the effect of Brexit on UK operations. From January 1st there is a temporary consent regime in place (TPR). The EU and UK has enacted legislation which allows companies who want to continue to operate in the UK to do so for three years after the Brexit date. Hagelunie will take full advantage of this legislation.
Pay attention to LED
LED lighting is gaining more and more ground. This is due to the higher efficiency in light output and greater possibilities for choosing crop-specific lighting and energy savings. Not all LED fixtures are suitable for the conditions in the greenhouse, and that is precisely why it is important that you, as an entrepreneur, make good choices.

Not every greenhouse is suitable for crop gutters
Sometimes you hear growers talking about swapping the load for snow for the load of crop gutters. After all: the largest load of crop and gutter will be in summertime and obviously there will be no snow in summer. Although the train of thought is not strange, this is a mistake! Read more >>
