We act sustainably


In our view, logistics means the perfect interplay between all the individual components of the company: From tool and vehicle fleet logistics to online material and warehouse logistics. This lets our technicians view the inventory and availability online, any time and from anywhere, or place an order directly.


We have a high-end, high-tech warehouse organisation and material provisioning system that saves time, storage room and money and makes the workflow substantially more efficient. The inventory overview, which can also be accessed remotely on the go, gives our customers great added value. It lets our customer service technicians check the availability of the required spare part at any time.
Process optimisation as part of our customised intralogistics concept guarantees process reliability and cost optimisation.

For long-term corrosion protection


The heating and refrigeration systems and district heating grids have to be filled with demineralised water. If the filling water is not treated accordingly, this can pose a warranty risk.
We fill all our systems with high-quality, demineralised water which is standardised in accordance with VDI 2035. Demineralised water guarantees that systems will be functional and have a long service life. Therefore, (external) water inspections are occurring more and more frequently. There is no need for you to perform quality control checks on-site because we have already done this for you under standardised conditions.

Demineralised water in accordance with VDI 2035
The ion exchange of dissociated, water-soluble substances in completely purified, oxygenated water (deionised/desalinated water) in accordance with DIN EN 12952-12.

Our tanker
Delivering large quantities of demineralised water to you in no time. We can deliver high-quality, demineralised water to you in our 25 m³ tanker. We can also fill up third-party systems.

IBC tanks – installed on a Euro pallet in compliance with standards
Ideal if only small quantities are required. Freshly produced and prepared water from in-house production in practical units for you to pick up. You could say it’s demineralised water “to go”.
