“Our propane dispenser offers quick and easy exchange of gas cylinders, and it is the most reliable on the market,” says Harold Wieldraaijer, CEO of Vendanor based in Norwegian Stryn. “But we were challenged on the reliability because the laser sensor that was supposed to read the bottle was not reliable and accurate enough. This annoyed the users and sent the owners of the machines too many error messages. We struggled quite a bit with that problem until help came. from an unexpected angle.”
Grete Omre Henriksen is a product engineer at HF Danyko. She approached Vendanor because she saw it as an interesting development and production company with exciting ambitions and clear ethics. She accepted the challenge of finding suitable sensors.
“We tested different types and manufacturers and finally adapted a sensor that could provide the necessary precision,” says Grete Omre Henriksen and adds: “Now the reliability has improved, so users can put their empty bottle in, get a secure reading and take out a full bottle which is precisely like the empty one.“
Vendanor’s solution paves the way for fully automatic 24/7 sales of propane cylinders.
HF Danyko understood the problem immediately
Vendanor was founded in 2013 as a spinoff from the industrial and entrepreneurial community in Stryn. The first product was the machine for exchanging propane gas cylinders, and it was ready for introduction in 2015. Already in 2016, Danish Kosan Gas came on board as one of the first customers, and therefore it was imperative to find a suitable sensor.
Harold Wieldraaijer: “Grete from HF Danyko understood the problem immediately and simply went for a solution straight away. She quickly tested the different types and with some adjustments we got the problem solved. It was the start of a good partnership, which we have since expanded. Among other things, HF Danyko also supplies cables for our production.”
The propane vending machines can either stand as stand-alone solutions or be integrated at e.g. petrol stations, campsites, and similar locations. Vendanor has put a lot of effort into the product design, and they can brand each vending machine separately to customers such as Kosan Gas and Linde Gases.
History repeats itself – this time with sprinkler fluid
Another product developed by Vendanor is a dispenser for washer fluid. It is in line with the company’s focus on sustainability and protecting the environment because it can save large amounts of plastic by allowing car drivers to simply refuel with sprinkler fluid directly into the tank instead of buying it in plastic bags or cans.
“Here we had a similar challenge because the sensor that was supposed to measure the liquid level in the machine’s tank was not accurate enough,” explains CEO Harold Wieldraaijer. “In addition to the unreliable radar sensor, the solution also required more components, so we were looking for a more accurate solution with fewer components, which should also be easy to install and calibrate. Again, Grete and her colleagues at HF Danyko came to our aid.”
“We did not have a suitable sensor in the range, so we had to do some research and be creative about solving the task,” says product engineer Grete Omre Henriksen from HF Danyko. “We found a supplier to provide a sensor that could simply be placed outside the tank and still be able to deliver the required precision. Now the contents of the tank are being recorded down to the millimetre.”
Data about the tank contents are sent via the cloud to a server so that the customer can be notified directly when it is time for refilling one of the tanks. The solution not only saves the environment from excess plastic use but also makes it possible to plan driving and to refill much better to save kilometres, fuel, and pollution.
Sustainable solutions that run 24/7
For Harold Wieldraaijer at Vendanor, it is important not to compromise on requirements such as ease of use, reliability, and profitability, even if you have the vision to make the world a little better through sustainable solutions that benefit the environment and climate. Even the best solution falls short if it does not work.
“At HF Danyko, they share our vision of making a difference for the environment and climate but doing so in a way where quality is highly prioritized,” says the Dutch-born CEO of the innovative company Vendanor: “They want to know everything about the concrete challenge, and when they propose components and solutions, they contribute to high-quality solutions. This makes it easier for us to be a trustworthy supplier.“
The close collaboration – also on the supply of cables, among other things – has meant that the development department at Vendanor often uses HF Danyko as a sparring partner when they discuss issues and opportunities. At the time of writing, Vendanor has sold over 700 of its unique vending machines in eight countries, and new products and new markets are underway. HF Danyko is part of the team.
