We are proud to manufacture products designed to reduce heat loss during ventilation. The key term is heat recovery.
Using a heat exchanger in a ventilation system, well over 90% of the thermal energy can be recovered.
Detailed information can be found here.

Our products help you save up to 30% on heating energy. But our products themselves are also designed with the environment in mind.
For instance, we prioritize the use of recycled plastic in manufacturing our units. Even seemingly simple features—such as easily replaceable filters—help reduce waste, as they do not need to be dismantled into individual components for disposal.

Despite every effort, the manufacture, packaging, transport, and installation of a new product generate CO₂ and waste. That is why we prioritize durability in our products. After all, the longer a product can be used, the longer it is before it needs replacing. For our fans, the rule is simple: manufactured once – fresh air for many years!

#sogehtnachhaltig
Environmentally friendly manufacturing and an ecologically sound product make a great team.
But we take it a step further:
Our production and administrative buildings are equipped with—naturally—ventilation systems, heat pumps, and solar power systems, allowing us to save energy even before a single product is manufactured.
#thisishowsustainabilityworks
We do our best to generate as little waste as possible during the production and shipping of our products. This includes packaging waste. Wherever possible, we use returnable packaging that can be reused multiple times.
“I’ve always wanted to get away from paperwork. Because it’s messy. Because it annoys me to print everything out—often in triplicate—only to throw it away. That has long seemed unnecessary and pointless to me.”
Gritt Lössl, Order Processing
In January 2020, the “Paperless Office” project was launched within inVENTer’s order processing department. “Implementation actually turned out to be easy when we all had to switch to working from home due to the coronavirus.”
Since then, communication and information exchange—spanning everything from initial order processing and delivery notes to shipping confirmations and invoices—have been handled digitally and 100% paperlessly. This saves us approximately 480 kg of paper annually.

In January 2020, the project „paperless office” started in inVENTer order processing. „The implementation was easy in the end, when we all had to move to the home office due to Corona”.
Since then, communication and the exchange of information from the beginning of the order processing through the delivery note to for shipping confirmation and invoice digitally and 100% paperless. This means we save around 480 kg of paper per year.
#runs with us #paperless and #digital
We print with care and limit ourselves to printed information that we know will be used and targeted to prospects. Of course we used recycled paper. This is how we avoid waste and unnecessary print production.
Our employees are almost as happy about the trees we have planted on our company premises as are all the wild and honey bees.

Sitting is the new smoking.
Yes, we too often spend too much time sitting at work.
For us, sustainability means thinking long-term—and that includes the health of our employees.
To ensure we literally get off our backsides now and then, we organize sports events—such as the Jena Corporate Run and the Jena Team Run—as well as regular volleyball sessions on our company beach volleyball court.
But even those who aren't keen on sports are encouraged to get up and move at inVENTer, thanks to height-adjustable, ergonomic desks.
And if back pain does strike, a back massage is the perfect remedy. Once a week, every employee can—quite legitimately—bare their upper back, lie down on a massage table, and have their tension massaged away, all free of charge.
We also ensure a healthy dose of vitamins with a fruit basket that is kept well-stocked every week.

Frozen *Jagdwurst* (bologna-style sausage) with noodles in aluminum trays – when reheated in the oven, it tastes just like Grandma’s home cooking!
However, the thought of the mountains of light-metal waste—weighing around 900 kg annually—tends to stick in one's throat.
That’s why, as part of the 2019 "inVENTer Goes Greener" sustainability competition, a group of colleagues campaigned to challenge the supplier regarding the aluminum meal trays and to limit orders to meals delivered in 100% compostable Biopap trays.
This move reduced the aluminum waste mountains to 0.0 kg per year and rightly earned 1st place in the inVENTer sustainability competition.
And because our food supplier is smart too, they have also almost completely eliminated aluminum trays from their product range since 2022.
Goodbye, mountains of aluminum waste!
