Nassenheider evaporator - original II

Nassenheider Classic II Volatile Substance Evaporator

Do you need a reliable and time-tested system for controlled evaporation of volatile substances in your hive? The modernized Nassenheider Classic II from German production is designed for practice – for beekeepers who want precise and stable evaporation, quality materials and equipment with long durability.

The key advantage is uniform and long-term evaporation for approximately 10 to 14 days. Thanks to this, there is no need to frequently disturb the colony and open the hive. Evaporation works on the principle of wicking through a wick, which helps maintain stable performance even with minor changes in ambient conditions – the device operates in the microclimate inside the hive.

Why Choose Nassenheider Classic II

The construction of this model is focused on simple operation and safety. Compared to older versions, it brings practical improvements that you will appreciate with every application:

1. Easier handling and filling
The liquid reservoir is not permanently attached to the frame – it is placed in the base. It can therefore be easily removed, refilled outside the hive and then conveniently returned back.

2. Safer transport and storage
The reservoir is equipped with a lid, which significantly reduces the risk of liquid leakage during transport. After installation in the hive, you simply place the lid in the integrated holder in the base, so it won't get lost.

3. Durable design and quality material
The evaporator is made of food-grade polypropylene – chemically resistant plastic that maintains its shape and withstands conditions inside the hive well. The result is long durability and reliable operation during the season.

Installation and Use

Assembly is quick and straightforward. You attach the evaporator base with two included screws to the bottom bar of an empty frame. Then you insert the appropriate wick, place the filled reservoir and position the entire frame in the hive – ideally above the brood nest, where there is suitable temperature and air circulation for proper evaporation.
