EOS 46.U series

Behind-the-bench sauna heaters

Space-saving behind-the-bench sauna heaters for concealed installation behind a partition wall

EOS 46.U sauna heaters provide two important advantages - they are installed behind a partition wall with only 22 cm gap to the sauna wall, which saves a lot of valuable space in a sauna cabin. This will allow more space for sauna benches and will make your sauna look more spacious. With only 20 cm depth EOS 46.U heaters belong to the slimmest models on the market today.

The concealed installation ensures at the same time increased safety in use - the heater cannot be accidentally touched while it is hot. A special safety grill mounted along the top edge of the partition wall effectively prevents objects from being dropped down on the heater. EOS 46.U heaters have been tested and approved for safety and compliance with the latest European norms.

The traditional sauna infusions are of course possible. Every heater includes a water funnel with the connection hose. Thanks to the special gutter inside the heater, the water is spread across its full width for a quick and effective evaporation.

The EOS 46.U series is ideal for private and commercial operations. Very robust and reliable. Inner and outer shell made of stainless steel. Dust and water collecting tray at the bottom. Includes protective safety grill and sauna infusion kit.

The Bi-O variant for flexible sauna climate settings is additionally equipped with an integrated vaporizer. Manual filling (approx. 5 liters). Integrated dry-run protection and acoustic water shortage warning.
