Bi-O Mat U

behind-the-bench heater

Concealed installation - Behind-the-bench heater with integrated vaporizer for private and commercial saunas.

The special behind-the-bench combi-heater provides two important advantages – it is 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. Very slim design - only 20 cm depth.

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.

The traditional water splashes 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 Bi-O Mat U with integrated vaporizer for flexible climate forms is ideal for private and commercial operations. Based on the proven 46.U heater construction. Very Robust, long-lasting construction. All made of stainless steel.

1,5 kW vaporizer with 5 l water tank, manual filling (auto-filling optional). Dry run protection with acoustic alarm. Dust collecting bottom tray. Integrated full-width infusion gutter. Water funnel with 1 m silicone hose. 6 m connection cable 5 x 1.5 mm² and protective safety grill included.

15 kg sauna stones included in the delivery.
