DIGI I is a simple but smart solution that gives you most basic comfort functions at the touch of a button. DIGI I lets you preheat your sauna anytime within a 24 hour period, ensuring a relaxing and refreshing climate is ready when you are without having to wait. The digital touch pad is also your control for temperature, lighting and the fan. DIGI I is designed for wall or flush mounting outside the sauna.

You’ll also find keys for temperature adjustment, light and fan operation, and the high-visibility LCD display provides information in your choice 5 languages (Finnish,

Flush or surface mounted outside the sauna, Helo Digi II has a total size of 138x173x34 mm (wxhxd).



Freestanding SKLE and Laava stoves have been the standard of the industry for more than 25 years. They are suitable for saunas with a capacity of 8-24 m3. SKLE and Laava are designed for large, commercial-sized saunas. With a maximum amount of stones of 60 kg, these stoves create a pleasant and relaxing sauna experience.

Technically Laava are SKLE quite similar and only differ in the design and colours of casing. SKLE is more angular and has a shiny look, while Laava has rounded corners and a darker, stylish exterior.

SKLE and Laava stoves are controlled by separate controllers. The options are the touchscreen T2 controller with contactor case WE 14, or the digital Digi II controller with contactor case WE 4. The range also includes the analogue OK 33 PS-3 controller and the OK 33 PUi controller used with the weekly clock EK 5 P.

The top-quality design of the stoves ensures cost-effective energy use, trouble-free usage, and effortless maintenance.



The Octa stove is based on traditional technology. This stove is ideal for saunas of all shapes, and can even be placed in the middle of a sauna. Stately in appearance, Octa stoves are suitable for saunas sized from 8-24 m3.
