Description
Finnleo Infrared (IR) Heating System — IS301
Finnleo's IS301 Infrared Heating System lets you transform any permanently installed residential sauna into a dual-mode wellness sanctuary. By adding a low-EMR infrared emitter panel alongside your existing traditional heater, you gain the freedom to choose between a classic high-heat Finnish session and a gentle, lower-temperature infrared session — all in the same room. Infrared heat radiates directly into the body rather than simply warming the surrounding air, producing deep perspiration at a more comfortable ambient temperature that many bathers find easier to tolerate for longer periods. The IS301 kit includes one mid-size infrared emitter panel and a contactor box, ready to integrate cleanly into your sauna's existing tongue-and-groove walls.
Key Features
- Residential retrofit for existing permanent traditional saunas — no structural changes needed
- Includes one mid-size IR-160-240 emitter panel and contactor box
- Low-EMR panel for confident, longer sessions
- Compatible room height: 81" – 84"
- Sized for rooms of 135 – 200 cubic feet
- Pairs with the SaunaLogic 2 IS (SL2-IS) control for single-interface dual-mode operation
- Safety-tested and listed for North American residential use
Note: An SL2-IS control is required and sold separately. Ask us to confirm this model is the right fit for your room.
