Description
Finnleo Infrared (IR) Heating System — IS601
Finnleo's IS601 Infrared Heating System lets you transform any permanently installed residential sauna in the 250–425 cubic foot range into a dual-mode wellness sanctuary. By adding a single 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 IS601 kit includes one IR-160-240 infrared emitter panel and a contactor box, ready to integrate cleanly into your sauna's existing tongue-and-groove walls.

- Residential retrofit for existing permanent traditional saunas — no structural changes needed
