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 IS401 kit includes one mid-size infrared emitter panel and a contactor box, sized for rooms between 175 and 310 cubic feet, ready to integrate cleanly into your sauna's existing tongue-and-groove walls.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eResidential retrofit for existing permanent traditional saunas — no structural changes needed\u003c\/li\u003e\n  \u003cli\u003eIncludes one mid-size IR-160-240 infrared emitter panel and contactor box\u003c\/li\u003e\n  \u003cli\u003eLow-EMR panel for confident, longer sessions\u003c\/li\u003e\n  \u003cli\u003eCompatible room height: 81\" – 84\"\u003c\/li\u003e\n  \u003cli\u003eSized to cover 175 – 310 cubic feet\u003c\/li\u003e\n  \u003cli\u003ePairs with the SaunaLogic 2 IS (SL2-IS) control for single-interface dual-mode operation\u003c\/li\u003e\n  \u003cli\u003eSafety-tested and listed for North American residential use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e An SL2-IS control is required and sold separately.
