The heart and sole of any infrared sauna are the heaters. Yet, so many sauna manufacturers spend very little time, effort and R&D to ensure they are providing the absolute best.
Finnmark Designs developed Spectrum Plus™ to be the best heater available to ensure you maximize every minute of therapy in your infrared sauna.
When shopping for an infrared heater, safety should be one of your biggest concerns. Would you trust the safety of your family with low quality untested heaters? Finnmark Design’s Spectrum Plus™ infrared heaters are tested by UL to be 100% safe.
Our Spectrum infrared heaters are not only extremely effective, but they are extremely low in radiation. Finnmark has gone to great lengths to protect our customers and are proud to be the only manufacturer that has taken the steps to protect against all 4 types of radiation. Electromagnetic Fields (EMF) are energy waves with frequencies below 300 hertz or cycles per second.
When evaluating a material for it’s properties to give off far infrared heat we evaluate its “emissivity”. Emissivity is the measure of an object’s ability to emit far infrared energy. Emissivity can have a value from 0 (shiny object) to 1.0 (blackbody).
Finnmark’s inconel Spectrum Plus™ heaters produce the highest emissivity of all materials used for heaters within an infrared sauna.
Watt Density is the heat flux emanating from each square inch of the effective heating area (heating surface) of the element. Watt density, expressed in watts per square inch of heater surface area, determines the heater’s operating temperature for a given set of conditions.
So many infrared sauna companies don’t calculate watt density when engineering their saunas. The result of this mistake is slow heat up times coupled with customers complaining they don’t sweat. After all, you are purchasing a device that was specifically built to make you sweat.
Finnmark spent a lot of time, research and performed many calculations to offer the most effective and highest watt density sauna on the market today. Achieving 55% more infrared heat than all competitor heaters tested.
The Spectrum Plus™ infrared heater is the only heating element that should be used in combination with a traditional steam heater. With a prestigious UL listing, this heater can withstand the harsh environments of high heat and steam without prematurely failing like carbon panels.
