Far Infrared & Full Spectrum Sauna Heaters: Low EMF / Low ELF Sauna Technology

As a leader and innovator in the infrared sauna industry we have been manufacturing infrared saunas for over 20 years.  Over the last eight years, there has been a big debate as to whether Carbon heaters or Ceramic heaters are “better”. Carbon heaters produce high quality, long wave infrared heat, but the problem is they do not produce a lot of infrared heat – in our testing they seemed weak. Ceramic heaters are powerful and emit a lot of infrared heat, but the wavelength tended to be shorter, thus less therapeutic.

Our R&D department has ended that debate by introducing the ONLY combination Carbon/Ceramic far infrared heater. Clearlight True Wave™ Far Infrared Heaters combine Carbon and Ceramic to produce infrared heat that is unmatched.  Our heaters are comprised of micro-thin carbon fibers (1/1000th the thickness of a human hair) combined with our patented micro fine ceramic compound for higher infrared output (emissivity). We manufacture all our heaters in our own factory in a special process with the carbon/ceramic layers alternated with layers of a woven substrate which combine under high heat and pressure to make one heater at a time. This innovative process produces a heater with tremendous output and high thermal emissivity. The heater is then tested under power for several hours and measured for the electrical draw, surface temperature, and emf output in twelve locations.  All Clearlight Sauna® models utilize our True Wave™ Far Infrared Heaters.

We also developed the first and only virtually no-EMF combination carbon/ceramic heaters. This patent pending process allows us to cancel out virtually all of the EMF (electromagnetic fields).

Using a laboratory grade EMF meter and measuring directly on top of our True Wave heaters, our heaters have an average EMF output of about 2.5 milligauss (mg). Compare that to over 100mg for most of our competitors carbon based heaters. In addition, when we test where you are sitting in the sauna, there is virtually no EMF.

TRUE WAVE™ FAR INFRARED HEATER ADVANTAGE

The larger size of our True Wave™ Far Infrared heaters mean more surface area, resulting in lower surface temperature. The result of this low temperature is that our heaters produce more FAR or LONG wave infrared heat. This means better performance within the optimal wavelength range of 6 to 12 microns with a large portion of wavelengths at 9.4 microns.

WHAT TO LOOK FOR WHEN CHOOSING A FAR INFRARED HEATER

We understand the difficulty in choosing an infrared sauna and trying to determine which heaters will work best for you. The following are a few questions to ask when comparing various heaters:

1) What is the surface temperature of the heater?
The is one of the most important questions as it determines the size the of the infrared wavelength and the overall effectiveness of the heater. The two scientific principals that govern infrared emissions are called Planks Law and Weins Law. Both of these scientific laws have an equation with several constants and the only variable is the surface temperature of the heater. They both say that the lower the surface temperature of the heater, the longer the infrared wave.

2) Does the sauna have front and back heaters?
Many saunas on the market today leave the front heaters out or have very small front heaters for aesthetic reasons – a huge mistake in our opinion. Our Clearlight True Wave™ heaters are positioned so you are surrounded by the infrared heat. 

3) Radiant heat vs. reflected heat:
You will see many heaters on the market that are a thin, single rod with a metal reflector behind it. Generally, these heaters produce low quality far infrared heat when compared to a large flat panel far infrared heater. First, a single rod heater must run at a much higher surface temperature than a large flat radiant heater to produce sufficient infrared heat. As mentioned above, the higher the surface temperature the less effective the infrared heat will be.

GENTLE HEAT

Because of the lower surface temperature of our True Wave™  Far Infrared Heaters, sitting in your Clearlight sauna is more enjoyable. You’ll find the heat in your Clearlight Sauna® model gentler than most-  overall a better sauna experience.

OUR CARBON/CERAMIC COMBINATION FAR INFRARED HEATERS COMPARED TO OTHER HEATERS

Don’t be fooled by marketing hype and supposed studies stating only one material is better for producing far infrared heat – know the facts. 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 mirror) to 1.0 (blackbody).

Raytek, one of the leading infrared instrument manufactures has the following emissivity tables on their website. When reading the table, please note the values in 5-14 micron ranges – the “vital” range for healing the human body (the symbol μm stands for “micron”). You will see ceramic has an emissivity of .95 – the closest to a perfect black body at 1.0. That is why the patented ceramic compound that we add to our True Wave™ heaters is so important.

Please note the highlighted entry’s in the table:

Most infrared heaters used in our competitors’ saunas were designed for industrial use. These infrared heaters are used to cure the paint on cars because it heats the paint from the inside out or as room heaters. Clearlight Infrared True Wave II heaters were designed by us, specifically for use in our saunas.

Clearlight True Wave™ Full Spectrum Infrared Heaters

All Clearlight Sanctuary Sauna™ models include our True Wave™ Full Spectrum infrared heaters.  These heaters are high output infrared heaters producing near, mid and far infrared. Every Clearlight Sanctuary Sauna™ model has 1,000 watts of full spectrum infrared. That’s 25 times the power of our closest competitor.

What Is Full Spectrum Infrared?

Near, Mid and Far Infrared

Full Spectrum Spectral Analysis

The infrared spectrum is comprised of near, mid and far infrared.

Our Clearlight True Wave™ Full Spectrum heaters emit about 1/3 near infrared, 1/3 mid infrared and 1/3 far infrared.  The following are some of the benefits of full spectrum infrared therapy:

• Near Infrared is the shortest wavelength.

• Mid infrared is a longer wavelength.

• Far infrared is the longest wavelength.
