Integrating Positive Temperature Coefficient (PTC) semiconductor chips in the Relax Saunas™ marks a technological leap, setting them apart from other sauna systems. Relax Saunas™ Proprietary PTC technology provides unparalleled precision, efficiency, and safety while enhancing therapeutic benefits. Below is a detailed explanation of how the Relax Saunas™ PTC chip outperforms conventional heating elements, backed by specifications and practical advantages.


Relax PTC Semiconductor Chip: Technical Breakdown

Material Composition and Structure

Core Material: The Relax Saunas™ PTC semiconductor chip is made from barium titanate (BaTiO₃), a ceramic-based material doped with rare-earth elements like yttrium and manganese to fine-tune its electrical resistance.

Physical Characteristics: Encased in flame-retardant ceramic for durability and thermal insulation.

Operating Range:

Temperature: 104°F to 158°F (40°C to 70°C)

Voltage: Compatible with 110–240V AC

Power Output: 200–500 watts per chip

The Only Advanced Self-Regulating Sauna on the Market

At startup, the PTC chip draws more current for rapid heating. Once it reaches its Curie temperature, resistance increases to stabilize the temperature. This smart regulation allows Relax Saunas™ to reach optimal heat in 2–5 minutes vs. 15–30 minutes for conventional systems.

Uniform Heating and Airflow Distribution

Electric fans behind each chip ensure ±2°F temperature uniformity, enhanced by the inner reflective chamber. Competing systems often experience uneven heating and hot spots.

Penetration Depth Comparison

Light Type Penetration Depth
Far Infrared PTC Chip 50-120 mm (2-5 inches)
Near Infrared 20 mm (0.75 inches)
Red Light 2–5 mm

Far infrared penetrates deeper into tissue, delivering systemic benefits ideal for detox, circulation, and pain relief.

Wavelength Comparison

Light Type Wavelength Range
Far Infrared PTC Chip 7–14 µm
Near Infrared 1.2 µm – 6 µm
Red Light 600–900 nm

The 7–14 µm band is ideal for interacting with water molecules to stimulate detoxification, circulation, and inflammation reduction.

Cellular Detoxification: Releases toxins at a molecular level

Improved Circulation: Promotes vasodilation and nutrient delivery

Pain Relief: Reduces inflammation in deep tissues

Maintenance Comparison

Sauna Type Maintenance Needs
Relax Sauna 20,000+ hours of operation, no bulb replacement
Near-Infrared or Halogen Systems Frequent bulb replacement and thermal degradation
