Sauna infrared heating technology

Sauna infrared heating technology



A little warmth often works wonders: It has been known for many years that targeted heat treatment of the back area can be beneficial, relaxing and soothing. KLAFS radiator control technology developed in partnership with the specialist company Physiotherm makes your infrared bath a very individual experience.

To ensure the infrared heat source can fully deliver its beneficial effects without excessively stressing your skin, four SensoCare sensors in the infrared radiator measure your skin's temperature during the entire program from a distance and adjust the intensity of the radiation to suit your body – very gently and completely automatically. So you can simply relax and let the pleasant warmth act on your body. This results in individual warming that is always safe.

The way it works


Because of its warming and soothing effect, infrared radiation is often referred to as "heat radiation".


  1. Relieves tension in your back.
  2. The localised heat expands the blood vessels. In this way, hardened muscle areas are better supplied with blood and loosened. In addition, your metabolism is accelerated.
  3. Thorough warming
  4. The direct penetration of heat into the body creates a pleasant feeling.
  5. Muscle relaxation
  6. Athletes especially appreciate mild warming to relax their muscles after training.
  7. Mental relaxation
  8. Infrared is not only good for the body. It also helps to relax the mind.
  9. Metabolic stimulation
  10. The entire body and all organs are stimulated to increased activity, accelerating your entire metabolism.

Additional InfraPLUS system


The additional InfraPLUS system brings the beneficial effects of infrared rays directly into the sauna for the first time – an additional cabin is no longer necessary. The infrared seat can be integrated into the existing KLAFS sauna series and blends harmoniously into the design of the sauna cabin.

InfraPLUS Seats

InfraPLUS Seats

With the InfraPLUS Seats, KLAFS offers you a modular system for installation of customised infrared equipment. Combine two infrared seat units each with a grid dimension of 80 cm. This lets you easily create your ideal infrared system: from the small basic unit with two seats, which you can install in any room, to larger versions with several rows of seats.

S1 Infrared


Retract, extend, feel the pleasant warmth: The Infrared S1 from KLAFS is always as large as you want it to be. It is available in two versions: the Infrared S1 SINGLE with one seat and 122 cm width and the Infrared S1 DOUBLE with room for two people and a width of 172 cm. It can be conveniently connected to any household socket and works with alternating current (230 V). No intervention in the electrical system prior to installation is necessary.


The prefix "infra" comes from Latin and means "below". The word "infrared" thus means that it refers to an area of electromagnetic radiation below the visible light spectrum. The infrared spectrum is invisible to us and covers the wavelength range from 780 nm to 1,000,000 nm (nanometres). Because of its warming and soothing effect, infrared radiation is often referred to as "heat radiation".

Using infrared radiation it is possible to transfer heat to the skin without physical contact. Basically, infrared radiation merely transports heat and therefore has no effect itself. When infrared rays hit the body, they are generally absorbed by the upper skin layers, converted into heat and do not penetrate further into the body. The body increases the blood circulation to the skin in order to cool it. The heat can only be transported through the blood and distributed throughout the body. The skin's heat defence mechanisms are affected the least by this form of heat transfer. Infrared radiation can be easily regulated and adapted to the skin's ability to absorb heat. This means that automatically regulated infrared radiation can be used to achieve optimum, reliable heating.
