Electric air heaters heat the air before it gets in touch with water. They are ideal for whirlpools, hydro-massage lounger and mats, which are used underwater in water parks. They are equipped with a control thermostat 30-90 °C and, in combination with an air blower, are connected to the piping with a socket combination 2” IG or a rubber hose NW 60. If necessary, it is possible to install more electric air heaters, but configure them parallel to one another, not (in line) one after the other. They work perfectly for permanent and mobile facilities.
