Anderson Thermal Devices’ (ATD) twin tube heaters are available in Shortwave, Fast Response Medium Wave (FRMW) and Medium Wavelengths. These unique heaters offer higher radiant energy and excellent mechanical strength allowing for longer heated lengths than available with single tube T3 or T4 lamps. Twin Tube lamps are used in the printing industry to dry inks (e.g. Heidelberg) and other industries where there is a need for mechanical strength, high energy or one-side leads.  Twin tubes lamps are also used in the Plastic Forming, Food Processing, Paint/Lacquer and Powder Coating industries.

Twin tubes are available in two cross sections: 33mm x 15mm (used mostly for medium wave applications) and 22mm x 11mm (used mainly for shortwave and FRMW applications). Twin Tubes are available with gold, or ceramic reflective coatings. Filaments can be placed in one tube or both tubes depending on the applications’ energy requirements and the leads can be on one end or on both ends of the lamp.
