3 ELECTRICAL HEATING RESISTORS I. FLEXIBLE ALUMINIUM BRAIDED HEATERS electrical heating resistors convert electric energy into heat. Their working principle is to make a current circulate through an electric resistivity conductor in order to dissipate energy as heat. aluminium coated resistors have many industrial applications. They are used as door frame heaters to remove frost formation and prevent moisture. Also, they can be used in tubes and drainage trays. FEATURES No thermostat or plug terminals are required at their ends Easy to install Heating output is approximately 23W/ linear meter Available for 120V or 240V applications Robust, flexible and low cost Long service life NOMENCLATURE K HA-(XX)-(Y) (Y) = Voltage : 1 : 120V 2 : 240V (XX) = Length in foot : (1 or 2 digits) (HA) = Product : Flexible Aluminium Braided Heater (K) = Manufacturer : MODELS Reference Length (m) Total Watts (W) Voltage (V) KHA KHA KHA KHA KHA KHA KHA T h a n k y o u f o r c h o o s i n g o u r p r o d u c t s Rev

4 ELECTRICAL HEATING RESISTORS II. POLYVINYL (PLASTIC) COATED FLEXIBLE HEATING RESISTORS electrical heating resistors convert electric energy into heat. Their working principle is to make a current circulate through an electric resistivity conductor in order to dissipate energy as heat. polyvinyl coated flexible heating cables have been especially designed to prevent freezing around copper tubing in refrigeration systems. They provide the perfect solution for many difficult heating applications in the industry. They efficiently work under different operating conditions such as humidity, outdoors, vacuum, in presence of fungi, oils, solvents and many other chemicals. FEATURES Moisture-proof polyvinyl outer jacket No thermostat or plug terminals are required at their ends Heating output of approximately 23W/ linear meter Available for 120V or 240V applications Lightweight Fast initial heating due to being in direct contact with the matter Excellent withstand to mechanical shock, vibrations and repetitive bending No expansion or contraction within a temperature range of -236 C to 260 C NOMENCLATURE K HB-(XX)-(Y) (Y) = Voltage : 1 : 120V 2 : 240V (XX) = Length in feet : (1 or 2 digits) (HB) = Product : Polyvinyl Heating Cable (K) = Manufacturer : MODELS Reference Length (m) Total Watts (W) Voltage (V) KHB KHB KHB KHB KHB KHB KHB KHB KHB T h a n k y o u f o r c h o o s i n g o u r p r o d u c t s Rev

5 ELECTRICAL HEATING RESISTORS III. GLASS HEATING RESISTORS electrical heating resistors convert electric energy into heat. Their working principle is to make a current circulate through an electric resistivity conductor in order to dissipate energy as heat. glass heating resistors or quartz tubular resistors are formed from a resistance wire coil, located inside a vitreous silica quartz tube. FEATURES Constructed with Vycor glass for heavy duty Oxide-protected cable for a longer service of resistor Silicone terminals molded at high temperature Special terminals for GE applications Fast initial heating time of 30 to 60 seconds All glass heating resistors are manufactured under OEM specifications of length, assembly and electrical conditions NOMENCLATURE K HC-(XXX) (XXX) = Model (HC) = Product : Glass Heating Resistor (K) = Manufacturer : MODELS Reference Type Max.
