Thermosystems offers thermo-heating jackets that are used to raise or maintain elevated temperatures of the contents in reaction vessels, storage tanks, tankers and process equipments in industries, like cement, chemicals and fertilisers, pharmaceuticals, etc. These jackets are used for heating of viscous fluids, hopper heating for removing moisture in the product, for free flow during packaging, metallurgical industries for annealing the metals, etc. The flexible electric surface of the device to be heated. They eliminate high investment and operating costs associated with steam, oil, fire wood and conventional electric heating. Some of the features include: uniform heating, highly efficient, easy maintenance, precise temperature control adaptability, long life, custom-built, etc. Technical specifications include: thickness of panel 5 to 6 mm; operating voltage of 415 v, 3-phase / 230 v ac, single-phase; watt density of maximum 6 kw/sqm for fibreglass type and maximum 7 kw/sqm for quartz type; maximum exposure temperature 350ºc for fibreglass type and 800ºc for quartz type; rtd/thermocouples / thermostats can be used to sense the surface/product temperature to control the thermo-heating panels; and cold lead is fibreglass/quartz insulated flexible nickel-plated copper conductor of suitable capacity of 1 m length.
