GENERAL CHARACTERISTICS:
Flanged electric heaters are made for a variety of industrial applications in static air or gas heating or in forced circulation.
In addition, this type of air heater ensures optimum performance and efficiency in maintaining high volumes of gaseous fluids (air, gas, etc …).
The heating elements that make up the tube bundle can take various shapes and folds to facilitate easy installation and / or removal from the process wall, whether installed horizontally or vertically; can also be used in the direct and / or indirect heating of gaseous fluids for the most unlimited use in the main industrial sectors.
The use of high-quality materials within our production cycle allows the electric flanged electric resistances of our production to reach high operating temperatures and a medium to long-term operating life.
USE
Designed to fit in pipes, ducts or pressure tanks, whose heating surface has to be constantly coated with the air passage, this type of heaters guarantees optimum heat exchange, even in very compact dimensions.
To ensure the design of an efficient flush diving electric heater, you need to know the following technical parameters:
Among the most common applications, we find:
CERTIFIED QUALITY PRODUCT
The entire production cycle of industrial electrical resistance on flanged connections is subjected to the most rigid dimensional and electrical tests in accordance with our ISO 9001: 2008 certified quality management system and in full compliance with the requirements of current CEI / EN standards .
TECHNICAL DATA
This type of electric heaters consists of a tube bundle formed by various electric heating elements of various diameters, normally bent U or eyelets, perpendicular to the outlet of the electrical contacts or bent at 90 degrees. Each element is welded to TIG or silver alloy welded on unified DIN or ANSI flanges or on flange unity joints of variable size depending on working pressure and working temperature.
The part of the electrical wiring is housed inside standard steel or stainless steel enclosures or guards with IP55 / IP56 / IP65 / IP67 protection rating or internally with explosion-proof explosion-proof headlamps (see section “Heaters on ATEX flange “).
Equipped with efficient thermoregulators (thermostats with adjustable temperature range, automatic or manual reset, or alternatively, skin safety thermostats with cutout, PT100 thermocouples and / or thermocouples “J” or “K “), suitable for protecting the heater from overheating and any premature damage. On the board of the electrical wiring, according to the specific needs of the customer, the power inputs (NPT or GAS) are also sized according to the number of installed elements, the power and the hollow which determines the cable section .
The surface load (W / cm2) of these types of electrical resistors is appropriately determined, from time to time, depending on the conditions of use and type of fluid to be heated; In addition to these factors, the maximum working temperature and working environment are also variable which directly influences the choice of the type of sheath material with which to construct the tube bundle of these heaters (Carbon Steel, Stainless Steel AISI304, AISI309 , AISI 321, AISI 316L, Incoloy800-825, Inconel 600 or Titanium).
