Continual technological development demands ever more innovative solutions for production processes giving high potential yield at contained costs and energy saving of up to 50%.
CRE heaters are the best specific system for the die-cast material working sectors.
These UNI EN ISO 9001-2015 standard heaters with ceramic insulation offer high quality wich fully pay back the initial investment with performance advantages.
Great thermal resistance and high insulating power characterise this material which offers great savings in the construction of electric heaters.
externally lined with ceramic fiber, these CRE heaters permit considerable energy savings and find applications in the following fields: in working plastics, in foodstuff and chemical production systems and in engineering.
The structure of CRE heaters can be completed with an external grill made of perforated sheet-steel, which in the absence of a protection casing offers effective safety in line with European accident prevention standards.
For all machines in which high precision thermal process control is essential, such as plastic extruders. all the cast-in heaters manufactured by CRE can be constructed:
• in bronze / aluminium
• with / without insulation
• with / without cooling fins
• with / without a cooling coil
• working voltage: 24 – 700 volts..
– Production technologies employed: chemical etching (etched foil), thick film, or wound wire
– uniform heat distribution
– area with different power and possibility to connect two or more circuits on the same element
– elements with single or double insulation
– temperature up to 200°c in continuous working
– total minimum thickness 0.8 mm
– the elements can be produced with a bi-adhesive in order to facilitate application on various surfaces: glass, steel, plastic…
These heaters, mainly used in working processes for plastics, are subject to stress from the corrosive action of chemical agents where the material leaves the nozzle, from frequent heater fitting and removal, and from accidental impacts caused by persons at the work station. for these critical applications, CRE nozzle heaters are robust, mechanically strong and offer a high density of w/cm. high insulation power, excellent thermal exchange, no internal hollows, and uniform heat transmission are the result of advanced construction know-how, offering performance solutions for all uses.
CRE is present in the market with a vast and competitive range of thermocouples. Rapid delivery and direct customer advice and assistance service, together with scrupulous care in preparation are the winning resources behind these products renowned by the leading companies building machines for working plastic materials in various specific industrial sectors.
The advanced construction technology of these CRE heaters make them an evolved generation capable of providing maximum performance and long life in very high power load used in reduced working spaces.
their great reliability, even in the most severe working conditions derives from the meticulous tests executed during construction, strict selection of materials from the most renowned suppliers and production process know-how a CRE cartridge heater is a guarantee of quality and efficiency which translates into a real financial advantages for the user.
Apart from the range of finned heaters, CRE offers heating batter/es comprised of the same products, mounted of frames for use in channeled systems.
customers must supply some information to our technical office so that it can size the batter/es:
– the type of q\s to heat
– the system flow rate in cu.m./h
– the thermal step to be achieved
– the power supply voltage
– the safety devices to be incorporated (thermocouple, thermostat)
– the channel sect/on
– the degree of protection for electrical connections
– the frame construct/on mater/al
– the type of material for the heaters
– the useful number of heaters…
In irradiated heating, thermal energy is transmitted through particular electromagnetic waves called “infrared rays” that transfer their radiation on hitting a colder body. On contact, a part of the radiation is reflected and a part is absorbed by the body itself.
the absorbed radiation excites the atoms and molecules producing a proportional increase in the temperature of the irradiated body.
CRE infrared ray generators are comprised of a ceramic mix casing, incorporating a special spiral resistance.
The flexible tubular heater with a round section resp. with a square section (contact surface 75%) is delivered in various sizes and can easily be bent by hand.
The outer sheath made of braided metal sleeve adapts to any shape and presses itself equally into any groove on the s urface without gaps. This guarantees optimal conduction even when under duress.
Tubular heaters are the most suitable form of direct electric heating for a wide range of process fluids. Excellent corrosion resistance is ensured by the use of various types of materials. The various mounting possibilities allow to meet the most disparate heating needs. The use of materials with a high quality standard is a guarantee of long life and good reliability of our products, which allow the systems to operate with a low failure rate.
