General Information:
"ELMAT" heating elements are manufactured by inserting between layers ofdielectric insulating material a resistive circuit that can be implemented usingdifferent technologies such as metal sheet incision (X-MAT® type), ink or pastedeposition (T-MAT02® type) or incorporation of resistive wires (W-MAT02® type)Consequently, very thin and very flexible elements are produced characterized bysignificant design possibilities.
Advantages:
1. Flexibility and lightness.2. Securing through direct adhesives, hooks, Velcro, vulcanization.3. Differentiation of surface temperature / power.4. Multi-circuit distributions can also be developed.5. Customized geometries.6. Integrated sensors.7. Selection of adhesive supports in relation to temperatures, type of surface andapplications.
Elements characterized by adhesives on one siderequire simple operating procedures to ensurecorrect assembly:
- the surface must be clean and grease-free.Cleaning: use appropriate solvents and de-greasing agents such as heptane andisopropyl alcohol with reference to correctapplication instructions provided on respectivepackages.- Holes, protruding screws and sharp edges mustbe carefully avoided.- The surface must be dry prior to application.- Assembly must be performed at temperaturesbetween 18 and 40°C.- Avoid application in dusty environments.- After removing the paper flap protecting theadhesive, the bonding stage may begin bypressing the part already installed with a rubber orwooden roller to eliminate any air bubbles. It isadvisable to begin from the part opposite theconnection zone and in any case always from theshortest side. Continue sliding out from below theprotection paper until the operation is complete.
Do not use the heater immediately after assembly:adhesion of the element improves progressively overthe first 48/72 hours after application.
Product storage:
The best conditions for correct storage are:- environment with temperatures around 20 °C andrelative humidity of 40-60%;- store in the original cardboard box;- avoid direct exposure to sunlight.
Technical requirements:
- Some materials of the inner sheets are magnetic.Contact our Technical Office for any questions aboutproduct specifications.- The adhesive chosen to secure the resistor isfundamental in ensuring safe use and depends on theapplication surface. The type of application must bespecified in the offer and product definition stages.- Any thermostats and temperature detection probes
must be applied in the zones with the highesttemperatures and reduced thermal exchangeconditions.- Increasing the specific load of the resistor requiresparticular attention as regards temperature controlgiven the low inertia of the X-MAT® heater.
Heater selection criteria:
Correct dimensions and appropriate choice of thefunctional system requires analysis of theenvironment where the heating element will be used,identifying the highest number of answers to thefollowing questions:
1. Material to be heated and relative quantitativeparameters.
2. Physical-dimensional characteristics of thehousing.
3. Type of heating (radiating, convection, conduction, recirculation).
4. For "ELMAT" foil heaters, specify the application methods, type of surface,presence of paint, temperature and relativehumidity levels in the event ofrefrigeration applications.
5. Systems used to secure the heater to the surface (adhesives, vulcanization,mechanical fixing).
6. Presence of external insulation.7. Thermal level (operating temperature,
cold-operation temperatures, any thermal flows).8. Time needed to reach operating conditions.9. Electrical parameters available: Volts, Watts,
Amperes, Direct or Alternatingcurrent, three-phase / single-phase).
(explosive, corrosive areas ….).12. Approvals required (VDE, UL, CSA, CE ……).13. Temperature controls: identify the need or
otherwise for temperature controls and relative type (bi-metal, potentiometer, electronic, adjustabler fixed, temperature limiters, oprobes, PT100, thermo-couples andrelative types).
