Polyimide Film insulated (also known as Kapton ) flexible heaters are available in a variety of shapes, sizes, and wattages. Wattage ratings are 2.5, 5, or 10W/in2 at 115 or 28 V. Polyimide Film offers a high degree of resistance to chemicals. Flexible nature can fit into Intrinsic voids & can be applied very Easily

Operating temperature without PSA is -57°C to 150°C, and with PSA, these heaters operate at temperatures between -40°C and 149°C.

Typical construction consists of an etched foil element of 0.0005" or 0.0001" thickness which is encapsulated between two layers of 0.002" Polyimide Film and 0.001" FEP adhesive.

Rated 5 out of 5 by from Great adhesive and quick heatup! I bought this for a project at our company, and it does exactly what it was intended for. The adhesive sticks to what is desired very easily, and it does not want to peel off, even with lots of heat cycling. The heaters also seem to get up to temp fairly quickly. So these heaters are excellent if you want good heating times!

KHLVA-101-5-P we are planning to use this heater in our designing , Here by I have some query regrading the heater 1) what is the minimum input voltage and maximum input voltage required to drive this heater

Asked by: pooja
Thank you for your inquiry. You can use a maximum for 28V. There isn't designated minimum but of course anything less than the maximum will decrease the total wattage output.

Dear Team, We are planned to KHLVA-101-5-P in our designs ,If I give 24PWM and 0.153A to Heater, what will be the heat generated at heater side? is there any graphs related to current VS Heat generate ?? Requesting you to helps us on this !

Asked by: Pooja
Thank you for the inquiry. We do not have a way to calculate heating power in watts when a pulse driven solid state relay is used. If you apply a DC voltage at constant level then the power law and Ohm's Law can be used to calculate heating power in watts. Best regards OMEGA

Can the product be compressed between 2 platens under roughly 3000 lbs (around 10 MPa) of force?

Asked by: densewood
The specification for load on the Kapton Heaters is 5Kg/cm2 or about 71 PSI.

1. Does the Polyimide Flexible heater p/n KHLVA-101-10-P use the same adhesive backing as the SA1-RTD? 2. What is the projected lifetime of the adhesive? 3. Is a conductive epoxy recommended in addition to the pressure sensitive adhesive?

Asked by: ericl
The two adhesives are not the same but similar. The life of the adhesive depends on the environment in which they are used. If they do not exceed the rated temperature and there are no contamination, in theory, the adhesive should last a very long time. No data to provide. You can also use a thermally conductive epoxy for additional adhesion.

could you please suggest a driver which needs to drive this heater, Requesting you to helps us on this.

Asked by: pooja
Thank you for your inquiry. You can use either AC/DC 115V for KHA or 28V for the KHLV to drive these heaters.

Can I hook this product to 2--- 12V car batteries for 24V? Is there a thermostat that I could use to control the temperature with this setup?

Asked by: JKitt
You can hook batteries in series to get the Voltages to add up to 24 VDC and use the KHLVA series Heaters. The explanation of power reduction is in Jane's answer above from a year ago. There are Thermal switches that can be used to switch power on and off so visit our website to review the TSW and CCD101 products.

Can the KHLVA heaters be used with 24 Vdc?

Asked by: Off Site Eric
Yes this Heater can be used @ 24 Vdc but power will be proportionate from 28 V. Getting Power value to calculate resistance R=V^2/P (V=28 V, P specified in spec sheet) not calculating Power at 24 V. New power at 24 volt P’= V’^2/R ( where V’=24 volt, R is resistance value derived from the previous calculation). Please contact our Tech Support if you need any further assistance. Thank you.

Can this heater be safely immersed in water while operating?

Asked by: rtmcg
Thank you for your inquiry. This heater is designed for dry environments only and cannot be submersed or exposed to water.
