APPLICATIONS
The AHP series in-line air heaters are used to heat clean, dry air or gas for baking, drying, laminating, metal working, packaging, plastic welding, preheating, sealing, soldering, shrink fitting and synthetic fabric sewing. AHP series air process heaters provide hot air and gas up to 1000°F (540°C) with infinite control by varying the voltage and/or the air flow. Closed loop control can also be achieved with temperature controllers (section P) and 'T' fittings to mount thermocouples.

*These air heaters can be operated on either 120 or 240 Volts. Specifications are shown for operation on
both 120 and 240 Volts.
†Indicates Watts per inch of heated length. Use the table above to determine minimum required flow rates.
The Watts per inch of heated length can be changed by reducing the operating voltage or by ordering a custom

High Efficiency and great design
I've bought several of these because for heating any type of non-reactive gas there really is no substitute or better product available. These have convenient NPT threads on each end (which can be complicated if you want to go to high temperatures which would melt PTFE tape) and are relatively open to allow high flow rate gas streams to pass through. Highly recommended. One tip, don't heat them when there is no flow through them. They tend to burn out easily if you aren't providing cooling power.

Simple to use and install
I purchased one of these for a project a month ago. It was for a piece of test equipment that will require at least three units in parallel. This first unit worked exactly as I expected.

Nicely built
Works as expected. Nicely built. The warehouseman operating the forklift was bringing me the package and accidently dropped it while passing it to me and ran it over. It has a slight bend in the tube, but still works great!

Works as advertised
Bought this line heater to heat nitrogen when purging refrigerant systems on aircraft. At 200w I had to use a snubber to slow the flow, but it heats sufficiently for what it is

Well-made heating tube
Really nice air heater tube that is very adjustable via voltage input. Very well made. Will use this at lower voltage to heat air going into a microscope environmental chamber. Not what they made it for, but because adjusting voltage works so well, it works fine for me for this purpose.

How to install Inline heater with Temperature controller?
Thanks for your question. The AHP-3741 is an in-line air heater with a resistive heating element - powered by 120 vac, and puts out 200 watts of power. A separate controller or thermostat is needed to maintain a constant temperature output. We offer a panel mount controller with built-in relay that can be set at a specific setpoint - part number CNi833. Along with a thermocouple for feedback, this controller can be used to limit the output temperature from the AHP series heater. Our Tech Support engineer has emailed you reference doc with more information on the controller.

What is the pressure rating for this heater? I am looking for something like this for 2500psi N2 gas.
Thank you for the inquiry. This heater is rated for 80 psi. Unfortunately we do not offer 2500 psi rated heater.
Best regards

Hi, I need something like your inline heater (please see Item# AHP-3741) to heat argon gas to 200 C-- I'm dealing with low flow rates though from 0.5 to 1 L/min Is this something you can help with, particularly off-shelf. Thank you John
Hi John,
Thank you for the inquiry. The lowest flow rate for this family of heaters is 1 CFM. These are not compatible with the low flow range you have.
Best regards

What is the wire gauge of the leads?
Thank you for your inquiry Ant1. The wire gauge of the leads is 20 AWG.

Lifetime ?
Thank you for your inquiry. Unfortunately, we do not have any life cycle or time before failure data for these products since the lifespan is based entirely on the application and environmental conditions which will not allow for an accurate baseline to build data from.

We plan to use the model AHP-7562 with 208Vac, instead of 240Vac. Would it work correctly? I estimated the output power, the wattage, at 208V to be 560 W, and the current 2.7 A. Is that correct? Do you have technical information with voltage 208V?
The AHP-7562 can be powered with 208 VAC with a reduced Heat Wattage output. In this case the 560 Watts is what would be expected but Omega does not have any data using the Heater at lower Voltages.

What is the resistance element made of? Is it exposed to the gas flow?
Thank you for your inquiry. The Exposed Resistance Element is (80%Nickel vs. 20%Chromium).

Is the AHP-7561 clean enough to use on U.H.V. systems
Thank you for the inquiry. The AHP-7561 is not rated clean for U.H.V. systems.
