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.

High Efficiency and great designI'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 installI 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 builtWorks 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 advertisedBought 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 tubeReally 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?
Asked by: vicky77
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.
Asked by: A Nony Mouse
Thank you for the inquiry. This heater is rated for 80 psi. Unfortunately we do not offer 2500 psi rated heater.

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
Asked by: JB101
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

Lifetime ?
Asked by: Jonh
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?
Asked by: EHSG
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.
