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.
MOST POPULAR MODELS HIGHLIGHTED! *These air heaters can be operated on either 120 or 240 Volts. Specifications are shown for operation on

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.

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.

Well made but needs a pressure drop spec.
Well made heater unit per specs. It would help to add at least one data point at ambient temperature for the pressure drop thru the heater at X SCFM. Everyone knows the dP will go up when the heat is turned on so you do not need to cover this unless you want to. As my application was compressed air and I was using a few in parallel it was not a problem. The linlet max temperature told me I had to run these in parallel to get high a temperature exhaust and that worked out fine.

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.
Best regards,

Hello, to control this unit (AHP-7562), do I need an AC voltage modulator or will a normal relay style controller work for control? Basically turning the 120V power on and off as needed??? Please let me know. Thank you.
Thank you for your inquiry! You may use a controller in ON/OFF mode for this application, and most likely an external SSR or high current-rated mechanical relay. Most controller's internal relays cannot handle the high current pulled by heaters. Please see our PID controllers here: https://www.omega.com/en-us/control-monitoring/controllers/c/pid-controllers

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.
