Product Specs

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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.

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.
