Tubular Heaters With Quality You Can See

Most large manufacturers buy tubular heating elements in bulk and assemble them to order. The trouble with this is, once an tubular element has been manufactured and sealed, you can’t see what’s “beneath the sheath.” The Heatmax difference is that we makes our own industrial heating elements in-house. We know the materials and workmanship that go into making a quality tubular heater and that is why we can guarantee it. Making our own heater elements also allows us to customize your heater’s performance to your specifications fast, without waiting on outside vendors.
