Bellers

The Spectrum IR Oven

PRODUCTS > BELLERS

PVC bellers thermoform a “bell” or socket on one end of each pipe.

They represent our longest-running product lines and many of our greatest innovations over the last 30 years. We offer a wide variety of bellers in a number of styles, and we stand proudly behind each one.

Below, you’ll find our two styles of solvent-weld bellers and our Rieber gasket bellers.

You’ll also find our new Spectrum IR system (pictured at right), offering short-wavelength IR heating with closed-loop PID control of bell temperature for unheard-of efficiency and bell quality.   Learn more >

Advance Solvent-Weld Bellers

Advance builds solvent-weld belling machines for pipe sizes from ½” up to 16″.

We offer two different styles: the CBM-Series and the SW-Series.

CBM-Series
Solvent-Weld Bellers

For up to 4″ pipe belling, the exclusive “Convectair” heater creates a very
simple and effective machine. It’s simpler because it delivers uniform heating without the need for pipe rotating mechanisms. Available in several size ranges, and we configure it in single, double, and quad-speed models. Some of these even deliver half of the bells at each end. CBM “Convectair” bellers set the industry standard for small pipe solvent-weld belling that is fast, reliable, and simple.

SW-Series
Solvent-Weld Bellers

For up to 16” solvent-weld pipe belling, radiant and convective heat combine in our SW series of machines. These also offer single, double, and quad-speed models. Some of these even deliver half of the bells at each end. SW 43 through SW 16.2 bellers deliver high-quality solvent-weld belling thanks to our robust, easy-to-maintain designs.

Rieber Gasket Bell 3D

Advance Rieber Gasket Bellers

Our K-Series Rieber gasket bellers build upon the CBM and SW platforms, with important features that realize the true potential of the Rieber process. Multi-zone heating, fully automatic gasket loading and lubrication, and exacting bell-length control give you the control you need, producing good bells with almost no operator involvement. These bellers also feature vacuum draw-down of the bell for a simpler process, and fully enclosed spray chamber cooling.

All our Rieber gasket bellers also produce solvent-weld bells K4: ½” – 4” pipe
K62 and K63: 1½” – 6” pipe
K82 and K83: 1½” – 8” pipe
K12.2: 4” – 12” pipe

Introducing Advance Spectrum IR Heating

Short-wavelength IR heating with
closed-loop PID control of bell temperature

Formerly too fragile, costly, and complicated, Advance now offers a robust and economical way to take advantage of the benefits of short wavelength IR heating.

By using the best MI3 sensors from Fluke Process Instrument Co., and an Allen-Bradley CompactLogix PLC, we simplify closed-loop heating. Set the temperature you want, and the quartz dual-tube emitters modulate just the right amount of heat into the bell.

Shortwave IR heating using quartz dual-tube emitters works better.
Here’s why:

1: Quartz tube emitters produce much of their energy as short wavelength IR radiation. PVC absorbs shortwave IR radiation very efficiently. Calrods just don’t emit these shorter wavelengths of energy.

2: Quartz tube emitters heat up and cool down very quickly. When they need to pump heat into the PVC, they quickly power up to full intensity. But when the bell is hot, the emitter ramps down just as fast, so it’s not putting unwanted heat into the bell. Calrods can’t react like this, taking minutes instead of seconds to respond.

Shortwave IR heating using quartz dual-tube emitters works better.
Here’s how:

Conventional radiant heating uses calrod-type elements that heat up and cool down slowly. They work fine until conditions in your plant change, but temperature and timer settings that worked at noon might not work during graveyard shift. A few bad bells later, your operator notices that the beller needs adjustment. And if breezes blows in, that can cool down the bell and the oven, causing scrap.

Your best operators can probably stay on top of these problems, if they aren’t busy with other things. Closed-loop PID control of short wavelength IR heating takes care of this automatically. A temperature setpoint of 275 degrees delivers a bell that is very close to that temperature. You can finally have uniform, predictable bell heating without constant attention, under shifting conditions and with average operators.

If there’s no call for heating, the heater ramps down, and you save a lot of energy. The heater only draws power when the bell temperature demands it. If there’s no pipe in that heat station, the heater emitters turn off until needed.

Shortwave IR heating using quartz dual-tube is more expensive… but only in the short run.   Call for more details. >
