Control and Heating Systems

Wet Dog Glass equipment includes full control systems as standard on all equipment. If you’re looking to build your own oven but need help with the electrical system, or have an old furnace that’s in good shape but needs updated safety to meet inspection, we can help!

Electric controls systems usually consist of just the control panel wired to the heating elements.  Elements can be designed for your oven to minimize warping over time and have a long life .

Combustion controls consist of several different systems that work in tandem together. This includes a temperature and flame safety control panel, gas safety system, variable speed combustion air blower, gas/air mixer, and burner head.

Wet Dog Glass can also provide design, fabrication, and assembly of custom control systems for any heating or control need.  This includes door switch add-ons for ovens without them, ventilation interlocking and control, and more.

Electric Systems

Control panels for electric equipment feature temperature control, ramp and soak profiling, over-temp cutoff and door switch cutoff. We use SCR or SSR (Solid state relay) power controllers to switch the elements on and off, allowing for precise control. A dedicated mechanical contactor ensures that power is disconnected when the doors are opened, or if too high of a temperature is reached. These precautions provide safety to the user as well as the equipment.

Elements can be made to fit any oven and provide the heat you need. Wet Dog Glass can provide the exact element you need for your use, or help you pick and size the correct element. We make the majority of our elements in house, and if that isn’t quite the right we can order in the element you need.

Control panels are available for use with any voltage and phase, depending on the size of equipment they need to power. Price can vary significantly depending on available electrical supply and equipment needs.  Please contact us for quotes specific to your needs.

An Electric Control Panel for a 20 cu. ft. oven is about $3,600. Most 20 cu. ft. ovens would use 6 elements, which cost about 90$ each.

Combustion Systems

If you are planning to build your own furnace, glory hole, garage or more we suggest the kits below. These provide all the specialty components and systems you need. Bricking and casting a furnace or glory hole is well within the means of many shops and individuals but a safe, precise, and efficient control and combustion system is a hard nut to crack.

By providing a full kit, we can do the bulk of the assembling and testing in our shop, ensuring you get a systems that works, is easy to install, and meets the safety codes that are getting stricter every year.

Our gas equipment typically requires 18-28″w.c. (.6-1psi) of gas pressure.  Lower pressures can usually be accommodated.

  • ThermJet System, Typical for Furnaces
  • Proportional Mixer System, Typical for Glory Holes
  • Injector System, Typical for Garages

This kits include: Thermjet burner, Control Panel, Gas Safety System, Variable Speed Blower, butteryfly valve and thermocouples. We assemble, wire and plumb most of the components and mount them on a modular bracket. You’ll still need to make the final plumbing and electrical connections to the burner for gas and air. A hot air recuperator package is an additional option.

We use different sizes of this kit for furnaces from 100-1000 lbs.

Prices start at approximately $12,000 for a full kit for a 100-200lb furnace

This kit includes: Proportional mixer, control panel, gas safety, variable speed blower, round burner(s), and thermocouples. We assemble, wire and plumb most of the components and mount them on a modular bracket. You’ll still need to make the final gas and air plumbing connections between the components on the modular bracket and the burner system.

We use different sizes of this kit for glory holes from 9" diameter to 21" diameter.

Prices start at approximately $8,000 for a full kit for a 12" diameter GH

This kit includes: Venturi mixer/injector, sticktite burner, on/off control panel, and gas safety. We assemble, wire and plumb most of the components. You will still need to mount this to the equipment and make the final plumbing and electrical connections.

We use different sizes of this kit for pipewarmers and garages

Prices start at approximately $2,800 for a full kit for a 15" opening pipewarmer.
