DD24 - all fiber

Olympic DownDraft Gas Kilns are front loading and built of board, fiber and brick insulation.  Multiple venturi burners give even heat distribution to Cone 10 on low-pressure propane or natural gas with minimal maintenance.  Gas flow and reduction are easily controlled from the front of the kiln.

An ignition systems with thermocouple safety shut-off, gas pressure gauge, heavy welded hinges, and an adjustable door support wheel are standard.  Options include electronic controller, pyrometer, kiln sitter.  Stainless steel jackets are now standard. 

Olympic designs are durable and efficient, but a special feature of all our commercial kilns is the easy disassembly for repair or maintenance when that becomes necessary.

Options:

Gas Kiln Sitter System - The kiln sitter provides an automatic shut-off when the kiln reaches a specified cone temperature. The limit timer will shut the kiln off at a preset time. An electric valve runs the gas kiln sitter.  Requires a 120 volt outlet.

Pyrometer - An analog pyrometer is an available option for measuring temperature of the kiln while firing. Pyrometers should be wall mounted away from the kiln to prevent damage to the instrument. Olympic's analyog pyrometer is rated 0-2500F.  Digital pyrometer can only read to 2000F but can go higher in C.

120 Volt Electronic Wall Unit - Olympic's electronic wall unit features programming by cone number or allows you to create your own programs. Each program has eight segments with ramp/hold profiles and controlled cooling rate. The controller also features numerous means for diagnosing problems and convenient program review before or during a firing.  Because the electronic controller runs in an on/off mode and is not proportional, the gas kiln operator will need to manually adjust the gas flow several times as the kiln reaches 1500F, when the controller can fully automate the firing. Includes valves necessary for controlling gas flow.

Blower Burner - Forced air blower burners are available; They speed firing and are more fuel efficient than standard Venturi burners.  Note that the standard Venturi burners work extremely well by themselves

Vent Hood - The vents measure 48" x 48". Vents shipped with a kiln are palletized separately and have an approximated shipping weight of 172 lbs. You will need to purchase a double or triple walled exhaust pipe 10" in diameter to extend out of the top of the vent and through the wall or ceiling to the outside.
