Built for industrial-scale ceramic production and professional artists alike, the Olympic Kilns DD20 is designed to meet the challenges of large-volume firing. With a 20.5 cubic foot firing space (37" W x 36" D x 43" H), this kiln strikes the ideal balance between size and operational efficiency for substantial projects.
Cutting-Edge Downdraft Design for Consistent Firing
The DD20 features a state-of-the-art downdraft system, which ensures uniform heat distribution throughout the chamber. Unlike conventional updraft kilns, the DD20’s bottom-placed intake and exhaust system provide stable, even temperatures, resulting in consistent firing outcomes. The kiln’s external chimney enhances combustion efficiency, helping maintain the perfect atmosphere for your ceramic work.
Customizable Construction for Your Unique Firing Process
The DD20 offers versatile configuration options to suit your specific production needs. Whether you’re looking for rapid thermal cycling or a more gradual heat-up and cool-down process, the kiln can be outfitted with durable brick walls for thermal retention or fiber walls for quicker heating. Its robust frame, constructed from angle iron and metal tubing, guarantees long-term durability, while the kiln’s multi-layered insulation ensures maximum energy efficiency.
Most users opt for brick construction, where the walls and floor are built with high-quality brick, while the doors and ceilings are lined with fiber to balance heat retention with firing speed. For those requiring faster cycles, an all-fiber design (except for the brick floor) provides increased firing speeds.
Easy Loading to Improve Workflow Efficiency
Optimize your production process with the front-loading design of the DD20. For large-scale operations, the downdraft car kiln option offers effortless loading and unloading via a sturdy track system. This feature allows the entire floor and door to slide in and out smoothly, minimizing the handling of your pieces and reducing the risk of damage during loading.
Upgrade Options for Enhanced Control and Precision
Take your DD20 kiln to the next level with a wide range of available upgrades. Add a digital pyrometer for precise temperature monitoring, a high-limit safety controller for added protection, and stainless-steel or galvanized vent hoods for improved airflow and safety. For even greater ease of use, consider upgrading to a rotating door or car kiln configuration, both of which simplify the loading and unloading process.
Built for Potters and Industrial Producers Alike
Olympic gas kilns are renowned for their durability and reliability, especially for high-temperature applications like reduction firing. The DD20 is a top choice for both large-scale ceramic producers and artists who need a kiln that can handle frequent, high-volume use while consistently delivering exceptional results.
Elevate Your Production and Achieve Superior Results
Investing in the Olympic Kilns DD20 Large Capacity Gas Kiln is a smart move for those looking to expand their production capabilities while maintaining top-quality results. With its advanced design and customizable options, the DD20 is equipped to meet the evolving needs of your ceramic business.
