Cromartie have been building kilns in the heart of Stoke-on-Trent since 1946. Over that time, Cromartie have tested different approaches to kiln building and insulation. The range has included Workhorse, Studio Craft and Hobbytech kilns, alongside the CFL Premium front-loading range.
Explore the CFL Premium range below, including kiln construction features, ST215C controller information and a downloadable front-loading kiln specification sheet.

The wiring of the kiln is mounted onto a removable chassis plate which allows the contactors etc to be lifted out of the kiln to enable easy testing and replacement.
The chamber roof of the kilns are linked with K23 bricks that are well insulated and grooved. This removes any risk of a cracked roof slab as the years go by.
Traditionally the top plate is one of the worst rust-effected areas of the kiln and so can drive rust into other parts of the kiln, however as the top metal plate on our premium front loaders is stainless steel and well vented, this prevents this issue.
The slider vent system in the top plate has full stainless steel workings- there is no standard steel in the top plate area including the slider system.
The kiln roof vent slides a ceramic thick tile batt over the vent bung, where the tile is left with clearance around it so it is a loose fit with gravity always keeping a good fit to the roof vent.
The vent can be fully opened or part opened etc and the knob on the slider handle gives the user an indication of where it is. This means there is no reaching over the kiln required or dropping and breaking of vent tubes.
Metal thickness of the main frame is generally equal or 1-2 thicknesses up from others frames on the market. Our kilns are not only powder coated and oven baked on the outside, but are entirely coated on the inside to the same standard. So the thicker metal and the powder coating makes for a much longer life.
The kiln frame has extra strengthening struts under the floor, made from welded angle iron. This provides additional reinforcement and strength to the floor of the kiln, which not only stops the metal from dropping over time with the weight of a full kiln of ware and furniture but, in turn, proves a stable metal base that the side walls of the kiln actually sit on. This is unlike other manufacturers front loading kilns which rely on the span of the kiln floor metalwork to carry the weight without any "span" support.
The ST215C is a universal controller suitable for any single-zone glass and ceramic kilns equipped with a controller socket. The controller has 32 programs, each with up to 32 ramp/soak segments.
The ST215C controller supplied with Cromartie CFL Premium front-loading kilns includes a Wi-Fi interface, allowing it to connect to our server via any domestic or commercial Wi-Fi router. By logging into our Kiln Portal website (www.kilnportal.co.uk) you can view the current status of your controller. The Kiln Portal can be configured to automatically log all of your firings, capturing the time/date of the firing, details of the program used and a record of the kiln temperature history. The Kiln Portal can also be used to upload, view, edit and download programs.
The WiFi interface also comes with a USB interface which allows logging of kiln temperatures to a USB flash (thumb) drive.
The ST215C comes fitted with a plug lead and a wall mounting bracket.
