Technical specifications
The FS version allows the Arke to sit Freestanding and exposed on a ledge. The additional cover that the FS version includes provides a neat “boxed” design.
Inside the fireplace chamber, Kratki’s signature ceramic lining enhances both combustion efficiency and long-term durability. These heat-intensifying ceramics deliver exceptional thermal performance, supporting primary and secondary combustion for a cleaner burn and maximum heat output. By maintaining consistently high temperatures within the combustion chamber, the ceramics make the fireplace easier to operate, improve heat delivery, and significantly reduce soot buildup in the flue system. Lining the chamber with ceramics provides the highest level of protection to the steel structure, extending the lifespan of the fireplace.
The body of the fireplace insert is built from high-quality, thick steel, ensuring exceptional resistance to high temperatures. Each unit is precision-welded in a shielded noble gas environment for superior structural integrity and airtight performance. Using advanced laser-cutting and CNC bending technology, every steel component is crafted with accuracy and consistency to guarantee a perfect fit and long-lasting durability.
A large, black-edged glass door frames the flames beautifully, while Kratki’s superior heat-resistant glass and air-wash system help keep the viewing window clear. For improved safety and performance, as well as to increase their lifespan, the heat-resistant glass that Kratki uses is of the highest quality.
Kratki’s signature fireplace grate design is engineered using thick cast iron, featuring re-enforced ribbing and multiple bends to maximise strength, durability, and long-term performance.
A robust steel slide-out ash box ensures easy cleaning and everyday convenience.
The Arke frame system features a robust, thick steel finishing frame designed to deflect heat and protect surrounding walls from heat damage. A discreet slot on the underside of the bottom frame allows necessary airflow to reach the fireplace.
The comfortable handle features a solid, ergonomic design with a modern aesthetic. Its perforated construction not only enhances the contemporary look but also helps to dissipate heat.
