The TWPro MB Rotating Cowl Ø 200 is expertly designed for use on solid fuel and gas/oil appliances, such as woodstoves, gas coal effect fires, oil boilers, and gas boilers. Constructed with precision, the outer skin is made from robust 304 stainless steel with a 0.4mm thickness, coated in a high-temperature black finish. The inner skin comprises 316-grade stainless steel, also 0.4mm thick, ensuring durability and resistance against corrosive elements.
The insulation consists of compressed rockwool with an impressive density of 200kg/m3, making it a resilient choice for various installations. Each component is fully welded, ensuring a secure and long-lasting construction. For safety, a distance of 50mm must be maintained from combustibles.
TWPro is both HETAS approved and CE marked, meeting rigorous standards with designations EN1856-1 T600 N1 W V2 L50040 G50 and EN1856-1 T200 P1 W V2 L50040 O20.
