Reinventing revolving doors with dormakaba

Sub-Saharan African provider of smart and secure access solutions, dormakaba South Africa, has announced the revitalisation of its KTV three-and four-wing revolving door series following the relocation of its production facilities from Germany to Bulgaria.

“Featuring numerous design variants and a plethora of optional functions, everything about KTV revolving doors have been overhauled. KTV delivers an eye-catching feature to the foyer of any business giving it a high-quality architectural appearance,” says Esmeralda Van Niekerk, Sales Manager ESA/IGS | SSA (Sub-Sahara Africa) at dormakaba South Africa.

Featuring the KT FLEX direct drive super-flat gearless and brushless drive system, the 100mm canopy doors deliver high accuracy for the optimised positioning of the sealings while providing the best movement control possible.

The German TÜV independent inspection association has tested and certified KT FLEX for two million cycles, a significant increase of the one million cycle standard requirement. This provides customers with the peace of mind that all the safety features and electromagnetic compatibility are fully compliant with international standards.

The KTV series now also comes standard with an LED light ring. This feature not only prevents unsightly dirty edges on the ceiling but also ensures the uniform illumination of the cabin regardless of the position of the door leaves. Its stainless steel floor pan protects and drains the outer floor ring half from rainwater. Meanwhile, the sheet metal shroud guides the sealing foil from the floor ring to the building foundation.

KTV doors also feature a sheet metal cover with two waterspouts and circumferential end profile that makes the range particularly safe against water penetration. It has an automatic night shield with low-energy drive and the external night closure can be manually operated and locked.

“While traditional automatic revolving doors have clearly visible sensors that take away from the design features, the KTV series features integrated sensors for both rotation start and pinch-zone safety at the leading mullions. These and numerous other advancements combine to make the dormakaba KTV series of revolving doors one of the leaders in the industry today,” adds Van Niekerk.
