Cellasto® reduces NVH for improved elevator operation
Meet today’s standards for elevator comfort with Cellasto®. This high-performance microcellular polyurethane elastomer reduces noise, vibration and harshness (NVH) ensuring your elevators offer passengers a smooth, quiet ride.
Why innovators choose Cellasto® for elevator applications
BASF is your experienced partner in the elevator industry, providing custom-designed and safety-certified components crafted with the outstanding versatility of Cellasto®. Count on BASF’s team of global experts to help you engineer designs that meet your specifications for NVH, safety and performance.
Elevator overrun buffer
Thanks to advanced formulations of Cellasto® HD, your elevator overrun buffers will have the significantly improved ability to absorb energy. Maintain the same load range with a smaller buffer diameter or gain wider load range with keeping the diameter. Request a customized Cellasto® solution for country-specific standards.
Engine bearing
Control noise and vibration NVH produced by the elevator’s engine with Cellasto®. Cellasto offers outstanding vibration isolation and long-term durability.
Cabin isolator
Reduces the vibration of the pulley beams by decoupling the passenger cabin from the elevator’s hoisting mechanisms.
Rail isolator
Avoid the transmission of operational vibration into the building structure with Cellasto® rail isolators. Design a custom solution to fit your guide rail fixing method.
Rope buffer
Control acceleration peaks with Cellasto® rope buffers at cabin and counterweight during starting and stopping movements.
Roller guide mounts
Keep wheels in position and isolate the elevator’s passenger cabin from noticeable wheel vibration. Reduce cost and weight by a simple, customized Cellasto® solution.
