New doors, drives and elevators among offerings.
Transient Disturbance Filter for Elevators
CP Automation Ltd. (CPA) has launched the SineTamer® cascade system, an engineered transient disturbance filter designed to monitor all 360° of the sine wave. The product can prevent issues caused by false-zero crossings of the sine wave, reducing elevator downtime. As modern elevator software and hardware are of increasing complexity, the company says, they are more sensitive to fluctuations in power surges, even transient ones that can happen thousands of times a day.
Transient surges are a change in the fundamental frequency of power that can occur multiple times a day on the power-supply network. These surges are a result of switching operations of inductive loads, such as air-conditioning units, transformers and lift motors. A variable-frequency drive can exaggerate the frequency, leading to more transient surges, creating false-zero crossings (the instantaneous point at which there is no voltage present) of the sine wave. Devices can be falsely triggered because of fast-changing signals caused by transients, as they sense the zero point has been crossed, even when it hasn’t. It can cause confusion for all equipment on the grid.
CPA says improving management of transient surges can give both new and old elevators “a fairer chance in lasting the test of time without maintenance issues.” It has been shown to protect against a major utility-generated power surge, random failures, lockups and deprogramming of human/machine interfaces affecting elevators. “Typical surge-protection devices are unable to prevent these issues, as they are voltage-triggered only. This means built-in surge-protection systems are not a feasible option,” it adds.
Sematic C-MOD Door Now Available With Wittur ECO+ Drive
Wittur has announced the availability of the Sematic C-MOD car door with the Wittur ECO+ drive as an option. It said the new option brings together “the reliable and space-saving mechanical
structure of C-MOD and the bestselling Wittur drive” to offer distinctive technological advantages. A three-panel execution with ECO+ as an option will be announced later. As a further option, C-MOD can be delivered with CANbus connection to be included in a remote-control system for predictive maintenance. The new option shares the same fixation points of the standard C-MOD car door, so no changes in the installation procedure are required. The electronics can be installed on top of the operator or on the car roof, according to space requirements.
New Optidrive Sizes
Invertek Drives Ltd. has released the Optidrive IP66 Sizes 2 and 3, and E3 Size 5 VFD. The variable- frequency drives (VFDs) include thin-film-transistor displays as standard. The new IP66 outdoor-rated sizes bring additional opportunities for applications in harsh, outdoor situations. The Eco and P2 Size 2 are available up to 5.5 kW, with the Size 3 up to 15 kW. All Optidrive P2s provide 150% overload for 60 s. as standard, ensuring each drive is suitable for heavy-duty applications. The new E3 size will provide a power rating of up to 37k W for demanding applications. Invertek plans on OEMs to use them to reduce panel space and lower machine costs.
Elevator Lines for Low- and Mid-Rise European, African Buildings
thyssenkrupp Elevator says it is responding to the challenges of delivering customized mobility solutions in Europe and Africa by introducing two new elevator families: evolution and synergy. The completely reengineered lines have three models each, 100/200/300, and are intended for low- and mid-rise buildings for residential, commercial and infrastructure applications. Their technical enhancements include improved shaft efficiency and sustainability features. All include the thyssenkrupp MAX predictive-maintenance tool.
In addition, there are three design lines for the residential and commercial market. Each accommodates the different styles preferred in the European and African countries. They offer a range of materials like stainless steels, laminates and painted glass. Flexibility in terms of cabin size, load and speed are also intended to match customer desires.
The evolution 100 and 200 are for commercial buildings. The 100 travels with a maximum speed of 1.6 mps and a capacity of up to 1600 kg. The 200 optimizes ride comfort with low vibration, flexible dimensions and a landing accuracy of ±1 mm. It travels up to 2.5 mps and carries up to 2500 kg. The 300 is capable of the same speed and can haul up to 4,000 kg but is intended for infrastructure applications.
The synergy 100 and 200 are for residential buildings. The 100 offers an attractive option for drastically reduced shaft dimensions, both in the pit and overhead. The 200 has easily customizable cabin dimensions, and the 300 is for less-demanding commercial applications, such as schools, clinics or hotels. All models carry loads up to 1000 kg. synergy 200 and 300 are capable of a travel speed of up to 1.75 mps, while the 100 offers a travel speed of 1 mps.
