Successful retrofit using AUMA PROFOX actuators

Added - 27.07.2021

AUMA PROFOX actuators are proving themselves in the district cooling network of Qatar Cool, one of the leading district cooling suppliers in the Middle East. The compact and smart actuators are installed in the district cooling network for Pearl-Qatar, an artificial island close to Doha, Qatar.

The PROFOX actuators replace actuators of a different brand which, although only a few years old, did not stand up to the process conditions. Failures in the actuator electronics were frequent, and the hard plastic gears were worn out and could no longer deliver the required torque.

PROFOX actuators proved to be the perfect solution for the requirements of Qatar Cool, thanks to their high-quality, high-precision mechanics and their innovative design. A key benefit for the customer is easy operation of the actuators via Bluetooth, using the AUMA Assistant App. This means that the actuators can be easily operated locally, even though they are installed at a height that is difficult to access. In addition, the FOX-EYE indicator light clearly shows the actuator status, even from a distance. Another key reason to opt for PROFOX actuators was their numerous feedback signals, which the customer uses for process supervision.

Five PROFOX PF Q-300 part-turn actuators are currently in operation at Cool Qatar. They control the supply of chilled water from the district cooling network to the main heat exchanger of one of the connected buildings. More are to follow.

AUMA launched the PROFOX actuator series only last year. Providing fast and precise positioning, utmost flexibility and an excellent cost-benefit ratio, the high-performance, compact actuators are suitable for all industry sectors, including water treatment, combined heat and power plants, district heating and cooling, process industries, and shipbuilding.

Penstock flow control in World’s First ‘Electric Town’ with variable speed AUMA Actuation

Added - 22.03.2021

The small Scottish town of Kinlochleven has an extraordinary claim to fame as the first place in the world in which every home was connected to electricity. That was courtesy of a 1907 hydroelectric dam project that generated power for the aluminium smeltery near the town.

Three auxiliary spillways feeding the power plant were mothballed in the late 1960s. Waterflow control specialists Aquatic Control Engineering (ACE) were subsequently tasked with the reinstatement of the spillways, as part of a new drive for local green energy. ACE chose AUMA variable speed electric actuators to drive key penstocks that optimise water flow through the dam system, increasing efficiency and reducing energy requirements.

Paul Hopkins, Managing Director, AUMA Actuators Limited, says: “This project has been an excellent collaboration with Aquatic Control Engineering. Our variable speed electric actuators allow highly accurate levels of flow control when opening and closing penstocks.  

“Maximum efficiency requires that the culvert supplying the hydroelectric station is operated ‘almost full’. This is measured by a water level sensor that signals the AUMA AC intelligent control via a control panel. The AUMA actuator drives the penstock open or closed, and the opportunity to slow the cycle as the penstock reaches the end of the close cycle introduces a degree of self-cleaning for the penstock.”

AUMA SAV variable speed actuators can both start and stop at low speed, increasing through the mid part of the actuation cycle. This means that the inrush current as the cycle starts is tiny compared with a high torque, ‘full-speed’ start. 

The generation plant operates 24/7 and the penstocks are extremely remote so a relatively simple, uninterruptible power supply is used to cover for any loss of power, significantly reducing cabling costs and the overall cost of the project.

The 6 km of concrete aqueduct and 13 km of steel pipe through which water flows to the hydroelectric station are operated to maintain ‘almost full’ flow through a box culvert at the power station end. In the early days, this was a full-time manual job, with an operator remotely stationed to raise and lower penstocks and keeping them clean. This level of intervention contributed to the plant becoming uneconomic and falling into disrepair, closing in the late 1960s. 

In 2016 the current smelter owners SIMEC, supported by Green Highland Renewables, were able to make a substantial investment to bring the hydro power plant back to full operation and boost electricity generation to 27.5 MW.

Quantum leap for AUMA Commissioning and Diagnostic Tool software

Added - 12.01.2021

A new, entirely redesigned version of AUMA Actuators Limited’s proven AUMA Commissioning and Diagnostic Tool (CDT) is now available. The new AUMA CDT version 2020 allows fast and easy setup, operation and diagnostics of AUMA actuators using a Windows laptop.

The modern user interface and comprehensive functions of AUMA CDT help to save time and cost during commissioning, maintenance and troubleshooting. Originally designed for AUMA’s own service experts, the high-performance software tool also offers most functions to registered users. These include setting of tripping torques and end positions, modification of actuator parameters and remote actuator control. The new version also allows users to create service requests and to upload snapshot files with actuator data to the AUMA Cloud for detailed analysis.

Profibus and Modbus master functions are available for control system integration. Comprehensive diagnostic functions, such as a powerful process data monitor and an I/O interface simulator, reduce service times.

The new version of AUMA CDT benefits from a fully optimised communication protocol for Bluetooth connection to the actuator, resulting in considerably faster data transmission. A new centralised AUMA user management system improves protection against unauthorised access.

AUMA CDT supports SA and SQ actuator series with AC 01.2 actuator controls as well as SGx and SVx actuator series. The new version also supports the new PROFOX actuators.

The redesign of the AUMA CDT software underpins the company’s continuous commitment to provide users with the best support tools possible for operating AUMA actuators.

A new version of the AUMA Assistant App for smartphones and tablets is also available. Version 4.0 also provides fast Bluetooth communication and supports AUMA PROFOX actuators.

AUMA CDT is available free of charge from the Software download page. AUMA Assistant App is available free of charge on Google Play and in the Apple App Store.
