ABB motors and drives save energy cooling costs
T
he Science and Technology Facilities Council (STFC) is saving a significant amount of its energy costs after fitting three ABB-Baldor direct drive cooling tower motor and drive systems to the cooling towers of the ISIS neutron source’s proton accelerator. Three
towers form part of the accelerator’s
primary water-based cooling system. Previously, the fans in the cooling towers were run at full speed using a conventional system consisting of a fixed speed AC induction motor connected by a drive shaft and disc coupling into a right angle gearbox. The ABB-Baldor system incorporates a permanent magnet (PM) motor. These are a viable alternative to conventional AC induction
motors and significant energy efficiency advantages,
deliver even
compared with the latest premium-efficiency types of motors. This higher efficiency is even more pronounced when run at low frequencies which is the case for these direct drive cooling tower motors.

he new Hawker® BSI40™ battery status indicator is the latest battery rotation system from EnerSys®. It provides users with a cost-effective solution to manage battery fleets for warehouse trucks and other mechanical handling equipment. The system enables life-long service reliability, efficiency and sustainability. It has been designed for use with the Hawker® Lifetech® HF range of high frequency chargers and can also be integrated with existing chargers by the addition of optional sensors. The BSI40 panel is suitable for wall or rack-mounting and can manage up to 40 chargers. Four panels can be networked which means a maximum of 160 chargers can be supported by a single system – more than enough capacity for most fleet users. The batteries can be configured in up to ten separate groups or families. In this way the BSI40 system can manage chargers and batteries with different specifications to provide operators with a high degree of flexibility, adaptability and scalability.

Accurate Energy Monitoring T
he Tinytag Energy Logger from Gemini Data Loggers is a safe non-invasive
tool for
monitoring power usage of entire premises or individual high- consumption equipment. portable,
This self-configuring device
can be used for spot-checks or for longer term recording of single or three phase power supplies. Recorded data downloaded
may to to identify identify times be of
peak load, to analyse energy profiles, and
power hungry or
inefficient equipment. The Energy Logger combines ease of use with accurate,
high level
performance. Logging can be initiated by the touch of a button, so users do not need a laptop to operate the device on site, and it does not require the exposure of any live wires or terminals. Non-invasive flexible coils are used to monitor the current in each phase of a three phase supply while the voltage information may be obtained via a standard 13A wall socket. The Energy Logger costs £795 +VAT. Data loggers in the Tinytag range accurately and reliably monitor environmental parameters including temperature, humidity, single and three phase power usage and CO2. Tinytags range from compact units for building monitoring to rugged, waterproof
devices for harsh, industrial and
outdoor applications. Manufactured in the UK, Tinytags help ensure that conditions can be measured, recorded, analysed and validated. Data loggers with displays can be supplied, and specialist ATEX
validated 36 units for recording conditions in intrinsically safe areas are also available. P Over and out....
For additional flexibility, external sensors in the form of probes offer easy access to awkward areas a logger cannot reach, such as pipework; or can be used for monitoring extremes of temperature such as those in manufacturing processes and cryogenic areas.
Data from the loggers is downloaded to a PC via a USB connection and viewed with the easy to use Tinytag Explorer software.

entair Pentair Thermal Management has recently been specified to provide its Raychem Winterguard frost protection and HWAT water temperature maintenance system to 20 Fenchurch Street (The Walkie Talkie) The building’s hot water services are based in a hybrid system with recirculated pipework in the risers with a single pipe on each floor to the outlets. 2500m Raychem’s HWAT-R has been used to maintain the water at a temperature of 55° degrees and 30 HWAT-ECO controllers were employed to ensure accurate temperature control, economy setback features as well as the option of a periodic legionella prevention cycle. Frost protection on the exposed pipework on the rooftop is provided by Raychem Winterguard with Eco 10 controllers. Designed by world-renowned architect Rafael
Viñoly, 20 Fenchurch Street is a visually distinctive new addition to the London skyline. The building has been constructed with maximum efficiency in mind and
