Efficient car park lighting and control

The second generation of SubstiTUBE T8 Connected LED tubes have been developed for use in car parks with several points of access, factories, warehouses, and corridors.

The system solution SubstiTUBE T8 Connected from LEDVANCE allows smart lighting without programming or rewiring which can reduce time and labour costs significantly. With both the sensors and the SubstiTUBEs communicating via the new ZigBee 3.0 standard, large groups of up to 200 devices – tubes and sensors – can be wirelessly controlled to extend presence detection and the corresponding automated lighting to cover large areas. For example, with sensors located at several entrances and exits, the tubes can be automatically turned on in sync if someone enters the premises. Therefore, the system is ideal to meet the specific and demanding lighting requirements in car parks.

The new SubstiTUBE T8 Connected features a master and slave mode for multizone control. The factory setting of the multi-sensor is slave mode, yet it can be configured to be a master sensor during network installation.

Thanks to multi zonal dimming, occupancy sensing and daylight ambient setting, the intelligent system of new SubstiTUBE T8 Connected and sensors achieves significant energy savings of 50 percent.

The SubstiTUBE T8 Connected comes in a glass design with shatter protection film, has a very high efficiency of up to 150 lm/W, and a lifetime of up to 50,000 hours. The tubes are available in lengths of 1,200 mm and 1,500 mm with a fiveyear guarantee.

The LEDVANCE Connected Sensors come in two variants for different installation heights: LB (Low Bay) for heights up to 4m and HB (High Bay) for heights from 4 up to 14m. ONLINE ENQUIRY 106

Easy to operate current transformer

Portable electrical test equipment supplier Megger has launched the MVCT, a current transformer (CT) tester with the option to test voltage transformers. It offers industry-leading test speeds for CTs, easy operation via a colour touchscreen and the convenience of having VT and CT test facilities in the same unit.

The MVCT can be directly connected to multi-ratio CTs and will perform a full sequence of tests on up to five taps automatically, at the touch of a button, without the need to change the test lead connections. This feature provides enormous time savings compared with conventional instruments where each tap has to be tested separately.

The instrument’s large colour touchscreen makes it easy to perform automatic testing using pre-constructed test routines as well as manual testing for special cases. ONLINE ENQUIRY 107

Next generation magnetic dirt separator

Spirotech has unveiled its ‘next generation’ SpiroCross featuring a magnetic dirt separator for even more efficient magnetite removal.

The SpiroCross XC-M utilises magnetic field amplification to attract magnetic particles that are in the system fluid, the captured dirt then being easily removed via a 360o rotating drain valve. SpiroCross units combine three functions in one: efficient hydraulic balancing, a deaerator for the effective removal of circulating and trapped air, and dirt separation, now with the addition of a magnet in the XC-M. Rob Jacques, Spirotech’s national key accounts and technical sales manager, said: “The SpiroCross XC-M with magnet is a cost-efficient three-in-one solution designed to maximise system efficiency over the long term.” Today’s highly energy-efficient systems require optimal hydraulic balancing and can only offer best performance if air and dirt is removed from the system fluid. With the new SpiroCross design, Spirotech says it has maximised the effectiveness of the magnet by positioning it vertically in the middle of the unit, in the direct flow path.

As well as the magnet, the SpiroCross XC-M has four temperature sensor mounts, which can be used for the temperature measurement of a heating or cooling system that is equipped with an independent control system.

SpiroCross units not only help maximise a system’s energy efficiency, they save on space, and installation and maintenance costs. ONLINE ENQUIRY 105

Dual refrigerant air curtain stems losses

Mitsubishi Electric has launched a new, R32 Air Curtain which is designed to improve energy efficiency and minimise heat loss from a building while allowing businesses to benefit from an open door policy.

Developed by Mitsubishi Electric in conjunction with air curtain manufacturer Thermoscreens in the UK, and currently available in 1m, 1.5m or 2m lengths as a dual refrigerant solution (R32 or R410A), the units are suitable for businesses looking to future proof their buildings by running completely on R32. They offer lower run costs and carbon emissions through the Mr Slim Power Inverter high efficiency outdoor units.

As the first manufacturer in the UK to launch an R32 Air Curtain, the new Mr Slim HP DX 2.0 Air Curtain completes the R32 offering across splits indoor units and allows customers to move to one sole refrigerant on site.

Flexible and easier installation is achieved with the R32 indoor unit as it is available in a recessed or exposed design offering. In addition, the Mr Slim HP DX 2.0 air curtains can be used as twin systems, using two identical units to serve a wide or double entrance/exit, served by a single common Mr Slim outdoor unit.
