-mac is a clever BeMS, it ensures a building, office or retail outlet is working on both an energy efficient and cost-cutting basis.
It also goes one step further by handling businesses BIG data with ease,
collecting,
processing, and reporting your energy data swiftly. t-mac works by metering building consumption, monitoring environmental conditions inside and outside of the building and controlling HVAC and lighting.
Collecting data from various sources such
as sensors, weather feeds and metering systems, t-mac allows users to analyse the data and implement the most efficient building controls strategy for their site. Whilst also considering environmental and equipment performance and managing energy efficiency. t-mac can also operate with alerts and can inform maintenance teams about equipment performance issues to allow them to resolve any problems quickly.

pgrading its domestic hot water system from two shell-and-tube calorifiers to a compact
Spirax EasiHeat™ solution has enabled Greencore Food to Go to reduce its annual gas bill by £30,000.
The EasiHeat steam-to-hot-water system provides crucial hot water for staff at the company’s production facility at Manton Wood in Worksop, Nottinghamshire. The site employs up to 2,000 people, who produce 3.5 million packs of handmade sandwiches, baguettes and wraps each week. Staff must adhere to a rigorous daily hand-washing regime, before they start work, after every break and every time they change from using one type of filling to another due to the risk cross-contamination poses to allergy sufferers.
EasiHeat is based around a compact plate heat exchanger and provides instantaneous hot water at constant temperatures. Because it does not store water like a traditional shell-and-tube storage calorifier, which must store water at 60°C or higher to aid the prevention of Legionella growth, less energy is needed to heat the water. This enabled the Manton Wood site to reduce its annual gas bill by £30,000.
Further savings will be achieved by reduced maintenance costs. Greencore’s two calorifiers needed to be stripped down regularly for insurance inspections, a task that typically took several days. The EasiHeat system does not need dismantling for insurance inspections, substantial time and maintenance costs.
saving ‘STRONGHOLD’
Fixed probe enables remote meter reading M
ETMOTEC announces its ‘STRONGHOLD’ probes that create a physically secure interface to meter optical ports enabling attachment of modems or gateways for remote reading.
By enabling fixed use of the meter optical port the complex task of accessing a meter’s electrical communication port is eliminated. This technique also enables remote access to the many meters without an electrical communications port.
All I&C electricity meters feature an optical port with a ferromagnetic disc traditionally used for reading by hand-held computer via optical probes of low magnetic attachment. STRONGHOLD’s secure attachment is achieved by magnets with over twenty times the attraction force specified in the IEC 62056-21 standard (also known as ‘1107’ and ‘FLAG’).
‘STRONGHOLD’ probes can enable remote reading of many previously manually read meters.
The probes are high quality, competitively priced and available with connectors for modems and RS485 and other networks. METMOTEC also supplies GSM/GPRS modems with STRONGHOLD probes.
STRONGHOLD is one of a range of probes now offered by METMOTEC in IEC, PACT and USA ANSI C12.18 standards, all available with connector options for hand-held and tablet computers and phones used in meter reading.

VEGAFLEX gains boiler control approval
EGAFLEX 86 - not only technologically one of the most
advanced GWR level sensors on the market and one of the simplest to set up, it also has safety accreditations for SIL 3. Additionally, it now features boiler level control approval for automated/unmanned operation according to EN12952-11:2007- Water tube and EN12953-9 :2007 for Shell type boilers (also as a limiting device in redundancy).
It features a special compensation for the run time error in saturated steam application. This means a self- contained,
ready calibrated and
compensated device can be supplied for steam boiler level control with sensor specification capable of 400°C and 400 bar. This sensor can be installed directly inside or in an external chamber, with no moving parts to drift, wear or service, resulting in lower cost of ownership. Measurement accuracy is also unaffected by changes in water temperature,
density or
conductivity. For more information, or arrange a demo, contact VEGA at
