Gilberts, security fire damper

Gilberts’ GP series of perforated-face security grilles provides a solution for extract and transfer applications in high-security areas such as prisons, cell blocks and remand centres. This range of grilles is based on the preceding series and has been restyled and updated into a tougher yet still aesthetically pleasing unit. Advances in production methods and assembly make it 20% cheaper than its predecessor.

Fujitsu, air conditioning

The latest range of Fujitsu multi-split air-conditioning systems from FG Eurofred comprises a choice of two outdoor units and a new range of wall-mounted indoor units. The outdoor heat-pump units are AA rated with most combinations connected. Nominal capacities of size 14 units are 4.0 kW of cooling (EER 3.81) and 4.4 kW of heating (COP 4.31). The size 18 unit has a cooling capacity of 5.0 kW (EER 3.21) and 5.6 kW in heating mode (COP 4.18).

Legrand, electrical accessories, Part M

Legrand has expanded its Synergy range to include a selection of wiring accessories that provide style and choice for specifying within the constraints of Part M of the Building Regulations. This range has matt back plates and white interiors, addressing visibility requirements by providing a contrast between background colour, plate and device interior.

Cooper Lighting & Safety has introduced a new version of its popular Patriot bulkhead compact fluorescent luminaire in a choice of sizes and additional lamp options to complement its renowned vandal-resistant IP65 polycarbonate housing. These luminaires can be installed indoor or outdoors. They can be supplied with opal or prismatic polycarbonate diffusers and a gasket for life-long protection against the ingress of dust or water.

Aurora has introduced a GU10 replacement compact fluorescent lamp. The 11 W Luna lamp has a nano-brite coating on the reflector to achieve a light output of nearly 50 lm/W, giving an 80% energy saving over halogen. These new lamps are designed for ambient temperatures of 65°C, as found in fire-rated downlighters.

Osram, CFL

Osram now offers pin-based compact fluorescent lamps with an average life of 36 000 h to meet professional lighting requirements. The very long life of Dulux XT lamps considerably extends the maintenance cycle, leading to much lower lighting costs — particularly for luminaires that are difficult to access. Despite the long life, energy savings of 80% compared with traditional GLS lamps are achieved.

Menzies Energy Management now offers an automated meter-reading service to provide efficient and cost-effective support to commercial and industrial organisations as they move towards implementing automated meter reading, which becomes mandatory in some sectors in 201. This service includes water, gas and electricity and is based on a non-invasive data-capture device that does not require approval for fitment and eliminates the charge for utilising meter pulses that is levied by most utilities.

Mitsubishi Electric, VRF air conditioning

Mitsubishi Electric’s latest range of City Multi VRF controllers for air-handling units include a new size 500 unit that can be connected to much larger AHUs and increase the range to cooling capacities from 11 to 56 kW.

Star Refrigeration, heat pump,l DHW

Star Refrigeration has developed a heat-pump system that can generate chilled water for air-conditioning systems and ‘free’ domestic hot water at up to about 70°C. Called Envitherm, it uses carbon dioxide as the refrigerant and transcritical CO2 compression to produce high-grade heat that can raise the temperature of cold mains water to over 70°C in a single pass. Applications include buildings with a high demand for heating and hot water, such as hotels.

AO Smith, solar thermal, renewable energy, DHW, domestic hot water

A.O. Smith solar thermal systems for producing domestic hot water have a patented system to overcome the problem of stagnation in the panels. Mounted directly below the solar collector, the drain-back system avoids stagnation, when the heat-transfer fluid can overheat and start to break down. There is also no need to start the pump to get rid of excess heat when the demand for hot water is low, and no need to build in an oversized storage system to cope with excess heat.

Dimplex, domestic hot water, DHW, heat pump

The first supermarket to be built to PassivHaus standards in the British Isles includes a Dimplex ground-source heat pump that draws energy from refrigeration and cooling systems to supply domestic hot water. The Tesco store in Tramore, County Waterford, is built to very high levels of air tightness and insulation, so water heating is an important consideration in the overall performance of the building. Such buildings typically have an annual energy consumption less than 15 kWh/m2.

Douglas Delabie, TMV3, DHW, domestic hot water

The Securitherm cool-touch range of TMV3 shower valves from Douglas Delabie has been tested and certified by BuildCert to the NHS Model Engineering Specification D08/TMV3. The cool touch is achieved by passing the cold supply through an outer water channel before it is mixed with the incoming hot water. In addition, the water-supply inlets have thermally insulated covers. The shower temperature is factory set at 38°C and adjustable between 20 and 41°C.
