Centrifugal fans for the Kruger range were installed as part of the stadium’s air-conditioning system.

Fireray, optical smoke detector

When a recently installed Fireray 5000 optical beam smoke detector sounded an alarm at 8.45 a.m. because acetone had caught fire, a sequence of events was initiated that say 10 fire engines arrive within five minutes to quickly subdue the blaze. All staff were evacuated safely.

Fabbri, biomass, boilers

The Fabbri range of wood-burning workshop heaters from Euroheat can burn the waste wood that is generally available in factories and warehouses. These heaters have outputs from 20 to 410 kW and burn all types of dry wood and secondary waste wood such as broken pallets.

Wago, BACnet controller

Wago’s BACnet controller is a freely programmable modular device designed to perform a wide range of building-automation and control function — from automating individual rooms through to HVAC systems. It automatically detects all digital and analogue I/O modules connected to the system and generates the proper BACnet objects.

Hager, electricity meters

Directly connected kWh meters from Hager meet the requirements of EN 50470-3 MID regulations. This approval is mandatory if the meter is to be used for payment purposes, such as in multi-tenanted offices or retail centres. The range has an accuracy of ±1% and includes single-phase models for direct-connection up to 63 A and 3-phase models for up to 100 A.

Mitsubishi Electric’s Lossnay heat-recovery ventilation system has been reapproved and relisted for the Energy Technology List, so a business can claim the complete capital allowance in the first year on its spending on qualifying plant and equipment. Lossnay is listed under energy-saving plant and equipment.

Aereco has devised a solution for dwellings requiring mechanical ventilation that enables them to run on passive-stack ventilation for most of the time. The concept uses passive stack ventilation ducts coupled with non-permanent low-pressure mechanical assistance that is used only when the wind forces are not sufficient to ensure the required airflow. The mechanical assistance starts automatically and can be activated by a temperature sensor or pressure controller.

GE, RCBO

GE has introduced the space-saving Compact range of RCBOs (residual current breaker with overload protection) in response to the growing use of RCBOs for domestic and commercial applications. It is the same physical size as GE’s standard ElfaPlus range of modular MCBs, so it provides more cabling space in the consumer unit.

MK Electric, distribution boards

MK Electric’s Sentry range of skeleton units are spine backplate assemblies that fit within Mantel or Clifton type enclosure, essentially a kind of metal utilities cupboard, which may also contain the meter. These enclosures are particularly prevalent in social housing, which is a main area of activity under the Government’s Decent Homes Initiative.

ICS Heat Pump Technology

ICS Heat Pump Technology now offers a 100 kW air-source heat-pump package that can deliver 65°C output temperatures without supplementary heating, even in ambient temperatures as low as -12°C. Such an output temperature enables existing boilers to be replaced with minimal work being required on the existing radiator system.

Thermo-Floor, underfloor heating

Thermo-Floor’s C-2050 plastic manifold is said to be faster to install than any other manifold. Once its mounting plate has been bolted into position, assembly can begin. The manifold slots onto the mounting plate, and the internal fixtures are clipped into place.

Daikin, fan convector, Altherma

Daikin has added to the capabilities of its Altherma system for home heating and domestic hot water with a heat-pump convector that performs effectively with low flow temperatures. Its low noise levels [down to 19 dB(A)] make it suitable for bedrooms. There is a remote control with weekly timer for room temperature, fan speed, automatic or night mode and rapid heating or cooling.

Samsung, heat pump, space heating

Samsung’s Eco Heating System (EHS) provides integrated air-to-water and air-to-air heating and cooling for homes in a single system. The EHS consists of an integrated outdoor unit, indoor units (air conditioners), and a hydro unit that can be connected to water heating devices such as underfloor heating, radiators and domestic-hot-water tanks.
