Product News EnviroVent launches Silent Dual extractor fan
EnviroVent, one of the UK’s leading ventilation manufacturers, has introduced a new autonomous and intelligent extractor fan into its renowned Silent range, ideal for bathrooms and WCs.
S
imple and straightforward to install, the Silent Dual 100 offers dual functions, dual sensing and dual inlets, which
make it one of the most versatile and innovative extract fans available, backed-up with a full 5-year warranty. The Silent Dual 100 automatically adjusts its
performance according to the environment and ventilation requirements, via two sensors: a presence detector and a humidity sensor, making it ideal for applications such as care homes and communal residences. It also features EnviroVent’s innovative Silent motor block for quiet running. Rory Percival, head of R&D and technical for
EnviroVent, explains: “This is a major development, which brings a versatile fan with low energy consumption, low noise levels and good aerodynamic performance. We are driving forward with innovation in ventilation technology to ensure installers can offer their customers the most efficient indoor air solution.” The innovative Dual Sensing function of the Silent Dual 100 means the fan operates automatically when it detects movement (via the PIR) or a rise in humidity levels. This activates a
pre-set mode to achieve the lowest energy consumption and the lowest noise level. Designed with versatility in mind, the Dual
Function facility allows the fan to be programmed in intermittent or continuous running mode. In both operating modes, for smaller changes in
humidity, the fan incrementally increases the airflow rate until the humidity level has fallen below the set threshold, ensuring quiet and efficient operation. For larger changes in
humidity, the fan reacts accordingly to this change in its environment and operates at full speed.
The Silent Dual incorporates an intelligent
algorithm to automatically adjust its settings according to the environmental conditions, without the need for user interaction. The motor is commissioned to achieve the required flow rate, minimising the electricity consumption and noise levels to meet the exact ventilation requirement. The Silent Dual 100 is designed to operate with
very quiet noise levels, suitable for WCs and bathrooms and can be installed in Zone 1. The fan has been designed to operate in either intermittent or continuous running mode with a PIR detector, humidity sensor, backdraft shutter and airflow guide vanes as standard. The Silent Dual100 can be wall or ceiling
mounted to meet Building Regulations – Part F (England), Scottish Building Standards and Part K (Northern Ireland).

Surge protectiondevices for domestic dwellings S
The Surge Shieldrange of surge protection devices is available from specialist distributorSwitchtec.
witchtec has developed the Surge Shield series of Retrofit Surge Protection units to meet the
requirements of the 18th Edition regulations BS7671:2018. This range of easy to install enclosed surge protection devices are prewired and preinstalled in surface mounted enclosures designed to be installed in parallel to existing consumer units. Designed specifically for retrofitting where existing consumer units are installed, they provide protection for electrical appliances against surges, where it is not possible to accommodate an SPD directly within the existing consumer unit due to space limitations. These Type 2 SPD’s are suitable to installation in most domestic or commercial properties without external lighting protection systems (Lightning Rods). The range includes IP20 Metal Clad TT/TN SPD’s with either a 20KA or 40KA SPD. The standard unit is fitted with a 100A main switch, whilst other units are fitted with Type C MCB’s for additional circuit protection. Versions are also available in IP65 Polycarbonate enclosures where a weatherproof installation is needed.

The Surge Shield unitises surge protection devices manufactured by Citel, who have over 80 years’ experience in the manufacture of surge protection. The SPD’s are manufactured in accordance to IEC61643-11 and recognised by external test laboratories including EAC, IEC, VDE and cULus.
This range has been developed to meet the
requirements as detailed in the 18th Edition regulation 443.4. This requires protection against transient overvoltage’s to be provided where the consequence caused by overvoltage could cause serious injury or loss of human life, interruption of public services and/or damage to cultural heritage, interruption of commercial or industrial activity, or could affect a large number of co- inhabited people. Under other circumstances a risk assessment must be carried out to see if protection is necessary. The risk assessment calculation is based on a formula that uses values including high and low voltage overhead cable length along with high and low voltage underground cable length, plus values related to geographical location in the UK. This is information which can be obtained from the DNO, but which can be
time consuming and difficult to obtain. If no risk assessment has been carried out then protection must be provided. With the availability of such units, their ease of installation plus the complex nature of the assessment, it is therefore often easier and advisable to fit a Surge Shield SPD.
