2 Brug den smarte energibesparende løsning i dag! Prisen for energi fortsætter med at stige og kravene om energibesparelser øges for alle områder. Internationale miljøaftaler vil snart ændres fra vejledende til lovkrav. Energi-effektive produkter vil få deres egne klassifikationer som en del af direktivet for energi brugende produkter (Energy-using products Eup). Det er derfor en fornuftig ide at lave smarte energi effektive løsninger i dag. Valg af korrekt ventilator er økonomisk og energibesparende. Bygninger forbruger ca. 40% af alt energi inden for EU. Den samlede andel af ventilation udgør ca. en tredjedel af alt energi forbrug i bygninger og ventilatoren står for den klart største energiforbrugende del. Derfor er en korrekt dimensioneret økonomisk ventilator den vigtigste del for en optimal energibesparelse. SFP = PE/qv = kw/m 3 /s Køling 30 % Ventilation 30 % Effektivitet er den vigtigeste faktor. Det omtrentlige energiforbrug for bygninger i EU Lys og andre tekniske installationer 10 % Opvarming 30 % Den samlede effektivitet er den bedste indikator af energieffektiviteten for en ventilator. En nyttig måling er SFP (Specific Fan Power). Dette er ventilatorens samlede elektriske forbrug divideret med ventilatorens luftmængde (SFP=PE/qv=kw/m³/s) SFP målingen er et godt sammenligningsgrundlag for ventilatorer af forskellige producenter, forudsat at det totale elforbrug er udregnet ens. Når man dimensionerer det Specifikke Fan Power bør følgende overvejes: - Ventilators virkningsgrad i driftspunkt - Motor effektivitet også ved delbelastning - Hastighedsregulators virkningsgrad og dennes påvirkning af motor. Fabrikationen er certificeret i henhold til ISO 9001 og ISO standarderne 2

3 A factory-ready tested unit, which fulfils the future ErP requirements already today. Designers and product developers are set increasingly tough requirements footprint. 3 brand has become a mark of The technically advanced Centriflow Quattro fullfils Erp 2015 require - ments with ease. ready, integrated product with an awesome performance and functional - ity. Factory precision measurements are provided for every impeller size and the factory guarantees their accuracy. Existing measurement data helps the manufacturer considerably, as all the data required by the authorities already exists and the manufacturer does not need to The lifetime carbon footprint of the top efficient impeller is as small as possible. Two ways to make a more efficient air conditioning machine integrated impeller unit, it can be seen also as better SFP. (still having the same total SFP as with std-motor and std heat recovery system). Electricity saved by Quattro Heatrecovery Energy saved by Centriflow Quattro can be used at heat recovery wheels to increase the total heat benefit ratio of AHU. Heat reclaimed by heatrecovery The individually programmed frequency converter forms the central core of reliability and energy efficiency. 3

4 FW fans meets ErP regulation already now European Energy Related Products Directive (ErP) Following the Kyoto protocol the EU has set a target to reduce energy consumption by 20%, and increase the share of renewable energies by 20% by With ErP Directive the EU has defined the way to do this. Because of ErP directive for fans, fan manufacturers will be required to design their products for the European market to comply with defined efficiency standards to make an important contribution to reducing energy consumption. For this reason applicable regulations and standards have been developed for different product categories within EU. For fans with input power between 125W and 500 kw the Commission s Regulation 327/2011/EC is applied. The user can recognize fans that satisfy the requirements of the directive by the CE sign. Fan regulations The regulation sets out minimum efficiency grades for fans within this scope being placed on the market for the first time. The efficiency grade is based on the electrical power from mains and therefore encom - passes both the fan efficiency and motor efficiency. Any fan placed on the market for the first time will have to comply with these efficiency grades. For classification of fans efficiency, grade N has been generated (in international ISO standard the symbol is FMEG). Depending on the model of the fan, the efficiency grade N in accordance with ErP Directive must be complied. The efficiency grade can be measured for complete fan system or calculated by using algorithms defined within regulations. How the efficiency is calculated? The EU has specified the corresponding formulas with which the respective mini - mum efficiency for axial fans, forward and backward curved centrifugal fans, tangential blowers and diagonal fans can be calculated η e = P u(s) / P e The schedule of ErP regulations The first phase (tier 1) comes into force on the 1st January The regulation sets out minimum efficiency grades for fans within its scope being placed on the market for the first time. The efficiency grade is based on the electrical input power and therefore encompasses both the fan efficiency and the motor efficiency. Any fan placed onto the market for the first time (usually by the manufacturer) will have to comply with these efficiency grades. It will be illegal to introduce a fan onto the market after 2012 that does not comply. A second phase (tier 2) of tighter efficiency grades will come into force on the 1st January The second stage with higher efficiency values becomes effective on January 01, 2015, and this will consider the entire fan, not just the fan motor. Efficiency grades to be achieved Efficiency grade N to ErP-Diective Centrifugal fans with backward curved blades without housing with housing Centrifugal fans with forward curved blades with housing Year static static total static total How does the ErP Directive affect fans? Several models used to date do not meet the require - ments and have therefore been revised or taken off the market. It has been illegal to introduce a fan onto the market after 2012 that does not comply. 4

The new PM motor range with optimal and effi cient airfl ow through our impeller. When launched the Centriflow Plus plug fan broke the world record in efficiency, its successor the Centriflow Plus EC, broke the record again. Now our new Centriflow Plus PM puts the previous records into history and lifts the record once again to a new higher level! Taking advantage of new permanent magnet motor technology with improved motor efficiency, also having optimized the airflow through our impeller, we have improved the total fan motor efficiency by up to 6%. Improved aerodynamics with a higher overall efficiency and thus a lower power consumption, all in a smaller more compact size. Motors are available in the power range from 0.75 up to 22 kw offering airflows up to 10 m 3 /s and pressures up to 1500 Pa. The overall footprint of the Centriflow Plus PM fan is smaller due to the compact PM motor dimensions. 6

10 Det genila fläkthjulet och energieffektiv EC-motor en oslagbar kombination högverkningsgradsvariant, Roofmaster Plus EC vars total - verkningsgrad är på en helt ny nivå! Jämfört med den tradi - förbättras med över 30 %. Totalverkningsgraden baserar sig på det välkända CENTRI- - netmotor. Moderna permanentmagnetmotorer har en hög verkningsgrad och den bibehålls även då motorn körs med lägre varvtal. De övriga välkända egenskaper hos Roofmaster STEF har vi behållit. Ljudnivån är låg och Roofmaster Plus EC är lika montage - 10

11 Mångsidiga regleringsalternativ Behovet av ventilation varierar kraftigt över dygnet och årstiden. Med behovstyrd ventilation sparar man i driftskostnader. Roofmaster Plus EC har en inbyggd varvtalsregulator och varvtalet kan styras steglöst med en 0 till 10V styrsignal eller manuellt med en po - tentiometer. Det är också möjligt att köra med en eller två fasta varvtal. En tryckreglulator kan kopplas till Roofmaster Plus EC för att få konstanttryckstyrning. Tryckregulatorn kan förses med utetemperaturgivare exakt det varvtal som krävs för tillfället. Det ger en låg ljudnivå, sparar el och uppvärmningskostnader. Roofmaster Plus EC takfläkt STEC finns i fyra stor - lekar och täcker luftflöden upp till 1.7 m 3 /s och tryckökning upp till 750 Pa. 11
