Direct Outside Air Cooling Solutions

Continuous investment in our design and development programmes, manufacturing capabilities and installation expertise means we are one of the UK leaders in the development of high efficiency, energy saving Data Centre cooling solutions. Our range of solutions The benefits of utilising Direct Free Cooling Equipment fromWeatherite • Use of filtered outside air for cooling, for the majority of the year • Drastically reduced running time of mechanical cooling system • Substantially increased life time of the cooling system • Extended service interval – lowering on-goingmaintenance costs • N+1 resilience achieved at much lower capital cost • Latest EC fan technology – reducing energy consumption • Latest control techniques – to reduce energy consumption even further • No additional backup system required • Full mechanical cooling back-up incorporated Our packaged, direct outside air Data Centre cooling solutions are available in DX and Chilled Water configurations and are designed to suit each specific installation - ensuring the right cooling requirements are delivered for each individual application. For larger Data Centres Weatherite Packaged External or Rooftop units can be manufactured for capacities up to 400kW, specifically designed to accommodate the client’s exact requirements. FA/DX Cooling Solutions Technical Data Performance Note: 1. Down-flow units are with return air inlet at high level. With inlet at mid level, they are the same (reduced) width as the up-flow versions. 2. Down-flow unit plinths are supplied separately and can be manufactured to suit varying floor void depths. 3. Full sound spectrumdata for each fan is available on request for noise critical installations. Our cooling units can be installed internally in the Data Centre, in a service corridor or external to the Data Centre. They can supply the air into a raised floor, duct supply or flood the room. The return air can either be allowed to exhaust from the room or drawn back to the unit for reuse or exhaust. Cold or hot aisle air containment systems can be deployed to improve the Data Centre energy efficiency even further. System options • Internal or external weather proofed versions • Left or right handed FreTec versions • Up-flow or Down-flow versions • Complete, sectioned or flat-packed for ease of installation • Reduced height unit versions • Split electrical supply options, i.e. mains / generator or UPS • Glycol run round circuit for low temperature humidity control • Electric heaters - sheathed elements tomeet capacity required • Filters - G4 standard but higher efficiency pleated panel filters available • Condenser coil air filters - G2 • Humidification • All fans are EC type. AC condenser fans available • Adjustable raised floor plinths tomatch raised floor height • Mechanical or powered pressure relief • Power consumptionmonitoring • BMS networking and interrogation options Model FreTec 08 FreTec 15 FreTec 22 FreTec 30 FreTec 45 Delta T (R/A - S/A) ∆T 10 12 10 12 10 12 10 12 10 12 Sensible Cooling Duty kW 7.6 9.1 14.5 17.4 19.4 23.2 28.5 34.3 37.5 45.0 Supply Air Temperature Range ºC 21 24 27 31 25 28 31 35 21 24 27 28 31 35 21 24 27 31 25 28 31 35 21 24 27 31 25 28 31 35 21 24 27 31 25 28 31 35 Supply Air Volume m 3 /s 0.625 1.2 1.6 2.36 3.1 Number of Supply Fans 1 1 1 1 1 Number of Condenser Fans 1 1 1 1 1 Number of Compressors 1 1 1 2 (Independent) 2 (independent) Configuration Up-flow Down-flow Up-flow Down-flow Up-flow Down-flow Up-flow Down-flow Up-flow Down-flow UnitWidth mm 1,160 1,160 1,400 1,820 1,600 2,024 2,000 2,430 2,000 2,430 Unit Height (exc. plinth DF only) (Note 1 & 2) mm 2,100 2,100 2,320 2,320 2,460 2,460 2,850 2,850 3,000 3,000 Unit Depth mm 850 850 1,100 1,100 1,100 1,100 1,050 1,050 1,350 1,350 UnitWeight kg 850 850 1,100 1,100 1,100 1,100 1,050 1,050 1,350 1,350 12 °C ..... 26 °C 12 °C ..... 26 °C 12 °C ..... 26 °C 12 °C ..... 26 °C 1 °C ..... 6 °C Model FreTec Plus 45 FreTec Plus 60 FreTec Plus 80 FreTec Plus 100 FreTec Plus 125 Delta T (R/A - S/A) ∆T 10 12 10 12 10 12 10 12 10 12 Sensible Cooling Duty kW 45 54 60.5 72.5 80 96 100.5 120.5 125 149.5 Supply Air Temperature Range ºC 21 24 27 31 25 28 31 35 21 24 27 31 25 28 31 35 21 24 27 31 25 28 31 35 21 24 27 31 25 28 31 35 21 24 27 31 25 28 31 35 Supply Air Volume m 3 /s 3.8 5.0 6.6 8.3 10.3 Number of Supply Fans 2 2 3 3 4 Number of Condenser Fans 2 2 3 3 4 Number of Compressors 2 Tandem (Independent) 2 Tandem (Independent) 2 Tandem (Independent) 2 Tandem (Independent) 2 Tandem (Independent) Configuration Down-flow Down-flow Down-flow Down-flow Down-flow UnitWidth mm 1,900 2,400 2,900 3,300 3,700 Unit Height (exc. plinth DF only) (Note 2) mm 3,270 3,270 3,270 3,600 3,675 Unit Depth mm 1,300 1,300 1,350 1,550 1,550 UnitWeight kg 1,150 1,380 2,200 2,600 3,095 12 °C ..... 26 °C 12 °C ..... 26 °C 12 °C ..... 26 °C 12 °C ..... 26 °C 1 °C ..... 6 °C FREE COOLING TECHNOLOGY + + FREE COOLING TECHNOLOGY Performance
