www.alfalaval.com 1 Metal casing instead of plastic lateral sides
www.alfalaval.com 2 Lateral drip tray stronger and more industrial
www.alfalaval.com 3 improve easy access to coil for cleaning
www.alfalaval.com 4 reduce number of fixing points …3 against 5 of the previous version
www.alfalaval.com 5 more space for expansion valve installation
www.alfalaval.com 6 easy change for defrost rods This is still valid on the 300 since the rods are just in the drip tray. CD400 models will have rods also in the coil due to a wider geometry and a bigger surface
www.alfalaval.com 7 precut frame for maximum versatility (connections) 8 horizontal drain connection to reduce unit height
www.alfalaval.com 9 no wiring as std fanmotors wired to a common connection box is std with EC fanmotors so always included on the 300 10 version for no packed goods (fresh): 400 is using 4812 geometry providing higher surface/kW ratio in order to fulfill this request. Many combination of fan velocity/number of fans/capacities are available in order to cope different duties 11 powder coated or Stainless steel casing: All external visible parts, rivets, brackets, hinges in SS

www.alfalaval.com Slide 30 In lijn met de berekening: overeenstemming tussen thermische balans van verdampingscapaciteit (fluxmeter & enthalpie) en warmtecapaciteit (elektrische capaciteit) The capacity balance was surprisingly good (104%) even expansion valve was adjusted twice and heat load was increased ones during the capacity measurement period. These adjustments were rather small and time period was long. Labo’s commentaar: Optigo CD Test labo Vantaa - Performantie
