Alfa Laval presenteert… een nieuw DNA...
Type batterij: C = compact Aantal fans :1, 2, 3, 4, 5 Fan diameter: 30=300mm Toepassing: E=Dx, W=Brine, X=CO2 Product Naam: Optigo CD Vin afstand : 4mm, 7mm CDE H 303C BS 230V BOP PC A – EP 4.0 CU Buismateriaal: koper Bescherming batterij : Epoxy, Cataphoresis Ventilator snelheid : H =hoog, L = laag Grootte batterij: B, C Aantal fasen : S = Single Behuizing : PC = Powder coated Alu Ontdooiing : A = Lucht, E = Elektrisch Optigo CD
The market input regarding the Optigo CD30C & 300: •Capacity range should be extended •Fans AC & EC should be available •Smaller height for the small (compact) models •Price competitiveness •Better overall quality (plastic side panels too poor) Market feedbacks from 2012 version
Product care project scopes N°Request 1Metal casing instead of plastic lateral sides 2Lateral drip tray stronger and more "industrial" 3Improve easy access to coils for cleaning 4Reduce number of ceiling fixing points 5More space for expansion valve installation inside unit 6Easy change for defrost rods 7Precut on frame to allow maximum versatility 8horizontal drain connection to reduce unit height 9No electrical connection as standard on big units 10Version for no packed food application 11Only powder coated or inox to avoid color difference
1 Metal casing instead of plastic lateral sides
2 Lateral drip tray stronger and more industrial
3 improve easy access to coil for cleaning
4 reduce number of fixing points …3 against 5 of the previous version
5 more space for expansion valve installation
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
7 precut frame for maximum versatility (connections) 8 horizontal drain connection to reduce unit height
9 no wiring as std fanmotors wired to a common connection box is std with EC fanmotors so always included on the 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
Height of the unit: comparison with PolarCat Duo unit 16 cm the body 19 cm body+ drain Low height -> selling point!
Height of the unit: comparison with PolarCat Duo unit 18 cm the body 21 cm body+ drain Low height -> selling point confirmed!
Optimized distribution 1)Enhance proper turbulence 2)Allows HG defrost connection
Modifications: what are the differences with 2012 version?
CD 300 CD30C CD300 in details: • Casing is in aluminium powder epoxy coated; no more plastic is used • Tube: we now use 10mm tubes, instead of 8mm (for E and W, of course X remains with 8mm) •Fan: same as before! 300, 35W, like the one used on CS300, just EC (no AC available), prewired to a common connection box
CD 400 CD300 CD400 in details: • Casing: aluminum powder epoxy coated; no more plastic • Coil: we use the same coil of actual BF, so 4812 for E and W (of course X sis with 3008) •Fan: same as actual BF 400 AC; EC single phase available
Geometries sum up: CD300CD400 E X 3008 W Platform design:
Optigo CD range USP’s Easy to install thanks to: Few fixing points One central drain Prewired (when EC fanmotors are requested, so std for 300) Side space for proper valve mounting Easy to inspect thanks to: Hinged drain panels All parts screwed, no rivets on openable parts EC fanmotors as optional (2 cables +1 for low speed) CO2 dedicated range design pressure 80 bars or 42 (ongoing) Premium finishing thanks to full powder epoxy coated casing
Slide 29 •Performantie •Gedrag koeler •Ontdooiing & Waterafvoer Optigo CD Test labo Vantaa
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
Slide 31 In lijn met de regels van de kunst : •Geen ijsvorming op capillairen •Ijsvorming op bochten, behalve de laatste, welke in oververhitting werkt •Gelijkmatige ijsvorming op lamellen Optigo CD Test labo Vantaa – gedrag koeler
