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)

Product care project scopes

N° Request

1 Metal casing instead of plastic lateral sides

2 Lateral drip tray stronger and more "industrial"

3 Improve easy access to coils for cleaning

4 Reduce number of ceiling fixing points

5 More space for expansion valve installation inside unit

6 Easy change for defrost rods

7 Precut on frame to allow maximum versatility

8 horizontal drain connection to reduce unit height

9 No electrical connection as standard on big units

10 Version for no packed food application

11 Only powder coated or inox to avoid color difference

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

www.alfalaval.com

9 no wiring as stdfanmotors 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

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

www.alfalaval.com

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

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.
