Profroid Condensing units

[Latte]

Evening all,

Has anyone got any information on Profroid condensing units. a collegue has been to a site today and thinks the c/u is too small. If anyone has any info on these i would help and possibly save me a drive out to it

C/U Profroid B9-R0061GCZAC Twin Fan
3 pipe pipe rise to a 25m pipe run to 2 x 1875mm wide mouth Pastorfrigo dairy multidecks

With one indoor running hp is 21 bar, with both on 25bar.

Thanks

can you please provide more details as to what refrigerant is used, your ambient temperature, plus ur LP in regards to those HP that u mentioned.

I have a lot of experience with Profroid packs and condensers but you're talking about condensing units.
Most of their condensers don't give the capacity the catalog states.
I guess you have to select for a DT of 10K to become 15K.
None of their condensers is Eurovent certified, they know why.
Same happened with the older Friga Bohn (France, now Heatcraft) condensers and evaporators.
I remember that they certified some (!) of their condensers 15 years ago and some units decreased suddenly almost 30% in condensing capacity.
You then could conclude that this could be used for their whole range.

just gone back to this site as apparently its now comming in on a daily basis.

The c/u is a profroid B9-R0061GCZAC 2006 running R404, Fitted to it are 2 low speed condenser fans model Carrier PFI0302038, Ref 023964, MTV 08M050S457-46

Does anyone have a contact for either profroid or Carrier as when i phoned them today i was told all technical is online now :-(

The condenser fans just not shifting enough heat and as soon as the ambient hits 25c the hp hits 350psi and out on hpco. I was wondering if there is a full speed fan available to fit in place of these low speed ones. I have searched online but cant find any obvious profroid or Carrier help

Regards

Latte, do you think they will admit their condensers are to small?
All these condensers have the same problem when it's becoming hot.
I should install a small PHE in the discharge and over a given HP, open a SV and allow the water pass over a pressure regulate water valve.

just condemned one of these units, compressor size is fine, condenser can't shift the heat, have replaced with a standard hermetique condensing unit. Advice now is esp. on low temp units to lower condensing pressure from factory set point of 18b to 14b, helps compressors last a bit longer!!
