Dear Friends
In the coming weeks we have to start up a Freezer 60mx60mx12m which will work at room= -28șC

It is conected to a two state ammonia system.
low SST =-35șC, media SSt=-5șC, Condensing at 35șC

We will use the SST= -5șC to keep the dock room at +5șC.

How do you recomend to handle the start up?
Which commpressors should we start first?
How many steps we should use to low the temperature in the freezer?
What conditions will difine to go to the next step?(temperature or RH)
I appreciate your very kind comments
regards
Gwapa
