Hey.
Design systems with free cooling option. (saves a lot of power)
Heating element in compressors.
Control of condenser fans, for high enough condenser pressure at low outdoor temperatures.
Which company do you work for?
Regards
Kay

Re: Refrigeration system in cold countries
You say that there is a propylene-based cooling system......
Is it a water cooled evaporator and air cooled condenser?
What temperature should you have on the water? 7/12 degrees?
I must know a little more about the system design to make recommendations, but maybe that it's a secret :-)
