Aiming at offering a larger number of options to the users, Surrey has made available kits
of the electromechanical and electronic commands, and Surrey Programmable and
Non-Programmable Digital command. In order to acquire the kits contact your local
authorized dealer.
We have the following usual operating pressures (average values for the nominal
ARI 210 conditions) for all units.
Again, we point out that it is mandatory to calculate the overheating and
subcooling in order to set the gas charge and to achieve the maximum output of
the equipment.
