Very old cold store fan coil problem with pictures

[Contactor]

Hello

These pictures are from an old cold store in a hotel, all the fan motors need to be re-wired and replaced.

Someone has already had a go and there are a mixture of different fans blowing in both directions.

I am going to supply and fit four new fans.

Can anyone tell me which direction my fans should be blowing in?

With similar units I have worked on previously the coil is facing the front and the air is drawn through the fan and out of the coil into the cold room.

But this unit has the coil facing to the back so I am wondering if I should use an induced air fan so that the cold air is drawn over the coil first?

Thanks
