We are taking over a three story office building with a parallel air cooled chiller setup on the roof. 2 (30GT---50). They have a central fan on each floor and use the ceiling as the RA.
Each zone uses a Redd 1 fan box with 2.5kw electric heat. All the controls are pneumatic. The building is about 10 years old.
I started researching the building the other day. We are in the process of getting all plans and maintenance records.
Where can we go to get some training on pneumatics?
I found a couple air leaks. How reliable are pneumatic controls?
What kind of maintenance is needed and how often?
What can we expect to fail?
Seems to me any type of digital control system would have been much more reliable and easier to monitor.
This is a manufacturing plant we have been providing service to for about 20 years. This was the only building on the property we did not maintain. They have been asking for a couple years for us to take the building over and I finally gave in.
