I have a job with an existing 5 zone multi zone unit. I am looking for a manufacturer that I can contact to request a quote. The unit is a 21000 cfm unit. Space is limited.
Can someone make a suggestion?
I have a steam powered (45psi) condensate pump. It pumps condensate return from a steam coil that is fed with 13 psi steam. Is a vent required on the spirax sarco pump that we have, and if so what size is the vent required.
We are installing 2". The coil is rated at 1300mbh.
