have a trane RTA Chiller - twin screw. CKT 1 is tripping on low evap temp.
CKT 2 runs all day but is only pumping out 50 deg water - by the time it is reaching the secondary it is 58 deg. Could this be a plugged strainer on the primary if so why is the secondary so warm and why is this thing running if it is plugged. thanks guys
