Condensate blows pass drip pan
(OP)
I have 100% OSA HVAC's(chilled water) which doing temps above 66 degF and high humidity the unit leaks below into production areas. The first attempt was to install a 35 deg angle catch pan and caulk after install but, we are still having issue. Any suggestions and is there a coating which can be applied on the floor of the HVAC to help stop the issues?

Next thought would be velocity as MechEngNCPE mentioned.

If any of this is interpreted correctly, keep cooler discharge air temperatures.

Another option to decrease cfm and therefore velocity over the coil is to reduce supply air temp. He may want to try to change the supply air discharge setpoitn to 52 degrees or so. Also, 6 years is a long time for a balance, especially in this industrial setting. Get a TAB report done asap.
The other issue could be with the condensate drain p-trap not being deep enough for the negative static pressure of the fan. If the difference in trap height is less than the inches of static after the coil, then it is not deep enough and condensate will get sucked out, causing leakage.
