During this phase of the project we worked closely with the installing contractors to insure new HVAC systems were started correctly and were fully operational. Services in general included the following:
For this project, sys-tek provided their expertise on upgrading the HVAC system for the filling/capping room for their De Soto, Kansas location. From an engineering evaluation completed by sys-tek over the previous 12 months, we noted that the air handling system serving the capping and filling rooms was operating outside of its fan curve. This means that the fan was being asked to deliver more than it was designed to provide by the manufacturer.
To relieve the fan capacity, a new smaller HVAC unit dedicated to the capping room was installed. Given the requirements for the capping room were much different than that of the filling room, this HVAC split made logical sense and will provide Intervet with a system that is dedicated to system filling.
During the design process for the new air handling system, it was noted that the operators had a desire to maintain the filling room at 65F and 50% RH. Psychometrically this was not possible unless we can deliver 46F supply air. The chilled water supply for this building cannot be much lower than 42F, this supply air temperature is not possible with the equipment serving the filling room today.
In conclusion, it was decided to install a dehumidification unit to decrease the supply air dew point temperature to be 45F. As part of the design evolution, the facility operators also requested that HEPA filters be installed in the return air systems serving this area.
Given that the capping and filling room are continually in use at the facility, we will prepare phasing and coordination drawings and sequences. This will be done to insure that the uptime for the facility is as continuous as possible, knowing that there will be some interruptions. The objective will be to limit interruptions to the smallest duration possible.
