The challenge of this project, (completed October 2016) was to replace 600kW of air cooled DX plant with new water cooled chilled water plant, incl. 4 off AHUs, over a weekend. To facilitate this we built a complete skid based pre-fabricated solution off site.
The skid comprises: Dunham-Bush 600 kW VSD screw chiller
Pumps with integrated VSD
MSSB incl. BMS controls
Automatic chilled water make up system
Cooling tower chemical treatment system
Side stream filtration system
Cooling tower VSD
Maintenance power points
Water tap, flowmeters, sensors
The plant was turned off on Friday afternoon we lifted the old plant off on Saturday morning and lifted the skid on and turned back on again on Sunday afternoon at 2pm. The plant has been running faultlessly since installation.
