Original Aqua-Air CAD drawings for the AQ900HD Chiller
Aqua-Air has project records dating back to the early 1980's detailing the equipment that we have supplied for all of our large projects. One of the requirements of this project was for the chiller to fit in the same exact position and connect up to the existing chillwater piping. With our extensive CAD drawings for this project it was very easy to be assured this unit would fit exactly!

The unit is also equipped with a highly innovative Manual Bypass System for the PLC which allows the crew to still control the chiller in the unlikely event that there is a catastrophic failure of the touchscreen or PLC. A copy of the chiller specification is shown below.
