Issue:
Can I weld the water piping to the waterbox connections of the chiller?
Resolution:
No...Pueblo built water chillers have water boxes that are made of grey cast iron. Welding the water piping will affect the integrity of the metal and can cause micro fractures causing the heads to leak.
The CGAM chiller uses a braze plate heat exchanger and does not have waterboxes.
Notes:
There is one exception to the above. The optional marine water boxes on RTHD condensers are made of steel. Welding would be permitted if required in this application.
