Author Topic: Looking for information about cleaning IMAX Water Cooling systems Dan Reiter Film Handler Posts: 74 From: Easton PA Registered: Jul 2002 posted 09-01-2009 12:25 PM                     While we sell the 12 & 15 K lamps, we do get the occasional question about cooling system care. Is there a good source, document, or site that has some good info, especially for cleaning out algea and sediment? Thanks!  |  IP: Logged Bob Brown Expert Film Handler Posts: 146 From: Grand Rapids, MI Registered: Apr 2002 posted 09-01-2009 02:19 PM                        Dan, I would contact IMAX and ask for Vic Benson. He is the guy for GT systems. He sure would have your answers....  |  IP: Logged Adam Martin I'm not even gonna point out the irony.

Note: Reverse steps 1 & 2 if you haven't showered in a couple of days. 3. Vacuum algae and sediment from floor.  |  IP: Logged Dan Reiter Film Handler Posts: 74 From: Easton PA Registered: Jul 2002 posted 09-03-2009 11:01 AM                     What agent, chemical, or cleaner have you used when flushing the system? I guess that is a good place to start, and a big piece of the answer.  |  IP: Logged Adam Martin I'm not even gonna point out the irony.

The CCU has several filters which get changed regularly and should eliminate any sediment in the cooling system. A roof-mounted chiller may also have an antifreeze added.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 09-04-2009 08:10 AM                     I only drained ours a couple of times but never flushed it out  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 02-06-2011 09:15 AM                 It has been 520 days since the last post.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 02-06-2011 09:15 AM                     The lamphouse circuit should never need cleaning. The chiller/city water loop can be cleaned by whatever procedure a HVAC contractor would clean a chiller loop. I've seen them add some chemical to the chiller water, run it for a while, then flush it really well. I don't know how you might clean a city water loop. Or if you ever need to.  |  IP: Logged Jake Spell Master Film Handler Posts: 294 From: Johns Island SC Registered: May 2009 posted 02-07-2011 12:34 AM                     City water can contain minerals and leave behind scale and other deposits lowering the efficiency of the heat exchangers. If it ever gets to this point then a de-scaling solution can be added and circulated but I dont advise this as it WILL eat away the metal in the system, so unless you have tried every other solution and are still getting temps that are too high, dont use a de-scaler.  |  IP: Logged Dick Vaughan Phenomenal Film Handler Posts: 1032 From: Bradford, West Yorkshire, UK Registered: Jul 2000 posted 02-07-2011 07:10 AM                        Hopefully you shouldn't be running on city water long enough to allow mineral scale building up, it's only there as a backup for when the chilled water system is down.  |  IP: Logged
