Author Topic: Recommended Coolant Change Interval in Projectors Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 02-12-2015 07:15 AM                     Jason: what's the part number on the carton?  |  IP: Logged Jason Raftery Film Handler Posts: 72 From: San Diego, CA, USA Registered: May 2011 posted 02-12-2015 11:26 AM                     P/N B1909086K  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 02-13-2015 02:50 PM                     I think this 33% stuff has the same part number: I haven't opened a sealed box to absolutely confirm, but we just received a large shipment and the 12 from those that I opened on site (discarded cartons before I noticed the bottle labels) are all 1/3 glycol. I have confirmed that the cartons remaining in our warehouse are B1909086K. Note that in the installation manual for 15/20C projectors, the non-operating temperature minimum is -15C. Not much safety margin.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 02-24-2015 06:46 AM                     Jason: Barco seems to be telling me the coolant has always been 2:1 water/glycol. Could you email me a pic of the 1:1 bottle label? I haven't had an MSDS come with the coolant for a long time and can't find one, as I recall it is an IBM product and the MSDS shows 50:50 concentration. Thanks, Dave The email link icon above should work for me. I tried yours but it is blocked, and the forum message thing is as well.  |  IP: Logged Rick Cohen Expert Film Handler Posts: 102 From: Amherst, New York Registered: Feb 2011 posted 02-23-2016 12:05 PM                        We are changing our coolant for the first time after four full drive-in seasons. We only put about 1,000 hours on our projectors each year, since we only operate five hours a day, and are seasonal. We plan to closely inspect the condition of the coolant once we have removed it. We have never needed to "top off" since the fill line hasn't moved in four years. Also, during the off-season, we run the projector in "refill mode" every 30 days for a full hour, to keep the coolant from settling.  |  IP: Logged Marin Zorica Jedi Master Film Handler Posts: 671 From: Biograd na Moru, Croatia Registered: May 2003 posted 02-24-2016 03:07 AM                     Rick, what projector are you using? Did you get any recomendation to do refill mode, it think it is good idea.....but doubt that anything could happend with cooling system if projector is not working?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-24-2016 08:24 AM                     Another advantage to using NEC's. They have a lifetime cooling system.... You never need to change the coolant. Where did everyone else go wrong?

But, on first they are sure it is less percent that new pump will fail after replacement, and most important, they will sell you pump with 600% more price than it is worth probably.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 02-24-2016 10:20 AM                     In fact I cannot think of another device which needs the coolant to be replaced so often. I may understand once every few years - to make sure that it's ok mainly - but every year it seems a little overkilled.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-24-2016 10:51 AM                     Of all the pumps I have had to replace its always been the Barco pumps that fail. I know Gord McLeod converted his DP-100's to have an external cooling loop. If I was serving very many of them I would no doubt do the same.

One that was on a brand new projector with just a few hour. Happened during the install. If anyone is running series 1 Barcos and has not changed the coolant it is about time. I have heard of some cases where the cooling system is getting clogged from the coolant coagulating.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-24-2016 03:27 PM                     I tend to agree that once a year is a bit excessive. I tend to just follow the Maintenance "C" time...which is 365 OPERATIONAL days...which is typically longer than a year. I've had two Series 1 pumps fail or slow down enough that they had effectively failed...both were well over the 4-year mark that Barco sets...closer to 6-7 years. The actual pump Barco uses can be had for substantially less though you'll need to source the connector and such. It is not commonly available in the USA. It is by IWAKI and is part number RD-05HCV24-12. It is an OEM part number though the overall model is a standard item for them.  |  IP: Logged Rick Cohen Expert Film Handler Posts: 102 From: Amherst, New York Registered: Feb 2011 posted 02-24-2016 11:35 PM                        I am running a four screen seasonal drive-in with all Barco DP2K-32B. Have not needed to change out any of the pumps yet. Replacing the coolant this year for the first time. I plan to carefully observe the condition of the old coolant, to determine if it could have lasted longer. The coolant replacement cost is around $50 per projector, not including the flush & fill kit which is a ridiculous $400 expense.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 02-25-2016 01:33 AM                     You can skip on the flush and fill kit. The connectors are standard that can be sourced by industrial suppliers. You don't really need the modified cap to force all of the fluid out. Just let gravity do its job.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 02-25-2016 03:34 AM                     We all agree that maybe Barco are a little overenthusiastic on coolant change but still I'd question the $50 over a potential $20.000 replacement light engine, lost shows and labour.  |  IP: Logged
