The cost of replacing the reflector alone (if its being replaced at all) is more than replacing the fan motor.

I bet I know who you're working for.

Understand the exhaust fan and lamphouse blowers are two different things. The exhaust fan is external to the console, usually mounted on the roof, and draws the heat away from the equipment. The lamphouse blower(s) keep air flowing over and around the bulb.

Depending on what flavor of Christie console you have: Dayton 4C446 blower (or whatever number the maintenance-free replacement is for that now, I can't remember)= about $50 from Graingers.

It installs like it looks, four screws, two wires... simple.

Century has always taken the position that water cooled machines must have water AT ANY POWER LEVEL of bulb. You have options (1) convert to an air cooled gate (2) purchase a water circulator.

I assume you are 2000 watts or lower so air cooled is OK. 3000 watt up needs water.

Most building codes REQUIRE proper blowers and exhaust. It is the minimum the owner owes you: proper working conditions. Louis

I can understand the situation from owner's perspective. Those Century's use a lot of water and he doesn't want to be responsible for a water shortage, and surely he is just trying to save our wonderful planet. By not repairing the blower fans he is going green... green with a few extra dollars he is saving. What a great guy! I bet he has many friends and I'm sure lots of people admire this clearly wonderful individual.

Derrick, your owner is a cheap assfuck. I bet he is ugly and I am 100% confident he smells like unwiped anus. You can quote me on that. Print this out and show him. His wrath is not something I fear. He seems weak. I also bet he has a really small dick on the underside of an inch.

A water cooled gate doesn't have to be connected to the mains (in fact it is better off not done that way but with distilled water and a circulator)
If one is on a tight budget (frugal cheapskate) then get a garbage pail and a lawn fountain pump and connect that up

"Cheapskate" and "uber stupid" just don't do this guy justice. We pay about $3.25 for 1000 gallons of water here. At that price ten gallons of water in a closed circulating system would cost the owner 3.5 CENTS!! Could it be he doesn't drive his car because it wears out his tires and mileage on the speedometer reduces the Blue Book value?

'Nother thing about those pesky fans. They exhaust the ozone created by the lamp. Health effects of ozone Fans are much cheaper than negligence lawsuits, both to fight and pay off.

We can't blame this guy... he knows this is wrong... but we can blame his boss! If thats the 4000 watt Christie SLC40 console you've got there NOT runing the exhaust blower will bake the coating off the mirror... if that already hasn't happened. It will also happen if you're runnign a 3kw lamp but it'll take a little longer. A new reflector for that lamphouse costs nearly $2,000.00, the lamp warranty will also be void as the manufacturer can tell from exammining it what temperature the lamp was operating at. You don't hook your water cooling jacket on the projector to the main water line you use a water circulator. Not hooking a Century water jacket to something with cooling fluid going through it can eventually cause the dovetail in the projector to warp... its made of copper...very soft! Coolant should be distilled water and at least some ethelene glycol mixed in... anout 20% in your area should work good. Don't use the cheap anti-fereeze from Wal-MArt either... it'll grow fungus at a fast rate and plug up the coolant lines! I just rebuilt an SLC40 console last week that came in from Portland, OR. for an upcomming plex install we have next month... its mirror coating was baked off... also replaced the airflow switch in the stack and all the cable ties with black IR and UV resistant ones . Heat and dichroic mirrors don't mix along very well. At least 1200cfm exhaust for a 2kw, and 1500cfm or more for a larger lamp is adaquate. Tell your boss that we all think he's an iddiot .

Re: Your wanted ad for Ultimations... This is still being currently produced by EPRAD so good luck gettingn one cheap... it is one of the best of the computerized automations though. Much better than the CNA versions they build for Strong.

P.S. Tim, You can't use that dayton blower in the SLC series consoles... it requires a 3600rpm plenum blower which is only available from Christie. Its the 3600 rpm blower thats part of the secret to long lamp life in these consoles... no one else I know of uses a blower moving that much air. The nice thing about the current blower from Christie is that the motor is ball bearing! No more crappy Dayton motors to replace...

Ummm, I think when I said, "depending on what flavor of Christie console you have" sort of encompassed that. I know all about the upgrade kit for the SLC plenum blower. Besides, there are additional blowers in some SLCs that ARE 4C446's.

I wish the hell you would stop trying to qualify everything I say.

Some of the Dayton blowers have converted from sleeve to ball bearing while keeping the original "4C" number....since they are being sourced to China, they can now afford ball bearings Still prefer EBM-Papst

We've had pretty good luck with FASCO but their replacement line is alot mroe limited than Daytos is.

Re: SLC or not..As far as the mirror goes the make and model are irrelevant. Dicro or not the reflector can still burn.

We're using Elicent AXC 200B on both of our film machines and the Barco DP100 along with a roof blower. They are very quiet and move more than 650 CFM each. All ball bearing motors and all steel construction. For us they have been well worth the price.

Thank you all for your reply's. I think i am going to make a short video of all the poor working conditions that i have at my theater. If anything it will be amusing to watch, and perhaps if there are certain conditions that are fire hazards, or safety issues you guys could point out, so perhaps i can anonymously report him to the proper authority. That seems to be the only way anything will get fixed. If he has no other choice.Any suggestions where would be a good place to upload the video? (you tube, meta, etc)Well thanks guys. Be sure to look for my new movie project: "How NOT to run a theater" Coming soon

It's not so anonymous, though, when you openly discuss it on a website.

And methinks if your boss finds out about this he's gonna let you go pretty quick. So be careful.

Good point. I doubt he reads these forums, but someone here may know him. Oh BTW Chris, about replacing bulbs. its not that i personally want to wait until the screen is black, problem is, we are not authorized to change bulbs without owners consent. hell even if we wanted to its not like we have any spares there.your talkin about a guy, who has his projectionist manager running scope films with the curtains still set to flat, so the film shows on the side. and he is my superior. simply because he doesnt want to bother to reprogram the automation. ( he might not even know how to do it)

Dang, with horrible working conditions like that,sounds like you need to scoot to another theatre or occupation - for you know that you aint gonna change things the way you think or know how they should be.

Sad thing, is that these kind of people are 'dead right in themselves' and even though you have great motives in making things better, this will surely offend him in the way that possibly 'someone is showing him up that things can be run better'..even though he knows he's wrong in operational procedures but either 1)-not admit it (which is the usual first case), or 2)-this is how he's gonna do his business and nobody is going to alter it in any means or form.

Bottom line: he's prob the guy who doesn't want any sort of competition within his business. For if you show any form of competition, he'll give you two choices - either live within his operational pattern, or hit the road onto something else.

I call it "the Pyramid Operation" since one person only is allowed at the top and the ones below him, on both legs, do his bidding. You might say, people below him are working for him to fulfill his dreams. (Rather horrible working conditions, if you ask me ...)

Trust me: been there and done that in this industry and still came up short in trying. Thus, esp in your situation, either live with it, or bail to something better.

Good luck - Monte

In 26 years I've found the biggest battle with owners (and contractors on new construction) is getting them to install an exhaust system for the machines that meets specs.

The owners and contractors bitch about the cost, the HVAC engineers want a freaking BTU and Calorie per hour (yes one HVAC contractor actually asked me for that spec) that the lamp puts out.

I've found that the only way to get what's needed at the stack is to ask for +150% of what you want, then you'll get what you need.

Current bid I'm doing now, I want 450cfm per machine, so I asked for 600. So I should end up with the 450cfm I really need.

Oh, and for land's sake don't mention the "O" word. Especially on a government job. That'll trigger a whole slew of data requests and environmental impact reports. (For those who don't get it, the word is Ozone.)(And of course, virtually all modern xenon bulbs are ozone free.)

Posted by Frank Angel (Member # 248) on 05-02-2008, 02:27 AM:
 
Well, actually they are now ozone free-ish. They still put out ozone but not in the amounts that they did before the manufacturers realized they would have projectionisists coming down with all kinds of bronchial ailments if they didn't do something about it. Actually, even when they did give out lots more -- I think I heard long ago that the first bulbs gassed out more than 15 times what they do now -- if you exhaused them properly and I guess if you weren't so stupid as to stand next to the lamphouse all day with your nose pressed against the snout, taking in deep breaths, it wouldn't do you any harm. I mean if you could survive years in a carbon arc booth with the toxic soup THAT stuff belched out, you certainly could survive that nice fresh smelling ozone.

I never could figure out what the big deal was anyway....just pump the ozone out the stack and it will plug up the supposedly big hole in the ozone they were always whining about. Either you're depleating the ozone with spray deodorant or you're making to much with your xenon bulbs and the Ionic Breeze. You can't win with these people.

I'm astounded that you couldn't get it. Something needed many miles up in the atmosphere isn't something that's necessarily good to have in large levels here at ground level.

Smog is often caused by ozone at low heights
The engineer is correct to ask for BTU amounts as sizing of the booth HVAC needs that information as is the amount of exhaust as otherwise there will not be enough makeup air and the booth will be at a massive negative pressure

Although I'm sure Frank is loaded with Vitamin C (definition of ascorbic"), I'm sure he means "acerbic" (acid in temper, mood, or tone), which fits me as well sometimes.

As far as the non-blow-hards we've been discussing, would any try to run a vehicle without a fan or fanbelt? It's the same freakin' thing.

Remember, guys, that ozone is inherently unstable. If you store it for awhile in a crawl space, for example, O3 becomes O2 (oxygen.) Louis

Louis is even more right then he knows, ozone will rapidly decompose into O2 very fast. concentrating it is a bad idea, but the removal of the ozone to the outside is a good idea.

What I want to know is 280 CFM enough airflow for my Kneisley lamp house?
what I use is this in-line unit: nutone
I have two of them but only one hooked up, so what if I staked two of them one right after the other? Or installed a Y and had one on each end. would that help to ventilate out.
