Propeller Breeze Users

[qnguyen]

Hi,

For those of you using the Propeller Breeze, do you find that it moves a lot of air? I have the Propeller Breeze III 3 fan and it provides a gentle breeze but I was expecting more. Is this normal? I am using mine with the PropellerController. I am observing the fan speed when my tank temperature is at 79.5F, which should be triggering the maximum fan speed per my 1-10V settings. The draw is 0.05 amps if that helps. I want to keep my temperature no higher than 79F to 79.5F, but my temperature is drifting above 79.5F. So either I need a more powerful Breeze (4-fan) or the 3-fan I have is not working the way it should. FWIW, I have a 90 gallon tank with a basement sump; pair of 250w metal halide lights and ambient room temperature of 75 degrees.

Thanks

The breeze fans are weak. I have a 4 fan unit and it only does a marginal job. I bought a cheap $20. Vornado desk fan and it keeps the tank cooler by it’s self. The breeze doesn't even come on when the vornado is running.

Thanks. I may need to do the same. I am already hitting above 80 to 81F with daily temperature swings of 3 degrees and it is not even the height of Summer yet. I like my Giesemann Spectra but it definitely generates too much heat.

Not really an apples-to-apples comparison.

We're talking about a single large fan vs. multiple small fans. Of course the single large fan will push more air due to the size alone. Can you mount the vornado to the side of the tank like a breeze fan? How does that look? Can the speeds be controlled by the ProfiLux? What about the overall bulkiness of the fan? Not everyone has the space for these and would rather have something that has some cooling capacity while matching the overall aesthetics of their system when it's mounted to the display tank.

Let's not forget about the other variables which play a massive role in the effectiveness of a fan. It's not just about the size of the fan. Effectiveness will vary based on average ambient temperature, current humidity levels in the room, lighting type and duration per day, pump type, pump count, UV in-use, etc.

I'm glad you were able to find something more suitable for your specific application, but let's not throw around blanket statements without acknowledging that user results will vary for the reasons above.

@qnguyen
The cooling difference feature should only be used if you want to delay the cooling reaction.
Page 58 of the P4 programming guide has more info on this.

If this is not the case, then you can set it back to 0.

The switching ON point for the cooling function is determined by this equation:
T = nominal temperature + 5/6 * hysteresis + cooling difference
(Page 46)

With your current settings and cooling difference, the fans will turn ON at around 79.2°F
With your 1-10v at max settings, the fans will run at max speed when the temperature is at or exceeds 78.9

This is causing a conflict because you are telling you want the fans to run at full speed at 78.9 yet there is a cooling delay at 79.2. Either remove the cooling reaction or edit the 1-10v max at deviation setting.

I use the propeller breeze. 4 fan. Does it work it works does it cool my tank down. I dunno I have it then on and my tank has never got 78@* and I live.in hot ca. Where it gets 103 or 107 in July. Well see. But once I get the t5 hybrid for my LX7 I'll probably get more than 4 fan maybe. 6 fan.

Thanks Vinny. That is very helpful. I removed the cooling reaction.I think that will make a big difference.

We are talking about a single 4" desk fan that is out performing a 4 fan unit with 4" fans in it. It's mounted to a cabinet next to the tank. It doesn't look bad at all and it's hardly bulky in any way. It's easily controlled by the P4 powerbar. It has three speeds. Yes, it needs to be manually adjusted for speed.
But do the math. $20 vs $169.80 ($129 Fan unit + $39.90 Controller)

Yea, lets not throw around blanket statements. But from MY experiences this $20 fan does a far better job of cooling than the breeze unit I own. If I did it all over again, the GHL fan would never have been purchased.

Looking at everything the GHL looks bulky in comparison.

I couldn’t find the CFM specifications for that particular Vornado model, but the Pivot3 (which is the next model up) has a max setting of 140 CFM. I think this would be a good science fair project for a high school kid to do. Compare the evaporative efficiency of one fan with 140 CFM versus four fans with combined 140 CFM (or 141.3 CFM in the case of the Breeze 4-fan). So ... does anyone have a bored high school student that would be willing to run this experiment??

GHL Specifications:
2-fan: 120,000 l/h (70.6 CFM)
3-fan: 180,000 l/h (105.9 CFM)
4-fan: 240,000 l/h (141.3 CFM)
5-fan: 300,000 l/h (176.6 CFM)
6-fan: 360,000 l/h (211.9 CFM)

@AZMSGT u still have it laying around?

@AZMSGT u still have it laying around?

Yea, it’s literally laying on the floor between the tank and the control cabinet. When I had to swap out tanks I haven’t taken the time to set it back up. My previous tank failed in early Nov 2020 and I won’t need any cooling till April. I’ll still use the breeze in case it’s needed and have it set up. It’s my back up to the other fan.

If you ever don't need it. U know where to find me. Trying to get a new mount for mine. Since one snapped

Here’s the terrible part, when I got my Breeze the first thing I had to do was reverse the mounts so the screw heads where on the outside. When I took them apart I saw that the people at the factory had way overtightened the screws and the plastic was stress cracked. The brilliant minds at GHL told me not to worry about it and it shouldn’t be a problem.. I asked for replacement mounts that were not damaged. They told me they couldn’t get them. What a load of baloney.

Interesting. @Vinny@GHLUSA vinny asked germany for replacement bracket. Atleast one. I'm hoping two since other is bent.

I now discovered that if u loosen the screen at joint to be able to bend the fans in my direction way easier. Then tighten it. I thought it was just tough to bend in different position I think that was issue with pressure on plastic clamps. But I have yet to hear what germany told vinny. But yes. I turned mine around to so screws are in the back.

I only had it for this summer. Not even a year lol. If it's hard to get brackets I asked if he can talk to ghl about a credit or something for a.new unit. Because if that's the case I'll just buy the 6 fan unit

My 5 fan GHL unit just stopped working.

Anybody encountered that before? Any specific I should be checking?

Open a support ticket so we can troubleshoot it.

Done and done. Thank you.

Done and done. Thank you.

When you have it working maybe you can leave a post to let us know what the issue was…

 

[DeputyDog95]

Well, so far I have followed the trouble shooting steps that were supplied to be my support.

I emailed them a pic of the unit and where it's mounted.
I verified the outlet supplying the fan is getting power.
I sprayed canned air into all the fans and they spin freely.

The only thing I don't know how to do test the unit with a multi meter. I have a MM, but don't have the first clue on how or what to measure on the fan unit. I asked for clarification and they haven't responded yet.

I did realize how much of an impact the 5 fan unit had on the tank.
Not only is my tank 2 degrees hotter, I have so little evaporation now I can't dose Kalk anymore without rising sump levels, which has dropped my pH significantly. Kind of a chain reaction going on there.

Thank you for update…
Did you reply through e-mail or the web interface?

It you replied to the email they will not respond,
One needs to go to the web portal and provide response. That got me few times .
