I guess you may not be familiar with water cooled air handlers, take a look at hydro innovations... Insulated res, inline pump, chiller, opticlimate, done.
Using water to cool your room is way more efficient then using A/C...
this opticlimate thing does not have a water cooled evaporator.
it has a water cooled condensing unit. it operates much the same as a conventional package AC system, except that the heat is rejected to water not air.
i think you are misunderstanding what this thing does.
chillers do tend to be more efficient than conventional forced air units, but not terribly so.

No i'm very familiar with them as I have a buddy of mine who only runs water cooled rooms instead of A/C's and he has several Opticlimates set up on a recir system on chillers.
He has stainless steel insulated res's...and they are way more efficient because the chiller doesn't have to run the entire time that Cooling is needed because the water in the res stays cold, and when the water warms up to a certain point the chiller kicks on...It cycles way less then my 5 Ton A/C units...
Gavita pioneered the high frequency DE ballast. They have been through several generations of this equipment. I bought Gavita because that was what was available locally. It is a solid, well-engineered ballast and my only complaint is that the dimming knob looks like it came off a '70s stereo system. That's Europe for ya.
Gavita says that their ballasts don't run hot. When they are wired to >200VAC inputs - as is all of Western Europe - I am sure that is true. However, on US 120VAC, the Digistar runs very hot - surface temps of 135F-140F. That is to be expected due to the step-up voltage transformation that is going on in conjunction with the HF function. Either wire for 240VAC service or set about a 20w fan on top of the ballast for cooling.
Maybe it would survive without the fan, but I feel the electronic components will last significantly longer with the fan cooling. I got one from Radio Shack and plug it into the same timer that is used by the ballast.

Solis tek ballast with remote and built in timer have been a blast. Their se bulbs the absolute worst I ever lit. 3 out of 4 1000w hps didn't last 48hrs. 1000w mh strobes pink and blue. In your hand they are feather light, feel as tho solis put more money into packaging than bulb strength
Yeh so many dope growers lack scientific equipment in their cellars. It's an outrage that we settle for the anecdotal
thats retarded.
hes using a chiller to cool the condensor on an air conditioner? do i understand you correctly?

I've been using Solis-tek 10k single ended bulbs to supplement Hortilux bulbs during the last two weeks of flowering. I like the results and have not suffered any bulb failures. I intend to supplement Gavita doubles with Solis-tek 10k doubles the same way.
No...He is using the chiller to cool the air handler (opticlimate) just like hydro innovations does.
sorry... humor me here.
hes using a chiller to cool a closed loop of water correct?
this chilled loop is being fed into the opticlimate correct?
is this chiller air cooled? if so... presumably this air cooled chiller is outside the room in question here?
ok this is retarded with respect to efficiency... and ill tell you why.
this is called a cascade refrigeration cycle.
basically the cold side of your chiller is cooling the hot side of your opticlimate, making the opticlimate perform very well.
i wish i could send you section in my book about this subject, but fuck if i know how...
basically you have 2 compressors, 2 sets of plumbing, 2 motors pushing air, 2 evap and condensor heat exchangers(though the junction of the two systems often shares one heat exchanger) ... it goes on and on.
generally speaking cascade systems are going to be around half as efficient as a single refrigeration system at cooling to regular temperatures...
your friend probably made this modification to address performance issues with his opticlimate? cooling the condenser thusly WOULD increase the cooling capacity of the opticlimate... but at the expense of wasting more energy than say... just adding another opticlimate unit.
why then do folks use cascade refrigeration systems? because cascade refrigeration systems can produce fantastically cold temperatures... all the way down to co2 refrigerant.
you may not think so, but your conventional air conditioners are going to be more efficient at removing heat....
No you are not understanding it at all...I encourage you to look up water cooled airhandlers as it will make it easier to understand.
Check out hydro innovations and it will be crystal clear how this system works.
1 condensor (chiller outside of the grow room), an inlet and a return for plumbing (1 set), 1 motor pushing air in the airhandler...
He has a 5 ton banks water chiller, an insulated res, and a 1hp pump that recirc on a closed loop to the airhandler. Cold water enters the airhandler, goes though the coils, the airhandler has a fan that blows over the coils and into the room, the return water is much warmer, and that warm water enters the res where its cooled.
well, i understand chillers very well,i do have section 608 card and some self teaching to speak of.
i am familiar with the hydro logic people... they basically just re brand goodman condensing units and slap plate heat exchangers and a pump into them.
i think where im loosing you is when you mention a chilller unit AND the opticlimate unit.
does the opticlimate company build fan coils as well? because as far as i can tell they ONLY make these water cooled air conditioners...
is he somehow... not utilizing the refrigerant system within the opticlimate? if so why?
are you sure your friend isnt just using some standard fan coil? they are way cheap... and can be ducted just like this opticlimate thing.
The opticlimate is just a water cooled airhandler, it is NOT an air conditioner...there isn't any refrigerant in the unit...
no its a water cooled air conditioner.
i just looked again to make sure. perhaps you are referring to a product that is no longer sold? im looking at their website right now.
they also make a split non water cooled unit.

been looking myself , is this the one? OPTICLIMATE PRO 3 CLIMATE CONTROLLERS WATER COOLED AIR CONDITIONER.
I can assure you that there is no condenser of any kind that comes with the opticlimate nor is there any refrigerate in the unit...Instead of freon it uses cold water to pass though the copper coils.Check out the manual. Its an airhandler that goes in the room and is hooked up to a cold water line inlet...They may call it an air conditioner, but it is not exactly that....They are designed to run on a DTW set up but at a cost of 5 L plus per minute...Hence why my buddy runs them on a closed loop set up.
Like I said I've seen them in action personally...
Cheers

there's a member in the ozy section running one.

its a water cooled air conditioner.
can we put this to bed yet?
Funny how this thread started as a comparison btw 2 DE bulb mnfgrs to talking about fucking air handlers, jumped the shark. Does anyone else think it's odd that philips is no longer producing the DE bulb since they are the company (with Gavita) that got the whole thing started in the first place .
