Does a fantastic job cooling, much better than any "consumer" grade unit would do. Easy to set up and very reliable. Moves a lot of air and provides a lot of cooling. Would certainly buy this again. Verified purchaser If you need to backup a AC unit that just quite can't get it done, this is it. Set it to where it only comes on if it needs to, and forget it(just check the filters regularly). Yes (4) No (0)  Report Yes (4) No (0) 1 Verified purchaser So far everything has been good. It functions as it's supposed to and has dramatically dropped the temperature in the room it's in. 1 Verified purchaser I needed a cooling solution for my studio to keep my studio recording equipment cool and at the proper temperature during the hot months here in AZ. I also needed something that would make me feel better about not introducing any dust from outside into my studio.

I found out about the TrippLite SRCOOL12K and after reading all about it believed I finally had found just what I needed to meet my needs and now that I've finally received it and installed it and my SRCOOL12K has turned out to be just that. It cools really fast and also filters the air to keep all my audio recording gear in my studio from even indoor dust and particles and I am very pleased that I made this purchase and I highly recommend it to others who have the same need and want to keep your expensive electronics cool, clean, and safe. Of course, I shut it off when I'm going to record vocals and audio with my studio microphone because everything has to be quiet, and I cool the room down real good first before I shut it off. But other than that, I run it when I writing and making my music. The SRCOOL12K is a great solution for me and my studio and I'm relieved. :) - CALEB - Verified purchaser It may be too early to write this review, because its important to see how durable and how long this nice unit lasts.

Its very easy to set up, it has a small footprint for a 1 ton unit, and it really does blow out powerful, cold air. So, thus far, i love it. It is supposed to be able to run 24x7 inside computer server rooms all day and night. I dont run it at night at all for my purposes, as im using it to just cool a peice of equipment only during the day, as we shut the equipment off all night. So, im expecting for this unit to last a long time, and it should be well built. I love that it doesnt need a water tray to be emptied, or drainage system to get rid of the condensation and evaporation. It is a self contained unit. Its a quality looking machine, so i feel comfortable putting it anywhere. Ive read almost all the reviews on this portable AC, from different sites, and it mainly got good reviews. However, the one major complaint was that when it was run 24x7, 365 days per year, it dies after about 10 months. AC compressors and units arent designed to run all day and night. So, i hope it last a long time, and is built strong enough to last several years.

In the small amount of negative reviews that i read, the company was great to deal with, and if it died within the one year warranty, they had no problem sending the customer a brand new unit. I have many other portable ac units that i use for several of my businesses that run hot equipment all day. And, in the first month, this AC seems to be the most powerful cold air portable AC that i have, compared to my other units. how to install an ac unit windowI have some other 1 ton, 3/4 ton, and 1/2 ton units, and the blower seems to be more powerful than my others, and the digital buttons are very easy to use. how much replace ac unitSo far after a month of rigorous use, it seems to be a well built, great unit.large window ac units Verified purchaser When they work, they're great.

We're now on our THIRD unit in less than 2 years, and it's refusing to work now. Our first unit died within 3 months. The replacement they sent was DOA. The replacement for the replacement lasted about 8 months. This product has done what I purchased it for: keep a small-ish room cool. I had to send in my unit to be warranty replaced about 8 months into it's life.....and the warranty replacement they sent me didn't work either....but the next replacement did work and is still working great for me. I like the slim design (doesn't take up too much room) and I like the ducting that you can use to direct the cold air where you want it to go. I also like the auto-restart feature that remembers what I had the temperature set at EVEN AFTER 7 DAYS OF OUR POWER BEING OUT!!! Not a bad unit...I would probably buy it again. A little spendy, but appears to be a bit more durable than other portable AC units. Verified purchaser It seems like we have the air conditioning go out about once a month and it usually takes two days or longer to get it working again.

This Tripp-Lite Portable Air Conditioning keeps my computer room temperature where it needs to be and saves the servers! It's easy to use and operate. I now leave it running all weekend when I am not here to monitor the temp in the computer room. I HIGHLY recommend this unit and I wish I had gotten it two years ago! Verified purchaser I have used a SRCOOL12K unit in my server room for the past 5 years. I just bought a new one and WOW! I really liked my 5 year old unit but really love the new version! Quit, efficient, easy to operate! I don't mean to geek out about it but I have over $150K worth of equipment in the room so this unit serves a very important purpose. Verified purchaser We wish we purchased this sooner.... We invested a lot of time and effort on modifying our HVAC to draw air from our server closet. This unit works very well and helps heat the office in the winter and we have the exhaust discharged outside for the summer.To a visitor who walks into a data center only once every 5 years, the computer room air conditioner (CRAC) units that line the perimeter may look remarkably the same as they did 5 or even 10 years ago. 

It’s like an imaginary alien who comes to visit earth in 1957 and sees a Mercedes-Benz automobile. When he comes back in 2017, he still sees metal vehicles with four rubber tires, a hood, a trunk, doors, seats and a steering wheel.  He might come to the conclusion that nothing much has changed. However, as all car owners know, what is hidden underneath the hood is what makes the car so different in terms of performance.  The same holds true for the new CRAC units.  For data center owners, the technology changes inside the box radically alter data center energy costs and how that data center operates. A case in point is the new Schneider Electric’s family of Uniflair LE 50Hz CW (chilled water) CRAC units. As data centers consolidate and continue their rapid migration to collocation and cloud facilities, the demand for such chilled water units continues to grow. At one Schneider Electric colocation customer, the cooling experts onsite had the luxury of accessing two CRAC units of different vintages side by side.  

One was 15 years old and the other was a brand new Uniflair LE unit. Both were operated under similar conditions and were tasked with the same workload. Although roughly the same physical size, the new Uniflair LE unit consumed 50% less power at the same capacity.  Studies have shown that in data centers, 41% of the energy coming in feeds the cooling systems.[1]  Therefore, adding high efficiency cooling units to the data center means that significant operational savings will result. Why is there such a stark performance contrast between the old and new units?  The answer lies “under the hood”: New materials that streamline the fan design – The fan technology inside the box has moved on from metal blades to a moldable composite based design. More flexibility in molding the blades allows for engineers to design around a more aerodynamically efficient shape. Such designs are now crafted in 3D as opposed to the old 2D.  This alone added 20% in efficiency and results in lower power consumption and less noise.

New motors – The old asynchronous motors (motors with brushes) have been removed and been replaced by electronically commutated motors integrated with an impeller (brushless motors). Such a change avoids the friction of brushes and allows the motor to run more efficiently. In addition, these motors are controlled by variable speed drives (as opposed to fixed speed drives) which means that motors only spin at the speed needed to accomplish the task at hand. New ability to handle a broader range of data center temperatures – Increases in the ASHRAE recommended data center operation temperature ranges present technological challenges for older CRAC units. The “chilled” water that the units traditionally utilize has now turned “lukewarm” and with larger temperature differentials; this impacts how the thermodynamics are managed. To accommodate this wider temperature range, the coils inside the box are optimized differently than before. The recommended operating conditions also modify how humidity control should be managed (humidification targets are no longer based on relative humidity but on actual moisture content in the air).

A system that facilitates high efficiencies for system-wide cooling, beyond just the CRAC – The Green Grid survey of data center operators showed that use of economizers will result in saving an average of 20% of the money, energy, and carbon for cooling when compared to data center designs without economizers.[2] The new CRAC units utilize an Optimized Management Interface (OMI) that is designed to maximize chiller/economizer efficiencies by responding to the cooling load in real time. Data center professionals can leverage best practices related to cooling that supports an increase of operational efficiency, sustainability and reduce energy consumption by up to 20-30%.
