Phase Change Assembly Line Produces Twin 1

11.11.07 - 07:59am

Friday saw the culmination of a few weeks of effort with the shipping of Twin 1 from my current line of single-stage builds. Over the last few months I’ve been honing down this build process to a standard assembly line and I do believe I have finally sourced all the components. These particular builds, Twin 1 and Twin 2, do feature a few new things to my ensemble of builds. Most notably is the switch over to under-the-ice.com’s IceBox single-stage case and Christos’ Freeze Pack controller. While the cases fit seamlessly into my design, the controller was a slight issue as I didn’t realize it required an additional 12v powersupply to power the board which in the end added a slight delay. Been a pleasure assembling these units though, some of my finest I must say but I always see room for improvement.

Stats

At their core these builds are my standard bread and butter builds, not much variety here as consistency in quality and performance have been my ultimate goals. These units are part of my quad-core tuned line and are capable of holding 275w comfortably and will scale up to 350w albeit with positive evaporator and core temperatures. Here’s what went into these builds, not everything is listed due to the sheer number of little bits and bobs.

• Compressor: Danfoss NF11FX
• Condenser: Chilly1 Little Blue
• Suction: 16″ of flexible stainless steel
• Evaporator: Chilly1 2007 Spiral Evaporator with mount
• Controller: Freeze Pack with MeanWell 12v PSU
• Case: U-T-I.com IceBox with Freeze Pack LCD mounting
• Charge: R507

Performance

These particular builds, being of the quad-core tuned NF style, won’t be hitting crazy low temperatures at idle but they’ll hold loads that would make an Asetek VapoLS breakdown and cry. Under 275w load the system was holding stable at -16C on the evaporator face, -9C on the loadtester core, and a modest 9PSI suction and 265PSI discharge. Somewhere I have a photo of the unit idling around -40C but this isn’t safe in the slightest as the heavy charge causes near-immediate floodback when dropping from a load to 0w load. The minimum load necessary to prevent any floodback was 105w but if this unit is under a quad I can’t imagine it being loaded with anything less than 200w. Noise was rather low although the 110v condenser fan is still a bit loud and drowns out the soothing compressor hum. At 275w load the unit was pulling 402w from the wall, this included the condenser and exhaust fans, the controller, and the compressor.

Here’s the final photoshoot, if you want pictures of the build process let me know but be warned, they are a bit messy. Giving birth to one of these is not easy process.

This is what I build in, haven’t washed those jeans in weeks.

Conclusion

Another CryoFX production that turned out perfect. Hope you enjoyed the show, will have another identical unit finished today and then a Lian Li V2000B Single Stage tonight.
