E3, Pack Controller, I Pro, O my Brett Looks Like He’s From Arkansas!! Episode 527

Post-Anesthesia Tech Tips: iPRO V5 ADF File Failures, Valve Driver Mix-Ups & Danfoss Tunneling Gotchas

Brett and Kevin kick off the Advanced Refrigeration Podcast with Brett fresh out of oral surgery and sounding “absolutely hammered,” then pivot into startup tips for new CO₂ racks using E3/E2 controllers with iPROs. They warn that many OEM programs load the wrong ADF files—using iPRO CO2 instead of the iPRO V5 ADF—causing pressures/temps to read correctly while the HPV stays at 0% and won’t open, potentially high-heading and shutting the rack down; the fix involves deleting old ADF files and fully reprogramming the application. They also cover common configuration mistakes like valve steps being “x10,” assigning valves to the wrong drivers on V5 dual-driver setups, verifying peak/holding current and step rates for Danfoss valves, checking swapped T1/T2 sensors, and adding backup network P/T sensors for redundancy. Finally, they describe Danfoss PAC/System Manager tunneling being disabled after about eight hours for security, a Danfoss controller IP-address glitch that may require toggling HTTPS/DHCP or reloading the program, and the importance of correct HTTP vs HTTPS ports when connecting remotely.

Target Startup Chaos, Buggy CoreLinks, andDanfoss EKE400/ICAD Headaches | Advanced Refrigeration Podcast

Brett and Kevin open the AdvancedRefrigeration Podcast after a brutal week, with Brett stuck on a transcritical Kevinwith a  startup at a poorly designed downtown store wherethe E3 and roof access are far from the grocery and the rack is on the roof. Heblames electricians for mis-marked and mixed-up comm lines, missingcontrol-power splices, and dangerous live voltages, turning a “simple” startupinto days of rework. They also vent about painfully slow, buggy CoreLinksetup and web UI issues compared to smoother E3 terminal mode. Kevin then walksthrough using a Danfoss EKE400 in CoolConfig for defrost and reheat control, MMRGdisplay jumper/address quirks, Modbus connection ideas, and generating wiringdiagrams. They finish with ICAD failures, O-ring moisture/rust problems, andsolving calibration alarms via process-of-elimination part swapping.

Skills Canada Gold, Rack Life inNewfoundland, and the Great Apprenticeship Debate |

Advanced Refrigeration Podcast In this episode of the Advanced Refrigeration Podcast, hosts Brett Wetzel and Kevin Compass welcome Devon Owens from Newfoundland, a three-time Skills Canada gold medalist, to talk shop andtrade some laughs. Devon breaks down Skills Canada—provincials, nationals, and worlds—plus the intense 15-hour two-day refrigeration build he finished as theonly competitor, featuring a two-evaporator, two-temperature system with EPRs, solenoids, transducers, a superheat controller, and an EEV. The conversationshifts to how Canadian apprenticeship schooling differs from U.S. union training, including unpaid full-time pre- eployment, block exams, pay-scale progression, and a challenging 125-question journeyman exam that spans everything from CO2 and ammonia to natural gas. They also touch on rack work,CO2 sites in Newfoundland, 600V power, and why water leaks can ruin your day.

Parallel Compression, Oil System Differences & Brett's Flat in Bat Country - Episode-524

Hotel Wi‑Fi, Flat Tires & Parallel Compression Chaos | Advanced Refrigeration Podcast

Brett Wetzel and Kevin Dumpless kick off this episode from a wildly bright SpringHill Suites in Fort Worth after travel chaos, traffic frustration, and a flat tire that dropped pressure to zero in record time. From there, they jump into real-world rack work: long weeks on a rack change-out, frustrations with manufacturers leaving no room for core pullers on EPRs/A8 valves, and the familiar pain of electrical contractors who don’t read prints. Kevin walks through a parallel compression CO₂ startup, including staging issues tied to flash gas bypass valve capacity, oil reservoir differential problems, and how a weighted check valve maintains oil flow when flash tank pressures rise. They compare oil separator strategies, discuss ICAD reliability versus steppers, and highlight a dock reheat/dehumidification setup using defrost return gas and controls.

Newfoundland Time, 43-Year-Old Hill Racks, and CO2 Mini Packs Gone Wild | Advanced Refrigeration Podcast

Brett and Kevin open the Advanced Refrigeration Podcast with travel chaos and stories from Brett’s Newfoundland training trip, including sightseeing, getting “screeched in,” and learning about the 2 and a half-hour time zone. Kevin contrasts with a rough week changing out 43-year-old Hill racks for new Hussmann racks, dealing with tight valve layouts, vacuum work, reused refrigerant, and major electrical/control complications in an old store with fuse buckets. They explain what Atron surge receivers are, why they fail, and common retrofit approaches. The conversation shifts to small Walmart CO2 “baby” racks and common field issues: critical charging challenges with heavy tanks, relief valves popping due to 650-psi-rated filter driers, problematic relief piping requirements, and the need for better high-pressure serviceable solutions. They close by teasing a deeper future episode on these single CO2 units and their controllers.
