# Natural-Refrigerant Condensing Units Hillphoenix Adds Advansor FlexONE for Tight-Space Retrofits By Adam Harrie | Written with AI assistance | Published 2026-10-16 | Business Source: Trend Hunter, https://www.trendhunter.com/trends/natural-refrigerant-condensing-units References: [prnewswire](https://www.prnewswire.com/news-releases/hillphoenix-unveils-advansor-flexone-co-condensing-unit-for-food-retail-and-industrial-markets-302908749.html) & [hillphoenix](https://www.hillphoenix.com/company/hillphoenix-at-a-glance/)  Hillphoenix is expanding its natural-refrigerant hardware portfolio with Advansor FlexONE, a [compact CO2 condensing unit](https://www.trendhunter.com/trends/thermal-management) built for refrigeration projects that require flexibility in tight spaces and for retrofit work. It is designed to help [food retail and industrial sites](https://www.trendhunter.com/trends/single-glass-door-freezers) modernize cooling without relying on synthetic refrigerants. The unit is aimed at stores, pharmacies, and cold-storage operations that may need phased upgrades rather than a full system swap. [Variable-speed compressor control](https://www.trendhunter.com/trends/heating-and-cooling-unit) adjusts output to demand, while removable panels and accessible service points make maintenance and diagnostics less disruptive. Its electrical options also make it easier to integrate with existing infrastructure. With a global warming potential of 1, the unit has a clear compliance story as refrigerant rules tighten. By combining compact hardware with service-friendly construction, it gives operators a path to update cooling capacity without rebuilding the whole system at once.
