Patterson-Kelley is based in Allentown, Pennsylvania, and its current official site (pattersonkelley.com) is part of the SPX Technologies family: the site footer links to spx.com and its news page welcomes recent acquisitions into 'the SPX Technologies Family'. The earlier parent, Harsco, sold the Patterson-Kelley business to SPX Corporation in December 2019 per Harsco's official press release — the 2019 P-K site footer read 'Harsco Industrial Patterson-Kelley is a division of Harsco Corporation'.
The current commercial boiler menu splits into condensing boilers — P-K SOLIS (vertical firetube, 96%, 10:1), P-K STORM (stainless steel, 97% thermal, 10:1), P-K SONIC (stainless steel, 97%, 5:1) and P-K MACH — and non-condensing boilers — P-K MODU-FIRE FD and P-K THERMIFIC VELOX. The 'Velox' name belongs to the P-K THERMIFIC VELOX line; no standalone Velox brand exists.
No official Canadian availability statement was found on the captured P-K pages; the site's rep locator covers reps and country data were not text-captured, so canadianStatus is recorded as unknown. Boilers.ca does not print per-model rating tables beyond what the official pages state.
Series
Each series hub lists its models, verified specifications, manuals and documented alerts.
The P-K SOLIS is Patterson-Kelley's condensing vertical firetube boiler — 96% efficiency, 10:1 mechanical turndown and ultra-low NOx per the official page — with per-model sizes documented in P-K submittals rather than the page copy.
The P-K STORM is Patterson-Kelley's stainless-steel condensing boiler, operating at 97% thermal efficiency with 10:1 mechanical turndown per the official page, with model families sized through the 4000 MBH range in the family-page documentation rows.
The P-K SONIC is Patterson-Kelley's stainless-steel condensing boiler operating at 97% efficiency with a 5:1 turndown and ultra-low emissions, with model families documented through the 4000 MBH range on the family pages.
The P-K MACH is Patterson-Kelley's condensing boiler line for 'a wide variety of commercial and industrial building applications, including new construction as well as retrofit projects', with family documentation rows referencing from the 300/399–500 MBH range upward.
The P-K MODU-FIRE FD is Patterson-Kelley's forced-draft non-condensing boiler line in six models — N750, N1000, N1500, N2000, N2500 and N3000 — with a full-modulation design that 'changes both fuel and air at a constant ratio to match boiler output to actual heat demand', smooth 5:1 turndown tracking down to 20% of rated capacity and up to 88% efficiency.
The P-K THERMIFIC VELOX is Patterson-Kelley's packaged non-condensing boiler line in five models — N750, N1000, N1500, N1700 and N2000 — with a vertical design and radial-fired fan-assisted burner, a CSA certified thermal efficiency of 85% as a Category I non-positive appliance, and only five connections required for installation, even on combustible floors.
