High-pressure processing equipment maker Hiperbaric will debut the Hiperbaric 525 with 12 intensifiers at PACK EXPO International 2026 — a configuration the company says sets a new cycle-rate benchmark for the 525-gallon vessel class, with direct implications for seafood and shellfish processors operating under tight margins and tighter plant floors.

HPP has become a standard kill step across the seafood supply chain, widely used on ready-to-eat shellfish, cold-smoked salmon, crab meat, shrimp, and oysters. The non-thermal process — applied at up to 6,000 bar (87,000 psi) via cold water — inactivates Listeria monocytogenes, Vibrio, and other aquatic-protein pathogens without heat damage, preserving the fresh texture and color that command premium dockside and retail price points.

Throughput and Footprint

The H525's 12-intensifier configuration completes up to 10.7 cycles per hour at 6,000 bar, a 3-minute holding time, and 60 Hz frequency — figures Hiperbaric says outperform comparably configured competing systems under identical test conditions. The machine ships in two layouts: a Standard configuration requiring 1,000 square feet at 8.9 feet of ceiling height, with intensifiers at floor level; and an Integrated configuration that mounts intensifiers on a built-in mezzanine, compressing the floor footprint to 940 square feet while rising to 16.5 feet. For seafood processors running automated tray-seal or vacuum-pack lines, the Integrated layout frees adjacent floor space for upstream portioning or downstream checkweighing without expanding the building envelope.

An integrated return conveyor eliminates up to 20,000 pounds of manual canister lifting per shift — a figure with real ergonomic and workers'-compensation relevance in facilities processing high volumes of portioned crab clusters, lobster tails, or IQF shrimp packs. Existing H525 installations can be upgraded to the 12-intensifier configuration, and Standard units can be converted to the Integrated mezzanine platform, preserving capital already deployed on the floor.

Independent Intensifiers

Each of the 12 intensifiers is independently isolatable — a design Hiperbaric claims is unique in the HPP industry. A technician can pull one unit for service while the remaining 11 continue pressurizing product, avoiding the full-line shutdowns that squeeze throughput windows in time-sensitive seafood operations. Because Hiperbaric manufactures its intensifiers in-house, the company says it continuously updates performance parameters using field data from an installed base that now exceeds 450 machines globally.

"Processors are being asked to do more with the same building," said Rob Peregrina, USA Executive Director of Hiperbaric. "The 525 with 12 intensifiers gives them the highest throughput we've ever built into a 525-gallon platform, and the Integrated configuration delivers that throughput in a footprint that's a fraction of what comparable systems require."

Support Infrastructure

Every machine ships with the Hiperbaric HPP Support Program at no ongoing cost: 24/7 remote troubleshooting, on-site field engineers within 24–48 hours, and spare-parts warehouses in the United States, Mexico, Spain, and New Zealand committed to sub-24-hour shipping. Complimentary food-science process authority support is included — a meaningful resource for seafood brands navigating FDA process filing requirements for HPP shellfish products.

Hiperbaric will present "Clean Label Meets Food Safety with High Pressure Processing" on October 19 at the Processing Innovation Stage (Booth LU-7764) during PACK EXPO International at McCormick Place in Chicago. Seafood operations evaluating cold-pressure technology for value-added shellfish programs or retail-ready IQF lines will find the session and booth relevant to current capital planning cycles.
