(Philadelphia, PA, USA) Humifresh® Ultra High Humidity Precoolers and Room Coolers, offer the highest capacity, airflow, and pressure capabilities available.
Humifresh® is the originator, and leading manufacturer of Precoolers worldwide, being the successor company to the original inventor, Meredith & Simpson, that pioneered “Filacell®” water-driven cooling systems in the 1960s, in California.
"Precooling" – which is the term for quickly reducing the temperature of fresh harvested fruit and vegetables, to ideal temperatures – greatly helps to extend the shelf life and net weight to sell, of almost all fresh produce. The Humifresh® design provides for Ultra High Humidity airflow, often 95% to 98%.
Air-handling equipment that forces large volumes of humid, cool air, through the tiny holes in corrugated boxes and plastic crates – and the liners, bags, and consumer packs within them – can encounter very high “static pressure” resistance to that airflow.
The faster that the fresh-cut fruit, vegetables, or flowers, can be brought down from field temperatures, to ideal storage temperatures, the longer the shelf life, the better the quality, and the less the weight loss. Ultra High Humidity airflow is also a large benefit to all of the above.
Humifresh® now offers models that have capacities as high as:
• Airflows as high as 50,100 cubic meters per hour (30,000 cfm);
• Static Pressure capability as high as 600 Pascal’s (2.4 inches of water column); and
• Refrigerating Capacities as high as 137 kilowatts per hour (468,575 BTU’s per hour.)
These larger capacities, can be applied to a small number of pallets, to dramatically decrease Precooling time. Or, applied to a larger number of pallets, to increase lot size and throughput.
Reducing produce temperatures as quickly as possible, also improves upon food safety, as at lower temperatures, “blooms” of CFUs are much less likely to occur. Better Cold Chain Management equals improved food safety.
Global Cooling has completed a number of Ripening, Precooling and Refrigerated Warehouse projects in the Philadelphia region, and has also worked in 5 of the 7 continents, worldwide.
