Used Henny Penny blast chiller/freezers in great condition.

Quickly cool hot foods for cold service, storage, or later rethermalizing.
Chills up to 24 lbs. (11 kg) per cycle of food properly portioned in pans or other containers.
Blast chill to 40°F (4°C) or blast freeze to 0°F (-18°C).

Removable, adjustable shelf runners accept full-size steam table pans and grids.
Food safety is enhanced with minimal energy consumption.
Greater flexibility in production and increased equipment utilization.
Foods that are blast chilled also store longer, taste better when reheated and retain their color, flavor and texture longer since very little moisture is lost through evaporation
