Delivers Fresh Without the Wet

Préserve emits a hydrating fog of humidity creating a cooling effect that surrounds produce.

  • True dry fog (non-wetting)
  • Quiet operation
  • Maintains proper humidity levels throughout the case
  • No FDA mandated service contract required
  • Clean, closed plumbing system exceeds health department requirements
  • Reduces all produce shrink
  • Installed with misting for added moisture barrier
  • Self-sanitization that cleans system, the service case and extends produce life
  • No compressed air needed
  • Very low maintenance
  • Rolling fog attracts customers

Produce Preservation System

When the industry asked for a produce fogging system, our engineers got to work. They knew it needed to stay true to Corrigan’s mission to provide simple and reliable equipment that is easy to maintain. Using these core values, Préserve is engineered to be unlike any other fogging system on the market.

This comprehensive perishable preservation system creates optimal environmental conditions to protect and preserve produce.

Préserve’s patent-pending technology surrounds produce with high levels of dry fog humidity to prohibit transpiration, reduce shrink and extend produce life.

The Four Components of a Préserve System

HyperSoft Series Reverse Osmosis

Produces high quality water to the system and the produce throughout the case.


5-micron dry fog nozzles raise humidity levels throughout the case protecting produce.


Activated oxygen technology (ozone) is fully integrated to safely sanitize the system and service cases by greatly reducing microbiological loads. Ozone is proven to increase the shelf life of fruits and vegetables.


Produces a gentle 25-micron dew-like mist creating a fresh appearance and protective moisture barrier on produce.

Water and Energy Savings

Savings Statement Savings Factors
Préserve’s dry fog water usage is optimized for precise humidity control
  • Water usage is 52.5% less than a standard produce misting system
  • Water usage is 30% less than marketed fog and mist combination products
Préserve’s dry fog high humidity level control reduces produce shrink rate at store level
  • Préserve utilizes a 25W power supply per 8-foot section
  • Fog and mist combination compressor units use approximately 600 W
  • Ultrasonic Nebulizer units that blow dry fog from a tank reservoir use 500W blower/control systems
  • Some European retailers use high humidity perishable preservation without any refrigeration for produce resulting in energy savings
Préserve’s dry fog electricity consumption is lower than other systems
  • Less water usage required in agriculture
  • Less trucking energy from field to consumer
  • Less transportation of workers to handle produce
Préserve’s materials of construction are recyclable
  • Stainless steel, recyclable plastics, and recyclable metals are utilized in all assemblies
