Tru-fog Crop Hydration®
Maximise pick weight, quality & shelf life by maintaining or improving natures freshness. You and your customers will see the benefits of our Tru-fog:
- Tru-fog sustains life through natural hydration using ultra-pure water in the form of minute
- Tru-fog is absorbed naturally, being smaller than the stomata in the leaves
- Tru-fog is too small to freeze and has no adverse effect on modern refrigeration
- Defrost cycles need not be increased
- Tru-fog promotes faster, more efficient cooling with less energy used
- Enables lower core temperatures to be achieved without detriment to the product
- The amount of energy used by the refrigeration to remove heat will be reduced through the evaporative effect of this cold-water humidification system
- Working visibility is maintained within the fog and does not affect forklift trucks or electrical equipment

We take a natural science and control it …simply… in the cold store or retail store
Tru-fog will only rehydrate produce through the stomata – a natural solution. Water alone cannot enter the stomata. When dehydration takes place, plant cells shrink and the stomata closes to reduce vapour loss. In a Tru-fogTM environment the stomata will open to absorb moisture if needed. During rehydration only our Tru-fog of
Natural Absorbtion
Hydration occurs through the pores or stomata of plants, vegetables and soft fruits. Once picked, produce dries out very quickly in refrigeration! Tru-fogTM sustains life through natural hydration using ultra-pure water, in Tru-fog particles, which float in the air – reaching everywhere.
Weight Maximised
Maximise pick weight and yield by rehydration. Only Tru-fog can regenerate produce this effectively. Tru-fogTM only produces droplets
Plump Appearance
Both you and your customers can see Tru-fog and how it benefits the product, which remains in perfect condition.

Tru-fog explained
Ultrasound vibration is used to produce our unique Tru-fog. By creating a light but visible fog with droplets of ultra-pure, demineralised water suspended in the atmosphere, leafy salad and vegetable products rehydrate to maintain maximum pick weight, quality and shelf-life. Our system goes far beyond standard humidification, Tru-fog gets everywhere and there is visible proof that it works – without wetting the produce or the floor. The system enables companies to maintain the quality of their product and maximise yield in a competitive market.
Feedback – What our customers say…
- The Pendred Tru-fog Crop Hydration system has revolutionised our farming operation.
- We are now selling baby leaf product at up to 11 days after harvest without any Quality issues.
- If we can, we prefer to hold product for one or two days in our Tru-fog conditioning cold store as product looks better after two days in storage than it does fresh from the field.
- We are consistently recording a 10% increase in product sent to processors (same at our other satellite farm) since we installed the Pendred Tru-fog system.
- This season we have had absolutely no product wasted due to quality issues.
- Much greater flexibility and reduced cost in cropping now that we can plan a week ahead rather than reacting to orders received that day. We call this ‘strategic cropping’, since the introduction of the Pendred Tru-fog system, we cut in advance rather than on the morning of despatch.
- The despatch weight of product is exactly matched to the order weight, as stabilised product comes directly from the cold room, not the field.
- Health and Safety is vastly improved as a result of planned work schedule.
- Costs are reduced as we no longer have to re-visit the field to make up order weight.
- We can now cut and store leaf at the optimum or correct size, preventing leaf from growing oversize in the field and being wasted.
- The Pendred Tru-fog Crop Hydration system has revolutionised our farming operation.
- There is now a potential to grow and store surplus crop before the latter end of the season when the yields are poor and danger of frost damage is imminent.
- Over production caused by crops bolting can now be held in store and sold rather than being wasted.
- Bunched carrots look better than they did off the field.
- Beetroot has held for months with no loss of quality or weight.
- Broccoli can be held in perfect condition for 5 weeks or more.
- “We won’t be able to manage without it!” – (Brassicas, bunched carrots, beetroot).
- Broccoli lost 2% weight in three weeks and was in perfect condition, the control sample lost 22% and was not in saleable condition
- For such a simple concept the results are amazing
- If bad weather is on its way we can cut and store product before it is ruined on the fields
