Frequently Asked Questions

Why do you need humidification in the perishable products industry?

Relative humidity maintains product quality and extends shelf life. Temperature, relative humidity, air movement, thermal radiation and structural design all interrelate to create conditions that enhance or detract from product quality. The overall weight, quality and freshness of products are immensely affected by changes in these environmental variables.

What does temperature have to do with relative humidity?

Temperature is the key to understanding relative humidity. Warm air has the capacity to hold more moisture than cold air. This is especially true with service cases, which often have lower operating temperatures resulting in less humidity, which can negatively affect the product.

How can relative humidity increase sales?

Meat, seafood and poultry have a high percentage of moisture as shown in the table below. The loss of moisture is a major factor in contributing to product weight loss; drop in quality and deterioration of product color.

By maintaining the proper relative humidity level, the drying effect of the cold temperature and circulating air is dramatically reduced, as well as improving the meat bloom, making it more appealing to today's discerning consumers. Thereby increasing sales through extended shelf life.

How much can a Puremist humidification reduce shrink?

Research shows a dramatic reduction in shrinkage resulting from the use of humidification in service cases. The following tables compare the shrinkage in a meat case and a deli case in a typical supermarket.

$ 9,100

Note : Actual shrink results will vary epending on case configuration, maintenance and store personnel use.

These savings are based upon and average weekly loss of 6.5% for meat cases and 3.5% for deli cases and a documented benefit of shrink reduction of approximately 50%.

In today's 24-hour format maintaining proper moisture levels is especially difficult as store personnel are not constantly present.

What types of technology does Puremist use in its humidification systems?

Our humidification systems utilize High Pressure water atomization technology to create a light fog. The systems use a humidity controller and sensor that can automatically maintain desired humidity levels up to 95%. O ur system can also connect directly to the specific facilities control system.

Does Puremist install and maintain humidification systems?

Yes, Puremist Corporation has manufactured, installed and serviced perishable control systems for over 25 years. We have the in-house technical expertise, along with parts and equipment to get the job done on time and on budget.
