Applications
There are two main atmospheres: RA – Regular atmosphere (21% O
2
), and CA - Controlled Atmosphere
(1.5% - 5%).
There are six main room types: Pre-Cooler (RA), Cold Storage (RA), Processing Rooms (RA), Food
Preparation or Kitchen Facility (RA), Odor Control (RA), and Cold Storage (CA).
There are five main categories of commodity or applications: Fruits & Vegetables, Meats, Seafood, Flowers,
and Odor Abatement.
Depending on the atmosphere, commodity, and temperature, the EMS-3000 Series System has been
configured to meet the application. Some important information to note:
Flowers: The ozone (O
3
) levels should average 0.030ppm and not exceed 0.040ppm.
Processing Rooms, Food Preparation and Kitchens: The ozone (O
3
) levels should average 0.050ppm.
Odor Control: Depending on the application the ozone (O
3
) levels can be stronger if needed,
especially with limited exposure to workers/customers.
CA (Controlled Atmosphere): The EMS-3000 Series Purifier should not be ON until the oxygen (O
2
)
level has reached 10% or lower.
System Operation Example
The EMS-3000 Series System constantly balances output in response to the monitored ozone conditions to stay
within the programmed limits. Three control points are defined during the installation, which are used to calculate
the activation of high or medium output when the 3000 Series System is in operation.
To illustrate the typical operation of the EMS-3000 Series System, an example setup is listed below using the
following ozone level settings:
Low Control Point:
0.020ppm
Med Control Point:
0.030ppm
High Control Point:
0.040ppm
To show the possible balancing operation that would result using the above example control points, Figure 16 lists
the ozone level as well as the Medium and High activation status indicators in a chronological order:
