XtendFRESH™
The XtendFRESH™ atmosphere control system is a
modular option that offers enhanced functionality
to help slow the ripening process of perishable
cargo by removing ethylene and simultaneously
controlling CO and O levels in multiple combina-
2 2
tions. This enables the fresh transport of perisha-
bles on longer voyages. The system's ability to
control the container atmosphere is performed
with the use of a CO and ethylene scrubber. In
2
this article, we will review the key features and
operation of the system.
Starting the Refrigeration Unit
Caution: Check that the unit circuit breaker and start-
stop switch are in the OFF ("0") position before con-
necting to any electrical power source.
1. Check power source for proper voltage.
2. Connect the refrigeration unit power plug and turn
the main power ON.
3. Turn the refrigeration unit circuit breaker ON ("1").
4. Start the refrigeration unit by turning the start stop
(ST) to ON (position ("1").
Notes: Turn the start-stop (ST) switch OFF (position "0")
to stop the unit, also turn the unit circuit breaker OFF.
Recommend the latest operational software be installed
in the unit prior to troubleshooting.
Potential hazardous atmosphere and low oxygen levels
inside the container, ventilate before entering. Stay away
from doors while venting.
