Fresh Air Exchange System
The fresh air exchange system removes harmful gases from containers carrying sensitive perishable
commodities. The fresh air vent is located above the control box. The fresh air vent is adjustable to
accommodate a variety of frozen and chilled load operating conditions.
Receiver Tank Sight Glass
The receiver tank contains a sight glass which has three small balls that indicate the level of refrigerant in
the tank for checking the refrigerant charge. A moisture indicator in the sight glass changes color to
indicate the level of moisture in the system.
Evaporator Fans
MAGNUM models are equipped with either 2 or 3 evaporator fans. All models feature 2-speed motors.
The evaporator fans operate continuously to circulate air inside the container. The evaporator fans operate
on:
•
High and low speed for chilled cargo at setpoints of -9.9 C (14.1 F) and above
•
Low speed for frozen cargo at setpoints of
-10 C (14 F) and below
