Dual Refrigerated & Dual Genset Container

MODEL NMR-872 & NMG-115

» Two full capacity reefer units offer total redundancy—each reefer has their own thermostat and control circuit
» Two generator sets offer total redundancy—each genset capable of powering the reefer units
» Complies with international regulations for the transport of dangerous goods
» Provides the ultimate protection with two reefers & two gensets

Klinge’s Dual Refrigerated Container has two full capacity reefer units. The refrigeration system, Model NMR-872, and generator sets, Model NMG-115-11, automatically switches to its back-up in an emergency to provide the ultimate peace of mind when shipping hazardous cargo or valuable cargo. The system complies with the International Maritime Organization’s regulations for transporting certain Dangerous Goods.

Klinge’s Dual Refrigerated & Dual Powered Containers have been used to transport millions of dollars of ice cores from the southern hemisphere, across the equator, and through the southwestern United States. Using Klinge’s equipment, the ice cores were not permitted to drop below -20°C at any point during their 1.5-month travel. Otherwise some of the most critical research related to analysis of the gases contained in the cores would not have been possible. Fill out the form or call +1 717-840-4500 to learn more.

» Each system is solely capable of maintaining the required cargo bay temperature setpoint.
» Only one system can operate at one time; they are not designed as lead-lag or automatic-alternating systems.
» Main power to the refrigeration unit is 380/460 volts 3 phase, 50/60 Hz electrical power (provided either from “shore” power through an onboard voltage transformer, or via one of the integral gensets).
» The control circuit voltage is reduced to 20/24VAC.
» The refrigeration unit has a welded aluminum frame, aluminum doors and closures, and steel hardware.
» The electrical section consists of two electrical systems, one complete electrical system for each unit.
» The thermostats control the temperature of the cargo space. Each system has its own thermostat and temperature sensing probes.
» Each system also has its own compressor, evaporator motor and condenser motor (the two condenser motors are in one frame). Only one compressor will operate at any time.
» System 1 operates with 10.5 lbs of R-404a refrigerant charge. System 2 operates with 11 lbs of R-404a refrigerant charge.
