FREQUENT QUESTIONS

How much does a reefer consume?
A 40-feet reefer consumes an average of 7 Kw/hour running normally; once the target temperature is reached, the engine will stop automatically.

How many HPs does a Reefer have?
Forty feet container:
·Compressor: 7.5 HP
·Evaporator engine: 2 HP
·Condenser engine: 2 HP

Twenty feet container:
·Compressor: 5.5 HP
·Evaporator engine: 2 HP
·Condenser engine: 2 HP

What is required to start a Reefer?
There must be three-phase energy supply equivalent to 15 kW or above, so as to stand the initial start of the engine.

After checking that the installations are adequate and safe, a reefer may be connected together with other engines. Inadequate connections may result in poor contact and may damage the container, burning the temperature control electronic plates as well as other components.

What voltage does a Reefer work with?
Reefers work with three-phase energy and 220, 380 and 460 volts.

Can the Reefer be connected to pole cables directly?
Yes it can, once it has an NH key with safety fuses.

The container has two cables, which one do I use to connect it?
Indeed, the containers have two cables. The yellow cable or the finer black cable is used to connect the container to 380 or 460 volts supplies. This cable is 4 x 6 mm, it is three-phase and the ground must always be connected. The thickest black cable should be connected to 220 volts, 4 x 10 mm three-phase; make sure the ground is always connected.

What circuit breaker can I use?
A 25 to 40 ampere tripolar circuit breaker must be used in 380 or 460 volts.
A 40 to 60 ampere tripolar circuit breaker can be used with 220 volts.

What are the main cautions required after installing a container?
Wash the container (specially the radiator in the engine) at least once a week.

Be careful not to damage the container carcass and do not make holes without due technical authorization from Multicontainer.
Only allow your company’s electrician to make repairs or maintenance work in the machine, but always with due training and/or guidance by our technicians on the telephone.

Is it normal for the engine to stop running?
Yes. The engine may stop running in order to keep temperature control. When the arrest is due to this reason, both the compressor and the condenser engine will stop, but both will keep an internal engine working.

For Defrosting
When the engines stop for defrosting all the engines stop, and only the resistances stay on for a 45-minute period.

By default
Whenever the engines stop for more than an hour, check if that was due to activation of the circuit breaker or a blackout.
At any rate, it is advisable to immediately contact Multicontainer’s technical assistance.
