In an era where consumer demand for fresh, high-quality food is at an all-time high, the journey of goods from farm to table has never been more critical. The success of this journey depends on an efficient and reliable supply chain, and one of the key contributors to this process is the transport refrigeration units. These specialized systems play a pivotal role in ensuring that perishable goods maintain their quality and freshness from the moment they leave the farm to when they arrive at your local grocery store—or even your own kitchen. Sinoclima is committed to ensuring the freshness of goods.

When selecting refrigeration units for trucks, factors such as the volume of the compartment, the temperature requirements of the goods to be transported and the transportation mileage should be taken into account. Next let me make a specific introduction.

What kind of information is needed to make the right choice? Choosing a transport refrigeration unit depends on many factors. All this information should be provided before ordering the unit.

Internal and external lengths of the truck bodies.
Internal and external width of the truck bodies.
Internal and external height of the truck bodies.
Ambient temperature.
Temperature required inside compartments.
Products to be transported.
Number of door openings
K factor of the body
Road operation and/or standby operation,
Type of use (long-distance transport, local distribution, etc.).
Other useful information.

Warming Tips for drivers using refrigerated trucks:
1, The refrigerated truck must be equipped with a spare belt, tensioning wheel, fuses, and other wearing parts.
2, Regularly check the tightness of the belt.
3, Regularly clean the condenser to maintain good heat dissipation and avoid high-pressure alarms.
4, Use for more than a year, it is better to go to the service station to do the maintenance.
5, Before loading the goods, Please pre-cool for 20 minutes to check the refrigeration units have no fault! Do not wait until the goods are loaded, only to find that the truck refrigeration unit has a fault. You can check whether the condensing fan, evaporating fan, and compressor are working normally.

LPER alarm code appears on the refrigeration unit, probably the expansion valve is blocked by ice

The phenomenon of ice blockage of the expansion valve :
1, Most of the goods in the box are frozen or pulling goods below zero
2, First period, refrigeration units are cooling down normally, shut down after a period of rest or after the end of the cold machine defrost to refrigeration mode, found that the truck refrigeration machine does not cool down for a long time.
3, The van&truck refrigeration units display a low-pressure alarm (alarm code LP/LPER/A01, etc.) or the refrigeration units do not cool down for a long time, with no alarm.
