The CITIMAX 350 is a compact truck refrigeration unit designed to help maintain controlled temperatures in refrigerated transport bodies. In practical terms, buyers should evaluate it as a vehicle-mounted cooling solution rather than relying on the model name alone to define performance. The final specification depends on the vehicle, body volume, insulation, operating climate, power arrangement, refrigerant configuration, and required cargo temperature.
At ACOOLER, I recommend confirming the complete technical configuration before placing a commercial order. The most important questions are whether the unit is suitable for the truck body size, whether it supports the required temperature range, how it is driven by the vehicle, and what installation and service support will be available in the destination market.
The CITIMAX 350 belongs to the CITIMAX range of truck refrigeration equipment used for temperature-controlled distribution. It is generally considered for refrigerated trucks and box bodies that need active cooling during transport, loading, and delivery operations. The unit works with the vehicle refrigeration system to remove heat from the cargo compartment and reduce temperature rise during normal distribution cycles.
For B2B buyers, the model designation should be treated as a product identifier and capacity class reference, not as a complete performance specification. Cooling capacity can change according to ambient temperature, engine speed, evaporator arrangement, body insulation, and operating mode. I therefore advise buyers to request the applicable performance table for the exact configuration rather than comparing model names in isolation.
The primary function is to maintain the cargo temperature after the load has been properly pre-cooled. This distinction matters because a transport refrigeration unit is normally selected for temperature maintenance and controlled pull-down, not for rapidly cooling warm products in an overloaded or poorly insulated body. The required result depends on product temperature at loading, door-opening frequency, route length, and air circulation.
The CITIMAX 350 can be considered for delivery routes where the vehicle may stop several times and doors may open repeatedly. Each opening introduces warm air and increases the refrigeration load, so body insulation and operating discipline remain essential. Buyers should assess the expected number of daily stops rather than selecting equipment only from the nominal cargo volume.
Typical application discussions include fresh produce, dairy products, meat, seafood, prepared foods, flowers, and other temperature-sensitive goods. A specific product should only be transported after the shipper confirms its required temperature range and handling conditions. For pharmaceutical or other regulated cargo, the complete vehicle system must be validated for the intended route and product; the refrigeration unit alone does not establish regulatory compliance.
The most important configuration factor is the truck body. A short urban box truck, a medium distribution body, and a larger insulated body can impose very different heat loads even when they operate in the same climate. I normally review body length, width, height, wall thickness, door design, floor construction, and the presence of bulkheads before recommending a configuration.
Truck refrigeration systems may be matched to the vehicle’s electrical and mechanical arrangement, depending on the product version and installation design. The available vehicle voltage, alternator capacity, engine compatibility, mounting position, and belt or compressor arrangement must be confirmed with the installation documentation. A common commercial vehicle electrical reference is 12 V, but buyers should not assume that every CITIMAX 350 installation uses the same electrical specification.
Fresh and chilled distribution commonly operates around 0°C to 5°C, while frozen transport may require approximately -18°C or lower. These figures are cargo-handling examples, not a blanket performance claim for every CITIMAX 350 configuration. Before purchasing, specify the cargo set point, maximum ambient temperature, required pull-down time, and whether heating or defrost functions are needed.
The evaporator arrangement affects air distribution, available cargo space, and installation clearance inside the body. Control features may include temperature monitoring, automatic control, defrost management, and driver-facing status information, subject to the selected version. For fleet buyers, I recommend checking whether the control interface and service parts are suitable for the vehicles already operating in the fleet.

A reliable purchasing specification should include more than the product name. The following table identifies the technical areas I suggest confirming with the supplier, installer, and vehicle manufacturer before issuing a purchase order.
| Specification area | What the buyer should confirm | Why it matters |
|---|---|---|
| Cooling performance | Capacity at stated ambient and box temperatures | Shows whether the unit can handle the actual heat load |
| Temperature range | Chilled, frozen, or multi-temperature requirement | Prevents a mismatch between cargo needs and equipment capability |
| Power system | Vehicle voltage, alternator demand, compressor and mounting requirements | Supports safe and practical installation |
| Body compatibility | Internal volume, insulation, doors, airflow, and evaporator clearance | Determines actual cooling load and usable cargo space |
| Service requirements | Maintenance intervals, spare parts, diagnostics, and local support | Influences lifetime operating cost and fleet availability |
The “350” designation should not be used as a substitute for a measured capacity figure. Where cooling capacity is listed, the test condition must also be stated because a value measured at one temperature condition cannot be directly compared with a value measured under another. I recommend requesting capacity data in watts or another clearly identified unit, together with the evaporating temperature, ambient temperature, and operating mode.
The unit may suit refrigerated delivery trucks serving supermarkets, restaurants, wholesalers, and food-service operators. These routes typically require frequent door openings and consistent temperature recovery between stops. The buyer should therefore prioritize airflow, door management, insulation quality, and service access in addition to nominal cooling performance.
Fresh produce, dairy, beverages, meat, and seafood can have different temperature and humidity requirements. The CITIMAX 350 should be matched to the product specification rather than selected solely because the vehicle is described as refrigerated. Proper pre-cooling and load arrangement are necessary to avoid blocking air circulation and creating temperature variation inside the body.
Flowers and certain specialty goods may benefit from controlled transport conditions, but they may require airflow and temperature settings different from those used for frozen products. A shipper should define acceptable temperature limits, maximum route duration, and packaging constraints before selecting the equipment. If the cargo is especially sensitive, temperature recording and route validation should be included in the project plan.
A practical example is a multi-stop urban route with a target of 2°C and frequent door openings. In this case, body insulation and recovery behavior may be more important than maximum theoretical capacity. A long-haul frozen application at -18°C may require a different evaluation, particularly in hot ambient conditions, and should be confirmed through the relevant performance data.
At ACOOLER, I support buyers by organizing the technical information needed for product matching, quotation, and export coordination. We can review the vehicle type, refrigerated body dimensions, target temperature, operating environment, and installation expectations before recommending an available CITIMAX 350 configuration. This approach helps reduce the risk of ordering a unit that is difficult to install or insufficient for the intended route.
For fleet and distributor projects, I can also help structure the inquiry around quantities, packaging, spare parts, documentation, destination market, and delivery requirements. Exact lead time, minimum order quantity, warranty coverage, and replacement-part availability should be confirmed for each project because they may vary by configuration and destination. Buyers should request the current product datasheet and quotation before making a final technical decision.
The CITIMAX 350 may be a suitable choice for refrigerated truck applications when its confirmed cooling performance and installation configuration match the vehicle body, cargo temperature, climate, and route conditions. The correct decision cannot be made from the model number alone. A complete technical review is the safest way to determine whether it fits fresh, chilled, frozen, or specialized distribution.
To move forward, prepare the truck model, body dimensions, insulation details, cargo type, target temperature, ambient range, route pattern, and quantity requirement. Send these details to ACOOLER for configuration review and a project-specific quotation. I can then help you verify the available CITIMAX 350 specification, installation requirements, documentation, and supply support before you place an order.
