The CITIMAX 280 is a truck refrigeration unit that buyers should evaluate by confirmed cooling performance, vehicle compatibility, cargo temperature, installation method, and service requirements—not by the model name alone. I recommend requesting the latest manufacturer datasheet before comparing quotations because available specifications, options, and regional configurations may differ. In this guide, I explain how to assess a CITIMAX 280 application, which technical details to confirm, and how ACOOLER can support specification review and sourcing for emergence vehicles and commercial transport projects.

The most important starting points are the required temperature range, body volume, route length, ambient conditions, door-opening frequency, and vehicle electrical or engine configuration. For chilled distribution, a buyer may need a cargo target around 2°C to 8°C; for frozen products, the requirement may be approximately -18°C or lower, depending on the product and applicable rules. These targets must be checked against the unit’s official capacity data at the relevant ambient temperature rather than assumed from the “280” designation.
This guide is intended for fleet operators, refrigerated-body manufacturers, food and pharmaceutical distributors, vehicle upfitters, importers, and procurement teams comparing truck refrigeration solutions. It is also useful for buyers who have received a CITIMAX 280 quotation but do not yet have enough information to verify the configuration. I focus on practical purchasing decisions rather than treating the model name as a complete technical specification.
The guide is especially relevant when the buyer must coordinate the refrigeration unit with a truck chassis, insulated box, evaporator position, control system, and maintenance network. It can also help project teams prepare a technical inquiry that reduces quotation errors. For regulated cargo, I recommend involving the quality or compliance team before final equipment selection.
CITIMAX is associated with truck refrigeration equipment used to protect temperature-sensitive cargo during transport. However, the exact meaning of “280” should be confirmed from the current product documentation supplied for your market and configuration. It should not automatically be interpreted as a guaranteed cooling capacity in watts, a cargo-box volume, or a temperature rating.
A complete specification normally includes cooling capacity at stated conditions, refrigerant information, power source, operating temperature range, evaporator configuration, control interface, dimensions, weight, noise data, installation requirements, and service intervals. Without these details, two quotations carrying the same model name may not be directly comparable. I therefore treat the model designation as an identification point and the datasheet as the purchasing reference.
I recommend asking the supplier to present every performance value with its test condition. A cooling-capacity number without an ambient temperature, box condition, or operating mode can be misleading. The following table provides a practical specification framework for your request for quotation.
| Specification area | What I would request | Why it matters |
|---|---|---|
| Cooling performance | Capacity in watts or kilowatts at defined ambient and box temperatures | Allows a fair comparison with the calculated heat load |
| Temperature application | Chilled target, frozen target, operating range, and pull-down conditions | Prevents an unsuitable unit from being used for the cargo |
| Power source | Vehicle voltage, engine-driven or electric arrangement, current draw, and protection requirements | Confirms compatibility with the chassis and installation |
| Vehicle body | External dimensions, insulation thickness, internal volume, door configuration, and body material | Determines heat ingress and installation space |
| Service requirements | Refrigerant type, filter or belt requirements, diagnostics, maintenance access, and spare parts | Influences operating cost and fleet uptime |
As a basic screening reference, many chilled-food operations work around 5°C or below, while frozen-food logistics commonly use a target near -18°C. These are application references, not a claim about CITIMAX 280 performance. The U.S. Food and Drug Administration identifies 5°C as a cold-holding reference in the Food Code, while the Codex General Principles of Food Hygiene provides internationally recognized food-safety guidance; buyers should still follow the requirements for their product and destination market.
For vehicle integration, confirm whether the truck uses a 12 V or 24 V electrical system before approving an electrical configuration. Also record the box internal length, width, and height in millimetres, payload in kilograms, route duration in hours, and typical ambient temperature in °C. These five measurable inputs give the supplier a more reliable basis for heat-load review than a general request for “a powerful unit.”
Chilled distribution usually involves frequent stops, repeated door opening, and a requirement to protect product temperature during loading and unloading. I would check the unit’s performance under high ambient conditions, the airflow arrangement, and the body’s insulation quality. A refrigeration unit cannot compensate indefinitely for open doors, warm product loading, damaged seals, or inadequate insulation.
Frozen applications place greater demands on low-temperature operation, defrost control, insulation, and pre-cooling discipline. Before purchase, ask whether the quoted configuration is specifically rated for the required frozen temperature and whether the published capacity applies at that condition. The buyer should also define whether the unit is expected to maintain already frozen cargo or pull down warm product, because these are different thermal duties.

For emergency vehicles, I recommend evaluating more than cooling capacity. The project may require compact installation, dependable temperature visibility, low electrical risk, rapid access for service, and compatibility with auxiliary equipment. Vehicle body layout, medical or emergency equipment, standby power, and operating noise may affect the final configuration, so ACOOLER can help organize these requirements into a supplier-ready specification.
The first decision is whether the unit will maintain pre-cooled cargo or also cool down warm cargo. The second is whether the truck’s daily route requires engine-driven operation, electric standby, or a combined arrangement. The third is whether the customer needs standard supply or customization involving mounting brackets, control interfaces, wiring, body adaptation, or monitoring.
Price should be considered after technical suitability has been established. A lower initial quotation may exclude installation materials, control components, insulated-body work, commissioning, or spare parts. I recommend comparing the complete delivered scope, including packaging, documentation, testing, shipping terms, and after-sales support.
Customization should begin with the vehicle and cargo requirements, not with cosmetic changes. Depending on the project, I can help buyers organize requests for mounting adaptation, evaporator positioning, electrical interface review, control-panel requirements, monitoring integration, packaging, labeling, and export documentation. The final feasibility depends on the original unit design, vehicle body, local regulations, and the approved engineering drawings.
For a multi-vehicle order, I recommend creating one approved configuration and then controlling any deviations by revision number. This approach reduces inconsistent wiring, mounting differences, and spare-parts complexity across the fleet. It also gives the buyer a clearer basis for inspection before shipment.
CITIMAX 280 pricing can vary according to configuration, quantity, destination, installation scope, freight terms, and customization. I do not recommend using an unverified online price as a purchasing benchmark because a refrigeration unit may be quoted without brackets, controls, installation, commissioning, or spare parts. Instead, request a line-item quotation showing the equipment scope and any optional items separately.
MOQ and lead time should also be confirmed for the exact configuration. A standard unit may follow a different production schedule from a customized project requiring engineering approval or special packaging. Before issuing a purchase order, ask for the production lead time in calendar days, quotation validity in days, warranty duration in months, and the required payment and inspection milestones.
For regulatory review, I suggest consulting the applicable authority in the destination market rather than relying only on a supplier statement. For food transport, the FDA Food Code and Codex food-hygiene guidance are useful reference points, while international road-transport requirements may involve national rules or agreements such as ATP where applicable. The official ATP text is maintained through the United Nations Economic Commission for Europe (UNECE), and its applicability should be confirmed for the intended route and cargo.
The best way to buy a CITIMAX 280 is to match the verified unit configuration with the cargo temperature, insulated-body heat load, route conditions, vehicle power system, and service plan. I recommend preparing a one-page requirement sheet with the target temperature, body dimensions, payload, ambient range, operating hours, door frequency, voltage, and customization needs. Then request a documented quotation with performance conditions, installation scope, lead time, and warranty terms.
ACOOLER can support B2B buyers by reviewing application information, organizing technical questions, coordinating configuration discussions, and preparing a sourcing proposal for emergence vehicles and other refrigerated transport projects. Send the vehicle model, body dimensions, cargo type, temperature target, quantity, destination, and expected delivery schedule for an initial feasibility review. I will use those details to help identify the information that must be confirmed before the CITIMAX 280 configuration is approved.
