If you are evaluating a CITIMAX 350 refrigeration unit, the safest buying decision depends on verifying the exact model plate, power system, installation configuration, and required cargo temperature before placing an order. The “350” designation alone should not be treated as a complete performance specification, because cooling capacity, voltage, refrigerant configuration, control system, and application range may vary by production version or vehicle installation. At ACOOLER, I recommend matching the unit to the emergency vehicle, truck body, insulation condition, operating climate, and temperature requirement rather than selecting by model name alone.
This guide explains what to verify, how to assess vehicle and cargo-body compatibility, which questions to ask a supplier, and how to reduce sourcing risk. It is intended for fleet buyers, vehicle integrators, emergency-vehicle manufacturers, refrigerated transport operators, and procurement teams comparing CITIMAX truck refrigeration units.
A CITIMAX 350 refrigeration unit is a vehicle-mounted cooling system used to control the temperature inside an insulated truck or special-purpose vehicle body. Its operating purpose is to remove heat from the cargo compartment and maintain a suitable temperature during transport, loading, and temporary stops. The actual result depends on the unit, cargo load, insulation, ambient temperature, door-opening frequency, and installation quality.
For emergency vehicles, the application may involve temperature-sensitive medical supplies, laboratory materials, blood products, vaccines, or other controlled-load items. These applications can require more than basic cooling, including stable temperature control, clear monitoring, service access, and reliable power management. I therefore treat the CITIMAX 350 as part of a complete vehicle refrigeration system rather than as an isolated component.
Buyers should request a technical datasheet or nameplate image for the exact unit being offered. A professional specification review should identify the nominal cooling capacity, rated voltage, power demand, refrigerant type, evaporator and condenser arrangement, control method, noise information where available, dimensions, weight, and recommended cargo-body application. If any of these details are unavailable, the supplier should clearly mark them as pending confirmation rather than making an assumption.
| Specification Area | What to Confirm | Why It Matters |
|---|---|---|
| Electrical system | Vehicle voltage in V, current demand in A, alternator and battery requirements | Prevents overload, starting problems, and incompatible installation |
| Cooling performance | Capacity under stated ambient and cargo conditions, commonly expressed in W or BTU/h | Shows whether the unit can support the actual insulated body |
| Temperature control | Target range in °C, controller functions, alarms, and sensor arrangement | Important for sensitive emergency and medical cargo |
| Physical installation | Unit dimensions in mm, mounting pattern, clearances, service access, and airflow path | Determines whether the vehicle can accept the equipment safely |
| Refrigerant and service | Refrigerant designation, charging procedure, spare parts, and maintenance requirements | Supports compliant servicing and long-term availability |
As a practical purchasing record, I suggest documenting at least three measured data points for every vehicle: the cargo-body length in m, the required setpoint in °C, and the available electrical supply in V. These values do not replace the manufacturer’s performance data, but they give the supplier enough information to begin a responsible compatibility review. For example, a 24 V vehicle system should not be assumed to accept a unit designed for another electrical architecture without written confirmation.
Compatibility begins with the vehicle chassis and electrical system. The installer should check whether the alternator, battery, wiring, fuse protection, and control interface can support the refrigeration unit under normal operating conditions. The mounting location must also provide adequate structural support, condenser airflow, protection from impact, and access for inspection and repair.
For emergency vehicles, available roof, sidewall, or underbody space may already be occupied by medical equipment, warning systems, storage modules, or auxiliary power components. I recommend confirming the installation envelope in millimetres and reviewing cable routing before finalizing the body design. A unit that fits dimensionally may still be unsuitable if airflow is restricted or routine service cannot be performed.
The refrigeration requirement is influenced by the cargo-body volume, insulation thickness, door seal condition, floor construction, solar exposure, and frequency of door opening. A unit selected for a well-insulated body may not provide the same practical result in an older body with damaged seals or high heat infiltration. The supplier should assess the complete thermal load, especially when the vehicle operates in hot climates or remains stationary for extended periods.
Load type also affects selection. Chilled medical products, frozen materials, general food cargo, and mixed emergency supplies may require different temperature strategies and monitoring arrangements. Buyers should provide the expected product temperature, loading temperature, loading pattern, trip duration, and acceptable temperature deviation instead of describing the requirement only as “cold transport.”
Start with the unit nameplate, product code, serial number, and available technical literature. Request photographs of the identification plate and major components if the equipment is being sourced through a distributor or used-vehicle channel. This step helps distinguish between similar designations and reduces the risk of comparing different configurations under one model name.

Record the vehicle type, insulated-body dimensions, cargo volume, operating region, expected ambient temperature, and target cargo temperature. For emergency vehicles, also describe whether the system must operate while driving, during stationary periods, or through an auxiliary power source. These details allow the supplier to evaluate both cooling demand and power availability.
Ask for dimensional drawings, mounting requirements, electrical diagrams, airflow clearances, controller location, drain arrangements, and service access recommendations. The installer should check the condenser and evaporator positions before bodywork is completed. Early coordination is usually more efficient than modifying a finished vehicle after discovering a clearance or cable-routing problem.
Procurement should cover more than the initial unit price. Confirm warranty terms, spare-parts availability, technical documentation, commissioning responsibility, troubleshooting support, and the expected lead time for replacement components. If the vehicle operates across borders, also verify whether local technicians can service the stated refrigerant and control system.
The most common mistake is treating the model number as proof of cooling capacity. A second mistake is selecting a unit without checking the cargo-body insulation, door-opening pattern, and ambient operating conditions. These omissions can produce a system that appears suitable on paper but struggles to maintain the required temperature in real service.
Another avoidable error is confirming only the voltage while ignoring current demand, alternator capacity, battery condition, and auxiliary power arrangements. Buyers may also overlook controller placement, alarm visibility, data recording, and access to service components. For temperature-sensitive emergency loads, these operational details can be as important as the refrigeration hardware itself.
The final price of a CITIMAX 350 refrigeration solution may depend on the unit configuration, mounting components, controller, installation materials, shipping terms, spare parts, and commissioning requirements. A like-for-like comparison should separate the refrigeration unit from optional accessories and vehicle integration work. I recommend asking suppliers to state what is included, excluded, and still subject to technical confirmation.
Minimum order quantity and lead time can vary according to stock status, configuration, export destination, and customization. Instead of relying on a general delivery statement, request a written quotation that identifies the selected version, quantity, packing method, commercial terms, and estimated dispatch schedule. If the project has a fixed vehicle-production date, communicate that milestone before the order is confirmed.
ACOOLER supports B2B buyers by reviewing application information, organizing product specifications, and coordinating a quotation for CITIMAX 350 refrigeration requirements. Our approach is to collect the vehicle voltage, body dimensions, target temperature, operating environment, installation position, and quantity before recommending a sourcing path. Where information is incomplete, we identify the missing items for confirmation instead of presenting uncertain data as a guaranteed specification.
We can also help buyers prepare a technical inquiry for an emergency vehicle project, compare configuration requirements, and coordinate questions concerning packaging, documentation, spare parts, and delivery. The exact scope of support depends on the project and supplier arrangement. This process is designed to help fleet managers, vehicle builders, distributors, and export buyers make a clearer purchasing decision.
The right CITIMAX 350 refrigeration unit is the version that matches the vehicle’s electrical system, physical installation space, insulated cargo body, temperature requirement, and service environment. Do not approve the purchase from the model name alone; first verify the complete identification, cooling data, dimensions, refrigerant, controls, and installation requirements. This is particularly important for emergency vehicles carrying medical or temperature-sensitive materials.
Your next step should be to prepare the vehicle and cargo specification sheet, collect the unit nameplate or model documentation, and request a written compatibility review. Send those details to ACOOLER for quotation preparation and supplier coordination. With the application clearly defined, you can compare offers on verified performance, installation fit, service support, and total procurement risk rather than on unit price alone.
