CITIMAX 350 Refrigeration Unit Specifications and Buying Guide

The CITIMAX 350 is a vehicle refrigeration unit intended for temperature-controlled transport, but its exact specifications depend on the vehicle installation, power configuration, operating environment, and the supplier’s current product documentation. I recommend treating the official model datasheet, installation manual, and quotation as the controlling sources for cooling capacity, dimensions, refrigerant, electrical requirements, and warranty terms. In this guide, I explain how I evaluate a CITIMAX 350 purchase, which specifications matter most, where the unit may fit, and what information buyers should request before placing an order.

For a reliable decision, I would not select the unit by model name alone. I first match the required temperature range, cargo-body volume, door-opening frequency, ambient conditions, power source, and service location. Food and pharmaceutical applications should also be evaluated against applicable handling rules, including the U.S. Food and Drug Administration’s sanitary transportation requirements under 21 CFR Part 1, Subpart O.

Who This Guide Is For

This guide is for fleet operators, truck body builders, food distributors, cold-chain logistics companies, vehicle dealers, and procurement teams comparing transport refrigeration equipment. It is also useful for buyers sourcing CITIMAX 350 units through an export supplier or requesting a replacement, retrofit, or complete vehicle refrigeration solution. I focus on practical purchasing questions rather than presenting unverified model data as confirmed specifications.

The guide is especially relevant when a buyer needs temperature control for chilled or frozen products. Before requesting a quotation, I suggest preparing the vehicle type, body dimensions, insulation details, target temperature, daily operating hours, and delivery destination. These details allow a supplier to confirm whether the CITIMAX 350 configuration is appropriate instead of quoting a unit that may be undersized or incorrectly equipped.

What the CITIMAX 350 Specification Should Cover

A complete specification should include more than the nominal model designation. I normally divide the evaluation into refrigeration performance, vehicle compatibility, electrical or mechanical power, installation requirements, controls, maintenance, and commercial terms. If any of these items are missing from the quotation, I request written clarification before comparing prices.

Refrigeration Performance

The most important technical point is the approved cooling capacity at stated test conditions. Cooling capacity should be reported with a temperature condition, such as a specified evaporator temperature and ambient temperature, because a value without test conditions is difficult to compare. I also ask whether the quoted capacity is intended for maintaining pre-cooled cargo or for pulling down warm cargo, since these are different operating demands.

For application planning, buyers should identify the intended cargo range. A chilled distribution route may require approximately 2–8°C, while frozen food logistics may require temperatures around -18°C or below, depending on the product and applicable handling rules. These ranges are application examples, not a confirmation that every CITIMAX 350 configuration can achieve them; the supplier must confirm the operating envelope in writing.

Vehicle and Installation Compatibility

Request the unit’s overall length, width, height, mounting pattern, weight, condenser clearance, evaporator dimensions, and required service access. The vehicle body should also be checked for insulation thickness, internal volume, door configuration, floor construction, and airflow restrictions. A refrigeration unit that fits the truck externally may still perform poorly if the body insulation or air distribution is unsuitable.

I also confirm whether the installation is designed for a van, light truck, medium truck, or another vehicle category. Vehicle payload is a measurable consideration: if the complete system adds 100 kg, for example, that weight should be included in the legal and commercial payload calculation. The final installation should be reviewed by a qualified technician because incorrect mounting, wiring, refrigerant work, or airflow clearance can affect safety and performance.

Power and Control Requirements

The quotation should identify whether the CITIMAX 350 uses direct vehicle power, an engine-driven compressor, a dedicated electrical system, standby power, or another configuration. Electrical details should include nominal voltage, current demand, fuse or protection requirements, alternator requirements, and battery implications. A 12 V system and a 24 V system are not interchangeable without confirming the correct configuration and installation components.

For multi-stop delivery, I ask whether the controller supports set-point adjustment, alarm indication, temperature display, fault codes, and data recording. If remote monitoring is required, I request confirmation of the communication hardware, network availability, subscription cost, and data ownership. These features should be listed as included, optional, or unavailable rather than assumed from the model name.

Application Matching: When the CITIMAX 350 May Fit

The CITIMAX 350 may be considered for refrigerated distribution vehicles where the required cooling performance, body volume, and power arrangement match the approved configuration. Typical use cases can include fresh food delivery, dairy distribution, meat transport, frozen-food routes, floral logistics, and other temperature-sensitive cargo. Suitability depends on heat load, route duration, ambient temperature, loading practice, and the number of door openings.

I pay particular attention to loading conditions. If cargo enters the body at the correct temperature and the doors are opened for short periods, the refrigeration system mainly maintains temperature. If warm cargo is loaded, the vehicle remains in direct sun, or the doors open frequently, the required capacity can be substantially higher than a simple body-volume calculation suggests.

Chilled Distribution

For chilled products, I verify the product temperature requirement, the expected set point, and the acceptable temperature excursion. A buyer may specify a target of 2–8°C for a particular product category, but the product owner’s written handling specification should take priority. The unit, body insulation, loading pattern, and temperature-monitoring process must work together.

With competitive price and timely delivery, ACOOLER sincerely hope to be your supplier and partner.

Frozen Distribution

Frozen transport requires confirmation of the lowest operating temperature and pull-down capability. A buyer should not assume that a unit described as “refrigerated” is automatically suitable for frozen cargo at -18°C. I request a documented operating range, test conditions, defrost method, and recommended body volume for the frozen application.

My CITIMAX 350 Selection Framework

1. Define the cargo requirement: Record the product type, target temperature, allowable variation, loading temperature, and maximum route duration in hours.
2. Measure the vehicle body: Provide internal length, width, height, estimated volume in cubic metres, insulation specification, door count, and door size.
3. Describe the route: State ambient conditions, daily mileage, stop frequency, traffic conditions, parking time, and expected number of door openings.
4. Confirm the power system: Specify vehicle voltage, engine type, available electrical capacity, and whether standby operation is required.
5. Request model documentation: Ask for the current datasheet, installation drawing, wiring diagram, operating manual, parts list, and warranty terms.
6. Compare total cost: Include the unit, mounting kit, installation, commissioning, spare parts, shipping, taxes, technician support, and expected maintenance.

This process prevents a common purchasing error: comparing one supplier’s refrigeration-unit price with another supplier’s complete installed-system price. I recommend asking every supplier to separate equipment cost, installation cost, optional features, freight, and after-sales support. A transparent quotation makes technical and commercial comparisons more reliable.

Key Specifications to Request in a Quotation

The figures in the table are specification categories rather than claimed CITIMAX 350 values. I would only publish or approve exact values after checking the current manufacturer documentation for the intended configuration. This distinction is important because refrigeration performance can change with power source, evaporator choice, ambient temperature, and installation design.

Pricing, MOQ, Lead Time, and Import Considerations

CITIMAX 350 purchasing cost can vary according to configuration, quantity, destination, installation scope, and the availability of genuine replacement parts. Buyers should request pricing for both one complete unit and the expected fleet quantity, because minimum order quantities may differ for units, mounting kits, spare parts, and customized packaging. I also ask whether the quotation is EXW, FOB, CIF, or another trade term so that logistics costs are not misunderstood.

Lead time should be confirmed in calendar days or working days and separated into production, inspection, export preparation, and transit. For example, a supplier should clarify whether a quoted 30-day lead time means dispatch within 30 days or delivery to the buyer’s warehouse within 30 days. Before payment, I verify the product description, serial-number documentation, packing list, invoice, country-of-origin information, and any destination-specific import requirements.

For regulated or pharmaceutical cargo, buyers should also review their own quality procedures and applicable transport rules. The World Health Organization provides guidance for the transport of temperature-sensitive pharmaceutical products, while UNECE ATP establishes requirements for certain international perishable-food transport operations. These sources do not replace product-specific approval or local legal advice, but they are useful references when defining documentation and temperature-control procedures.

Common Buying Mistakes

Choosing by Truck Size Alone

Truck size is only one input in refrigeration selection. Two bodies with the same volume can have different heat loads because of insulation, door design, solar exposure, product temperature, and delivery frequency. I therefore request a basic heat-load review whenever the application involves frozen cargo, high ambient temperatures, or frequent door openings.

Assuming the Model Name Confirms Every Feature

A model designation does not necessarily confirm voltage, evaporator style, standby capability, remote monitoring, or temperature range. Options may differ by market and vehicle platform. I advise buyers to match the exact part number and configuration code shown on the quotation with the serial-number and documentation package supplied with the equipment.

Ignoring After-Sales Support

A refrigeration system is a service-dependent asset, not only a hardware purchase. Before ordering, I check whether the supplier can provide installation instructions, commissioning assistance, troubleshooting guidance, consumable parts, and replacement components. I also ask how technical support is handled across time zones and whether service information is available in English or the buyer’s working language.

How ACOOLER Can Support Your Purchase

At ACOOLER, I can help B2B buyers organize the technical information required for a CITIMAX 350 quotation and coordinate sourcing for emergency vehicles, commercial vehicles, and temperature-controlled transport projects. Our support can include configuration clarification, product documentation collection, vehicle application review, export packing coordination, spare-parts discussion, and communication with the relevant technical team. Exact availability, specifications, warranty coverage, and delivery time should be confirmed for each order.

To receive a useful quotation, send the vehicle model, body dimensions, insulation thickness, required temperature range, cargo type, daily operating hours, destination country, desired quantity, and preferred delivery term. If you are replacing an existing unit, include photographs of the mounting area, power connections, controller, evaporator, and identification plate. With these details, I can help reduce specification gaps and identify the questions that should be answered before purchase.

Summary and Next Steps

The CITIMAX 350 should be selected by verified cooling performance and installation compatibility, not by the model name alone. The most important buying checks are temperature range, cooling capacity under stated conditions, body volume, power supply, dimensions, system weight, controls, maintenance access, documentation, and after-sales support. Exact values must be confirmed against the current manufacturer datasheet and the proposed vehicle configuration.

My recommended next step is to prepare a one-page application brief containing the cargo temperature, body size in cubic metres, vehicle voltage, route duration in hours, ambient conditions, door-opening frequency, and destination. Send that information with your requested quantity and delivery term to ACOOLER for a structured quotation review. This approach gives your procurement team a clearer basis for comparing CITIMAX 350 configurations, installation costs, delivery conditions, and long-term service requirements.
