CITIMAX 350 Specifications and Procurement Guide

The CITIMAX 350 should be evaluated as a complete truck refrigeration solution, not by model name alone. Before I approve a purchase, I confirm the exact cooling-capacity rating, operating-temperature range, power configuration, installation requirements, and after-sales support included in the quotation. Because specifications can vary by production version, vehicle application, and market configuration, I recommend requesting the current technical datasheet and a model-specific quotation from the supplier. This guide explains how I assess the CITIMAX 350 and how buyers can reduce specification, compatibility, and sourcing risks.

Who This Guide Is For

I prepared this guide for fleet owners, refrigerated transport operators, truck body builders, distributors, importers, and procurement teams comparing refrigeration units for commercial vehicles. It is particularly useful when the buyer has identified the CITIMAX 350 but still needs to confirm whether the unit matches the truck, cargo body, route, and temperature requirements. It can also support distributors who need consistent information before placing an OEM or replacement-unit order.

The guide is not a substitute for the manufacturer’s current datasheet or an installation inspection. Instead, I use it as a practical framework for organizing questions, comparing quotations, and identifying missing information. This approach is important because refrigeration performance depends on more than the nominal model designation.

What the CITIMAX 350 Is Designed to Do

The CITIMAX 350 is a truck refrigeration unit intended to help maintain the required cargo temperature during transportation. Its value depends on its ability to remove heat from the cargo compartment under the actual operating conditions, including ambient temperature, door openings, insulation quality, cargo loading, and delivery-route duration. The refrigeration unit is therefore one part of a wider temperature-control system.

In procurement discussions, I separate three functions: cooling performance, temperature maintenance, and vehicle integration. Cooling performance concerns how much heat the system can remove; temperature maintenance concerns stability during transport; and integration covers mounting, power transmission, controls, drainage, service access, and compatibility with the truck body. A supplier should explain these points in relation to the buyer’s specific vehicle rather than relying only on a general brochure description.

Key Specification Areas to Confirm

Cooling Capacity and Temperature Range

The first question I ask is how the stated capacity was measured. A refrigeration rating without test conditions can be difficult to compare because capacity changes with ambient temperature, evaporator conditions, engine speed, and the target cargo temperature. I request the capacity data at the operating conditions relevant to my route, and I ask whether the unit is intended for chilled cargo, frozen cargo, or another temperature-controlled application.

Do not assume that the “350” in CITIMAX 350 automatically identifies a universal cooling-capacity value. I treat the model name as an identification reference until the supplier confirms the applicable performance data. For example, the RFQ should state a target cargo range such as 0°C to 5°C for chilled goods or a lower range if frozen transport is required; this temperature range is a buyer requirement, not an unverified claim about the unit.

Power and Vehicle Compatibility

I also confirm how the CITIMAX 350 receives power and how it interfaces with the vehicle. Depending on the configuration, a truck refrigeration unit may use an engine-driven, direct-drive, electric, or hybrid arrangement, so the supplier must identify the exact configuration being offered. The quotation should specify the required electrical voltage, mounting arrangement, belt or drive requirements where applicable, and any vehicle-side components needed for installation.

For procurement control, I ask the supplier to list the vehicle make, model, engine type, body dimensions, and available mounting space in the quotation. I also request confirmation of the control-panel location, wiring requirements, and access needed for routine maintenance. A nominal 24 V vehicle electrical system, for example, should never be assumed to be compatible without checking the actual unit configuration and vehicle wiring.

Evaporator, Condenser, and Body Configuration

The evaporator and condenser arrangement must match the refrigerated body and the available installation space. I check whether the proposed configuration is suitable for the body length, internal volume, insulation thickness, door design, and airflow pattern. If the evaporator is too large for the compartment or poorly positioned, it may create installation problems even when the refrigeration unit itself is technically suitable.

I also ask whether the unit is intended for a single-temperature body or a more specialized configuration. A single-compartment truck generally has a simpler selection process, while multi-temperature transport may require separate control zones or additional equipment. The supplier should clearly state what is included, what is optional, and what must be supplied by the truck body builder.

Matching the CITIMAX 350 to the Application

I match the unit to the cargo and operating pattern before comparing price. Fresh food, dairy products, pharmaceuticals, flowers, and frozen goods can have different temperature-control requirements, and frequent door opening creates a different heat load from long-haul transport with minimal stops. The buyer should provide the cargo type, target temperature, body volume, expected ambient conditions, route length, and delivery frequency.

For urban distribution, I give special attention to door-opening recovery, control accessibility, noise expectations, and service convenience. For regional or long-distance transport, I focus more heavily on continuous operating capability, fuel or energy consumption, component durability, and parts availability. If the truck operates in a hot climate, I ask for performance information at the expected ambient condition rather than relying on a mild-climate rating.

A Practical Selection Framework

1. Define the cargo requirement: Record the target temperature, allowable variation, cargo sensitivity, and whether the unit must cool pre-loaded cargo or only maintain an existing temperature.
2. Measure the vehicle and body: Provide body length, width, height, insulation details, door count, mounting location, and available service clearance.
3. Confirm the operating profile: State daily operating hours, route type, ambient climate, stop frequency, and expected door openings.
4. Request model-specific data: Ask for capacity, operating range, power requirements, dimensions, weight, controls, and installation instructions for the quoted CITIMAX 350 configuration.
5. Compare the complete offer: Include the unit, mounting hardware, controls, installation, commissioning, spare parts, warranty terms, packaging, and export documentation.
6. Approve only after compatibility review: Have the vehicle or body builder verify the installation before placing the final order.

I use this process because the lowest unit price does not always represent the lowest procurement cost. An incomplete quotation can create additional expenses for brackets, wiring, controls, installation labor, replacement parts, or shipping corrections. A written scope makes supplier quotations easier to compare and reduces ambiguity between the buyer, exporter, installer, and end user.

Pricing, MOQ, and Lead-Time Questions

Pricing for the CITIMAX 350 should be requested according to the exact configuration and commercial terms. I ask whether the price is for the refrigeration unit only or includes installation accessories, control components, manuals, and commissioning support. I also confirm the quotation currency, Incoterm, packaging method, payment schedule, warranty coverage, and validity period.

Minimum order quantity can vary by configuration, stock position, and whether the buyer requires private labeling or customized packaging. For a trial order, I ask whether one unit is available for vehicle verification before a larger purchase. I also request a written production or dispatch schedule and separate the estimated manufacturing time from international transit time.

For planning purposes, I recommend requesting at least 12 months of recommended spare-parts availability or service-planning information, if the supplier can provide it. This does not represent a guaranteed product lifespan; it is a procurement checkpoint that helps the buyer plan filters, belts, electrical items, controls, and other service components. The supplier should identify which parts are routine consumables and which require technical diagnosis.

Supplier Evaluation Checklist

Technical Documentation

I evaluate whether the supplier can provide a current datasheet, installation drawing, wiring information, operating instructions, maintenance guidance, and spare-parts identification. The documents should correspond to the quoted CITIMAX 350 version rather than a similar-looking model. If the supplier cannot explain a specification or provide a clear configuration list, I treat that as a reason to pause the purchase.

Installation and Service Support

A reliable supplier should explain the installation boundary clearly. I ask whether ACOOLER is supplying the unit, accessories, installation guidance, replacement parts, or technical coordination, and I confirm which tasks remain with the local installer. This division of responsibility is especially important when the refrigeration unit is exported to a market where vehicle models and service practices differ.

At ACOOLER, I can support buyers by organizing the required vehicle and cargo information, confirming the available CITIMAX 350 configuration, preparing a structured quotation, and coordinating documentation for review. Where the application requires further confirmation, I recommend a technical check before commercial approval rather than making an unsupported performance promise. This approach helps distributors and fleet operators make decisions based on documented requirements.

Common Procurement Mistakes

• Choosing by model name alone: The model designation does not replace confirmation of capacity, temperature range, and configuration.
• Ignoring body insulation: Poor insulation or damaged door seals can increase the refrigeration load and reduce temperature stability.
• Comparing incomplete quotations: A low equipment price may exclude controls, mounting parts, installation, or export packaging.
• Failing to check local service capability: The buyer should know who will install, diagnose, and repair the unit after delivery.
• Ordering before vehicle confirmation: Mounting space, power supply, and body dimensions must be checked before final approval.

Procurement Summary

The CITIMAX 350 can be a suitable truck refrigeration option when its documented configuration matches the cargo temperature, vehicle platform, refrigerated-body dimensions, and operating environment. My recommendation is to verify the technical datasheet, request model-specific performance information, and compare the complete delivered solution rather than the unit price alone. Buyers should also confirm installation responsibility, spare-parts support, warranty terms, and expected lead time in writing.

The next step is to prepare an RFQ containing the vehicle model, body dimensions, cargo type, required temperature, route conditions, power information, quantity, destination, and preferred delivery schedule. Send these details to ACOOLER for a configuration review and commercial quotation. With a complete requirement sheet, I can help identify the relevant CITIMAX 350 specification, clarify included components, and structure the procurement process for a more predictable purchase.
