KOLDVOLT Mini Refrigerated Trailer Real-World Data Test Case
For businesses engaged in refrigerated transportation, the stability of equipment performance directly determines the rate of cargo loss, operational costs, and investment returns. This article will take you through the actual test data of KOLDVOLT 7X12 feet commercial freezer/Cooler Trailer applied in a North American fresh food distribution company, and interpret the core competitiveness of this small refrigerated trailer from the dimensions of cooling efficiency, thermal insulation performance, adaptability, and cost-effectiveness.
Project Background: The Pain Points of Fresh Food Distribution Enterprises in Cold Chain Transportation
The client is a medium-sized fresh food distribution enterprise located in California, USA, mainly engaged in the door-to-door delivery of fruits, vegetables, and frozen meat. Before cooperating with KOLDVOLT, the enterprise has been troubled by the following pain points:
Slow cooling speed: The traditional small refrigerated trailer takes an average of 45 minutes to cool from room temperature (25℃) to -20℃, which seriously delays the delivery time and leads to a 12% cargo loss rate during peak periods.
1.Poor thermal insulation performance: In the case of sudden power failure, the temperature in the compartment rises by 5℃ within 8 hours, which fails to meet the fresh-keeping requirements of frozen goods and does not comply with the relevant provisions of the latest version of the cold chain transportation standard.
2.Low adaptability: It cannot be flexibly matched with pickup trucks, vans, and other common transport vehicles. It is easy to have vibration and equipment failure when driving on non-paved roads.
3.High maintenance cost: The integrated refrigeration unit requires professional personnel to disassemble and maintain, and the average downtime is as long as 3 days each time, which seriously affects the distribution efficiency.
4.After comparing the products of 5 well-known brands in the global market, the enterprise finally chose KOLDVOLT 7X12 feet commercial freezer/cooler trailer, which is famous for its Plug2Go Reefer technology, heavy-duty structure, and customizable solutions. Next, we will present the test results of this equipment in actual operation.

Real Data Test: Four Core Dimensions to Verify the Performance of KOLDVOLT Small Refrigerated Trailer
1. Cooling Efficiency Test: 30 Minutes to Reach -20℃, Leading the Industry StandardTest conditions: Ambient temperature 25℃, compartment load rate 70% (simulating the actual distribution state), using the standard refrigeration mode of the equipment. Test object: KOLDVOLT 7X12 feet commercial freezer/cooler trailer VS industry average level of small Refrigerated Trailers.
Test data comparison:
The core reason why KOLDVOLT small refrigerated trailer can achieve efficient cooling is its 4-inch PU foam insulation panel with 2mm FRP skins and high-power battery-driven Plug2Go Reefer Unit. The lightweight design of the equipment does not increase the load of the transport vehicle, while the cooling capacity is 20% higher than that of products of the same volume on the market.
2. Thermal Insulation Performance Test: Comply with GB/T 34399-2025 Standard, Ensure Cargo Safety
For cold chain transportation equipment, thermal insulation performance is as important as cooling efficiency, especially in the case of sudden power failure or long-term parking. This test refers to the requirements of the national standard GB/T 34399-2025 “Technical Specifications for Performance Confirmation of Temperature Control Facilities and Equipment Verification in Pharmaceutical Product Cold Chain Logistics” and simulates the extreme working condition of sudden power failure during transportation.
Test conditions: The compartment temperature is stabilized at -20℃, then the power is cut off, and the ambient temperature is 30℃.Test results: Within 8 hours of power failure, the temperature in the compartment of KOLDVOLT small refrigerated trailer only rises by 3℃, which is far lower than the industry average of 5℃ and fully meets the standard requirements of temperature rise not exceeding 5℃ within 8 hours.
The excellent thermal insulation performance comes from the seamless sealing design of the equipment and the high-density PU insulation material. This performance means that even in remote areas with unstable power supply, the KOLDVOLT small refrigerated trailer can ensure the quality and safety of fresh and frozen goods.
3. Adaptability & Durability Test: Compatible with Multiple Vehicles, Adapt to Harsh Road Conditions
KOLDVOLT small refrigerated trailer is designed with the concept of flexible application for van, pickup, truck, trailer, tricycle, which can be quickly connected and disassembled with different transport vehicles. The following is the test data of the equipment in actual road conditions:
Vehicle compatibility test: It takes only 15 minutes to complete the installation and commissioning on Ford F-150 pickup truck and Mercedes-Benz Sprinter van, and the connection stability rate is 100% during the test period.
Harsh road durability test: The equipment runs continuously for 1000km on gravel roads and mountain roads with large slopes. The heavy-duty structure design effectively reduces the vibration of the compartment. After the test, the refrigeration unit and insulation panel are intact, and the temperature control performance is not affected.
Maintenance convenience test: Thanks to the interchangeable reefer unit design, when the equipment needs maintenance, the damaged unit can be replaced within 1 hour, and the downtime is reduced by 60% compared with the traditional integrated unit. The enterprise’s maintenance cost per month is reduced from $800 to $300.
4. Cost-Effectiveness Test: Reduce Cargo Loss Rate by 70%, Shorten ROI Cycle to 6 Months
For logistics enterprises, the ultimate test of equipment performance is the reduction of operational costs and the improvement of investment returns. According to the operation data of the North American fresh food distribution enterprise in the past 6 months:The cargo loss rate has dropped from the original 12% to 3.5%, a decrease of 70%.
The monthly distribution efficiency has increased by 40%, and the number of single-vehicle delivery outlets has increased from 12 to 19.The comprehensive operation cost has decreased by 28%, including fuel cost, maintenance cost, and cargo loss compensation cost.
The investment return cycle (ROI) is only 6 months, which is shorter than the industry average of 8 months.Customer Feedback: KOLDVOLT Small Refrigerated Trailer is the Core Asset of Cold Chain Transportation
