Truck Parking Cool Box Buying Guide

At the end of May 2017 a leading East European transport company tested truck parking coolers of four major brands to support the decision-making for a future investment. During the two-day test run, all candidates – including the CoolAir RTX 1000 – were subjected to real-life conditions for about twelve hours. We are very pleased to let you know that our CoolAir RTX 1000 was the test winner in all categories. It even performed better than stipulated in our catalogues.

TEST CONDITIONS

• Two three-year-old trucks as testbeds (DAF XF and MB Actros)
• Trucks parked on asphalt and subjected to direct sunlight
• Cabin temperature set to 22 °C
• Battery guard operated at factory default setting
• Day 1: switch-on at 11:15; factory-new battery package; without using the sun shades/curtains
• Day 2: switch-on at 09:30; used but freshly charged battery package; with the sun shades/curtains closed

Test results for CoolAir RTX 1000

To cut a long story short, our parking cooler hit all records in the test!

• RTX showed the quickest cool-down in both cabs/on both days.
• RTX was the only unit to reach the setpoint (22 °C) in both cabs (both days)
• RTX was the only unit to keep the lower bed temperature at a comfortable “resting level” through the entire runtime.
• RTX provided the longest runtime while maintaining the required temperature.
• RTX had the highest battery readings at any given moment of the test – i.e. the lowest energy consumption.

Superior energy efficiency

CoolAir RTX parking coolers feature a variable speed inverter compressor, which allows for excellent cooling, amazingly quiet operation and superior energy efficiency. Moreover, our latest generation parking coolers are fitted with a smart refrigerant injection technology to make more economical use of refrigerant. While other manufacturers use a rather “static” capillary tubing system, the inventors of the CoolAir RTX opted for an adaptive, thermostat controlled expansion valve. The expansion valve ensures that the evaporator always gets the right amount of refrigerant – no more and no less than required to achieve the desired temperature in the driver’s cab. Quite similar to the automatic transmission of a car, the CoolAir RTX refrigerant injection system automatically adapts to the performance requirements. Capillary systems, by contrast, always inject the same amount of refrigerant. Using the same metaphor, they are like an engine running full throttle all the time.

ADR-compliant for dangerous goods transport>

The European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR for short) contains special provisions as to the security of load, the marking of dangerous goods and the equipment of vehicles participating in road transport. The two CoolAir RTX parking coolers and our CoolAir SP 950 split system are ADR-compliant. That means they can be installed and operated with no further refitting and no special entry in the vehicle documents required.
