Why a Parking Air Conditioner Is Essential for Trucking Fleets
Modern logistics increasingly rely on driver well-being and fuel efficiency. Traditional idling for air conditioning not only consumes fuel but also increases engine wear and emissions. A 24V parking air conditioner offers a silent, energy-saving alternative that keeps the cab cool while the engine is off—improving driver satisfaction and reducing operational costs.
What to Look for in a Parking Air Conditioner
When selecting a system for your fleet, consider:
①Cooling capacity: Can it handle extreme heat in various climates?
②Power efficiency: Is it optimized for 24V commercial vehicle systems?
③Durability: Can it endure long-term vibration, dust, and usage?
④Installation: Is it compatible with your truck models?
⑤After-sales support: Will you get reliable service and parts?

A familiar picture in parking areas: truck drivers leaving the engine running for hours to use the air conditioner or to recharge the batteries during their resting periods. This is bad for the environment, and it’s also against the law. Tons of fuel are wasted, and fleet operators pay dearly for it, plus the wear and tear on the engine. A parking cooler keeps operating costs down. Equally important to fleet owners is the fact that it improves work safety and thus ensures that the driver and freight arrive safe and sound.
The air temperature felt by the human body may differ from the actual, measured air temperature. Our thermal sensation ranges from warm or hot through comfortable to cold. We all want to enjoy a comfortable climate, and humidity plays a decisive role. When humidity is low, we tolerate even hot air temperatures even though we sweat. Dry heat makes the sweat evaporate quickly from the skin and creates a cooling effect. This won’t happen, though, in a warm humid climate, when humidity is high transpiration diminishes and with it the cooling effect. As a result, we feel the heat even more. The air feels damp and sticky, which may lead to circulatory troubles and insomnia.
Knowing all this, it becomes obvious what a good truck parking cooler ought to do. Cooling alone is not enough; it’s also necessary to reduce the humidity to get a comfortable climate.
OUR TIP: COMPRESSOR PARKING COOLERS
Compressor-powered parking coolers are the most effective ones. Unlike condenser-operator systems they also reduce the air humidity.
CoolAir compressor parking coolers have been around for over ten years to improve working conditions, safety and cost efficiency in the European utility vehicle industry. Powerful and efficient like no other, they offer unique benefits for drivers, installers and fleet operators. Vehicle-specific mounting accessories available for all common truck models make for fast and easy installation with perfect results.
The current Dometic CoolAir range includes three self-contained roof top air conditioners integrating all components in a compact housing and a modular split system for tricky installation conditions, such as cabins with spoilers. This buying guide is meant to help you find the right CoolAir model to suit your truck, your working conditions and your idea of a perfect cabin climate.
Relaxed drivers are safer drivers who are less likely to be involved in accidents. This is one of the reasons why the laws on resting periods for truck drivers are so strict. But what are the conditions drivers need to rest in complete comfort? The temperature range we perceive as comfortable is not really that wide, as the illustration above shows. Temperatures up to 26 °C are only felt as pleasant when humidity is low. When the air is damp, the thermometer should not exceed 20 °C. We feel more comfortable when the room temperature is between 18 °C and 22 °C and the humidity between 40 and 70 %. To create these conditions in a truck cabin the air must be cooled down and dehumidified at the same time. This calls for a compressor powered air conditioner. A/C systems based on direct or indirect evaporation cooling are less effective.
The two CoolAir RTX systems give drivers a choice of four operating modes to make it even easier for them to adjust the cooling capacity to individual climate conditions and personal comfort requirements.Automatic mode: Fan and compressor are controlled automatically.
Eco mode: The compressor speed is limited to a maximum of revs/min (instead of revs/min). This saves energy and extends the runtime.
Boost mode: Compressor and fan are running at full capacity – for a maximum of 20 minutes, or until the preset temperature has been reached. Then the system switches back to automatic mode.
Manual mode: The blower speed can be set to five different levels.
PERFORMANCE TESTS CONFIRM BEST RATINGS FOR RTX
CoolAir RTX parking coolers keep it nice and cool, even in soaring heat. CoolAir RTX lives up to its promise even at outside temperatures of 52 °C.
At the end of May 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 – were subjected to real-life conditions for about twelve hours. We are very pleased to let you know that our CoolAir RTX was the test winner in all categories. It even performed better than stipulated in our catalogues.
The engines of trucks fitted with a parking cooler require less maintenance. This is simply because drivers are less likely to have them run idle to operate the A/C system in their resting periods. The longer service intervals reduce the maintenance costs for fleet operators. Speaking of maintenance costs ... self-contained CoolAir air conditioners are virtually maintenance-free. All components are integrated in a compact housing. The A/C circuit is closed and hermetically tight. No need to fill up with refrigerant.
The Dometic CoolAir RT 780 rooftop parking cooler is designed for day trips and inner-city distribution services. It gives drivers a pleasant climate during shorter stops and unavoidable waiting periods, e.g. when loading and unloading. As a self-contained air conditioner, the CoolAir RT 780 integrates all components in a single housing. Installation is quickly done, and there’s no need for maintenance either. Good to know: the CoolAir RT 780 fits almost every truck. It comes in two versions, with 0° or 12° compressor tilt, to accommodate different roof designs. Tailor-made installation kits are available for all common truck models.
During the installation of the SP 950C compressor unit existing fastening points are used. In our case the mounting holes and bolts on the outside rear of the cabin. The fastening frame for the compressor unit perfectly matches the fastening pattern of the respective vehicle. Besides time savings the CoolAir installation concepts offers two other convincing advantages. The installation result is impeccable, inside and out, like with an original fitting. After removal the CoolAir leaves no mark. No laborious refinishing, no money lost when the vehicle is sold!
