Sun CO2 R744 aircoservicestation
More and more vehicles are being equipped with CO2 air conditioning systems. Snap-on Tools is a supplier of the ECO2KARE, an air conditioning service station for a wide variety of mobile air conditioning systems using CO2 / R744 refrigerant.
Unique characteristics (benchmarked)
The most powerful (two-stage) vacuum pump for light- and heavy-duty vehicles evacuates all refrigerant, including harmful moisture.
Large from a distance and clearly visible in direct sunlight 7-inch touchscreen (other screens are smaller)
Heating system with manual adjustment option for tank heating speeds up the filling process and saves time
Pressure test forming gas standard built-in (optional on other brands)
3-metre-long service hoses (50 cm longer than other brands)
The Sun ECO2KARE is one of the first CO2 R744 air conditioning service stations available. The station distinguishes itself from other brands in a number of important areas. For example, the machine has the most powerful (two-stage) vacuum pump available. With this pump, Sun guarantees that all refrigerant, including harmful moisture, is completely recovered from the air conditioning system.
In addition, the powerful pump makes the machine suitable for servicing heavy-duty air conditioning systems in passenger cars (M1), vans (N1), lorries (trucks) (N2, N3), buses (M2, M3), agricultural and forestry vehicles (T-class) and trains, among others.
Air conditioning systems that use CO2 (R744) refrigerant require maintenance [read the article about this], especially in plug-in hybrid (PHEV) and electric (BEV) vehicles. This is because the air conditioning also manages the temperature of battery packs and related expensive components. In the video below from trade magazine AMT, Dennis de Nieuwe from Snap-on demonstrates how to do this with the SUN ECO2KARE air conditioning machine and a Skoda Enyaq EV.
Standard richly equipped
Another unique feature is the large 7-inch touchscreen, which is easy to read even in direct sunlight. A built-in heating system with manual adjustment to heat the refrigerant tank speeds up the filling process and saves a lot of time compared to other air conditioning service stations.
Sun supplies the ECO2KARE as standard with a forming gas pressure tester, which has to be purchased separately as an option for other machines. The three-metre hoses supplied as standard make it possible to carry out other work on a vehicle during air conditioning service on the bridge. Although the Sun ECO2KARE comes standard with many features that are optional on other machines, its price is very competitive.
Features Sun ECO2KARE CO2 / R744 air conditioning service station
Robust, Powerful and Safe
Simple, fast and highly intuitive menu operation on a 7" touchscreen with Linux operating system
Status light
Easy replacement of R744 tanks of different sizes, protective cover and fastening with safety belt
Possible refrigerant bottles: the gross weight of up to 50 kg allows the use of standard commercial sizes for refrigerant quantities of 1 to 22.6 kg, a height of 35 cm to 120 cm including connections, and a diameter of 10 cm to 21 cm.
Menu operation is very simple with images, icons, short texts and the virtual keyboard.
Completely safe: software-guided processes include all necessary control instructions and constant monitoring of the CO2 concentration in the atmosphere.
Integrated hybrid function for flushing service hoses and internal circuits. Indispensable for safe maintenance of systems with an electric compressor.
The very powerful 142 l/min two-stage vacuum pump also makes the station suitable for large systems (trains, buses) and guarantees a highly efficient vacuum phase for drying the system, which is particularly important for CO2 systems.
Heating system with manual setting option for longer heating speeds up the filling process and helps save time
Management of three high-quality, hermetically sealed, refillable containers for compressor oil (1x PAG and 1x POE) and dye (included)
Automatic pressure test with nitrogen or hydrogen/nitrogen mixture
3-metre-long service hoses for efficient connection to the vehicle so that the car can be raised when it is on the bridge and the mechanic can do other work while servicing the air conditioning.
Large pressure gauges, clearly visible even from a distance, 100 mm.
Connection to the cylinder: hose 1 m, RAC8164 adapter W21, 7×1/14'' – ¼ SAE male, RAC8165 adapter W21, 8×1/14'' – ¼ SAE male.
Quick plug-in connection for CO2 discharge hose (PA12 8×10 mm, TUB1259)
Efficient internal ventilation to prevent internal components from freezing
Online vehicle database updates via USB interface or directly via Wi-Fi connection
Spacious storage compartment for accessories
Easy to maintain
Robust housing for optimum protection of the station
Efficient and cost-effective thanks to low maintenance and minimal use of consumables
Environmentally friendly packaging made from wood and paper without the use of polystyrene
