Aircon system diagnosis requires well experienced service experts. The majority of faults that occur are based on leaks in the pressurised system. We have 3 main methods of finding these leaks.

1. We can use a gas sniffer which can sense the aircon gas when it escapes the system.

2. We can recover the remaining gas and then charge the system with Nitrogen which is a harmless gas that has no impact on the environment. We charge the system with 200psi and use a leak detection fluid which creates bubbles when sprayed on the leaking component to localise the leak.

3. For very slow leaks which are not detectable through the first two methods we can recharge the system with a UV dye which leaks out over time and can easily be seen under a UV light with special glasses. The faulty part can easily be detected by these methods and then be replaced.

On top of leaks there are other faults that can affect your A/C performance. Starting with slipping aircon or fan belts, condenser fans not performing to spec, dirt in condenser, blocked cabin air filter, faulty cabin fan motor, blocked evaporator, fault in electric system to engage compressor clutch, compressor variable load valves, stuck TX valve, etc… We've got the equipment and the experience to check for all of these scenarios and offer you the best possible repair or service option.

We also install aftermarket aircon systems like RedDot units into construction equipment or trucks or we can install your aftermarket reverse cycle aircon units like the full Dometic range into your camper trailer, caravan, motor home, container, slide on camper or whatever else you need to cool down in summer or heat up in winter.

Dual Battery System is what we are passionate about! We have designed and installed numerous dual battery systems specifically tailored to the each customer using state of the art products from Redarc, Victron, Intervolt and EGON. We put your needs in the center of our designs! Each system is tailored to your actual requirements so you end up having exactly what you need for your lifestyle.

Dual Battery systems have become a more and more complex subject over the last 2 decades. With a lot of car manufacturers steering away from constant voltage alternators, the proper charging of a deep cycle battery has become impossible with newer alternators. Car manufacturers have started using temperature compensating and ecu controlled alternators which will lower their voltage output depending on different driving situations.

Temperature compensating alternators will reduce charge voltage with rising temperature of the alternator. After approximately a 20–30 min charge voltage will be reduced to 13.2 volts. At this voltage level a deep cycle battery will not charge properly.

Ecu controlled alternators are even more complex and can stop charge output for short periods of time altogether. This is dependent on different driving situations like heavy accelerating, charge level of the start battery, etc.

This gives us 3 different alternator scenarios. Another issue is the battery that is being used in the setup. Everything else but a standard lead acid deep cycle battery should be charged with a dc/dc charger.

Constant voltage output alternator: A battery isolator (smart isolator relay) system will work well with standard lead acid batteries and a constant voltage output alternator. Every other battery than a standard lead acid (hybrid, deep cycle or start) should not be charged directly with an alternator but always with a dc/dc charger if you want to use the full capacity and lifespan of your battery.

Temperature compensating alternator: A dc/dc charger with voltage sensitive charging on/off setting will work well with this alternator. This setup is also able to charge a wide variety of batteries properly (Lead Acid, AGM, GEL, Lithium). One thing to be careful about in this setup is to choose the right battery for your installation position. For under bonnet mounts, a standard lead acid deep cycle or a Century Dual Force AGM battery are your best options. Fullriver AGM batteries have also been known to last in under bonnet installations but lose their warranty.


It is important to check the manufacturer information on the battery you are using to find out if your battery can cope with the high temperatures that it will have to endure under the bonnet. Bottom line here is that most batteries will last in an under bonnet installation but they will lose their capacity quicker than in an installation where they are not being exposed to high temperatures. Ideally AGM, GEL and Lithium batteries are used inside the cabin, your camper, canopy, etc… these batteries do not gas out like lead acid batteries and don’t necessarily need ventilation. That said in some scenarios (especially for Lithium batteries) you might ventilation to keep the battery temperature e down.

Ecu controlled alternators: A dc/dc charger with ignition trigger works best in this setup. Some manufacturers can disable the “smart” alternator feature, in that case it is best to do so and then use a dc/dc charger with voltage sensing or a battery isolator, depending on your choice of battery. If you can not disable the “smart” feature an ignition triggered dc/dc charger is your only option. Your choice of battery is the same as it is for temperature compensating alternators.

We have Redarc, Intervolt, Enerdrive and EGON charging systems ready and available, and can combine them for you with Century AGM or Standard Lead Acid, Fullriver AGM or Amptron and Enerdrive Lithium batteries to build the dual battery that is right for you.

Finding the right light for your setup wether it be mining, construction, off road driving, overlanding, trucking or camping can be a confusing, time consuming and expensive. You do not always need the most expensive lights available to achieve your desired light output. We will listen to you and supply you with different options in performance and price. All our lights have been tested in previous installations and are always backed up by a local warranty through us and our supplier network, some up to 7 years!

When it comes to lights it is important to understand the different options that are available.

LED lights are a great option for a lot of different reasons. The have a very low current draw and a very high light output compared to a standard halogen globe. They usually come in a very rugged waterproof housing and things like changing a globe are a thing of the past. But they have the same requirements for well-engineered optics to be able to use the light the way you intent to. You can generally choose between very narrow (small angle) beam patterns for long distance lights, broad beam patterns (large angle) for short range and evenly lit areas or a combination of both.

HID lights are great for long distance pencil beam lights. Instead of using a number of lights (like LEDs do) they can focus the full wattage of the light in a single very bright beam and are relatively simple to build great optics. The current draw and light output are a lot better than standard globes. The optics for HID lights are very similar to lights with halogen globes. In a HID light you can have to change the globe but the globes last a lot longer than normal halogen globes.

Halogen globes are very rarely used anymore. Reasons being large current draws for relatively small light output. Globes fail after a while and have to be replaced. These lights still perform well when the wattage of the light is large enough and paired with good optics. The only downsides are maintenance and large current draw. The single most advantage these lights have over HID and LED is the light colour.

Light Colour determines how strongly street signs reflect the light when you are driving. Most LED lights have 6000K (the light colour is measured in Kelvin). 6000K is a very white light that is very close to daylight. It can be tiring on the eyes and reflects from street signs a lot.

On the other hand it will give you very good sight that is close to daylight with a lot of detail. Great for out bush or country driving if the occasional sign does not bother you. The same is true for HID lights.


Most halogen globes have a lower light colour temperature around 5000K (more orange light). This is a lot easier on the eyes and reflects less from road signs. In our opinion you slightly loose detail from the orange light. Recently LED light manufacturers have started to produce lights with lower colour temperature too. This way you can now get all the advantages of LED technology paired with the single most advantage of the old halogen globes.

Beam patterns are very important. For driving lights you generally want a combination of very narrow pencil beams for long distance lighting combined with wide angle work/spread beam lights to give you an evenly lit short range area in front of you. Here a combination of all of the above technologies is possible. For work/camp lights you generally want a low current draw and a very wide beam pattern. That way the light puts least stress on your battery and will give you an evenly lit up work/camp area with almost equal light intensity in the lit up area.

A lot of trust has been lost with solar systems over the years because of poorly designed systems and false promises. Our solar systems are designed with some simple but effective rules. We calculate your average daily power consumption on a worst case scenario. Then we choose the suitable amount of solar power accordingly. To make sure we also keep in mind variables like theoretical power output of a solar panel and real world output of a solar panel (we add 50% solar power). Other variables that will affect your system performance are things like the weather and less than ideal orientation of the panel (for a mobile application a flat mounted panel is still the best option). To overcome these we add another 50% on top. During field tests we have found this design rule, even if it is very crude, to be able to keep your system charged under most conditions.

Another very important building block is the battery capacity. The right battery capacity will vary for most applications. The right battery capacity will depend on how you are using your system and also on your driving/camping habits. We will determine these variables with you and find a cost effective solution that suits your needs.

All our systems use MPPT charge regulators. Usually integrated into a DC/DC charger that can also be fed from your alternator. That way you can charge while you are driving and while the sun is out and a panel connected. Most DC/DC chargers we use have a green priority setup. This means solar power always has priority over alternator power. The DC/DC charger will use what it can get from solar and top up the rest from the available alternator power.
