FAQs

Is it legal to install the system? 2016-05-06T12:55:59+00:00

Yes the system can be installed legally, however only a CNG licenced mechanic can complete the installation. Once completed then 3 x compliance plates are attached to the vehicle in addition to the h2 signs affixed to number plates.

How much does it cost to install the system? Do you have any financing options? 2016-05-06T13:48:23+00:00

The system is priced between $7200 plus GST to $20,000 plus GST dependent on vehicle size, configuration and usage. We are working on finance otpions and will have these published soon.

Do we have any guarantee about fuel consumption reduction? What will happen if the fuel consumption doesn’t decrease? 2016-05-25T12:37:01+00:00

We can confirm and assure clients that they will achieve at minimum 10% fuel reduction. In some cases it will be more. Maximum fuel savings will be achieved with driver training, driver attitude and conduct. This is because as hydrogen is injected then the driver will immediately notice the increase in power. If he/she then reduces their diesel output (depress the accelerator pedal less or more as required) then maximum savings are achieved. However, if on the other hand the driver notices the increase in power therefore he accelerates even more, then the savings are reduced. We are guaranteeing that if they don’t achieve the fuel reduction as indicated then we will remove the system, return their vehicle to its’ original form and fully refund the cost.

Do we have any guarantee on the system and for how long? 2016-05-06T13:08:12+00:00

We do supply product warranty for 2 years.

Is the system safe? 2016-05-25T12:37:59+00:00

Safety is our main concern and for this reason hems global spent the last 4 years on research and development in order to establish the safest system possible. Hems Global uses only hydrogen rated parts in our system and have not spared any expense in order to source the best equipment. All of our system parts exceed the required safety standards both locally here in Australia and international standards.

Is the system certified? 2016-05-25T12:39:05+00:00

Yes. The system is certified by Dr. Hien Ly. Dr. Ly  is the on the board of Compressed Natural Gas (CNG) and he also co-wrote the standards locally and overseas.

How long will the system last? 2016-05-06T13:14:33+00:00

The system will last for many years, however it’s the customers responsibility to include it in their regular maintenance routines. (HEMS will instruct customers upon installation as it is compulsory).

Do we need to refill the system with hydrogen? 2016-05-25T12:40:14+00:00

Yes. The system will require filling similar to any vehicle. Hydrogen cylinders can be refilled via the filling receptacle installed as part of our hydrogen based diesel reduction system. Hems Global has the filling solution available now and more stations are being built for increased convenience.

In the savings that you mentioned, did you included the price of hydrogen? 2016-05-06T13:16:35+00:00

Yes. All savings offered are calculated including cost of hydrogen.

What happens if the system breaks after the warrantee period? 2016-05-06T13:20:01+00:00

If the system has operational problems or technical issues are experienced by the client then HEMS will investigate the problem to ensure no third party tampering has occurred first. After evaluation and it’s just normal parts failure then HEMS will replace the faulty parts and charge the client for parts only. However, if it is discovered that the system has been tampered with then full service and technical charge will apply plus parts.

When we buy the system do we have to pay for installation? 2016-05-25T12:41:56+00:00

Yes, however Hems Global are willing to extend staff training (training is provided by a Registered Training Organisation (RTO)) to a select few as an introductory promotion. The first three rounds of training will be free of charge and offered to mechanics/employees of potential clients. After this all training expenses will be borne by the trainees themselves. However Hems Global engineers will still be required to do on-the-spot checks to ensure the integrity of the system at no cost to the client.

How expensive is it to maintain the system? 2016-05-25T12:44:31+00:00

The system maintenance is relatively inexpensive or minimal. Customers can include HEMS system in their preventative maintenance program and services involve general visual inspection to ensure wiring and pipe connections are secure and leak free.

Can we test the system first, before we buy it? 2016-05-06T13:37:02+00:00

We are currently running a promotion with our sales campaign and we are offering free trials to a select few. You will need to be quick to take advantage of this limited offer.

What happens if the vehicle with the system crashes? 2016-05-06T13:35:57+00:00

The system installation is crash proof and cylinder mounting is rated to more than 10g. When the system is installed HEMS takes into consideration the possibility of a crash and therefore safety is paramount. We therefore install the cylinder in a location safe from harm so it is safeguarded.

How complex is the system? 2016-05-06T13:40:09+00:00

The system is very simple. HEMS spent many years of research and development in order to come up with a design that is simple, effective and easy to install. We have experienced engineers, draft engineers together with our resident expert continually working to ensure all aspects of our system is improved both cosmetically and in terms of performance but more importantly we are always working to increase safety of our system.

What is the maximum range the vehicle can travel without running out of hydrogen? 2016-05-06T13:44:10+00:00

That would depend on what cylinder(s) are installed in the vehicle. Ie E Cylinder 4000 litres and on average 1200 kms or G Cylinder 8000 litres on average 2500 kms. We can extend the range by installing 2 or more cylinders concurrently to double the range.

What is the exact size of the HEMS unit in litres, to allow estimate where best fitted? 2016-05-06T13:46:48+00:00

The Hems unit is not measured in litres per se; however to give you an example: an E Cylinder weighs 28 kgs and it is 1200mm long with 220mm width. The actual unit size including all parts and plumbing connected would mean an actual space of 400w x 1400L x 360h all in millimetres. G Cylinder is slightly bigger weighing 48 Kgs, and system dimensions are 400w, 1800L and 360H – again measurement are in millimetres.

Who are your suppliers? 2016-05-06T13:42:07+00:00

All parts are supplied by genuine hydrogen manufacturers and system designers, however HEMS manufactures and supplies the patented control unit here in Australia therefore Hems Global Limited is your supplier.
