Frequently Asked Questions : Greentech E7

How do I find out more about the E7 Robot?

We suggest you either fill in the online form, email or call us on the number most local to you and we’ll arrange to visit you to discuss your requirements further. Some of our clients wish to see one in operation, and we can arrange that for you, hopefully reasonably locally. During our visit we will carry out a technical site survey in order to make sure we have all the information to implement a smooth installation.

Can I buy a Greentech E7 robot without the Bodyshop Revolution Production Logic process?

Yes of course, many of our customers do. If you have a specific issue with repair capacity, particularly around body filler, priming and drying then the E7 is an ideal first step to greater throughput. For some, our Production Logic process is too much to take in one step, so an easy way to make significant changes to your workflow in the metal/prep department would be to install an E7 robot in your workshop above 6 or so stalls. Adding Production Logic later on is an easier step if you wish to do so.

Can a E7 Greentech robot be fitted into my existing workshop?

An E7 robot can be fitted into most workshops. It is suspended, so we’d need to make sure that we have enough height (typically about 5m or 16 ft), and that what we’re hanging it from can structurally support the 3000 pounds it weighs with the suspension framework.  We would need to carry out a technical site survey prior to installing the equipment, so that we can ensure it will fit and supply the robot to your specification.

How long does it typically take to fit an E7 robot into my workshop?

Expect two of our certified engineers to take approximately 4-5 days to carry out the installation, pre-testing and calibration of the equipment if you are having the full length 20m (65ft) machine. You will need to make sure that you can let us have individual work bays as we construct it during this time. It’s constructed on the floor in parts, then lifted and suspended in place.

How quickly does the E7 dry paint and body filler?

At the same speed as all of our other robots, with the exclusion of the E1 hand lamp (that one is slightly less powerful than its big brother E5, E6 and E7) Typically body filler takes about 1 minute to completely cure ready for sanding, and primers typically take about 1 minute per coat, including flash-off passes and bake cycle. It’s not uncommon with small repairs, for bondo to be applied, dried, sanded – for primer to be applied, dried and sanded all in about 20 minutes – start to finish, the complete operation.

Can the E7 Robot dry displaced parts?

Absolutely, you can dry almost any part under the E7 machine, especially as the complete machine will swivel through 360 degrees as well as lay horizontally at any height – perfect for roofs, hoods, trunks or displaced bumpers. Many of our clients paint most parts off the vehicle and the E7 is an idea way to facilitate that and speed the process prior to topcoat paint.

What types of paint and fillers will the E7 dry?

All solvent or waterborne paints used in the automotive industry including but not limited to; Sealers, Primers, Epoxy Primers, Basecoats, and even Clearcoats. You do not need to change any of your products to work with the E7 machine, however we may use slower hardeners in some of your materials as adding accelerators increases die-back and gloss drop where applicable, and they have little benefit under the equipment anyway – it dries within a minute or so, without expensive additives. Most people use it for body fillers and primers primarily, but it can be very useful as a tool to cure conventional booth dried products a secondary time in order to facilitate remedial work or faster refit cycle. It;s worth also knowing that if you have to remove decals from vehicles, run the E7 past it, and then peel away with ease!

How quickly does an E7 dry paint?

Quicker than any other method within the automotive industry including conventional convection drying or electric IR. Its 3.5µm wavelength is specifically to dry automotive paints extremely fast. Typically, exposure to the catalytic lamp for just over a minute will cure paint to 98% (normal spraybooths after about 30 minutes cure to about 80%). Because the robot has to move over an area of the vehicle, this time will be extended. Note that the robot moves about 1m (3ft) per minute as an average.

I’ve tried roll-on priming historically without much success - you promote this with the E7, so how is this different?

There are some key differences with the way we approach roll priming with outstanding results. Please follow this link to understand more about our unique roll-on priming process

What happens if I get a paint defect while spraying or roll-on priming?

The incredible thing about the E6 is that you can just bake it off with the robot, rectify the issue and carry on painting, with minimal downtime. No waiting, no moving vehicles or significant hold ups of other work upstream.

How easy is it to operate?

Very simple. All you need to do, via the joystick is manoeuvre the E7 to the location you are working. Move it to the start position and click the ‘start’ on the touch screen, then move it to the finish point and click the ‘finish’ on the screen. Now move it out of the way from your work area and set this as ‘home’ When you’ve put in your bondo, or rolled on your first coat of primer, select the product you are drying on the touch screen and press ‘Go’. The robot will move to the start position quite quickly, will then proceed to dry the product until the end point and park itself back in the home position for you to carry on with your work – typically all in about 1-2 minutes.  

How much operator training do I get?

We charge training on a day-by-day basis, so you can have as much as you feel you need, and can always request more further down the line. Typically we would spend about 5 days at your shop in order to ensure you understand fully how to operate the equipment, and to deal with different substrates, paint systems and challenges that everyday body repair throws at you!

How many passes does the E7 robot make in order to dry paint or fillers?

For filler it’s just one pass to be completely dry – so about 1 minute of operation. If Tech’s want slightly softer filler to sand back, then we have a quicker setting for that. For primer, we pass just once per coat. So we apply a coat, pass the robot over if for what we call a ‘flash-off’ pass, then cool the panel below 30 degrees C (85F) with an airline so the next coat of primer doesn’t boil and pop the solvent, then pass the machine over the next coat. Repeat this 3-4 times, and the final pass is changed to ‘bake’ so it cures the product completely in just one final pass. The primer is then cooled and can be immediately sanded.

How hot does the vehicle panel temperature get, and can it do any damage?

The hottest primer bake pass would be at 110 degrees C (230F). Although this seems hot, it’s for only about a minute, and very localised, so there is no detrimental effect on fiber optics, plastics or electrical components. Gas catalytic machines from other suppliers often need items such as plastics, belt mouldings, headlamps and tail lamps to be covered with aluminum foil to reflect the intense heat they generate because of a shorter wave IR. This is not the case with the Greentech E7.

What on-going maintenance and housekeeping is required?

For the first year we service the robots within the purchase price every 6 months. After that you are encouraged to take our one of our maintenance and service plans to give you further coverage for year two and beyond. This will include two services per annum, and calibration of the equipment. We provide general housekeeping to be carried out once per week by one of your Tech’s team, which isn’t onerous but keeps the machine clean.

Are there any additional things I should know about the E7?

We think this is the state-of-the-art drying equipment, which surpasses all of our competition as well as electrical IR or traditional convection based booth drying. Here are some things you might find useful:

  • Our robot drives super smoothly, therefore eliminates any kind of jerky movement, especially from dust build-up on the rails, eliminating dirt dropping in your beautiful paintwork.
  • Our Catalysts last about 12 years of use, and operate at a lower temperature ensuring nothing needs to be covered with aluminum foil or high temperature car covers.
  • Our touchscreen and setup is quick and simple to use, with the robot knowing where its home position is in order for it to automatically get out of the way to allow you to continue to work.
  • All of our robots are ETL certified and meet local and national requirements for all countries that we sell into.
  • The limited number of moving parts help achieve years of trouble-free running, with minimum maintenance required.
  • If you don’t like our gorgeous green colour, you can specify it in mid-grey (unfortunately at a slight cost, as they are powder-coated individually for you).
  • If you also require a new booth at the same time, we can put you in touch with sympathetic booth suppliers who will build the booth with strengthening in the side walls to support the robot to eliminate having legs. It can also be built with side-load doors and rail systems for super-fast loading.
  • Our local team of trainers, telephone support staff and engineers are on hand to ensure you get the best, most prompt service – we speak your language.
  • We keep most spare parts locally, and the equipment is specifically built to include as few bespoke electrical parts as necessary to ensure a local supply.
  • Your E7 is supported by factory trained and certified engineers who have worked within the collision industry for many years, and understand your requirements and challenges when working with you.

Finally, imagine being able to work continuously – no lines or queues of vehicles waiting for other techs in other departments to be free to work on it. Imagine using less masking materials and paint with significantly less energy. Imagine not having to use a prep deck for priming, and to be able to dry primer completely in just a couple of minutes to enable what we call ‘continuous workflow’. Cars stay in one place for longer, techs can continue to extend what they do to achieve shorter cycle times, and with our unique roll priming technique, vehicles will literally fly through the shop, while they’re standing still.
