Touchless Car Wash System with Full Drying for Premium Unattended Bays
The Series 7S from HeyCar is a touchless car wash system with full drying for premium 24-hour sites.
It takes the complete Series 7 wash, including lava foam, and adds two 5.5 kW side air blowers.
Together with the 16 kW top dryer, that gives 27 kW of total drying power.
So customers can drive away without manual wiping, even when no staff are on site.
Why full drying matters at a 24-hour site
A premium wash loses its value if the car leaves wet.
At night, no attendant stands at the exit with a towel.
Without side drying, water runs from the mirrors and door seams onto clean paint.
Then the driver sees streaks a few minutes later and remembers the wash as unfinished.
The 7S removes that problem because the side blowers dry the vertical surfaces in the same cycle.
As a result, the last thing a customer sees is a dry car, not a wet one.
What the side blowers change
- Mirrors: drivers get a clear view on the exit road instead of stopping to wipe the glass.
- Doors and sills: water no longer drips onto the sills when the customer opens the door.
- Tall vehicles: SUV, pickup and van sides are large, so side air makes a visible difference there.
- Exit lane flow: customers leave at once, so the bay frees up for the next paying car.
- Staff cost: you need no drying crew, which suits unattended 24-hour operation.
In short, the blowers turn a strong wash into a finished product that customers pay top prices for.
Who this machine is for
This touchless car wash system with full drying fits operators who sell top-tier programmes without staff.
- Premium unattended bays where customers scan a QR code and pay for a full programme.
- Gas stations serving drivers who want to leave dry and quickly.
- Sites with SUVs, pickups and vans, because the 7S washes vehicles up to 6.2 × 2 × 2 m.
- Upgrade buyers who want lava foam and full drying in one machine.
How the touchless car wash system with full drying works
- Scan: first, the Pepperl+Fuchs sensor suite reads the vehicle size and position.
- Underbody: deep high-pressure underchassis jet-spray bars and 16 nozzles rinse the chassis.
- Pre-soak: next, shampoo goes on through the automatic chemical proportional metering pump.
- Pressure wash: the 15 kW German pump then sprays at 100 kg through 15 arm nozzles.
- Lava foam: multicolour waterfall foam covers the whole body.
- Water wax: a wax coat goes on as standard.
- Full air dry: finally, top fans and side blowers dry roof, doors and mirrors together.
Each car spends 6–8 minutes in the bay.

Site and installation requirements
Reserve a bay of at least 7.5 × 4 × 3.2 m for the 7S.
The machine measures 7 × 3.7 × 3.2 m.
It needs a 3-phase 380V or 220V supply at 50Hz or 60Hz.
The series table lists 35.05 kW total power, and your quotation confirms the final electrical load.
Plan water supply and drainage too, while the free 1000 L tank stores water for peak hours.
Running costs per car
- Water: 120–150 L per car.
- Electricity: 1.2 kWh per car.
- Chemical: 20–40 ml per car.
Also consider the optional water recycling system, which saves more than 85% of water.
Buyers usually order it with the machine, so the plumbing goes in once.

Frequently asked questions
Can customers really leave without wiping?
Yes. The side blowers dry doors and mirrors, so most drivers leave straight away.
Still, small spots near hubs or door handles can need a quick touch-up.
What is the difference between the 7 and the 7S?
The wash is identical. The 7S simply adds two 5.5 kW side air blowers for full-body drying.
Is a touchless car wash system with full drying right for a staffed site?
It works there too, although staffed sites often save by choosing the Series 7 and hand-drying.
Does it clean interiors?
No automatic machine does. Use the free vacuum to offer an interior service.
