S-7 Overview

This area is built to answer a B2B buyer's first questions quickly: what this machine is, where it fits, and how it differs from the other models in the range.

Why buyers consider S-7

100–120 kg maximum pressure delivers a clear performance step above S-6 within the same 16 kW power class.

Hanging rail type with 3 m pipeline separation improves chemical-line layout flexibility on commercial sites.

Full touchless wash stack plus embedded mobile drying (4 × 4 kW fans) supports wash-and-dry throughput.

Dual PLC, parking detection and mechanical + electronic anti-collision match premium automation expectations.

Water wax varnishing, automatic liquid dispensing and LED guiding lights complete the chemical and guidance package.

S-7plus shares core parameters with S-7 for buyers who need the plus-series appearance positioning.

Selection advice

Choose S-7 when pump pressure above 90 kg matters for your market, while keeping integrated mobile drying and the hanging rail S-Series layout.

Pressure class

S-7 reaches 100–120 kg — the high-pressure tier at 16 kW before S-19's 22 kW flagship.

Layout

Hanging rail with 3 m pipeline separation differentiates S-7 from rail-type S-6.

vs S-19

Choose S-19 for 22 kW output, 100–140 kg pressure and 3-year complete-machine warranty.

Common Questions

These answers are written for pre-quotation conversations, so they focus on wash method, fit, configuration and support.

How is S-7 different from S-6?

S-7 offers higher maximum pressure (100–120 kg vs 60–90 kg), hanging rail layout and 3 m pipeline separation. Both include integrated mobile drying.

Does S-7 include air drying?

Yes. Standard configuration includes injection molded embedded mobile air drying with four 4 kW fans.

What is S-7plus?

S-7plus shares core parameters and features with S-7 for buyers who need plus-series positioning in the same pressure class.

What installation size is required?

Installation size is approximately 7 × 3.5 × 2.9 m with L-arm central rotation.
