HW UNDER CHASSIS WASH – High Pressure Wash
The UNDERBODY WASH is a high performance touchless wash system ideal for washing the under chassis of heavy vehicles.
Features include:
- Provides a clean vehicle for NHVR inspections or mechanics to work on
- Simplifies the process of identifying mechanical issues
- Enhances road safety by minimizing oil leaks onto the roadway
- Vehicle drivers can easily operate and keep it clean
- Requires minimal maintenance by simplity of design (no moving parts)
- Only requires cold water for improved energy efficiency
- Suitable for various heavy-duty vehicles, including trucks, buses, and coaches.
- The spray bar activates automatically when the vehicle passes through the washbay and is detected by a loop sensor in the ground. Others still use low cost light barriers that fail in high humidity conditions.
- A range of dry run protected pumps from 11kw to 32 kw depending on speed of wash desired and the type of clean required.
The World’s most effective underbody wash system
Our under chassis cast in manifold was designed by our founder Varuna Krishnaratna in 1997. It revolutionised the heavy vehicle underbody washing industry buy enabling a low cost civil works option – particularly on existing wash bays where down time for civil works needed to be minimised.
Since then it has been copied widely in the industry around the world. However subtle engineering improvements from the designer of the original manifold, means the Arrow Hawke units have now all but eliminated slab fracture and fatigue prevalent with lower cost copies provided by others.
The basic unit comprises a galvanised steel or stainless steel fabricated manifold. This framework is 3000mm wide and can be installed in existing or new truck and bus wash bays.
Technology
The equipment is automatically started thanks to photocells in all three versions and optional extras that complete the wash process of any commercial vehicle type, which makes it a totally dynamic and adaptable system.
Auto start with photo activation, low water level sensors, integrated automation system.
Programable Oscillating Spinners
PLC oscillating spinners to track the vehicle as it passes for optimal vehicle coverage.
