WorkZone

All primary functions needed for filling and cleaning are easily accessed via the ALPHA evo WorkZone. A logically placed FluidBox with colour-coded icons helps keep the system clear and safe  to operate. This greatly reduces set-up and clean-up times.

  • Easy and convenient
  • All functions grouped together
  • Colour coded for safety
  • Self-fill connections
  • Remote engine throttle and pump controls
  • 15 l CleanWater tank

A 180 l onboard chemical storage locker is standard.

Pump

ALPHA evo features HARDI's new and improved 464 model diaphragm pump. A redesigned cylinder head reduces pressure drops by improving flow in the diaphragm tops.

  • Self-priming
  • Able to run dry without damage
  • Easy to service
  • Grease-lubricated crankcase

For easier service there are new integrated lifting hooks and the greasing points for the front and rear bearings have been moved to the front of the pump. The cast conrod support ring has also been redesigned to improve durability.

Most obviously, new black covers protect the pump from mud and water.

EasyClean filter

The EasyClean filter is a high capacity suction filter. The condition of the filter can be constantly monitored via a SafeSpray vacuum gauge.

This ensures that the filter is only cleaned as needed. Simply twisting the lid through 90° will simultaneously close the inlet valve and open the filter for inspection.

CycloneFilter

The HARDI CycloneFilter is a unique  pressure filter that uses a high-speed circular flow for powerful self-cleaning. This 'cyclone' action increases the speed of the liquid against the filter screen, making the self-cleaning action much more effective.

The CycloneFilter also has a boost function allowing the filter to be flushed when needed.

The filter's design means it can be mounted upright, reducing the risk of spills and pressure loss during inspections.

DynamicFluid4 liquid system

The fluid system on the ALPHA evo is a new concept developed to obtain shorter response time and more precise application in the field.

 In a traditional fluid system, regulation is driven by what is already 'historical' data. For example if RPM is increased, the flow will immediately become too high at the nozzle. The spray computer will quickly regulate the excess pressure but the application rate will have been elevated in the meantime.

The DynamicFluid4 system can calculate the impact of increasing RPMs and regulate the pressure instantly. This pro-active property is based on four sensors in the fluid system measuring RPM, regulation valve position, flow rate and pressure. Using new software and a unique ceramic regulation valve, DynamicFluid4 offers market-leading performance and precise rate control.

Main Tank / RinseTank

The Main Tank has a low profile and a deep sump ensuring a low centre of gravity. Its position between the axles preserves the sprayer's centre of gravity regardless of fill level.

The deep sump means the chemical agitation is very effective, and the tank can be completely emptied on slopes of up to 10 degrees.

The Rinse Tank (410 l on APLPHA 3500/4100 and 600 l on ALPHA 5100) is integrated into the Main Tank and can be filled from the platform or ground level. The capacity is ample for cleaning the sprayer inside and outside. 

With its smooth internal profile, no part of the Main Tank is shielded from the rinsing nozzles and there is nowhere for sediments to pool. The outside is also very easy to clean.

TurboFiller

The HARDI TurboFiller can handle large quantities of powders and liquids. Its high capacity is achieved through a combination of high vacuum and liquid rotation produced by a TurboDeflector inside the hopper.

High pressure water creates a powerful rotation inside the hopper, thoroughly mixing powder or liquid before it is sucked into the sprayer. Maximum capacity is achieved when the TurboFiller is more than half-filled with water.

A spring-loaded bracket with transport lock lowers the TurboFiller to 95 cm above the ground for safe and easy use.
