The Western Australian Mining- especially up North in the Pilbara- is one of the harshest and dusty environments. known to man. With very little rain fall, scarcity of water for dust suppression and temperatures that can exceed 52 degC- then this is where our RESPA SD / SDX Ultimate PFP- HVAC solutions thrive!

The Western Australian Mining- especially up North in the Pilbara- is one of the harshest and dusty environments known to man. With very little rain fall, scarcity of water for dust suppression and temperatures that can exceed 52 degC- then this is where our RESPA SD / SDX Ultimate PFP- HVAC solutions thrive!

A large International Mining Company has endeavoured to improve the HVAC PFP Technology on their HME, which as not proving successful as well as they were incurring extensive operating costs.

Subsequently, they evaluated our RESPA SD PFP Solution on their D11 Track Dozers. Track Dozers are one of the most severe applications due to not only dust exposure but strong vibration when compared to rubber tyred machines / vehicles.

Prior to the installation of the RESPA PFP Units the following was occurring:

  • Dust was entering the Cabin in copious amounts, as well as DPM (Diesel Particulate Matter) from the Dozer engine exhaust.
  • Some HVAC's PFP's had the air entry blocked with rags because of the contamination entering the Cabin.
  • Previous HVAC PFP Filtration design was inadequate- Filter Element service life was between 60-100 hours.
  • Cabin positive pressure was not being met- especially in the case where the external air PFP was blocked with rags. 
  • Recirculation Filter Panel would block within 60-100 hours.
  • HVAC was not working- optimum thermal exchange was not sufficient for Operator comfort.
  • Reports that when the current PFP was installed with new Filter Element, that initially the Cabin pressure was so high that the Operator had difficulties closing doors, they would feel pressure on their ears and get headaches. This would subsided fairly quickly as the Filter Elements would soon block.

The Dozers where then installed with a RESPA SD PFP Technology with Sy- klone MERV16 Filter Element.

 The following results after more than 1,500 hours have been:

  • The RESPA PFP has shown no negative effects mechanically- remember that Track Dozer create severe vibration. 
  • Increased health / Clean Cabin environment for the Operator with no particulate from external air and elimination of DPM.
  • Optimum Operator comfort with excellent thermal cooling / heating.
  • Positive pressurisation of Cabin of between 80-100 pascal- note RESPA PFP's have inbuilt safety and will never over- pressurise Cabin.
  • Extended Filter Element service life of 500 hours- whilst maintaining optimum Cabin pressure, optimum HVAC thermal exchange and clean / fresh air flow.
  • Reduced HVAC Maintenance.

The site operates approximately 60 x piece of HME (Heavy Mining Equipment) and the ROI Analysis depicts that this one site only will save more than $2.5 million / annum in Filter Elements and Labour alone- not counting Productivity gains, HVAC Maintenance / component replacement, etc.

It goes without saying that the site / company is now implementing RESPA PFP Technology on all their new equipment, as well as a retrofit program on existing equipment.

The installation of our RESPA SD / SDX Ultimate PFP- HVAC solution will assist them in: 

  • Increased health / Clean environment for the Operator with compliance to Worksafe OEL (occupational Exposure Limits). 
  • Optimum Operator comfort with excellent thermal cooling / heating.
  • Extended Filter Element service life.
  • Reduced HVAC Maintenance.
  • Massive savings directly and indirectly.

RESPA SD provides optimum filtration and clean External Air whilst the RESPA SDX will provide for filtering / cleaning of the Recirculation Air supply where airborne contamination may enter the Cabin when opening doors, Operators boots, clothing, etc.
