Volvo A35D Articulated Dump Truck with RESPA: No HVAC maintenance in 6 years of Landfill Operation!
Read the RESPA Case Study: Volvo A35D Articulated Dump Truck with RESPA: No HVAC maintenance in 6 years of Landfill Operation [PDF]
Recent interviews with the operator and head mechanic in a Florida Landfill reveal this incredible story.
A major maintenance issue in landfill operations is operator cab heating and air conditioning systems. Typically the HVAC requires a major service every 3-4 months of operating time in a landfill due to the high-debris environment. According to the maintenance supervisor, a properly functioning HVAC makes a huge difference in machine productivity because operators can be exposed to high heat, humidity and overwhelming odors in the cab. A properly functioning HVAC is critical path to maintaining a productive machine operator.
Six Years ago, they started with Gideon®, our 1st generation Cab Air Quality System:
The A35D pictured above was purchased 6 years ago to haul dirt to layer over the garbage in the landfill. It runs constantly and is exposed to huge amounts of airborne particulate, odors and flying landfill debris. When purchased it came equipped from Volvo with the Sy-Klone Gideon HVAC Precleaner/Filter/Pressuizer system.
According to the head mechanic who has serviced this machine since it was new, it has never had any maintenance done to the HVAC system. The operator reports that the HVAC works flawlessly with the HVAC producing "like new" amounts of cold air. The cab, even after 6 years of run time, is still pressurized.
In 2011, we upgraded to RESPA-CF® Vortex HyperFLOW™, our 3rd generation Cab Air Quality System:
In June of 2011, Sy-Klone engineers installed the RESPA-CF Vortex HyperFLOW Cab Air Quality System on the A35D for a field evaluation of the device. The operator and head mechanic were interviewed on February 22, 2012 about the device's performance. The mechanic discussed the amazing history of this machine and the operator confirmed the mechanic's statements regarding the function of the HVAC and reduction of odors in the cab.
Benefits of upgrade:
- The RESPA-CF Vortex HyperFLOW provides substantially higher efficiency MERV 16 filtration.
- The new system includes a Cab Pressure Monitor which tells the operator and mechanic if the cab loses pressurization.
- Cost avoidance: the fresh air filter in the RESPA-CF Vortex was changed for the first time after more than 1000 hours of run time. During this time the cab never lost pressurization and there were no mechanical failures in the HVAC system.
This field evaluation not only demonstrated the effectiveness of the new RESPA-CF Vortex HyperFLOW system but it confirmed that Sy-Klone's Gideon technology from the first generation through its latest version have all produced satisfied customers and reduced cost of operations. Truly a win-win.
