RESPA®-CF Vortex HyperFLOW® Product Validation

http://www.sy-klone.com/

Installation Site:

Landfill

Installation Dates:

June 20th through 23rd of 2011

Test Completion Date:

October 31, 2011

Scope:

The purpose of this test is to evaluate the RESPA CF product in real world conditions. Six machines were chosen to evaluate the RESPA CF structural integrity and filter life. Included in the test procedure is a visual inspection of each system upon site visit and collection of system performance data. Not included in the test procedure is correction of current cab seals and pressurization, or any aspect of Series 9000 or OPTIMAX. System restriction of 1.0 inches of water column, October 31st or 1000 hours of run time per machine under evaluation, whichever occurs first.

Machines:

• Caterpillar D8R (2): Used to move landfill waste material in cell. • Caterpillar D6R LGP: Used to move soil in landfill cell. • Caterpillar 836H: Used to compact landfill waste material in cell. • Volvo A35D: Used to transport soil. • Volvo EC330CL: Used to excavate soil for cell use and install piping for landfill gas collection.

Product(s) Installed:

• RESPA-CF Vortex HyperFLOW* - R502171010008 • RESPA-CF Vortex HyperFLOW* - R502131010008 (4) • RESPA-CF Vortex HyperFLOW* - R502121010008 • Hour Meters • Various Sy-Klone installation products including: mounting plates, adapters, clamps, hose, and tubing.

* Preproduction units: 24 volt, Deutsch connector, screened inlet, rain cap, MERV 16/EU P2 slotted ejection filters.

Installations:

• D8R (1 of 2) • D8R (2 of 2) • D6R LGP • 836H • A35D • EC330CL

Data Collection:

Data was taken from each machine available during each visit. Machines were down for service on several occasions and were not always available for data collection. Data collected includes: machine hours, cabin pressure at each A/C fan speed setting, voltage input to RESPA CF, current draw of the RESPA CF, pressure drop across the RESPA CF filter, and RESPA CF operation hours. Data was collected with the machine running unless noted otherwise.

Results:

Visual Inspection – There was no visible debris build-up in the inlet or ejection areas of any RESPA CF during the 17 inspection visits. No cracks or deformation was apparent in the RESPA CF housings or mounting feet. (Appendix A) Removal of the filters showed no signs of internal debris build up. (Appendix A) The filter media showed no paper separation or holes. The pleats were not impacted with dirt. (Appendix A)

Data Collection – Only the Caterpillar 836H and the Volvo A35D produced pressures above 0.20 inches of water column within the cabin. The other four machines provided erratic pressure readings and often showed no pressure within the cabin. (Appendix B) With A/C blower motor set to high, system restriction ranged from -0.49 to -0.14 inches of water column averaging -0.32 inches of water column across all of the units. The greatest system restriction was reached by D8R (1). 0.38 inches of water column was recorded at 594.1 hours. The same D8R measured 0.365 inches of water column at 689.1 hours. The RESPA CF system restriction followed a parabolic trend as the restriction increase over the first 50 – 60 hours was equivalent to the increase over the several hundred hours following. Every machine would occasionally produce system restriction readings that were lower than the previous system restriction recording. (Appendix C) Current draw ranged from 2.5 to 6.34 amps averaging 4.94 amps across all of the units. Machine voltage ranged from 24.73 to 28.40 volts averaging 27.66 volts across all of the units.


Conclusions/Comments:

The landfill environment was harsh on the machines. There were many instances of machines being down for service. The RESPA CF systems required only three service actions. First, the relay used to power the D6R unit stopped receiving ignition power. Second, a fuse of inadequate rating was used in the A35D and blew due to the start-up current of the RESPA CF system. Third, the 90° elbow fell off the A35D about 3 weeks after the initial installation. This could be due to or a combination of the clamp placement, clamp tightness, and road vibrations seen by the A35D. The adapter was reinstalled with the same clamp and has been issue free for 3 months. The RESPA CF outlet has been extended slightly to increase the mounting surface. The mounting locations of the RESPA CF systems were ideal as each showed no signs of collecting large debris and were easily serviceable.

Though cabin pressures were minimal in 4 out of the 6 machines, the decay in cabin pressure, over time, is evident in all of the machines. The cabin pressure decrease was minimal only dropping approximately 0.10 inches of water column over the duration of the test. The decrease in cabin pressure can be correlated to the increase in the RESPA CF system restriction.

The filter media used in the RESPA CF is approximately one quarter that of the RESPA SD. Based on the decreased filter media, the system restriction limit was expected to be reached between 250 to 500 hours. I would expect, based on the data collected, for every system to reach 1000+ hours before reaching the restriction limit. This data shows the advantage of the HyperFlow technology. Debris that has entered the filter housing of the RESPA SD is trapped in the housing. Any debris that falls off the filter cannot be ejected. Debris that enters the RESPA CF filter housing can be ejected at any time. If debris is released from the filter, due to backpressure from the cabin i.e. slamming a door, it will re-enter the airflow and be ejected. This unique process can explain the occasional decrease in system restriction and extended filter life.

Variances in system current draw and voltage input seemed to have no effect on system performance. The current draw suggests a need for 15 to 20 amp fusing.

The operators switched machines often. There were no negative comments and one operator noted that the cabs seemed cleaner.
