Equipment and Products
Envirometrics Inc. can supply pilot-scale control equipment for pre-design studies. We are the co-developer of the HVS3 and HVS4 and have units available for short-term rental. Surplus equipment is for sale. Also available are copies of the book Benefit-Cost Analysis of Air-Pollution Control.

Pilot Control Systems
Envirometrics can supply a pilot-scale baghouse, scrubber, air stripper, or incinerator for determining design parameters, process applicability, or the performance of new control techniques. Sizes, operating details and rental rates are provided on the linked page.

High Volume Small Surface Sampler (HVS3)
The HVS3 is the ASTM standard method for recovering (potentially contaminated) dust samples from surfaces for chemical analysis. The HVS4 is a smaller, more portable version. The HVS4 has not been validated as equivalent to the ASTM method but the results have been found to be similar. CS3 has both an HVS3 and an HVS4 available for short-term rental. Both are also available for sale. A description of the HVS3 and HVS4, contact information for CS3 and a copy of the operating manual are provided on the linked page.

Benefit-Cost Analysis of Air-Pollution Control, Halvorson and Ruby
