J.U.M. - Model VE 222 - All Heated 2-Point Prefilter /Sample Sequencer
From Heated FID Analyzers - Sampling Accessories
The Model VE 222 is an efficient, all heated and low pressure drop 2-stream sample sequencer, filter and interface for removing solids from two gaseous sample streams. The Model VE 222 utilizes two independent permanently installed all stainless steel mesh sample filters and two independent all stainless steel sample valves in a thermostatic controlled oven to prevent the loss of high molecular weight hydrocarbons or condensation of water.
Product Details
The permanent sample filters are regenerated in a matter of seconds by back purging them with high pressure air or nitrogen
The Model VE 222 can be installed in the system, or directly at the sampling spot and, with its back purge system for the two sample filters, offers extended up times at comparatively low maintenance.
A calibration gas inlet offers the ability to test and calibrate a complete sample train that may include the heated sample lines. Our special rear adapter-plate system allows cold-spot free coupling of three heated sample lines inside the heated oven (2 x sample in, 1 x sample out) without the need of special tools.
Additionally the Model VE 222 offers five regular sample outputs under ambient pressure for connecting various analyzers to the unit making it the perfect centerpiece for a sequencing multi component sampling system.
Features
- Two sample inlets, one main sample outlet with capability to couple 1 heated FID and four more gas analyzers
- The five regular sample outlets work at ambient pressure to connect other gas analyzers to the same sample source
- All sample wetted components inside the heated chamber
- Oven temperature 190 deg.C (374 deg.F)
- Two permanent heated stainless steel sample filter, 2 micron mesh
- Sample filter back purge system, allows sample filters to be cleaned independently without dismantling
- Programmable automatic sample filter back purge system optional
- Remote control for valve operations sample, calibrate and filter back purge is standard
- Integrated heated sample pump w. up to 25 l/min capacity (unrestricted flow)
Major Applications
- Sample Interface for continuous gas emissions monitoring systems at two sampling points, for example before and after a thermal or catalytic oxidizer
- Diesel raw exhaust analysis before and after catalyst and/ or soot filter
- Gasoline raw exhaust Analysis before and after catalyst
- Stationary diesel engines two point
- exhaust analysis
- Removing particles from a gaseous sample where condensation of heavy hydrocarbons is not desirable
