Continuous Emission Monitoring & Relative Accuracy Test Audit (RATA) Equipment:

The ESC CEM and RATA lines of equipment include RATA 3-Point Samplers, CEM probe assemblies, in-stack sintered filters, sample conditioners, heated sample lines and a variety of single and multi-station temperature controllers.

RATA 3-Point Samplers

The RATA-3 Valveless 3-Point Sampler (shown at left) utilizes an orifice manifold to equally control flow from three extraction points for simultaneous 3-point sampling. The manifold includes a calibration gas inlet fitting at the merge point of the three sample pathways within the manifold. The RATA-3.5M Manual 5-Way Valve Sampler and the RATA-3.5 Solenoid Actuated 5-Way Valve Sampler perform sequential, individual point sampling and calibration gas introduction without traversing. The RATA-3.5 Sampler includes a remote control module with control cable for remote valve actuation and valve position monitoring. Each sampler includes a heated 2" probe sheath and a heated valve/filter case with cylindrical filter holder and bulkhead fittings for sample line and calibration gas hookups.

GCU-1 and GCU-2 Sample Conditioners

The GCU line of sample conditioners include manual and thermoelectric sample conditioners. The GCU-1 Sample Conditioner includes a probe support adapter panel for stack mount traverse applications and the GCU-2 Sample Conditioner is a stationary assembly for flexible hookup between probe and conditioner. These conditioners include either a 3/8" TFEP Teflon or stainless steel coil condenser, insulated condenser ice bath box, Teflon condensate collection vessel, peristaltic pump for condensate removal and 25' TFEP sample and cal gas umbilical with power and thermocouple distribution box.

Heated Sample Lines

ESC heated sample lines are made in two configurations. The shorter length ESC heated sample lines are available in any length from 5' to 25'. These lines are constructed on a flexible inner sheath that allows the heated Teflon lines to be removable and can accommodate a variety of sizes of Teflon tubing. Each of these lines include a controllable heating grid, a flexible inner sheath, a choice of FEP Teflon removable internal lines, fiberglass insulation and flexible waterproof outer jacket with abrasion resistant expandable oversheath.

The 50' (HH-50-6/4-K) and 100' (HH-100-6/4-K) stock long length heated sample lines are constructed with a constant wattage heater, heated 3/8" Teflon sample line with stainless steel mesh sheath, unheated 1/4" cal gas line with stainless steel mesh sheath, fiberglass insulation and flexible polyurethane outer jacket. The Teflon lines are terminated with 3/8" and 1/4" stainless steel process tube stems. Other lengths and configurations are available by special order.

M5-DC & M5-AC Style Temperature Control Stations

Temperature control stations are available with 1, 2, or 3 analog solid state or programmable digital solid state temperature controllers per station. Each temperature controller within each station is equipped with a 25 amp solid state output relay, a standard 3-prong receptacle per controller and combination mini and standard thermocouple jacks. Each station is further equipped with a 4-pin, 3-circuit amphenol power output jack wired in parallel to the individual 3-prong receptacles, a power control switch and an auxiliary power receptacle. All components are mounted in a weatherproof military style enclosure with a flexible silicone appendage to allow all power and thermocouple hookups to be maintained in foul weather.

Whole Air Sampler, Canisters & Canister Cleaning System

The PWA-100 Portable Whole Air Sampler

The PWA-100 Portable Whole Air Sampler is a mass flow controlled sampler that provides constant flow rate sampling into an evacuated sample canister. Long sampling periods are possible, depending upon the application flow rate and the unit is battery powered for use at remote sites. Ideal for industrial hygiene applications, this compact unit mounts directly to the inlet valve on virtually any size of sample canister and is available with an optional AC adapter and battery charger. Sample canisters are available in 1.8 and 6 liter sizes.

C-9501 AutoPure Canister Purging System

The ESC C-9501 AutoPure Canister Purging System is the most reliable fully automatic 4-canister cleaning system available. Programmable moist, dry and heat cycles, and number of repeat cycles enables the system to be tailored to meet your specific processing and turnaround requirements. The C-9501 standard pump evacuates the canisters to 5 Torr, while the optional C-9501-MD molecular drag pump evacuates the canisters to 10-6 mbar. The high vacuum pump reduces the number of cleaning cycles required to achieve thorough cleaning and provides sample-ready canisters under greater vacuum. The addition of a C-9501-EU 4-Canister Expansion Unit allows 8 canisters to be cleaned simultaneously through the programmed cleaning cycles and automatic operation of the C-9501 host unit.
