Introduction

JCP-300 and JCP-310 portable sample gas conditioning systems are used to reduce the dew point of wet sample gases. They ensure reliable conditioning of sample gases to enhance analysis results. Because water va-pours are suppressed, analyzers can be used in continuous operations with high availability at low maintenance. JCP-300 / JCP-310 sample gas conditioning systems are of modular design and built into a portable housing. The basic unit includes the heat exchanger and a condensate pump for drain. Proven modules are assembled into various instrument versions:

  • Filter element
  • Condensate pump
  • Sample gas pump
  • Temperature display
  • Flow meter with needle valve
  • Condensate detection
  • Stainless steel sample gas inlet
  • Acid dosing
  • Temperature controller for heated sample hose

Function

The portable JCP-300 and JCP-310 sample gas conditioning systems are built in a robust carrying and mobile unit case made of reinforced plastic. All parts needed for operation or maintenance are placed on the front panel. Gas connections are generally on the front panel.

Gas heat exchanger
The JHEX-4 heat exchanger consists of a cylindrical body. The gas flow is designed to bring the wet gas as often as possible in contact with the cooled surfaces. The manner in which the gas circulates causes laminar as well as turbulent flow that enhances the separation of the condensate. The outside of the heat exchanger is thermo-insulated. This prevents the condensation of humid air on the outside of the heat exchanger.

Cooling
For cooling of the gas heat exchanger, Peltier elements are used. This element is mounted in the upper part of the heat exchanger. Due the Peltier effect the sample gas energy is extracted via the heat exchanger and transferred through a heat pipe to the cooling fins. High-volume airflow fans are used for the continuous removal of waste heat to the environment. Sophisticated control electronics provide by means of a temperature sensor a stable dew point.

NOTE
The functions and options described in this chapter are depending on model configuration.

Acid dosing pump
The metering pump is used to add reagents, e.g. phos-phoric acid. The metered addition with the metering pump takes place in front of the first cooling step, to reduce possible, minor elutriation of sulphur dioxide in the sample gas cooler even further.
Pump capacity: 6 ml/h

Condensate removal
To ensure continuous removal of condensate the JCP-300 units are equipped with the JSR-25 condensate pump (approx. capacity 0,30 l/h).

CAUTION!
To avoid leakage of the condensate pump the operating pressure must be between 85 – 220 kPa abs. The tubing of the condensate pump is subject to wear and has to be checked regularly and replaced, if necessary.

Filter element
Fine dust particles are separated from the sample gas by a filter. Filter elements are available in glass fiber or PTFE materials (porosity 2 µm).

CAUTION!!
Stop the sample gas pump before opening the filter housing. Open the filter housing only under pressure-less conditions. The filter element is tight only if the O-ring sea-ling in filter cap is in place.

Sample gas pump
The sample gas pump forwards the sample gas through the gas conditioner to the analyzer. It can be turned on/off via a switch on the front panel. In case of alarm condition, the pump is locked automatically.

Temperature display
To monitor the heat exchanger temperature, the instrument is equipped with a digital display that shows the temperature or an error if the temperature limits are exceeded.

Flow meter with needle valve
To adjust and display the gas flow, the instrument is equipped with a flow meter with an integrated needle valve.

CAUTION!!
Never close the needle valve completely to avoid system damage.

Condensate detection
The built-in electronic module monitors an eventually occurring wet sample gas with the condensate sensor KW1. It turns of the power supply of the sample gas pump. Failure indication is done by color changing of the green status LED “Condensate” to red.

CAUTION!
In case condensate detection occurs, the cause must be corrected immediately. To check or clean the sensor, open the nut and remove the sensor downwards. Equally, dry the gas path downstream the heat exchanger. Check the unit for leaks before starting the op-eration.

CAUTION!
Condensate may contain hazardous substances! Wear appropriate protective clothing!

Stainless steel sample gas inlet
A sample gas inlet of stainless steel SS316 is required to connect a heated sample hose.

Temperature controller for heated sample line
To control a heated sample line the models with large housing can be equipped with a temperature controller.

Startup

  1. Check of the proper installation.

  2. Review the equipment for damage.

  3. Check for leaks.

  4. Check for upright position.

  5. Connect condesate drain and fill acid dosing reservoir with reagent (option).

  6. Set up pneumatic and electrical coonections for heated hose.
    CAUTION! Before switching on the device check rated type plate voltage against line voltage.

  7. Connect power supply. The instrument starts cooling. The fan must run and the Peltier status LED must be illuminated red. The optional” temperature display shows “error 1”. After approx. 15 minutes the operating temperature is reached. The LED colour changes to green and the temperature dis-play shows the actual temperature. As long the Peltier status indicator LED lights up red, the cur-rent cooler temperature is not in the permissible range from 0…10°C. If the Peltier status LED blinks red, a temperature sensor defect is de-tected. After the appliance has reached the oper-ating conditions the gas flow can be introduced.

NOTE
It is possible that there is remaining condensate from the factory test left in the cooler. (water) Keep in mind maximum flow rate of sample gas versus dew point at gas inlet.

CAUTION!
Non-compliance with the control steps can lead to seri-ous hazards or property damage and personal injury!

Operation

With the switch “PUMP” the sample gas pump can be turned on. The needle valve of the flow meter (option) allows regu-lating the sample gas flow.

CAUTION!
Never close the needle valve completely to avoid dama-ges.

Temperature controller heated sample line

General
The controller JPXE-4 can be used in combination with a heated sample gas line with RTD Pt100 or TC NiCrNi (depending on the ordered configuration). If all relevant parameters are stated a used defined configuration may be ordered also. For operation, it might only be necessary to change the set value SV for the temperature. All other parameters stay unchanged for the versions of 115 VAC and 230 VAC supply voltage. If the controller is not preconfigured, you need to define all described parameters and additionally the cycle time. Afterward you need to start Auto-tuning (AT) to calculate the PID parameters.

CAUTION!
Incorrect setup parameters can lead to malfunctions and / or physical damage of the device.
