Gas-Dilution Unit DIL-1/(H) - 1

Gas-Dilution Unit DIL-1/(H) Special Features ■ Proven M&C-dilution technique ■ Operation at ambient temperature ■ Optionally heated to 180 °C (356 °F) or 320 °C (608 °F) ■ Integrated dilution preheater ■ No dew point problems ■ Dilution factor from 10:1 to 500:1 ■ With test gas connection ■ Independent of the ambient temperature ■ Easy maintenance and operation Application The non-heated or electrically heated M&C dilution unit DIL-1 /H is used in analysis technique to dilute the sample gas or components in the sample for example in case of toxic gases, moisture measurement or emission measurement. The M&C dilution unit is based on the functional dilution technique which is proved since years in the M&C gas sample probe SP2000-H/DIL. Description The M&C dilution units DIL-... are mounted on a plate for wall mounting. The version DIL-1 is not heated and works at ambient temperature. The version DIL-1/H is electrically heated up to 180 °C (356 °F). It is additionally equipped with a lagged cover (version for 320 °C (608 °F) on request). A capillary thermostat controlls the temperature, adjustable from 0-180 °C (32 °F to 356 °F). A high temperature limiter and a low temperature alarm is included. The connection of the heated lines is made without cold bridges in the heated part. Before the dilution gas enters the dilution unit, it is heated up to operating temperature via a gas pre-heater. In order to protect the dilution part against contaminations, internal protective filters are installed for the sample gas and the dilution gas stream. Calibration gas can be feeded via the integrated connection. A precision pressure controller with pressure gauge is used for adjustment of the necessary admission pressure of the dilution gas. Via a vacuum pressure gauge, the function of the dilution injector is controlled. Both, pressure controller and pressure gauges have to be ordered separately. Two versions are available: Set -A (-A1) is mounted directly on the mounting plate and control panel type -S (-S1) is suitable for external 19» rack mounting. A shut off valve and a flowmeter for adjustment of the calibration gas are included in the version -S (-S1). The dilution unit can realize dilution ratios of 10:1 to 500:1. In case of high dilution ratios, a respective small quantity of gas is sampled from the process. Optionally a bypass injector -B (Option I) is available integrated right in front of the dilution unit in order to shorten the response time in case of operation with atmospheric pressure or low pressure. In case of option I, an additional pressure controller is included in both mounting versions. The construction of the dilution unit guarantees easy maintenance and operation independent from process temperatures.
