Rosemount™370XA Enclosure

Natural Gas Chromatographs are often

used in isolated locations for custody

transfer applications. This can leave the gas

chromatograph vulnerable to tampering and the

gas canisters susceptible to theft. In addition to

isolated locations, the gas chromatograph and

its sampling handling system can be exposed

to extreme environmental conditions. These

conditions may allow the gas in the sample

system to fall below the Hydrocarbon Dew Point

of the gas, causing liquid fallout and inaccurate

flow measurements.

An insulated clamshell enclosure for the gas chromatograph

and a small calibration gas cylinder provides protection from

intrusion from un-authorized third parties and theft with

its lead-seal feature. An optional heater ensures an ambient

environment of 68 °F (20 °C) when outside temperatures drop

to -4 °F (-20 °C), keeping the gas above its Hydrocarbon Dew

Point.

Features

The enclosure meets CSA Class I, Division 1 certification and is

easy to use. The enclosure comes with the gas chromatograph

prewired to an external Class I, Division 1 junction box, reducing

the complexity of installation and saving you time and costs.

Designed for Extreme Environments

„

UV, sea-water and fungi resistance

„

Ability to lock and lead-seal the enclosure to prevent

unauthorized 3rd party access

Reduced Installation Costs

„

Small, composite clamshell replaces the need for a

conventional single room or dual room analyzer building

that is cost prohibitive for lower volume applications

„

Enclosure enables locating the Rosemount 370XA Gas

Chromatograph close to the sample point, shortening the

heated sample lines

„

Internal tubing and wiring plumbed and connected to the

Rosemount 370XA Gas Chromatograph before arriving in

the field for easier and quicker field installation

Ease of Use

„

No need to remove the Rosemount 370XA Gas

Chromatograph from the enclosure to perform routine

maintenance as the enclosure is designed with sufficient

space and big hands in mind

„

Enclosure’s clamshell lid with stainless steel lid stays and

spring loaded retainer chains is easy to lift yet will not close

accidentally for increased safety

„

Heat-trace boot entry tubing for sample gas ensures thermal

stability to keep the gas sufficiently above its Hydrocarbon

Dew Point of the gases to avoid liquid fallout
