Explosions proof Pumps specified in the major tunnel transport project.

Charles Austen pumps EX30 explosion proof pumps were chosen for their reliability, robust construction and ATEX certification by a leading manufacturer of gas analytics to be incorporated in an aspirated gas sampling systems for a major tunnel transport project.

Analysis found that the tunnel was handling two thirds of all sea port trade and sees over 2 Million trucks and 300,000 cars travel in and out of the port each year. These figures have been growing steadily and the cities roads were not able to keep up.

The solution has been the tunnel which comprises 5.6 Km of dual carriageway, 4.5km of which is 20m beneath the city.

Safety was a key issue in the running of the tunnel and the leading analytic company were contracted to build two sampling systems to be designated northbound and southbound within underground within the underground section of the road tunnel. These monitor two storm water sumps and the O2 levels in the air eliminating the possibility of explosions from petrol and oil spillages and health risks from the possible rise in carbon monoxide. Using six EX30 pumps to service 24 sampling points with their custom design system, which now effectively monitors the tunnel.

EX30 pumps are certified to the enclosure group class IIC and carry ATEX certifications allowing use in Hydrogen atmospheres. As an OEM pump it is ideal for monitoring hazardous atmospheres including the ingress of flammable gas and smoke into HVAC ducts. With a standard performance of 17 l/min flow, 2.8 bar pressure and 540 mmHg vacuum the standard pump will far exceed most sampling requirements.

Application ideas include gas monitoring, hazardous are sampling, chemical processing and use in the print industry.
