Safety was a key issue in the running on the tunnel and Zellweger Analytics were contracted to build two sampling systems to be designated northbound and southbound within the underground section of the road tunnel. These would 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 Zellweger custom designed the system, which now effectively monitors the tunnel.
Applications include gas monitoring, hazardous area sampling, chemical processing and use in the printing industry. EX30 pumps are certified to the enlcosure group class IIC and carry ATEX certification allowing use in Hydrogen atmospheres. As an OEM pump it is ideal for monitoring 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 exceed most sampling requirements. |
