CPS 450E-125 electric portable air compressor for shotcreting application in highway tunnels

Portable air compressors

Tunnelling our way to reduced travel time!

The prestigious Samruddhi expressway to connect Nagpur with Mumbai, enabling commuters to cover the distance between the two cities in eight hours and transporters in 16 hours, will cut down travel time by almost half. As part of the expressway project, Kasara ghat near Igatpuri, requires tunnels to be constructed at strategic locations to ease travel time.

Eurostar Engineering Pvt. Ltd. as authorised dealers of imported Cifa branded shotcreting machines in India are involved in over 100 tunnel construction projects across India.

As soon as the concrete transit mixer arrives at site, shotcreting needs to start at the earliest where the concrete mixture needs to be sprayed continuously with the help of reliable compressed air. This is crucial so that the RMC (ready mix concrete) retains its original properties and quality.

Eurostar were seeking an electric portable air compressor manufactured in India, with a smaller footprint which could be prefitted on their Cifa shotcreting machines. Another clear focus was on dependable as well as on-time, on-site service, keeping in mind the demanding deadlines of this tunnelling project. Chicago Pneumatic’s CPS450E electric portable air compressor with its compact dimensions fits very well on Cifa shotcreting equipment and with the local authorised dealer reach, service is when and where the customer needs it.

The CPS450E is the ideal compressor model for us as it provides consistent air flow of 450 cfm and 125 psi pressure. This ensures there is uninterrupted spraying of concrete on the wall of the tunnel, ensuring low wastage of concrete.
