MARINI MAC 200 – State of the art Efficiency Delivered

The MARINI MAC Series of hot mix asphalt plants, known for their superior energy efficiency and design have been making waves in recent times. Ramky Infrastructure Ltd, one of the leading infrastructure development companies in the country, has been the latest to experience the immense benefits of the series. Ramky has recently installed the largest plant of their fleet- there are no prizes for guessing - the MARINI MAC 200 for their Moradabad project.


Incidentally, the plant is now known as the greenest asphalt plant installed in North India. Another impressive landmark record that was achieved by Ramky in the project is that the MARINI MAC 200 plant was installed in a record number of hours. The plant, installed by India's leading sustainable development focused company, has been delivered with a host of special features that are aimed at improving productivity and at the same time reduce fuel consumption.

The record time in which the plant was erected and commissioned has come as a pleasant surprise for everyone involved with the project. Said Mr.L.Narayanel, Senior Manager Resources from Ramky, who till now was used to seeing asphalt plants take around 45-60 days to be erected and commissioned in the country, "We erected and commissioned the plant in a record 20 days time. MAC's modular design facilitates quick set-up and owing to the pre-wired and pre-tested units, it was all plug and play, before adding, "All the components fit so well without the need for field modifications. In addition, the plant's control system help diagnose plant problems with ease."

Speaking about the plant, Mr. Y. Nagaraja, Managing Director, Ramky Infrastructure said recently, "Our company is focused on sustainable development and we found in Fayat Group the right partner." The recent addition of Green asphalt plants from MARINI have further fortified Ramky's image in terms of a green company. The management team at Ramky did a thorough analysis of the various aspects before opting for the MAC asphalt plant.

Describing the process of selection of the plant, Mr.Mahendra Kumar VP-SCM, during a meeting with the Fayat team stated "We wanted to graduate and keep our leadership position in the market. India's road construction industry is quite dynamic and the standards are ever-raising. Strategic investment into the right crucial tool like the asphalt plant is therefore a must. We have realized that it is impossible to be profitable without being efficient and green. MARINI MAC featured several energy efficient features and carbon saving technology that we were convinced about the plant being the right tool to keep up with the vision of our company."

Stating his views Mr.Haribabu – VP Transportation, a key member of the decision making team observed, "The decision for MARINI asphalt plants were taken because they have excellent track record in India and abroad. To ensure our bottom lines, we needed our project durations to be shortened, as much as possible. This calls for a highly efficient, productive, and reliable asphalt plant. Once the plant is on project site, project handling, commissioning, and testing procedures need to be done very efficiently to save time. The plant must be bang on the job and produce quality mix, as each day costs the contractor a lot… and that is exactly what MARINI MAC did."

Ramky's MARINI MAC has been supplied with state-of-the-art features. The plant is capable of producing futuristic and low carbon emitting mixes; recycled asphalt mixes with upto 35% RAP content with traditional specification mixes. The plant features dual storage facilities to stock reclaimed filler. This feature was particularly important for Ramky, as they didn't want to have a plant with a top-notch bag filter but then have dust fly all over and around the asphalt plant. A 36 Cbm foreign filler silo with feeding arrang- ement for both filler bags and bulk conveying along with modified bitumen handling tanks come as standard on MARINI plants supplied in India.

This New Generation MARINI plant has been designed to perform at very high efficiency. The plant is configured to work on the highly acclaimed heavy/waste oil firing system of MARINI which helps customers realize huge savings on production costs. The waste heat recovery system, advanced blue flame assisted burner system, highly efficient bitumen heating system, ensure that Ramky's production costs are always unbeatable.

"If something goes wrong, the control system will indicate exactly when a motor came on, the amps it was drawing, and when it was turned off. When you have a problem, this control system saves you a lot of time and trouble. Instead of running around all over the plant trying to see what has gone wrong, you just go to the screen, and the control system will tell you. That way, you know exactly where to start to make the repair." Mr. Soundarraj reiterated the fact that the plant is state of the art, before rounding off saying "It is a great piece of work and is exactly what Ramky wanted."
