Along with this letter I am sending the catalogue which will give details about the equipment of your requirement. All details like important components and pricing are mentioned in the catalogue. The time reuqired for manufacturing the equipment is also mentioned.

       We offer maintenance services required for the maintenance of this equipment. The charges levied for this purpose are also given in the catalogue

      We offer the best prices in the industry and it is our constant endeavour to stay up in the competition. You can compare the existing prices in the market and decide to place an order with us.

    After assessing your requirements if you can contact us, we shall send our representative for completing the formalities. In case you any other special requirements, please let us know so that we can work on that.

  We are looking forward to hearing from you.
