Dos Rios Inc.

Dos Rios Inc. If there is something you need done, give us a call. A fresh perspective, a little hard work, and some fair pricing can't hurt.

2013 was our 25th year of contracting. Things have changed, boomed, busted, and changed again. These cycles have made us pretty adaptable. Currently our gasfield customers are in a depression. Low gas prices ,high costs, and many regulatory burdens are a bad mix.The fun times of ‘just get it done’ have been replaced with canceled projects. During these slower times we have pushed to improve our se

rvices and products. New parts room, altronic repair center, and a clean engine assembly room have been added to the shop. Our crews are the best we have had with long tenure and much experience. Our parts and materials side is greatly expanded. Joe Wolffe has done a great job getting what people need without delay. Providing information and products to meet customers environmental needs has been a priority. The most important thing has been to reduce our customers' operating costs. We have developed a supply network that has allowed great service with very good pricing. If you operate in industrial, agriculture or the oilfield a call to Joe would be worthwhile. Gasfield construction mainly consists of regulatory compliance projects and abandonment operations. We look forward to the economy improving,the sooner the better for all. AGL/Central Valley Gas Storage have contracted us for a good number of projects. CVGS has been a good thing for the area. The construction crews and welders have been doing horse-proof fencing and corral installations as well. Gas compressor fabrication, operation and repairs have been a strong point for DRI. We have represented American Energy Services rental fleet since 1999. We have the parts, men, and experience to take care of almost any compressor or engine project. We are focused on providing the cleanest compressors and service possible. In today's world, nothing else will do. We are working to get into the CNG fueling industry, we are working with a Colusa County start up on planning now. Agriculture diesel engines converted to run on a 30/70 gas fuel mix is a prime project for us. Using the Altronic system, we have seen large savings on fuel costs and lower emissions levels. The pay out has been as short as a month of fuel savings. We can do these projects from the pipeline through the engine.

Our customers hate to see an invoice for us repairing one of our rental units or one of their engines . We hate making repairs and invoices for stupid s### . Two days in a row this engine started and then went down on low engine coolant level . On day 3 Evan remotely locked them out . The well qualified " Operator " called in a "no start problem " . Evan asked for photos . Can anyone spot the handy work repair the " operator " did to take care of the low coolant issue ? Here is a hint , they did not add coolant . Sheesh .
Glad the " Operator " did not burn up the engine . Glad Evan has remote monitoring on the engines , it has saved everyone a lot of trouble and made crops grow to max potential .
