  • Refineries and processing plants
  • Biotech
  • Construction
  • Wineries

Urgent response for emergencies:

During the recent Bay Bridge construction, one contractor was using compressed air to drive pylons. The compressor went down, threatening to delay the entire project. We were on site and repaired the unit the same day, keeping the project on schedule.

Napa Valley wineries cannot afford downtime when crushing grapes. Any delay can risk large losses of product. We have field technicians in Santa Rosa and back them with a rental inventory of 100% oil-free air compressors.

Refineries are very sensitive to efficiency and environmental compliance. From supplying dense air injection or powering the whole process, compressed air is vital to operations. Our response is geared specifically for minimizing downtime.

We have the experience:

Our technicians service more than 2,500 contracted units a year. Our history and dedication to customer service has taught us the special considerations needed for the most common applications.

  • Standby power must be 100% reliable. Poor battery maintenance and inspection practices cause most backup power failures.
  • Cogeneration/Combined Heat and Power (CHP) packages have very high initial cost. These units require maximum uptime to achieve positive financial return and environmental benefits.
  • Industrial packages are typically found in chippers, grinders and shredders. Timing engine maintenance with hydraulic and/or mechanical maintenance can yield significant savings. Equipment failure can cause a critical loss of revenue or missing a deadline.
  • Fire pumps protect human life and safety. Failure can quickly turn to tragedy in this highly regulated application. Exact maintenance records must be kept for compliance.
  • Landfill gas power generation requires careful documentation and continual valve adjustments. This application typically has contractual production requirements to power utilities, so service timelines are very tight.

We have earned the trust:

Peterson product support representatives are experienced and provide thorough coverage to our customers. The Peterson way of doing business leads to high levels of employee and customer retention. Our staff have experience throughout California, Oregon and Washington.

Many of our customers came to us because of dissatisfaction with the service they received elsewhere. We keep our word and do not hold back from giving honest evaluations of equipment condition. Few organizations can respond with our speed or quality.

John Muir Health made a substantial investment in the form of Cat cogeneration/CHP units from us. These were installed at a hospital and serviced by supplier with very aggressive rates. Unfortunately their CHP units began to break down due to improper service after only two years. The JMH staff reached out to Peterson; we were able to repair all their units, and then we installed remote monitoring to reduce future downtime.

Emissions Service

Technology to Stay in Compliance

Diesel Particulate Filters
A Diesel Particulate Filter is a filtration system designed to reduce particulate, carbon monoxide and hydrocarbon emissions. This solution can bring existing CAT 3400, 3500 and 3600 Series diesel engines into regulatory compliance.

A series of alternately blocked channels forces the exhaust gas to flow through the channel walls, where the particulates are physically captured and chemical reactions take place. Carbon monoxide and hydrocarbons are converted into carbon dioxide and water. Backpressure is reduced through a process called passive regeneration that automatically removes excess particulate matter.

  • Particulate reduction greater than 85%*
  • Carbon monoxide reduction greater than 90%*
  • Hydrocarbon reduction greater than 90%*
  • Diagnostic module for backpressure and exhaust temperature
  • Backpressure less than 18 of water (critical grade silencer)
  • Alarm notification for high pressure levels

* When properly sized, clean, operating about 300°C and using ultra low sulfur diesel fuel.

Oxidation Catalysts
Oxidation Catalysts help lower engine emissions through chemical reactions that convert carbon monoxide, hydrocarbons and aldehydes into carbon dioxide and water.

A Catalytic assembly-available to suit many machine applications – is installed in place of the standard muffler. Exhaust flows through a steel housing with a specially formulated catalyst. Here, chemical reactions work to minimize machine emissions.

  • Carbon monoxide reduction up to 85 percent in engines up to 750 horsepower
  • Hydrocarbon reduction up to 60 percent
  • Particulate matter reduction up to 20 percent

Selective Catalytic Reduction
Selective Catalytic Reduction effectively removes most nitrogen oxide emissions (NOx) from engines. For CAT 3400, 3500 and 3600 Series stationary gas and diesel engines, Selective Catalytic Reduction is the most durable and reliable process to reduce NOx. This is the only aftertreatment effective for reducing NOx.

The process eliminates more than 90% of NOx emissions by injecting urea, a non-hazardous solution, into the exhaust system. At temperatures above 300°C, urea decomposes to form nitrogen and water, eliminating most exhaust emissions in the process.

  • NOx reduction greater than 90% in open loop system
  • NOx reduction greater than 95% in closed loop system
  • Continuous monitoring of atmospheric conditions and engine parameters
  • Caterpillar Warranty of one year or 8,000 hours of operation from time of sale
  • Optimum product support and system integration provided by your CAT dealer
  • Stainless steel construction for longer life
  • Limited maintenance coincides with regular engine maintenance

SOS Fluid Analysis

Protect Your Investment

Imagine if there was a way to monitor the internal health of your heavy equipment without tearing the machine down to its basic components? There is, and it’s called SOS Fluid Analysis!

Peterson’s Fluid Analysis Lab in Eugene, Oregon specializes in analyzing fluids from your equipment fleet and examining those fluids for common signs of component failure. For example, the occurrence of fine metal particles in hydraulic oil often indicates the breakdown of a hydraulic pump or another major component. If these particles are detected early enough, service technicians can replace the pump and oil and prevent further damage to the entire hydraulic system.

Fluid Analysis does far more than discover component failures, though. It’s also the best way to gauge when to replace the fluids in your machine. Broken down oil, or oil containing contaminants such as water, could lead to overheating and excessive wear of important machine components, damage that can be prevented by keeping tabs on the condition of your fluids through our analysis.

Peterson is committed to your machine’s long-term reliability, and fluid analysis is just one of the ways our highly trained staff uses technology to deliver you a quality service experience.
