"Trinidad Engineering, Inc provided us with energy conservation, troubleshooting and engineering design services. As part of their services they helped us evaluate the replacement or modification of several major pieces of equipment Trinidad's work was thorough and accurate. The equipment they recommended and helped start up has proven to be reliable. It has met all our expectations. Trinidad was especially helpful in identifying utility rebates and financial returns for the new installations.

I would not hesitate to use or recommend their services. "

  Project 1 - Refrigeration Engineering and Construction Administration
Client - L. Knife and Son, Kingston MA,
Date - 1998 to Present

For over three years we have provided refrigeration engineering and consulting services to the following wholesale beer distributors; L. Knife and Son, Seaboard Products, Union Beer and Try Valley. At L. Knife and Son, we provided engineering drawings and consulting services to expand their warehouse by 33,000 square feet. The design involved carefully modeling their cooling load and equipment performance. What made this warehouse unique was that they change the warehouse temperatures each month. The coldest set point occurs in January. The warmest occurs in August. The temperature in the warehouse swings from 40 F in the winter to 65 F in the summer. We modeled these swings with the incoming beer load and stacking practices and found the peak loads do not occur in the summer when the highest beer shipments and temperatures occur. The highest loads actually occurred in the spring and the fall. This evaluation caused us to recommend different equipment sizes and head pressure controls than previously used. Once the equipment was selected, we could model its performance on our computers before it was installed.

Project 2
- Energy Conservation and Controls Engineering
Client - ISP Freetown Fine Chemicals, Assonet, MA
Date - 2001 to Present

We currently provide ISP with ongoing industrial engineering and efficiency improvement services. Our previous recommendations resolved control and pumping problems for this 115,000 square foot chemical manufacturing facility. We were initially brought in by the local electric utility to help their customer reduce operating costs. During a free, preliminary walkthrough, we identified eight potential opportunities. We were then contracted to do engineering evaluations on the potential energy savings, engineering feasibility and utility rebate incentives. Part of our proposal included using ultrasonic flow meters to measure process water flows and electrical measurements. The results were recommendations that reduced operating costs by 5 % with a 3-year payback.

Currently we are assisting ISP with a 500 ton, 14 F glycol chiller replacement and process cooling tower replacement. This investigation required us to build a custom data collection panel which measures and data logs process temperatures and pump head pressures. Approximately 1000 hours of data was collected. This data was useful in several ways. It is being used to optimize chiller selection and controls. It also revealed process-pumping problems with the main circulating and chiller pumps. Both sets are cavitating during maximum flow. This condition has existed since 1978, which is when the pumps were installed. Until we did the data collection, ISP did not know why they lost cooling and therefore several product batches.

Project 3 - HVAC Engineering and Troubleshooting
Client - Deaconess-Waltham Hospital
Date - 2001 to 2002

We sucessfully provided the hospital and its contractors with engineering design and troubleshooting services to resolve problems with their high-pressure steam boilers. The boilers were used to provide all the hospital's sterilizers with steam. Steam is generated off four boilers and sent to the central processing center and the operating rooms. For two years the boilers were continually shutting down on low water, the steam was wet and the steam pipes were corroding. After carefully evaluating the system and reviewing the work done by previous consultants, we recommended changes to the DA tank controls, added conductivity controls, re-engineered the boiler feed system and re-designed the steam and condensate return system. This solved the boiler shut downs and the wet steam.

The corrosion problem was solved by carefully monitoring the steam and boiler water's chemcial properties. The operation of the boilers and sterilizers results in many hours of no steam flow. However steam remains in the pipe and condenses. Because there is no flow, the amine, which is used to treat pipe corrosion, falls out of the steam before the steam reaches the end of the steam pipe. The solution was found to be a blended amine. We also discovered the chemical pump's setting proved to be very critial in boilers with small water contents. Too much chemical would cause boiler water contaminates to be carried over because of rapid boiling. Too little chemcial would result in pipe corrosion. In either case, the contaminates would travel through the piping system and be depositited into the sterilizer chamber. This essentially made the steril operating instruments useless.

Once the chemical and mechanical problems were fixed, the sterilizers worked properly from that point on.
