- Appropriation estimates
- Equipment evaluations
- Thermal and mechanical stress analysis
- Equipment and material specifications
ATSI’s mechanical consulting engineers have the ability and flexibility to provide you with varied levels of detail according to your project needs. Experienced designers and drafters proficient in the latest versions of 2-D and 3-D AutoCad and Microstation support our engineers.
ATSI’s design capability is based on solid education, extensive experience in the heavy-industrial sector, and field experience that gives us a competitive edge. Our projects cover a wide spectrum and include the following areas:
- Equipment layout and design
- Material handling equipment design
- Combustion systems
- Emission control systems
- Hydraulic systems and analysis
- Process piping layout and design
- Piping stress and flexibility analysis
- High-temperature refractory design
- HVAC and industrial ventilation design
ATSI’s mechanical consulting engineers consider the construction, operation, and maintenance aspects of a project in order to minimize capital costs and maximize plant availability during operation.

At ATSI, we have developed a reputation for creative problem solving in relation to timesensitive plant shutdown work. We pay particular attention to existing field conditions. This assures the successful installation and start-up of each new system, facility, or piece of equipment. ATSI’s engineers can assist you with activities such as:
- On-site engineering assistance
- Shop inspections
- Installation supervision
- Start-up assistance
- Operation and maintenancemanuals
Thermal Design
ATSI’s mechanical design group specializes in thermal analysis and uses the latest finite-element modeling tools to perform 2-D and 3-D steady-state and transient analyses. We can import results from thermal analyses into our mechanical stress packages to evaluate the effects of high-temperature processes on supporting vessels and structures.
HVAC Design
ATSI has experience in the design of all types of HVAC systems, ranging from small warm air heating installations to computer rooms requiring positive pressurization, air scrubbing and humidity control. ATSI has designed new installations incorporating the latest energysaving concepts and equipment and has handled projects involving renovation of existing equipment in older buildings.
Fluid-Flow Modeling
On more complex piping systems, our engineers will perform flowpath analysis and optimization to enhance system performance. This ensures that system process requirements are met using optimum pumping requirements.
3-D Solid Modeling
ATSI’s designers can perform visualization/presentation, proof of concept, and virtual prototyping of new or existing designs. Working in conjunction with our analytical engineering group, our designers can use finite-element analysis to perform evaluations prior to construction.
ATSI Quality Commitment
ATSI will provide accurate, highquality services tailored to individual project requirements. Our team is an extension of your own staff. ATSI adds value through responsiveness, field experience, and timely technical solutions.
From concept sketches, as-builts, and final design drawings to analyses and project documentation, we emphasize clear presentation of information, accuracy, and close attention to schedules.
