  • Central Utility Plants

    In addition to providing electric, heat, and comfort conditioning to large scale buildings and even entire campuses, many central plants now also provide utilities to vital data centers, life support systems, and other mission-critical applications. It is this demand for uninterrupted service that makes our level of craftsmanship and dependability so valuable to the owner.

  • Power & Co-Generation

    These systems allow our customers to generate several sources of energy utilizing a single fuel source. Typically, a form of fuel gas is utilized to fire a generator which in turn, creates electricity. In addition to this electrical generation, these systems use the “waste” heat created in the process to produce hot water for heating, steam for manufacturing processes, and even chilled water to subsidize their cooling requirements. At the heart of this operation are several pieces of specialized heat transfer equipment, all of which are interconnected through sophisticated, high energy, piping systems.

  • Bulk Storage & Distribution

    The storage and transfer of consumable liquid and gas products is a major aspect of the global economy. These products are stored in large capacity tanks and vessels and conveyed for distribution and use through large diameter piping, high volume pumping stations, and complex manifold systems. In addition to these basic elements, we can also incorporate metering, filtering, and injection systems for accurate blending and manufacturing applications.
