A Unique Application: Newport News Shipbuilding Crane

After 46 years, Virginia’s Newport News Shipbuilding is replacing its gantry crane with a state-of-the-art, 315-metric ton, 241-feet tall electronic model, designed by Kocks Crane, Bremen, Germany. Set to operate 24/7, the crane requires an effective HVAC system, one that can keep the crane’s operational room cold, no matter the outside conditions. The engineer’s choice: CITY MULTI® from METUS, installed by Warwick Mechanical Group, Newport News, Virginia. Warwick has a long-standing relationship with the shipyard and is one of the most experienced VRF mechanical contractors in the state. Selected as the HVAC distributor, APG’s Matt Kemp and Mark Goff speak about the project below and explain why Mitsubishi Electric was the right system for this unique job.

This is a unique application. How did APG get involved and what is the purpose of the crane?

MG: APG was sought out by the engineering firm working on the HVAC design. They were looking to use a Variable Refrigerant Flow (VRF) system due to the simplicity of installation on a ductless system. Essentially, the equipment conditions what you can equate to a giant server room of electronics. The system cools the electronics that operate the entire machine – the crane actually travels down the pier, lifting large sections of the aircraft carrier into place for final assembly.

What specific equipment was installed?

MG: Mitsubishi Electric’s Y-Series was installed. There are two systems – each has an outdoor condensing unit and three indoor units, which are the four-way ceiling cassettes. The cassettes blow the conditioned air in four directions to properly distribute the cooling. The space is not occupied by people generally, but there is a high electrical heat load to account for. In addition, there are thermostats within the space and the AE-200 Centralized Controller. With the Centralized Controller, the entire system can be monitored and adjusted remotely via laptop or desktop.

Why was Mitsubishi Electric the right system for this job?

MK: This project really shows the flexibility of Mitsubishi Electric equipment. We’ve got a remote, mounted condenser in a constantly moving environment. The ability to install the condensers on the legs of the crane and keep them in relatively close distance to the spaces they’re serving just shows that VRF can be effective for a unique, 24/7 operation. We consider this project a critical-cooling application.

MG: If that room was to overheat, the whole crane would shut down – and that’s a problem when you’ve got millions of dollars invested in this type of equipment. Critical is definitely the right word. The technicians at Warwick have my cell number if they experience any issues or run into any problems. At APG, we’re excited about this project and are here to support our clients any way we can.

It’s hard to believe we’re at the end of another year! This holiday season, we at Advanced Products Group (APG) would like to extend sincere thanks to our clients and industry colleagues for a successful 2018. As highlighted in this monthly newsletter, we were busy with a variety of exciting, Variable Refrigerant Flow (VRF) projects and focused heavily on our comprehensive training programs.

This year, we worked on hundreds of projects all over the Washington D.C., Maryland and Virginia areas. Many of the buildings are community establishments including schools, libraries, fire stations, retail venues and churches. We all rely on these buildings every day and APG is proud to serve our local communities in this way.

Technical Training
2018 proved to be another great year for instruction. For the last six years, we’ve offered high-quality, manufacturer-certified technical training on Mitsubishi Electric Trane HVAC US systems. Over the last 12 months, nearly 400 people have participated in our service courses that focus on the CITY MULTI® VRF and M- and P-Series systems. We are here to provide mechanical engineers and HVAC contractors the knowledge they need to exceed their clients’ expectations.

Overall, as we head into the next year, we want to wish you a joyous holiday season filled with rest and good times with friends and family. And be sure to visit us in 2019 for technical training! Our offices will be closed December 24, 25 and January 1.

Product Releases and Recap

We are anticipating exciting new product releases from Mitsubishi Electric in 2019! Below, we share some preliminary details on what’s to come and recap some notable product updates from 2018.
Anticipated Products

N-Generation CITY MULTI®: The Next Generation of the CITY MULTI System will be released in 2019! The system features both increased design and operational flexibility with a smaller unit footprint. A redesigned compressor and fan provides even further reduced sounds and includes five different airflow settings. The system can also be specified in more applications with a broadened range of capacities.

SUZ Universal Outdoor Unit: Part of Mitsubishi Electric’s M-Series product line, the new Universal Outdoor Unit will be able to connect with a variety of indoor units with differing sizes and designs. The flexibility of this unit will be ideal for both performance construction applications and with larger capacity units for light commercial projects.

Product Update Recap

Diamond Controls™ Panel Solutions: These commercially-built, application-specific panels are delivered pre-configured and ready to be installed. This packaged solution approach includes remote access capability and on-site services to reduce set-up costs, streamline startup and maximize user startup. Visit for more information.
ADV-1 Vertical Deflector for PUMY Outdoor Units: The deflector diverts discharge air from a horizontal direction to a vertical direction. This allows outdoor units to be installed closer together without the discharge air from one unit entering into another unit. This offers significant benefit where installation area is limited.
BlueDiamond® Condensate Pump Update: In July 2018, METUS released the following updates regarding this accessory:

  • Exclusive to Mitsubishi Electric, the BlueDiamond Condensate Pump has a five-year product warranty. The standard is three years.
  • BlueDiamond Pumps are now UL Component Recognized instead of UL Listed. This allows all pumps to be produced without a plug, therefore there is no longer a need to remove the plug to wire the units.
  • BlueDiamond Pumps and accessories are now RoHS compliant.

DC-8000 Diamond Controller Release: In July 2018, METUS introduced the new Diamond Controller, a compact, Internet-ready controller and server platform, as part of the Diamond Controls offering. Features include:Built with Niagara4 for optimum performance.

  • Advanced visualization and new search, security and navigation tools.
  • Integration and control of multiple systems within a building, including HVAC, lighting, building IAQ and energy management devices.

The METUS National Account Program

As part of the Mitsubishi Electric Trane HVAC US (METUS) distribution network, Aireco’s Advanced Products Group (APG) is able to provide equipment and support for large brands through Mitsubishi Electric’s National Accounts Program. These exciting projects offer both APG and the selected contractors the opportunity to work with well-known brands, build an even stronger knowledge of Variable Refrigerant Flow (VRF) technology and potentially secure business on multiple job sites.

While there are many benefits to working on one of the National Accounts, each and every client project looks different and has a different project team structure. We spoke with Tom Varga, National Accounts Manager, METUS, who below details the specifics of the program and provides a look into a recent client project.

What is the purpose of the National Accounts Program?

Our group supports the desires of large corporations in multiple vertical markets – such as office buildings, retail and hospitality venues – that are trying to open multiple sites across Mitsubishi Electric’s varying business units. We don’t promote the program, generally clients come to us with a request.

How are the project teams assembled?
Generally, the company will have a developer or general contractor selected. Once they see Mitsubishi Electric VRF is the preferred product, they’ll reach out to me and my partners. From here, things can go several ways: the company will either choose to procure equipment directly from METUS or they’ll want to use one of our distributors. In any case, we rely on our distribution network as well as commercial area and regional managers to find quality and experienced mechanical contractors.

What are the benefits of the program for HVAC contractors?

Typically, the installing HVAC contractor will already have a one-year product warranty for a building after a job completion. That said, it’s an opportunity for the contractor to then start a two- to three-year service contract for each building they work on. It is in the contractor’s interest to become well known to METUS reps and distributors. We tend to do business with and pull teams together from trusted professionals we’ve worked with before.

Spotlight: SunTrust Bank


# of Projects Total: 150+ branches
Project Team for the Purcellville, VA Branch:


SunTrust wanted to standardize a high-efficiency HVAC solution and decided that all of its new branches as well as certain existing locations would have Mitsubishi Electric VRF. The plan included working on 4 – 6 projects per month.

Project Team Setup:

SunTrust chose not to buy equipment directly through us but through a traditional distribution channel – in this case, Aireco APG. Once I got the product specifications and HVAC designs together, I then became their single-source contact for ensuring the project was running smoothly. SunTrust’s facility management partner, Lincoln Harris, was responsible for executing the work.

Once the general contractors were asked to provide a bid and saw Mitsubishi Electric was specified for the job, we needed to pull three to four mechanical contractors in the appropriate business units. We spoke with our area and regional managers and they recommended several qualified contractors for selection. For this project, we specifically chose HVAC contractors who understand our product and the extended 10-year warranty of the equipment.

While the sales process for these types of projects are long-term, VRF is relatively young in this country. The National Account Program helps brands understand and ultimately embrace the technology on a wide scale.
