Read MoreGrowth in 2017: New hires for all trades at DesignTech
Since the start of the year, we have been adding depth to the roster! In the first half of the year, our Leesburg, Virginia office added additional staff in the electrical and plumbing engineering departments. Ken Poulter and Jhonny Suarez Diaz have added a great amount of experience and training to the company as well as a great culture of excellence in their work.
Ken has over 30 years of experience in the plumbing engineering field; including over 20 years as a studio director and/or plumbing department head. In addition to design expertise of sanitary, water, natural gas, and medical/compressed air systems, his experience has provided him with extensive multi-disciplinary exposure and building code knowledge. He serves with DesignTech as a plumbing designer, project manager, quality control resource, and business development team member. His responsibilities also include development of project specifications and construction administration.
Jhonny has fourteen years of experience in the Electrical Engineering field as both a master electrician and electrical engineer. His experience has provided him extensive knowledge of the National Electrical Code, electrical installations and maintenance, and project troubleshooting. In addition, he has specific experience with development and implementation of method of procedure (MOP) protocols, and assessment of mission-critical infrastructure systems for safeguarding data center uptime. His skills also include assessment of energy consumption for periodic efficiency figures (PUE) as well as whole project data. His responsibilities at DesignTech include building site visits, investigative reports, project engineering, construction administration, development of specifications, cost estimates, and lighting calculations.
Most recently, Ross Lynam has joined our Kensington, MD office as a mechanical engineer. Ross graduated this year from Penn. State University with a Bachelor of Science in Mechanical Engineering. Ross has already worked on several projects in both the private and public sector and is poised to become a more independent project engineer with each project he has under his belt.

Sparta, Wisconsin: Modular Chiller Witness Test
This past Tuesday, DesignTech participated in the witness test and demonstration of the modular chillers for an undisclosed interiors project in Washington, DC. DesignTech served as the owner's representative; verifying that the system met the design specifications. The test took place in Sparta, Wisconsin at the Multistack chiller manufacturing facility.
The manufacturer demonstrated the proper operation and startup of the eleven chiller modules and two end suction chilled water pumps. The Multistack facility in-house tests their equipment with a hydronic system capable of testing three of the 30-ton modules at once. The performance testing was completed successfully; with each module proving the nameplate data to be accurate. The chillers were specified with complete factory controls that were complete at the time of the testing. The completion of the controls installation allowed the factory to demonstrate the sequences of normal operation as well as a myriad of failure condition responses including but not limited to:
- Power source out of phase
- Circuit failure(s)
- High head pressure condition at compressor
- Loss of flow to module
- Loss of leaving chilled water temperature sensor input (fail to run sequence)
- Loss of pump drive control
- Primary chilled water pump failure
Multistack did an excellent job in their demonstration and their product line is a testament to their willingness to customize equipment for specialized applications. Stay tuned for to see this modular chiller at work once it is shipped to Washington, D.C.
