Yankee has a wide range of precision measurement tools available for our projects. Our in-house materials testing tools include a Mitutoya surface profilometer and a Caltrex Scientific digital imaging microscope.

Our electronics laboratory is fully equipped with scopes, signal generators, power quality instruments, DC power supplies and a full suite of device programming tools. This group designs and builds custom circuit boards along with microprocessor firmware suitable to each application. Our data acquisition tools include both high-speed and multi-channel (temperature, analog in/out) DAC systems. Most data collection activities involve the implementation and use of a LabVIEW data display and control system.

For many of our programs we design and build custom instrumentation to meet our clients' needs. We have designed and built steam supply systems that can be set up to provide either high pressure or low pressure steam flow to test devices. Yankee has also developed both an orbital and a linear tribometer for evaluating sliding sealing surface wear characteristics in high temperature and pressure environments.

Yankee has developed testing platforms for many heat exchangers, including units designed to work in Organic Rankine Cycle power generators using geothermal energy. In this example, Yankee built and implemented a custom testing platform to transfer heat from a hot brine loop to a refrigerant vaporizing heat exchanger. This unit operated with either R245fa or R134a as the refrigerant working fluid. This system was operated at Yankee's Laboratory to evaluate the performance of the nocel stainless steel 3D printed heat exchangers being developed in Oak Ridge National Laboratory.
