Demetrio Velasco, Liquidpulse: Two Megawatt Load Banks, Clean Fluids & Why You Can't Skip Integrated Testing

What if the only way to know your liquid cooling infrastructure will hold up is to make it fail on purpose, before a single rack goes into the white space?

In this episode, Demetrio Velasco of Liquidpulse joins Robert to talk about something the industry has needed for a while: a two-megawatt liquid cooled load simulator capable of stress testing critical cooling infrastructure in a live data centre under real test conditions.

From starting out as a controls engineer building pump and hydronics systems, to launching Liquidpulse out of Dallas and putting liquid cooled load banks into the market at scale, Demetrio brings a manufacturer's view to a commissioning problem that keeps getting bigger.

Together, they explore:

·       Why the jump from a 500kW machine to a two megawatt prototype happened faster than anyone planned

·       How modular, networkable units let teams run tests at 28 megawatts of simultaneous load

·       The origin story: a client with an urgent need, a friend's phone call, and a full witness test where the scope changed at the last minute

·       Why load bank cleanliness matters, and the standard Liquidpulse is pushing at OCP to protect flushed technical cooling systems

·       The air separation problem nobody predicted, and the auto air vent fix that became a second generation feature

·       What integrated testing really proves: the cooling, the medium voltage generation, the power failure recovery modes, and the people commissioning it all

·       The Texas site that skipped integrated commissioning and spent a year working through double digit outages

·       Why a hybrid unit generating 165kW liquid load and 60kW air load exists alongside the 500kW machines
