Seattle, WA, September 15, 2026 – Fathom Water Corporation today announced the commercial launch of the FPC-140, a pre-engineered mechanical vapor recompression (MVR) crystallizer for zero liquid discharge (ZLD) applications. Engineered by Fathom and fabricated in the United States by Samuel EPC, the FPC-140 is delivered to site in under 12 months and ready for commercial operations within 15 months of PO. Traditional, custom-built systems typically complete commissioning 24 or more months after PO.

The crystallizer is historically the most capital-intensive and schedule-critical step in a ZLD system. The FPC-140 removes it as a bottleneck.

The FPC-140 is a forced circulation evaporation process, designed for an evaporation rate of 140 gallons per minute (gpm). Crystallizers at this scale are typically custom-engineered and assembled in the field, exposing projects to budget and schedule risk. However, the FPC-140 is fully pre-engineered with an optimized modular design and manufactured off-site with a compact footprint of ~3,300 square feet.

The base system and its selected options are established before the purchase order is signed. This removes the front-end engineering cycle that drives much of the schedule variability in a conventional crystallizer package, and it means the delivery date is set at award rather than discovered during design.

The FPC-140 is engineered by Fathom with off-site manufacturing by Samuel EPC, a US-based process module fabricator. Fathom and Samuel utilize a module design optimized for total installed cost, moving most man-hours off-site and into the shop. This module design reflects Fathom’s and Samuel’s decades of experience in process module design and fabrication and prepares the installing contractor for success.

Fathom's engineering team has designed, delivered, and commissioned dozens of zero liquid discharge systems across North America, including major projects at HVM semiconductor facilities in Oregon, Arizona, and Texas. Team members bring 20 to 30 years each from industry leaders, such as Siemens, GE, and Veolia. The FPC-140 applies that experience to a standardized system rather than a one-off engineered package.

"Every ZLD project I have worked on over twenty years has had the same conversation," said Nathan Haralson, Founder and CEO of Fathom Water Corporation. "The crystallizer sets the ZLD schedule, and the ZLD is critical path for most projects. We built the FPC-140 so we don’t keep having that conversation. The engineering is finished before the purchase order is signed, ensuring schedule certainty. This is the first in a line of pre-engineered, modular MVR crystallizers."

Fathom builds the system on a domestic-first supply chain of long-standing American suppliers and fabricators, which reduces exposure to tariffs, logistics disruption, and geopolitical risk. For semiconductor fabs and advanced manufacturing projects operating under domestic content expectations, this structure supports both compliance review and schedule certainty.

“Samuel is excited to collaborate with Fathom on the module design and fabrication for the FPC-140,” said Curtis Stanley, President of Fabrication and Construction. “The market has been clear that ZLD project timelines must be accelerated. The FPC-140 will be designed, fabricated, installed, and commissioned through a single partnership between Samuel and Fathom, delivering the project faster and with better quality and execution than traditional ZLD systems.”

The FPC-140 is available for specification and order now. Detailed engineering specifications and process documentation are available to engineering and project teams upon request.
