About Cypress Envirosystems

We transform existing facilities into smart, connected environments using Non-Invasive Digital Overlay™ technologies—in 10 minutes or less

 



Our Mission: Smarter Facilities, Zero Disruption

The world’s infrastructure is aging. Most operational facilities—from hospitals to nuclear power plants—were built decades ago, relying on mechanical, analog, and pneumatic systems. These “dumb” systems are isolated, labor-intensive, and energy-inefficient.

Traditionally, upgrading to smart technology meant lengthy engineering reviews, costly downtime, cutting pipes and running wires. The disruption often cost more than the upgrade itself, leaving critical facilities stuck in the past. Cypress Envirosystems changes the equation.


Our Technology: Non-Invasive Digital Overlay™

We don’t replace your existing infrastructure; we make it smarter. Our patented Digital Overlay technologies are non-invasive solutions that install directly over your existing instrumentation.

  • Fast Installation: Most solutions install in under 10 minutes.
  • Non-Invasive: No cutting pipes, no running wires, no leak checks.
  • Cost-Effective: A fraction of the cost of traditional retrofits with a rapid payback period.

 

By digitizing analog data, we empower facility managers to automate fault detection, improve uptime, reduce energy waste, and ensure worker safety.
