About us

Factory-built electrical rooms, engineered for real project delivery.

EHOUSE designs and builds modular electrical rooms for industrial power distribution, MV drives, automation, process safety, BESS, EMS and low-voltage control systems.

Our work focuses on moving risk out of the site and into a controlled factory environment: structure, equipment layout, HVAC, cable routing, fire protection, FAT/SAT documentation and delivery interfaces are coordinated before shipment.

Energy as a Service

From equipment purchase to measured energy-saving retrofit.

Owners do not need only another electrical supply package. They need a retrofit that can be approved with a clear business case, installed within a controlled outage window, measured transparently after commissioning and supported through long-term operation.

EHOUSE EaaS converts MV auxiliary-load retrofit into one structured program: modular MV Drive E-House, EMS measurement, commissioning, lifecycle service and savings review are managed together.

3D SIS process safety architecture with safety trip path and BPCS monitoring path Certified SIS

Market message

Detect, decide and drive the process to a safe state.

A modern SIS helps detect hazardous process conditions, execute verified safety logic and isolate equipment through ESD valves, pump trips, alarms and safe-state actions. The safety layer remains independent from normal process control while sharing operating visibility with BPCS/HMI where appropriate.

  • SIL 2 / SIL 3 oriented architecture for process and hybrid safety applications.
  • Redundant, high-availability safety control with failover and diagnostics.
  • Lifecycle support for SIF definition, SIL targets, cause-and-effect matrix, FAT/SAT and change management.

01

Independent Protection Layer

Separate safety trip paths reduce common-cause risk and keep critical SIF execution distinct from normal BPCS control.

02

High Availability

Redundancy, failover and diagnostics help protect uptime while maintaining safety integrity for critical process assets.

03

Compliance Evidence

Documentation supports IEC 61511 / IEC 61508 style lifecycle activities including SIL targets, LOPA, verification and proof-test planning.
