One configuration shown. Every system is engineered to project requirements.

PTU / E-House Modules

Prefabricated electrical infrastructure, engineered and integrated as one system. EN+ designs and integrates modular PTU and E-House solutions incorporating MV/LV distribution, transformers, UPS, controls, protection and auxiliary systems within a factory-built, tested enclosure.

2hr+

Fire-rated structural integrity

2.5MVA

Per-unit transformer capacity

2N

Redundancy options

Built around the electrical architecture.

Every PTU starts with the project's electrical design. EN+ engineers the enclosure, equipment layout and supporting M&E systems around the required voltage levels, equipment, redundancy, fire strategy, maintainability and site constraints.

Equipment from customer-specified or EN+-selected OEMs can be integrated into a coordinated module, assembled and tested under controlled factory conditions before delivery.

Fire Rating 1/2/4 hour fire rating (BS 476 Part 21, 22)
Ingress Protection Up to IP55 ingress protection
Joining Method Easy joining methodology for rapid assembly on site
Shipping Flexibility Semi / complete knock-down arrangement
Paint System ISO 12944 C3-C5 paint system
CoolingHVAC / Ventilation to equipment heat load

Engineered to integrate.

One enclosure. Multiple electrical systems. One coordinated package. EN+ integrates customer-specified and project-selected equipment with the structural, mechanical, electrical, control and safety systems required to create a complete PTU / E-House module.
