SUBZERO DATA CENTER ENGINEERING LIMITED
Registration details
Company overview
SUBZERO DATA CENTER ENGINEERING LIMITED is a Private limited company (Ltd.) registered in Ireland under IE563851, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 29 June 2015 and lists its registered address as PARK WEST INDUSTRIAL PARK DUBLIN 12, Ireland. 1 shareholder is on record for SUBZERO DATA CENTER ENGINEERING LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Companies Registration Office (CRO) and was last updated on 27 October 2026.
