Phase One: 1,200 Square Feet and New Cooling Capacity

Helixrack completed its first facility expansion on May 7, 2023. The original 300-square-foot room was joined to an adjacent 900-square-foot unit, bringing the Elizabeth operation to 1,200 square feet. The work added cooling, a new electrical panel, four production racks, and a larger protected-power system.

The expansion created room to operate. It did not make every square foot, rack unit, or theoretical kilovolt-ampere available for sale.

More floor, one operating envelope

The added unit provided a better base for equipment rows and airflow than the first room. Helixrack treated the combined space as one facility with a shared capacity plan rather than two independent rooms. Equipment location had to account for supply air, hot exhaust, service clearance, cable paths, and the ability to move a server without disturbing its neighbors.

A 5-ton mini-split became the first dedicated production cooling unit. “Five ton” is the equipment’s nominal cooling class, not a guarantee of usable IT load. Outdoor conditions, line-set installation, indoor airflow, sensible heat ratio, filtration, maintenance, and where air reaches the rack all affect performance. Temperature observations and alarms therefore remained part of the capacity decision.

Theoretical power versus usable power

The new panel was described as 60A, three-phase, 208V. The standard three-phase calculation—voltage × current × √3—produces about 21.6kVA of theoretical apparent power at the panel rating.

That number is not the safe continuous IT capacity. Continuous-load rules, phase balance, power factor, protective-device ratings, distribution losses, redundancy targets, cooling capacity, and operating headroom all reduce the usable envelope. Helixrack did not convert 21.6kVA directly into a promise of 21.6kW for customer equipment.

The April 29 load alert reinforced the point. New branch capacity had to be distributed and monitored, with a conservative allocation target on each circuit. A rack position was usable only when power, cooling, network, and response capacity were available together.

Five production racks, 20U occupied

Four racks were added from inspected inventory. Together with the repaired Helix Rack, they brought the production total to five. The original two-post frame remained a separate receiving and burn-in bench and is not counted as a production rack.

At completion, the inventory records 20U occupied. The larger amount of empty rail space was not the same as marketable capacity: some positions were reserved for switching and power distribution, some lacked an approved power assignment, and some depended on cooling observations that had not yet been collected.

The date lock matters for any image of this milestone. A correct scene may show five production racks, one mini-split, the original room, and the adjacent space. It must not show the later generator, second HVAC unit, garage expansion, 16- or 22-rack layouts, or current network equipment.

A 30kVA protected-power bus

The expansion also brought a refurbished 30kVA double-conversion UPS into service on the protected IT bus. It was inspected and integrated as facility equipment, with actual runtime depending on connected load and battery condition. The original 1500VA UPS was reassigned to network and control equipment only.

The 30kVA unit provided ride-through; it did not provide indefinite backup generation. A generator and automatic transfer system came later. At this milestone, a long utility interruption could still exceed stored-energy capacity.

Phase One was complete when the new space could be operated as a controlled system, not when every rail was filled. It gave Helixrack the next unit of growth and, equally important, clearer limits on what could be installed safely.
