RACK MOUNTED PRECISION COOLING

The HSI Series rack-mounted precision air conditioner slides into the base of a standard 19-inch cabinet and cools the rack from within — no separate floor space needed.

It handles single-cabinet heat loads up to 15 kW, holding precise, stable temperatures for high-density racks, edge sites and small server rooms.

The indoor unit plugs in like any rack appliance, with the outdoor unit and refrigerant module integrated for a quick, simple install.

Key capabilities.

• Air-cooled, integrated outdoor unit

• Fits standard 19" cabinets (5U–10U)

• Plug-in install, auto-restart

Why it wins?

• Single-cabinet cooling :4–15 kW right where the heat is, inside the rack.

• Fast, simple install :Slides into the cabinet base; quick-connect lines.

• Precise control : DC inverter compressor and PID keep temperatures stable.

• Smart & efficient : Remote monitoring; EC fan; efficient part-load operation.

Where you'd use it

• Growing server rooms : Add cooling in step with new cabinets, row by row.

• Modular & prefab data centers : Cooling for single- and dual-row contained aisles.

• High-density racks : Densities that overwhelm conventional room cooling.

• Colocation halls : Predictable, per-row cooling for mixed tenants.

Questions, answered

• How is it different from room AC? — It cools inside the cabinet, at the rack, so a single high-density rack stays cool without          flooding the whole room.

• Is it hard to install?— No- the indoor unit slides into the cabinet base and plugs in; the outdoor unit is one integrated body.

• How much can one unit handle? — Up to 15 kW per cabinet, across four models (4 / 8 / 12 / 15 kW).

• How do we manage it? — Remote monitoring over standard comms, with auto-restart and simple factory presets.
