Delta InfraSuite RowCool R Series In-Row Direct Expansion Cooling 30-45 kW. Model RowCool R.

Product Overview

RowCool R series units sit directly between server racks, close to the heat source, as part of Delta’s InfraSuite data center infrastructure. The R-30 delivers 30 kW of cooling from a frame only 300 mm wide (300 x 1090 x 2000 mm, 216 kg), while the R-45 raises capacity to 45.6 kW in a 600 mm-wide frame (600 x 1090 x 2000 mm, 300 kg).

Both units use R410A refrigerant with EC fans and a DC inverter compressor that modulates cooling capacity steplessly from 20 to 100%, matching compressor output to the actual IT load. Local monitoring and configuration are handled through a 10-inch LCD touch panel, and Delta publishes the InfraSuite RowCool DX R-30/45 kW leaflet with full data.

Specifications

RowCool R-30 vs R-45: which frame fits your row?

Both RowCool R models share the same in-row DX architecture; the choice is a power-density calculation. The R-30 delivers 30 kW from a 300 mm-wide frame, the R-45 delivers 45.6 kW from 600 mm. Working figure: a rack at 5 to 8 kW of IT load means one R-30 supports roughly 4 to 6 racks per row segment, while one R-45 covers 6 to 9. Two R-30 frames split across a row often beat one R-45 on airflow distribution, because cooling capacity lands closer to the racks that generate the heat — the shorter the hot-air travel, the less fan energy both the RowCool and the servers consume.

Frame width matters beyond capacity: at 300 mm the R-30 occupies a half-rack position, which matters in leased space or retrofits where every rack unit of white space is billed. If your row already runs dense AI or storage nodes above 10 kW per cabinet, step up to the R-45 or mix both — the series shares the same control philosophy and the same 10-inch touch panel, so mixed fleets stay manageable.

In-row cooling vs room-level precision units: how to choose

RowCool belongs to the in-row cooling class: it sits between cabinets, shortens the air path to under a meter, and captures heat before it mixes into the room. Room-level precision units — such as the Vertiv Liebert CRV CW or the Liebert PEX3 series — condition the whole space instead. The selection logic we use: above roughly 8 to 10 kW per rack, in-row capture wins because room airflow cannot reach the deep rack faces; below 5 kW per rack, room-level units usually deliver the same result with fewer boxes to maintain. Between those bands, either works and the decision comes down to growth plans — in-row scales rack by rack, room-level scales room by room.

Hybrid rows are common in practice: a room-level base system carries the average load while one RowCool absorbs a hot spot where high-density nodes landed. Because the R series modulates steplessly from 20 to 100 percent, it also integrates cleanly with aisle containment — it simply idles when containment and room units carry the load at night.

Deploying RowCool R in an existing row: what to plan for

Three site realities decide installation effort. First, the outdoor cold source: the R series is a DX system, so each unit needs refrigerant piping to a condenser or dry cooler outside the room — plan pipe runs and outdoor unit placement before racking the frame. Second, power and drainage: a 30 to 45 kW DX unit needs a three-phase feed and a condensate drain (or pump-out) at the row, which is straightforward in purpose-built rooms and worth a walk-through in retrofits. Third, containment compatibility: with cold-aisle containment, RowCool discharge is designed to feed the aisle directly; without containment, add blanking panels at minimum, otherwise recirculation erodes the capacity you just paid for.

Frequently Asked Questions

How do I choose the right Delta InfraSuite RowCool for my site?

Consider capacity, site power, environment and monitoring needs. Share your requirements with BS Comtec and we will compare suitable models from multiple brands for you.

Is Delta InfraSuite RowCool compatible with my existing equipment?

Compatibility depends on your electrical infrastructure and connected devices. Our engineers can review your setup and confirm interfaces and integration before you order.

Does BS Comtec ship Delta InfraSuite RowCool internationally?

Yes. BS Comtec ships worldwide and freight options depend on destination, weight and urgency. Contact us for a shipping quote to your location.

What warranty and after-sales support are available for Delta InfraSuite RowCool?

Warranty follows the manufacturer policy for your region, and BS Comtec provides technical documentation and engineer-level support throughout the project.

How many server racks can one RowCool R-30 support?

At a typical 5 to 8 kW per rack, one R-30 (30 kW) carries roughly 4 to 6 racks, and the R-45 covers 6 to 9. The reliable method is to divide total row load by frame capacity and add one frame or about 20 percent headroom for N+1 — hot spots and densification always arrive earlier than the refresh cycle, so sizing to today’s load is the common regret.

Does Delta RowCool R need a raised floor or special room preparation?

No raised floor is required — the unit sits in the row and discharges directly into the cold aisle. What it does need is refrigerant piping to an outdoor condenser or dry cooler, a three-phase power feed at the row, and a condensate drain point. These are standard provisions in purpose-built rooms; in retrofit spaces, plan the pipe route and outdoor unit placement before ordering the frame.
