Delta B Series Air-Cooled Computer Room Precision Air Conditioner For Data Center. Model B Series.

Product Overview

The Delta B Series series delivers kW of precision cooling for mission-critical IT and telecom environments where temperature stability directly affects equipment uptime and operating cost.

Why Precision Cooling Matters in Real Deployments

Consider a 200 m² edge data center processing payment authorization for an entire city. If the room drifts to 28°C, server fans ramp up, MTBF drops by 40%, and PUE climbs above 1.6 — pushing electricity costs 30% above projection. The Delta B Series prevents this cascade. It is engineered for:

• Edge and mid-size data centers (50–500 m²) requiring close-coupled cooling at rack level
• Telecom switching rooms where 24/7 operation is mandated by service-level agreements
• Medical imaging rooms (CT, MRI control rooms) where temperature stability protects calibration accuracy
• Industrial control cabinets in semiconductor fabs and pharmaceutical clean rooms

What Distinguishes the Delta B Series from Generic HVAC Systems

Most comfort air conditioners claim to handle server-room heat loads, but only precision cooling units deliver the control tolerances that IT equipment actually requires:

1. Tight temperature control (typically ±1°C around setpoint, vs ±3°C for comfort HVAC) — critical for ASHRAE Class A1 environments
2. Integrated humidity management (active dehumidification and humidification to maintain 40–55% RH) — prevents static discharge and corrosion
3. Hot-aisle / cold-aisle compatible airflow (front intake, rear exhaust at controlled CFM) — eliminates bypass air that wastes cooling capacity
4. Year-round operation without free-cooling freeze risk (low-ambient kits for cold climates and economizer integration)

Buyer’s Question: What Capacity Do I Need?

General sizing for a precision cooling unit:

• 1 rack (5 kW load) → choose a 7–10 kW unit (1.4× headroom for redundancy)
• 4 racks (20 kW load) → choose a 25–30 kW unit
• 10 racks (50 kW load) → choose a 60–70 kW unit, plan for N+1 redundancy with two units

Add 20–30% headroom for future rack density growth. If your racks include GPU servers (AI workloads), plan for 2× inrush heat-load.

Cooling Architecture Options

The Delta B Series family supports three architectures:

• Row-level (in-row) cooling — placed between server racks, ideal for hot-aisle/cold-aisle containment
• Per-room (CRAC) cooling — perimeter placement with raised-floor or overhead duct distribution
• Rack-mounted (in-rack) cooling — for high-density single racks (15–30 kW per rack)

Integration with Building Management

Standard RS-485 / Modbus connectivity integrates directly with BMS platforms. SNMP option enables remote monitoring via DCIM tools. The Delta B Series supports group control for N+1 redundant operation.
