WCPS-B – Hawk Water Cooled Packaged Units
(Floor Stand Ducted)

Cooling Capacity from 62 to 1410 MBH (18 to 413 kW)

The WCPS-B features:

• Quiet & High Efficiency Scroll Compressors
• Dunham-Bush Patented Shell & Tube Condenser
• Rigid and Compact Design
• Green Refrigerants

The Dunham Bush Light Commercial Hawk WCPS-B Series bridges the gap between massive central chiller installations and small, inefficient split air conditioners. In typical commercial setups, installing extensive outdoor refrigerant piping or multiple air-cooled split units leads to high electrical bills and messy building aesthetics. The WCPS-B packages the entire refrigeration cycle—the compressors, water-cooled condenser, evaporator coil, and centrifugal blower fan—into a single, compact, indoor vertical floor cabinet.

The core technology relies on premium, low-noise scroll compressors. By running on a non-contact spiral scroll profile, internal mechanical friction is minimized. This design yields exceptionally high volumetric efficiency, smooth gas movement, and minimal vibration signatures, maximizing the operational lifetime of the equipment. For larger capacities, compressors are configured in a shared tandem layout, allowing the unit to scale down its power consumption elegantly during lower building occupancy periods.

To ensure rapid thermal dissipation, the unit incorporates Dunham-Bush's patented cleanable shell-and-tube condenser. Engineered with high-surface-area copper finned tubes and an integrated sub-cooling circuit, it squeezes maximum cooling tonnage out of every kilowatt of energy drawn. Air delivery is driven by double-inlet, double-width AMCA-certified centrifugal blowers that push conditioned air smoothly through extensive overhead duct networks while dampening acoustic feedback.

Key Technical Highlight Matrix

Core Functions of the Dunham Bush Hawk WCPS-B Unit

• All-In-One Indoor Packaging: Houses the refrigeration compressor loop and the primary airside blower assembly together inside a single vertical footprint, eliminating the need for large, exposed rooftop chiller spaces.

• Intelligent Load-Matching Staging: On multi-compressor models (WCPS 220B to 1520B), the system automatically cycles off individual scroll circuits when the indoor temperature stabilizes, preventing unnecessary utility power waste.

• High-Static Air Distribution: The belt-driven centrifugal fans provide excellent external static pressure capability, allowing uniform cooling air to stretch across deep open-plan rooms via standard sheet-metal ducting.

• Acoustic & Thermal Linacoustic Barrier: The cabinet interior is fully lined with high-density linacoustic fiberglass insulation, which absorbs high-frequency motor hums and prevents condensation forming on outer decorative metal panels.

Strategic Importance Across Bangladesh

1. Government Institutes, Public Infrastructure & Defense Assets

State buildings—including administrative auditoriums, municipal digital centers, national archives, and public utility banks—require heavy-duty air circulation and cooling that can be maintained easily without specialized technicians.

• Simplified Maintenance Routines: Because the entire cooling cycle sits inside the room within a single mechanical enclosure, facility operators can easily change filters and test electronics safely indoors.

• Protects Architectural Exteriors: By routing heat rejection through a central water pipe to a single building cooling tower, it removes the need to hang dozens of air-cooled outdoor units on building facades.

2. Private Garment Factories (RMG), Corporate Floors & Supermarkets

For Bangladesh's vital ready-made garment (RMG) factories, private textile floors, massive retail supermarkets, and diagnostics centers, proper temperature control directly dictates worker productivity and equipment safety.

• Maintains High Productivity on the Factory Floor: High-density sewing lines generate massive human and motor heat. The WCPS-B supplies a high volume of uniform, filtered air to keep workers comfortable and minimize heat fatigue.

• Low Operational Downtime Risk: Featuring multiple independent compressor steps, if one circuit requires a filter-drier or expansion sensor change, the secondary scroll lines continue running, preventing total system blackouts.

Frequently Asked Questions (FAQs)

Q1: What does a "Water Cooled Packaged Unit" require to run on site?

Ans: Unlike split units, the WCPS-B Hawk features an internal condenser that must be piped to an external water source—typically a standard outdoor cooling tower loop. It also requires basic electrical line hookups and a duct connection to distribute air into the space.

Q2: Can the shell-and-tube condenser handle hard groundwater scaling?

Ans: Yes. The Dunham Bush patented condenser is fully mechanically cleanable. It features removable water heads, allowing your technical maintenance crew to open the vessel and brush out the copper tubes to clear scaling and maintain peak heat transfer efficiency.

Q3: How does this system handle energy efficiency at partial loads?

Ans: On models with multiple compressors, the system uses progressive step staging. When the indoor thermal load drops (e.g., during night shifts or winter months), the system shuts down unneeded compressors while keeping the remaining lines running at peak efficiency, preventing energy waste.

Q4: Is the fan speed adjustable to match different duct lengths?

Ans: Yes. The WCPS-B uses a belt-driven blower assembly. By adjusting the variable pitch pulleys or changing the belt configuration, our engineering team can adjust the fan speed and static pressure to match your specific ducting layout perfectly.
