Dunham Bush Water Cooled Chiller WCFX Series

The primary function of the Dunham Bush WCFX Series Chiller is to continually generate high-capacity chilled water for large-scale central air-conditioning networks and thermal industrial processes. Utilizing a heavy-duty flooded refrigeration cycle, the system extracts heat from a facility's internal space and transfers it out through a cleanable shell-and-tube condenser linked to an outdoor cooling tower loop.

The WCFX lineup is engineered into two primary technological configurations to match your facility's energy targets:

• WCFX-E Series (Standard Premium): Equipped with ultra-quiet, high-rigidity vertical rotary screw compressors and advanced flooded evaporators to lock down premium full-load thermodynamic efficiency.

• WCFX-V Series (Variable Frequency Drive): Features an integrated, inverter-driven VFD compressor. This variant is explicitly optimized for green building designs where partial load demands fluctuate, allowing the motor to slow down and save immense power during rainy or winter cycles.

Importance of This Product Across Key Sectors in Bangladesh

1. Government Institutes & Strategic State Facilities

State-funded infrastructure—such as national data centers, public medical colleges, international secretariats, and multi-terminal airport zones—demands unwavering stability, high safety standards, and strict compliance with national energy guidelines.

• Certified Power Compliance: The WCFX series is fully AHRI certified (Standard 550-590) and strictly meets ASHRAE Standard 90.1 efficiency codes, ensuring state-operated plants cleanly clear green building and sustainability audits.

• Advanced Logic Protection: Outfitted with the patented Advanced Vision Controller or DB Director, the system features a vivid color touch screen display. This allows maintenance crews to quickly spot voltage phases, track real-time telemetry, and integrate smoothly with centralized Building Management Systems (BMS).

2. Private Manufacturing, RMG Megamills & Pharmaceuticals

For continuous-production facilities—such as massive Ready-Made Garments (RMG) factories in Gazipur, textile spinning centers in Narayanganj, and sterile pharmaceutical cleanrooms in Savar—unstable temperature directly ruins raw materials.

• Redundancy Protection: WCFX models can be selected with single, dual, or triple independent compressor circuits. If one circuit undergoes routine cleaning or maintenance, the other circuits pick up the building load smoothly, preventing sudden plant downtime.

• Cleanable Mechanical Maintenance: Bangladesh’s local factory water sources often carry mineral compounds that cause scaling. The WCFX flooded shell-and-tube design features removable liquid heads with straight-through copper tube access, allowing technicians to mechanically clean the tubes without tearing down the structural layout.

Frequently Asked Questions (FAQs)

Q1: What are the main benefits of the vertical screw compressor used in the WCFX series?

Ans: Dunham Bush's proprietary vertical rotary screw compressors offer fewer moving components than traditional reciprocating or horizontal configurations, resulting in inherently lower internal vibration profiles, premium reliability, and noticeably quieter operations.

Q2: Can the WCFX chiller handle variable water flow rates?

Ans: The WCFX series is engineered to perform exceptionally well under steady water conditions. While it safely handles moderate flow deviations ($\pm10\%$), highly erratic water variations can disrupt internal temperature tuning; therefore, proper secondary loop balancing is always recommended.

Q3: Is a split-design configuration available for tight entry rooms?

Ans: Yes! The intelligent side-by-side arrangement of the evaporator and condenser shells allows for an optional factory-split layout. This makes it significantly easier to maneuver the modules through standard commercial doors or elevators without breaking down structural wall frames.

Q4: What eco-friendly refrigerants does this series run on?

Ans: To support long-term green building compliance, the WCFX series utilizes eco-conscious refrigerants such as R134a and low-GWP R513A, ensuring zero ozone depletion potential.
