Direct Expansion Coil in West Bengal

Konark India Engineering is a reliable Direct Expansion Coil Manufacturer and Supplier in West Bengal, providing refrigerant-based cooling coils for HVAC, air-conditioning, refrigeration, commercial, industrial, and specialized cooling applications.

A Direct Expansion Coil, also known as a DX Cooling Coil, is a heat exchanger in which refrigerant evaporates directly inside the coil tubes to absorb heat from the air passing over the coil surface. This direct refrigerant cooling process is widely used in air-conditioning and refrigeration systems where the refrigerant is supplied directly to the evaporator coil.

Our Direct Expansion Coils can be designed and supplied according to the required airflow, cooling capacity, refrigerant system, coil dimensions, number of rows, fin spacing, tube arrangement, refrigerant circuiting, and equipment configuration.

Direct Expansion Coils may be used in:

• AHU and air-handling systems
• FCU and zone-based cooling systems
• Packaged air-conditioning systems
• Commercial HVAC systems
• Industrial cooling applications
• Refrigeration systems
• OEM equipment
• Replacement cooling coil applications

 

We support HVAC contractors, MEP consultants, OEMs, facility managers, industrial buyers, project developers, and procurement teams with standard and customized cooling coil requirements.

Direct Expansion Coil for Refrigerant-Based Air Cooling

A Direct Expansion Coil cools air by allowing refrigerant to evaporate directly inside the coil tubes.

During operation, warm air passes over the coil surface while refrigerant inside the tubes absorbs heat from the air. The refrigerant changes state during the heat-transfer process, allowing the air temperature to reduce before it is supplied to the required space.

Direct Expansion Coils may support:

• Direct refrigerant-based air cooling
• HVAC air-conditioning
• Air handling systems
• Packaged cooling systems
• Commercial cooling
• Industrial process cooling
• Temperature-controlled environments

The actual cooling performance depends on the refrigerant, airflow, coil design, operating temperatures, circuiting, and overall refrigeration system.

How Does a Direct Expansion Coil Work?

A Direct Expansion Coil transfers heat from air to refrigerant flowing through the coil.

• Warm Air Enters: Air passes over the DX Cooling Coil surface.
• Refrigerant Flows: Refrigerant enters the internal tube circuits.
• Heat Transfer Takes Place: Heat from the air is transferred to the refrigerant.
• Refrigerant Evaporates: The refrigerant absorbs heat and evaporates as part of the refrigeration cycle.
• Cooled Air Leaves: The cooled air continues through the HVAC system and is supplied to the required area.

The actual cooling performance depends on the coil design, airflow, refrigerant conditions, coil surface area, and refrigeration system operation.
