V Type Dry Cooler
Thermocore V type dry coolers are designed for HVAC systems, industrial process cooling, data center free cooling, closed-loop glycol systems, compressor cooling and manufacturing facilities where reliable air-cooled heat rejection and low water consumption are important.
The V-shaped coil arrangement provides large heat transfer surface area within a compact footprint. Process fluid or glycol remains inside the finned tube coils, while axial fans move ambient air across the coil banks to reject heat without an open evaporative water loop during standard dry operation.
Product Overview
V Type Dry Cooler Overview
A V type dry cooler is an air-cooled heat exchanger that uses V-shaped finned tube coils and axial fans to reject heat from a closed fluid loop. The process fluid stays inside the coil, while ambient air flows across the external fin surface. Heat is rejected to the air by sensible heat transfer rather than open evaporative cooling.
This product is suitable for projects that need low water consumption, closed-loop fluid protection, simple outdoor operation, free cooling potential and reduced water treatment requirements compared with open cooling towers.

Working Principle
How Does a V Type Dry Cooler Work?
The system rejects heat through dry air cooling. Hot fluid flows inside the finned tube coils. Axial fans move outdoor air through the V-shaped coil banks. Heat transfers from the fluid to the coil tubes, from the tubes to the fins, and from the fins to the air stream.

V Type Design
Why Choose a V Type Dry Cooler?
V type design is selected when a project needs dry air-cooled heat rejection with higher coil surface area in a compact footprint. It is especially useful for closed-loop cooling systems where water use, plume, spray water treatment or open-loop contamination should be reduced.
Low Water Consumption
Standard dry operation rejects heat without an open evaporative water loop or continuous make-up water.
Closed-Loop Fluid Protection
Water or glycol stays inside the coil circuit and is not exposed to outside air.
Free Cooling Potential
Can support free cooling when ambient air temperature is low enough to reduce or bypass chiller operation.
Suitable for Outdoor Installation
V type dry coolers are designed for rooftop, ground-mounted and industrial outdoor installations.
Custom Fan and Control Options
Fan speed control, EC fans, low-noise design, coil coatings and control panels can be customized.

| Capacity Density | Higher coil surface area within a compact footprint | Usually suitable for lower profile or specific airflow layouts |
| Footprint | Compact for medium to large heat rejection loads | Can require longer layout depending on capacity |
| Airflow Path | Air passes through angled coil banks and fan section | Airflow depends on flat coil and fan arrangement |
| Best For | Higher capacity outdoor dry cooling and free cooling projects | Low-profile installations or projects with specific height limitations |
| Selection Logic | Choose when capacity, compact footprint and coil area are priorities | Choose when profile, airflow direction or site layout requires it |
System Comparison
V Type Dry Cooler vs Cooling Tower vs Adiabatic Cooler
These three heat rejection solutions serve different project priorities. A V type dry cooler minimizes water use, a cooling tower provides evaporative cooling closer to wet bulb temperature, and an adiabatic cooler combines dry cooling with limited water-assisted pre-cooling during hot conditions.

|---|---|---|---|
| Cooling Method | Sensible air cooling through finned coils | Evaporative cooling with water exposed to air | Dry cooling with water-assisted air pre-cooling when needed |
| Water Use | Very low or none in standard dry operation | Continuous make-up water required | Lower than cooling tower, higher than dry-only operation |
| Fluid Protection | Closed-loop fluid inside coils | Open water loop in many systems | Closed-loop fluid inside coils |
| Temperature Limit | Limited by ambient dry bulb temperature | Limited by wet bulb temperature | Can approach lower temperatures than dry-only operation |
| Best For | Low-water closed-loop cooling and free cooling | Lowest practical evaporative water temperature | Projects balancing water saving and hot-weather performance |

FAQ
V Type Dry Cooler FAQ
These FAQs are written for HVAC engineers, industrial buyers, data center teams and contractors who need to understand V type dry cooler selection, operation, controls, maintenance and customization.
What is a V type dry cooler?
A V type dry cooler is an air-cooled heat rejection unit with finned tube coils arranged in a V-shaped configuration. Process fluid, water or glycol flows inside the coil, while ambient air is drawn or pushed across the finned coil surface by axial fans. Heat transfers from the fluid to the coil tubes and fins, then to the outdoor air. Unlike open cooling towers or evaporative condensers, a dry cooler normally rejects heat without direct water evaporation.
How does a V type dry cooler work?
Hot fluid enters the finned tube coil and flows through the closed coil circuit. Axial fans move ambient air across the V-shaped coil banks. Heat transfers from the fluid to the tube wall, from the tube to the fins, and then from the fins to the air stream. The cooled fluid leaves the coil and returns to the chiller, process equipment, heat exchanger, data center loop or industrial cooling system.
Why choose a V type dry cooler?
A V type dry cooler is selected when the project requires closed-loop fluid cooling, low water consumption, outdoor air-cooled heat rejection and a compact high-capacity coil arrangement. The V-shaped coil layout provides more coil surface area within a practical footprint, making it suitable for HVAC, process cooling, free cooling and industrial systems where water use or water treatment should be minimized.
What is the difference between a V type dry cooler and a horizontal dry cooler?
A V type dry cooler uses V-shaped coil banks with fans typically arranged above the coil section, allowing large coil surface area in a compact footprint. A horizontal dry cooler usually uses flat horizontal or vertical coil arrangements depending on design. V type units are often preferred for higher capacity and compact outdoor installation, while horizontal dry coolers can be useful for lower profile installations or specific airflow layouts.
What is the difference between a dry cooler and a cooling tower?
A dry cooler rejects heat through sensible air cooling over finned coils and keeps the process fluid inside a closed coil circuit. A cooling tower rejects heat mainly through evaporative cooling and normally uses water exposed to air. Dry coolers use little or no water during normal operation, while cooling towers can achieve lower fluid temperatures closer to wet bulb temperature but require make-up water and water treatment.
What is the difference between a V type dry cooler and an adiabatic cooler?
A standard V type dry cooler uses ambient air only to cool the fluid. An adiabatic cooler adds a pre-cooling or wetted media system to reduce the air temperature before it reaches the coil during hot conditions. Adiabatic coolers can provide lower fluid temperatures than dry-only operation, but they use some water and require additional water-side maintenance.
What information is needed for model selection?
Important selection data includes heat rejection capacity, fluid type, glycol concentration if applicable, fluid flow rate, inlet fluid temperature, required outlet fluid temperature, design dry bulb temperature, altitude, project location, installation space, noise requirement, power supply and material preference.
Why is dry bulb temperature important for dry cooler selection?
Dry bulb temperature is the main ambient design condition for dry coolers because the unit rejects heat through sensible air cooling. The leaving fluid temperature is limited by the ambient dry bulb temperature and the selected approach. A high design dry bulb temperature requires a larger coil area, more airflow or a higher allowed outlet fluid temperature.
What materials are commonly used?
Common material options include copper tubes, aluminum fins, stainless steel tubes, galvanized steel casing, Aluzinc steel casing, stainless steel casing, epoxy-coated fins and special anti-corrosion coatings. Material selection should consider ambient environment, coastal exposure, industrial pollution, fluid compatibility and required service life.
What should I send to get a quotation?
To receive an accurate quotation, send the heat rejection capacity, fluid type, glycol concentration, flow rate, inlet and outlet fluid temperatures, design dry bulb temperature, project location, altitude, power supply, installation space, noise requirement, material preference and any control or customization requirements.
