Type of Dry Fluid Cooler

Here are the primary types of Dry Fluid Coolers:

This is the most common way to categorize dry coolers.

Design: The fans are mounted on top of the unit, pulling air vertically upward through the heat exchanger coils and then discharging it.
Pros:

Space-Efficient Footprint: Ideal for installations where floor space is limited but height is

not a constraint.
- Good Air Discharge: Warm exhaust air is ejected high, reducing the chance of recirculation.
Cons:
- Generally taller and may require more headroom.
- Can be more challenging to service fans and motors.
Best For: Rooftop installations, parking garages, and areas with limited ground space.

Design: Fans are mounted on the side(s) of the unit, pulling air horizontally through the coils and discharging it out the opposite side.
Pros:
- Low Profile: Easier to fit under low ceilings or in mechanical rooms.
- Easier Maintenance: Fans and motors are typically more accessible at ground level.
Cons:
- Larger Footprint: Requires more floor space.
- Risk of Recirculation: If not spaced properly, warm discharge air can be sucked back into the intakes, reducing efficiency.
Best For: Ground-level pads, mechanical rooms, and installations where height is restricted.

This describes how the fan interacts with the coil.

Design: The fan is located on the air inlet side, pushing ambient air through the heat exchanger coils.

Pros:
- Easier to access fan blades and motors for maintenance since they are on the cooler ambient air side.
- Generally quieter operation because the fan is handling cooler, denser air.
Cons:
- Airflow across the coil can be less uniform.
- The fan motor is exposed to the weather.

Design: The fan is located on the air discharge (outlet) side, pulling air through the heat exchanger coils.
Pros:
- More uniform air distribution across the entire coil surface.
- The fan pulls the warm air, which can be beneficial for preventing frost in freezing conditions.
- Fan motor is housed within the unit, offering some weather protection.
Cons:
- Fan and motor are subjected to hotter, potentially corrosive exhaust air, which can reduce their lifespan.
- Can be slightly noisier as the fan is handling faster-moving, warmer air.

Design: The unit cools one single, independent fluid stream.
Use Case: Standard applications where only one process or one temperature needs to be controlled.

Design: A single dry cooler frame houses two or completely separate heat exchanger circuits. This allows it to cool two different fluids (e.g., process water and hydraulic oil) or two separate loops from the same system.
Use Case: Complex facilities where space is limited, and multiple systems need cooling.

Uses a water-glycol mixture (e.g., 40% glycol, 60% water) as the process fluid to prevent freezing in cold climates.

Design: This is a special type that combines the dry operation with a minimal evaporative function. A pump and misting system spray a fine mist of water onto the air intake side of the coil only when ambient temperatures are high.
How it works: The evaporation of this water spray cools the incoming air before it passes over the coil. This allows the unit to reject heat much more efficiently on hot days, approaching the performance of a cooling tower.
Advantage: Offers the water-saving benefits of a dry cooler 95% of the time, with the high-temperature performance of a wet cooler when it’s needed most. It uses a fraction of the water a full cooling tower would use.

Design: Features adjustable louvers (dampers) that can control the amount of air flowing through the coil.

Purpose: In cold weather, the dampers can close off airflow to the coil to prevent the fluid

from freezing or getting too cold, which could damage the process. This allows for precise temperature control year-round.
