Dana water chillers

Types of Dana water chillers

A Dana water cooler has different types that are mainly based on how the water is cooled. These different types of chillers are usually combined into a single unit for convenience and portability.

• Air-cooled chillers

  An air-cooled dana water chiller uses ambient air to cool down the water. It works by circulating air over the condenser coils. The condenser coils are internal components that are kept cool by the flow of refrigerant within them. The coils then release the heat generated from the refrigerant into the environment. This process cools down the water and ice in the compressor using ambient air. Air-cooled chillers are popular because they require little maintenance and are extremely easy to install.

• Water-cooled chillers

  As implied by the name, water-cooled chillers use water to cool down the refrigerant in the system. The water can come from a cooling tower, evaporator condensers, or city water. The water then absorbs the heat generated from the refrigerant and releases it into the environment. Water-cooled chillers have high cooling capacities. In addition to taking up less space compared to air-cooled chillers, they also perform more efficiently, especially in large-scale operations. However, water-cooled chillers require more maintenance and complex installation procedures.

• Wracker chillers

  Wracker chillers are also referred to as screw chillers. They have a unique design that includes a screw compressor. Due to its increased size and capacity, the screw compressor brings a lot of power. Larger buildings and industrial spaces mostly use wracker chillers because they can handle high loads effortlessly. Another benefit that the cooling system offers is that it works quietly compared to other chillers. It is ideal for spaces that need to be silent.

• Portable chillers

  Portable water chillers are relocation-friendly cooling systems that can be moved from one point to another. They do this conveniently by casting wheels on the base so users can push or drag them comfortably. Most of them are air-cooled, but some variants might be water-cooled. The chillers are ideal for temporary setups and manufacturing processes that require cooling from anywhere.
