Frozen food refrigeration hydro-chiller

Hydro chillers are a type of refrigeration equipment that uses water as a cooling medium instead of traditional refrigerants. Furthermore, they are commonly used in commercial and industrial settings such as supermarkets, warehouses, and cold storage facilities. 

In fact, installing hydro chillers requires a thorough understanding of the equipment and the building’s refrigeration system. So let’s delve into the hydro-chiller refrigeration installation process and how it can benefit your business.

Site evaluation

Site evaluation is an essential step in the process of installing hydro chiller refrigerators. Because it helps to determine the best location for the equipment and any necessary modifications to the building’s refrigeration system. Therefore the site evaluation process typically includes the following tasks:


  • Assessing the space available for the hydro-chiller: The hydro-chiller equipment is large and requires a significant amount of space. This includes assessing the available space in the building and determining the best location for the equipment.
  • Determining the cooling load of the building: The cooling load of a building is the amount of cooling required to keep the building at a comfortable temperature. An examination needs to occur of the cooling load of the building to determine the appropriate size of the hydro-chiller equipment.
  • Assessing the availability of water and electricity: Hydro chillers use water as the cooling medium and require a constant supply of water and electricity. An evaluation of the building’s plumbing and electrical systems to ensure it is standard for the hydro chillers.
  • Assessing the existing refrigeration system: Hydro chillers are often used to upgrade existing refrigeration systems. This means the existing refrigeration system needs to be assessed to determine if any modifications need to be made to the existing system to accommodate the hydro chiller.

Equipment Preparation

Installation preparation for hydro-chiller refrigerators is a crucial step in the installation process as it ensures that the equipment is correctly set up and ready for operation. Furthermore the equipment preparation process typically includes the following tasks:

  • Piping and ductwork: The piping and ductwork need to be properly installed. Therefore this includes installing any necessary valves, pumps, and filters to ensure that the water flow is sufficient and that the hydro-chiller is properly draining the water.
  • Electrical connections: Hydro chiller refrigerators also require a constant supply of electricity. So this includes connecting the hydro-chiller to the building’s electrical supply and installing any necessary wiring, circuit breakers or fuses to ensure the hydro chiller has a reliable power source.
  • Testing: Lastly once the hydro-chiller is connected to the water supply, drainage, and electrical supply, an examination of the water flow and pressure needs to occur to ensure it’s up to standard. This step is called commissioning.

  • Delivery of Hydro chiller: The hydro-chiller is delivered to the site once the equipment is prepared. 
  • Control systems: Hydro chiller refrigerators have a control system that allows the equipment to be operated and monitored remotely. This includes installing any necessary sensors, thermostats, and other components to ensure the control system can properly work with the hydro-chiller.
  • Commissioning: The hydro-chiller is then commissioned, which includes testing the water flow and pressure and adjusting any necessary settings.


Finally, the building’s staff is trained to properly operate and maintain the hydro-chiller refrigerator. It’s important to note that a trained and certified professional should perform the installation process of hydro-chiller refrigerators to ensure that the installation is done correctly and safely.

Following the proper installation process, businesses can ensure the hydro-chiller refrigerator is installed correctly. This can reduce the costs of modifying the building’s refrigeration system to ensure that the hydro-chiller refrigerator operates effectively and efficiently.
