How a new refrigerated warehouse in St. Petersburg will change the cold storage market

The working meeting in Smolny on October 28, at which Governor Alexander Beglov approved the agreement on the construction of a modern refrigerated warehouse on Salova Street, was a significant event not only for the Frunzensky District, but also for the entire logistics and food infrastructure of the Northern Capital. The implementation of this project by 2028 promises to create a high-tech facility with an area of 1,500 square meters, designed for responsible storage of products at low temperatures. This step is a logical response to the growing demand for high-quality storage facilities in the metropolis and will have a significant impact on related markets, particularly the industrial refrigeration equipment sector.

Growth Stimulus: Implications for the Refrigeration Industry

The construction of such an object will become a powerful catalyst for companies specializing in industrial refrigeration. Firstly, it is a direct order for the supply, installation, and launch of complex turnkey engineering systems. Major Russian and international players will have the opportunity to demonstrate their advanced technologies in a large-scale project. Secondly, the facility will serve as a reference point and demonstration platform for potential customers from the retail chain, logistics operators, and agricultural holdings. The successful operation of the warehouse will be a clear advertisement of the effectiveness of the technologies used.

Thirdly, there will be a steady demand for related services, such as service maintenance, monitoring, and equipment upgrades. This will create new job opportunities for engineers and technicians. Finally, the project will set a new standard for the region, raising the bar for energy efficiency, automation, and environmental sustainability. Manufacturers and integrators will need to meet these increasing expectations, driving innovation and investment in R&D.

The technological heart of a warehouse: key equipment and its functions

The heart of any modern refrigerated warehouse is a complex of interconnected systems. The following types of industrial refrigeration equipment are likely to be used in the project on Salova Street:

1. Refrigeration machines (chillers) and compressor-condenser units (CCU).

   • Function: This is the basis of the system that provides cold generation. The units remove heat from the cooled rooms and dissipate it into the external environment.
   • Characteristics and application: For a large warehouse, powerful semi-hermetic or screw compressor stations (from 100 kW and above) will be used, often in cascade configuration for load regulation flexibility. Natural refrigerant systems (e.g., CO₂) are becoming increasingly popular due to their low environmental impact and high efficiency at low temperatures (down to -25°C and below). These systems are likely to be a priority for facilities built after 2025.

2. Air distribution systems: evaporators and air coolers.

   • Function: Direct cooling of the air inside the storage chambers. They ensure uniform temperature distribution without creating "warm zones".
   • Specifications and application: Different models are selected for different temperature zones (deep freezing, refrigerated products). Key parameters are cooling capacity, air flow rate, and type of defrosting (electric, hot gas). Modern trends include the use of EC-motors in fans, which significantly reduce energy consumption.

3. Refrigeration chambers (sandwich panels) and docking devices.

   • Function: Creation of sealed, thermally insulated rooms. Dock devices (thermal curtains, dock shelters) minimize cold loss during loading and unloading operations.
   • Specifications: Panels made of polyisocyanurate (PIR) or polyurethane (PUR) foam with a thermal conductivity coefficient of 0.022-0.024 W/m·K and a fire safety class of KM0. The insulation thickness for low-temperature chambers can reach up to 200 mm.

4. Automated Control System (ACS).

   • Function: The "brain" of the warehouse. It provides 24/7 monitoring of temperature, humidity, and equipment operation, manages energy-saving modes, generates reports, and alerts about abnormal situations.
   • Features and Applications: Allows you to remotely monitor all parameters, predict load, and prevent downtime. Integration with WMS warehouse management systems is a standard for modern facilities.

5. Backup power supply systems.

   • Function: Guaranteed temperature control during power outages.
   • Application: Diesel generator sets with the required power to support critical loads, as well as uninterruptible power supply systems for controllers.

Thus, the construction of a refrigerated warehouse on Salova Street is not just about building another logistics facility. It is about introducing a high-tech complex into the city's infrastructure, which will serve as a driver for the development of an entire industry. This project will raise the standard of quality for the storage of perishable goods in the region, establish new technological standards, and strengthen St. Petersburg's position as a key logistics hub in the country. It will provide an opportunity for companies operating in the industrial refrigeration sector to demonstrate their expertise and lay the foundation for future, even more ambitious projects.
