In January 2010, in Domodedovsky district of Moscow region, «Lesstor» Ltd., warehouse complex for ice storage and frozen storage within the composition of «PRODCONTRACT» GC, was brought into operation. «STEP» group of companies has developed a project and performed works on reconstruction of the existing dry storage complex. Taking into account the high requirements to energy consumption, restrictions stipulated by the building’s construction and logistics design, the specialists with the engineering department made the optimal design choice to modernise the warehouse complex and equip it with cooled products chamber with controllable temperature regimes.

Within the volume of project design and mounting works, the following types of work were performed:
— refined were various architectural and concept designs solutions;
— the building metal constructions were elaborated;
— mounting of heat insulating walling constructions;
— assembly of fast vertical-lift and retractable gates and dock equipment;
— assemblage of refrigeration supply, heating, ventilation and conditioning systems;
— assemblage of a soil heating system in the freezer;
— assemblage of the system of mobile, gravitation and stationary racking constructions;
— a complex of solid-state lighting of the refrigerating chambers.

Refrigerating terminal has a low-temperature and medium temperature storage zones:
— a low-temperature compartment with the volume of 35 000 m3, 5400 pallets, and temperature regime of 25 °С.
— medium temperature compartments with the total volume of 7 000 m3, and temperature regime of 0° ... +5 °С.

The total refrigerating capacity of the refrigeration supply exceeded 1 mW. The equipment reservation principle allows for a temperature regime in the compartments during conduction of routine maintenance and contingencies.

The property of the refrigerating equipment is the aggregate part placed in the module compressor compartment installed outside, which allowed for allocation of extra space for the warehouse complex, and eliminate noise of the operating equipment. Automated monitor system of «ARTIKA» refrigerating equipment allows for flexibility of the remote control over the refrigerating sets, and does not require permanent presence of a service engineer.

One of the principle achievements of «STEP» GC is an innovative control system for dynamic racking and solid-state lighting, considerably decreasing the energy consumption at the complex.

The lighting system performed on the basis of light emitting diode lamps provides for the maximum possible comfortable lighting of work places of the personnel and areas of operation of hoisting and transport facilities at the minimal lighting of inactive areas of the chamber.

The capacity of the freezing warehouse was duplicated due to availability of dynamic racking constructions.

Absence of mobile racking constructions would have required an increased of the warehouse floor space which would have led to a growth in capital costs for construction, and considerably increased exploitation expenditures on cooling and lighting of the complex.

Management of logistical operation at the warehouse is performed with the help of the up- to-date «Pick-by-Voice» voice technology which enables the warehouse workers to maintain the direct voice-to-voice communication with the control systems of the warehouse, relay information without executing it in an electronic or physical form, and correspondingly perform a number of essential warehouse activities. Thanks to «Pick-by-Voice» technology, the warehouse activities require minimum quantity of a supporting staff, while the time for logistics operations has been significantly reduced.
«LESSTOR» Ltd. warehouse complex is the paramount of a complex organisation of building of modern refrigerating terminals meeting all the requirements to energy saving, occupational safety and environmental protection, reliability of the temperature controls, and efficient performance of warehouse activities.
