ProfHolod delivers PUR Classic and PIR Premier insulated panels, hinged and sliding refrigeration doors for construction of cold storage warehouses, cold chambers and distribution centers.
Refrigerated warehouses are used to store your fruits, vegetables or other products at controlled temperatures to prolong their life.
Insulated cold storages are used in many industries:
Storage of fruits and vegetables
Speciality applications like data centers, preserving artwork, etc
Cold storage temperatures
ProfHolod manufactures PUR and PIR insulated panels and insulated refrigeration doors for a wide variety of cold storages, including
Medium temperature refrigeration, above 0°С
Low temperature refrigeration, below 0°С
Building of refrigerating warehouses and chambers
The service package related to the building of refrigerating chambers and warehouses includes:
Design and construction or the refrigerating chamber
Supply of wall and roofing sandwich panels with the polyurethane foam PUR or fire-proof polyisocyanurate PIR filler
Supply of shaped profiles, flashings
Supply of refrigeration doors, PVC strip curtains
Selection and supply of refrigerating equipment
Availability of the own manufacturing facilities and of highly competent experts makes it possible to fulfill the project documentation development and the construction of the refrigerating warehouses in the shortest possible time.
Refrigerating warehouses construction aspects
The refrigerating warehouse is built according to the skeleton technology. The skeleton is made of metalwork and can be covered with polyurethane foam panels (PUR, PIR) either inside or outside. Either vertical or horizontal panel placement are allowed. At the same time, even after the erection of the warehouse, it is possible to make an on-the-fly layout change, or to create refrigerating chambers with different temperature conditions.
Thanks to the particular design of the sandwich panel junction locking profile, the “cold bridges” are completely eliminated and the maximum thermal and hydro insulation of the refrigerating warehouse is provided.
The low weight of the panels allows to avoid the use of huge building machinery, to reduce the stuff involved in the mounting works and to use lighter and cheaper foundations (which allows significant savings).
The simplicity in cutting the panels and the cancellated structure of the skeleton allow to create quickly additional windows and doors.
The solid, low weight metalwork skeleton can carry heavy suspended equipment.
The unique energy saving properties of ProfHolod’s sandwich panels with the polyurethane foam (PUR, PIR) filler considerably reduce the technical requirements for the refrigeration equipment power (it is possible to use less powerful therefore, lower energy consuming refrigeration equipment).
The special ProfHolod’s refrigeration doors are accurately selected according to the temperature conditions of the warehouse and allow to reduce significantly the thermal loss during the operation of the structure.
If necessary, the refrigerating warehouse can be disassembled and transported to a new location.
ProfHolod’s sandwich panels are certified and have passed sanitary-epidemiological expertise. They are approved for the use in the erection of the food industry buildings.
Comprehensive approach, high quality of construction materials and competence of the company experts guarantee long service life of the warehouses built with ProfHolod’s polyurethane foam sandwich panels.
Polyurethane foam sandwich panels (PUR, PIR)
Building the refrigerating warehouses and chambers, we use ProfHolod’s sandwich panels having the thickness from 40 mm to 200 mm, with the solid polyurethane foam PUR or fire-proof polyisocyanurate PIR filler (components Dow Chemical, foam density 42-45 kg/m3).

GOST Р 51032-97
Sandwich panel surface – the metal supplied by the leading Russian manufacturers (Novolipetsk Metallurgical Combinate (NLMK), Severstal, INSAYUR Group). The thickness of metal is 0,5 – 0,7 mm.
Variants of surface (depending on the functional purpose of the chamber or warehouse):
Galvanized steel coated with polyester paint (according to the RAL catalogue)
Depending on the warehouse’s functional purpose, different types of refrigeration doors are used: hinged (lay on or hidden, single or double) or sliding.
The doors can be either medium temperature or low temperature. They are made in different colors (according to the RAL catalogue) and have various surface materials. They are equipped with high-quality European hardware.
In order to realize joints and connections while building the refrigerating warehouses, metal shaped profiles (flashings) are used: channels, internal and external angles, flashings. They are made in various colors (according to the RAL catalogue).
