Polyurethane foams - Import export

SDP series doors are designed for positive temperature cold rooms, that maintain a temperature of 0°C or higher. Injected with 68 mm thickness polyurethane foam these doors can guarantee maximum thermal insulation and protection of premises. A special sliding mechanism, made of high-quality aluminum profiles, ensures smooth door movement and convenient access to the premises. Standard door surface is made from a painted metal sheet and covered with polyester, but there are possibilities to use stainless steel or fiber glass for better durability. Special plastic profile frames help prevent cold leakage and ensure constant cold temperature preservation in the room. Doors are also equipped with a special micro-lift technology and an inside emergency lock.

DPO series doors are designed for positive temperature cold rooms that maintain a temperature of 0°C or higher.

Refra manufactures pumps stations for water treatment systems of various sizes. These systems are designed for particularly sensitive equipment cooling with water and becoming increasingly popular in robotic factories. Combining the pump station with all kinds of water cleansing filters results in a natural cooling solution with extremely pure water. Assembled in a special walk-in container, this unit be placed outdoors – right next to the building, resulting in reduced installation costs and easy unit maintenance. Additional options, such as illumination, ventilation and heating can be integrated inside the container to make the service of the unit even more convenient. Container size ranges from 2,4 meters to 13 meters in length and can be insulated with polyurethane foam or 50 mm rock wool material for a super silent unit operation.

High capacity condenserless chillers with the cooling power up to 2 MW are designed for immense industrial and commercial buildings with high-power demand. Refra offers condenserless chillers that can be connected to an existing condenser or a complete system with Refra condensers. Assembled in a special walk-in container this unit is ideal for buildings where indoor installation is not possible. It can be placed outdoors – right next to the building, resulting in reduced installation costs and easy unit maintenance. The condenser can be installed either on top of the container or somewhere else. Additional options, such as illumination, ventilation and heating can be integrated inside the container to make the service of the unit even more convenient. Container size ranges from 2,4 meters to 13 meters in length and can be insulated with polyurethane foam or 50 mm rock wool material for a super silent unit operation.

High capacity liquid-cooled chillers with the cooling power up to 2 MW are designed for immense industrial and commercial buildings with high-power demand. The special design of the walk-in container is ideal for buildings where indoor installation is not possible. These chillers can be placed right next to the building or on the roof, which will not only reduce installation costs, but will also allow easy unit maintenance. Additional options, such as illumination, ventilation and heating can be installed inside the container to make the service of the unit even more convenient. Modular assembled container size ranges from 2,4 meters to 13 meters in length and can be insulated with polyurethane foam or 50 mm rock wool material for a super silent unit operation. On request, these units can be equipped with supplementary hydraulic module inside the container and a dry-cooler on top of it.
