Frigofresh

The thermal insulating Frigofresh panels of Kamaridis GlobalWire Group are complex, self-supporting structural elements, especially designed for the construction of cooling chambers and rooms with high thermal insulation and water tightness requirements and controlled special ambient temperature and humidity. They are formed in 80mm to 140mm thick sheets and its main use is for conservation chambers in contrast to Frigocool polyurethane panels which are for deep freezers produced in 160mm to 200mm thick sheets.

Characteristics

After extensive research in both domestic and foreign markets and the gathering of technical details and opinions from specialist in the field of cooling chambers. Kamaridis GlobalWire Group pioneers a new trapezoidal junction, a method that eliminates thermal bridge to the steel sheet and also excludes other hardcore pu polyurethane infusions to the larger gauzes.

This new Trapezoidal junction of panels 80-140mm that are intended for maintenance chambers (+5 to -18°C) and panels 160-200mm that are intended for deep freezing chambers (blast freezer to -50°C), pilots the way because the elusive air is linear and ends when it becomes trapezoidal, thus eliminating thermal loss.

By virtue of a truly proper fitting, Frigocool thermal insulating polyurethane panels absolutely abide by their specifications satisfying all customer requirements.

They consist of two metal sheets and coating of self-extinguishing tough polyurethane resin. The standardized plate sheets of the panels are formed from pre-painted steel and can be flat or of smooth modulation such as WPU.

The special forming of the male-female panel ends, in order to interlock during fixing, provides the panels with full tightness and increased thermal insulation, without the need to protect the joint with additional sealing materials.

Natural characteristics

Frigofresh cross section

Frigofresh joint

The foam is odorless, prevents the formation of mold and fungus, remains chemically neutral and the humidity does not change its mechanical capacities. Sensitive to the texture of the excessive sunlight and in contact with water only at the exposed surface as well.

Foam expansion

Pentane is used in foam expansion which is friendly to the atmosphere and to the environment in general as it is chlorofluorocarbons free (CFC & HCFC Free.)

Specifications of PVC coating

In most storage and food processing facilities, the use of PVC covering panels is required. PVC is available in two colors (RAL9002 & RAL9010) and in 120mic thickness. Both colors are certified and suitable for use in food storage and processing applications according to all European standards and regulations (78/142 / CEE, 80/766 / CEE, 82/711 / CEE, 85/572 / CEE, 90 / 128 / CEE, 92/39 / CEE).

Seals - Support Materials - Special Items

For proper installation of the FRIGOFRESH panels required a series of binders available from our company (self-screws, washers, gaskets).

The use of 2.5 screws per m2 is recommended.

For screws with greater captive capacity please contact us.

After the installation of panels, it is necessary a number of special items for both sealing and for aesthetic completion of construction.

Each building has its own specific needs.

Please contact our technical department in order to adapt the necessary special items on your own construction.

Environment

The FRIGOFRESH coating system of our company is produced from materials friendly to the environment, (CFC free), characterized as ecological and not considered to be harmful.
