Gas-Tight and CA Warehouses

Склады РГС

The primary concern when making gas-tight and controlled gas environment warehouses for fruit and vegetable storage is their sealing.

Global food losses have been documented at around 25% to 50% of production due to lack of cold chain infrastructure. In Russia this figure amounts to 30-40%, in India – up to 16%. Each year food loss and waste cost roughly $1 trillion in losses around the world. Most of the losses in the cold chain of fruit and vegetable supply occur during the period of product storage.

PH Insulation offers modern sandwich panels made with fire-resistant PIR polyisocyanurate or PUR polyurethane foam core and gas-tight sliding doors for the construction of sealed warehouses and cold storage rooms with CA to preserve and ripen fruits, vegetables and berries.

Unique Docking "Spike-Groove" Lock: a Guarantee of Integrity

The primary tightness of warehouses with CA made of PH Insulation sandwich panels is provided with the unique configuration of a “spike-groove” lock which is 20 mm deep securing minimal cold or heat loss at the joint.

PH Insulation locks provide:

  • maximum thermal insulation and waterproofing of joints of sandwich panels which is approved by air and steam protection certificate

  • rigid connection of the panels by the foam due to the conical chambers

  • the minimum flow rate of foam during panels docking

Depending on the thickness of the wall panels, the "spike-groove" lock can be single, double or triple.
