Polyurethane System

Refrigeration & Freezing insulation

The rigid polyurethane system widely used as an insulating material for refrigerator compartments, freezing containers, refrigerator displays, and freezers greatly contributes to the eco-industry by reducing the energy needed for maintaining refrigeration and freezing facilities and minimizing carbon dioxide emission.
Polyurethane foam in refrigeration and freezing insulation system provides the best insulation functions to be able to safely preserve food in processing, storage, and distribution to customers.

Woojo Hightech Co., Ltd.’s polyurethane refrigeration and freezing insulation system pursues eco-friendly and high-efficiency cooling system.
