PUR foam is used for insulation of almost all cooling pipes and cooling installations due to its impermeability. It is therefore used extensively in the production of insulation jackets for pipes, fittings, etc.
A radial fan is a device that consists of an impeller driven by an electrical motor. The rotation of the impeller sets the air in motion and air is sucked in from the inlet on the side of the fan and blown out of the outlet of the fan.
Radiant heat is thermal radiation between two surfaces. Thermal radiation occurs when a material transmits infrared radiation, thereby warming a second material, without causing the air around the materials to be heated.
