Many of these industrial air processes require the air handling units to withstand corrosive, moist and dusty air and gas flows. This rules our conventional aluminium heat exchangers since they would not last very long in such environments.
The GUPEX® air to air (gas to gas) plastic plate heat exchangers operate in dusty environments without the need for air filters to protect it from clogging up the plates. The construction is made of plastic composites (polyester, GPR), resistant to most acids and chemicals. These plate heat exchangers are also designed to operate successfully in extremely dusty environments.
