HRZ

The HRZ plate heat recovery units are designed to recover heat energy from exhaust air in HVAC systems. The HRZ plate heat recovery units have higher efficiency, lower pressure drop and more additional features than the HRV heat recovery units. Air filters should always be installed before the heat recovery units to prevent clogging and thus reducing their efficiency.

The HRZ heat recovery units can be supplied in several different variants according to your requirements: 

The HRZ plate heat recovery units are divided into two basic groups:
HRZF - "flat" respects the installation dimensions of the given series 
HRZT - "thick" minimizes the installation surface and is higher than the dimensions of the given series

They are further divided by design into left BL and right BR and by efficiency classes - class E2016 and E2018.

The HRZ heat recovery units can be ordered in the following versions:
