Core HEX CORE is a counter flow heat exchanger that ensures maximum heat transfer, low pressure loss, constructed of thermally conductive and durable aluminum. With our recirculation defrost strategy the sensible heat recovery efficiency (SRE) at -25C (defrosting) can be within a few percent of the 0C SRE (no defrost) delivering significant energy savings. Each core is tested to ensure very low leakage.
