Based on the plate and nozzle orientation, each fluid passes through alternative channels within the exchanger. An extremely high heat transfer coefficient is attained due to the flow in each channel. The specially designed and tested pattern causes a turbulent flow of the fluid resulting in higher heat transfer and reduction of the amount of deposits inside the unit. The fluids can be plumbed in counter or co-current way.We provide a limited lifetime warranty against manufacturer's defects. ***We will ship to Alaska/e call for shipping quote***
