The TPL series is a special development for the demands in mechanical engineering and plant engineering (e.g. for cooling of hydraulic oil and motor oil). The TPL volume of flow gap is up to 80% larger compared to units with conventional heat exchanger plates. The combination of special turbulence sheets inserted in the flow gaps, thermodynamically efficient diagonal media flow, and maximal diameter connections, allows for very high heat transfer rates to be obtained. Variable designs of these elements allow for optimal adaption to different applications. Due to the efficient performance of the FUNKE TPL for media with higher viscosities, the unit can be of a much smaller size compared to conventional plate heat exchangers.
