The PAN-DX series of shell and tube evaporators represents an advanced technological evolution in heat exchangers for air conditioning and refrigeration applications. With cooling capacities of up to 900 kW under nominal conditions, these models offer 1 to 4 independent cooling circuits and 2 baffle distances for varying water flows. Specifically optimized for R407C refrigerant, these evaporators utilize a dedicated high-efficiency exchange tube to significantly enhance performance, resulting in nearly 10% higher cooling capacities. This improvement allows for better COP optimization and higher evaporation temperature, benefiting various refrigerants. Special attention has been given to ensure smooth lubricant oil flow.
