Lighstream Scroll chillers feature either brazed plate or shell-and-tube heat exchangers, depending on unit capacity and end-customer preference.
BRAZED PLATE HEAT EXCHANGERS
Brazed plate heat exchangers provide optimal heat transfer efficiency, pressure resistance and longest possible service lifetime, guaranteed by their advanced design. Low internal volume – compared to other types of heat exchangers – permits refrigerant charge reduction to a minimum.
SHELL-AND-TUBE HEAT EXCHANGERS
Shell-and-tube heat exchangers with an innovative refrigerant distributor and optimized plastic baffles are designed to improve the waterside heat transfer performance. The tubes have a specific inner-grooved pattern to maximize the heat transfer coefficient and to limit the pressure drop negative effects. This type of evaporators is recommended for optimum efficiency.
