HWAR-LH Series - Hot Water Driven Cooling

HWAR-LH series single and double effect chillers convert the heat from hot and superheated water into cooling. Hot water is found in many industries as heat recovery transfer medium such as cogeneration modules, industrial heat recovery, solar heating, district heating, biomass combustion, incineration plants. All units are supplied with 3-port or 2-port hot water control valve to reduce the heat ingress in the chiller at part cooling loads. The control is based on a PID logic to maximize the Coefficient of Performance (COP) at full and part cooling loads. The user can easily operate the chiller through a built-in coloured touch-screen and monitor it through communication protocol options: ModBus RTU, Profibus or TCP/IP.

Our services include the development and manufacturing of customized units for non-conventional applications such as ATEX for installation in areas with explosion risk, special materials for hazardous/corrosive circulating fluids. Years of product R&D, high efficiency solution pre-heating heat exchangers guarantee very high COP up to 0.83 with smaller footprint.
