The AirChiller is an air-cooled refrigeration system for outdoor installation offering a refrigeration capacity of 70 kW. The AirChiller combines the glycol- and chemical-free LUMI cooler with the eChiller, a refrigeration system that operates exclusively with the safety refrigerant water (R718).
The LUMI cooler works entirely with fresh water and high-pressure humidification and is available with or without adiabatic functionality. The system has a hygiene certification in accordance with VDI 2047, Sheet 2. The eChiller uses water (R718) as refrigerant, and thereby fulfils the F-Gas Regulation and increasing safety requirements for refrigerants. The components’ hydronic and control systems are interconnected and work highly energy-efficient at any stage of operation thanks to its integrated free cooling and energy-optimised control.
The complete integration of the eChiller and the LUMI recooler into a compact refrigeration system ensures energy-optimised control at all operating points. The system is delivered as an integrated module. Only suitable power and water supplies are needed. The AirChiller offers a high level of operating safety combined with maximum savings in operating costs. Time and cost-intensive operating duties can be avoided as the system operates without chemicals, but purely with water.
The frost-proof version of the integrated unit allows outdoor operation using water as a refrigerant, even during winter. Whether you are upgrading a legacy system or installing a new one, the AirChiller is a sustainable and cost-efficient solution for chiller operators, and one that is also eligible for BAFA funding.
