AirChiller – Compact Refrigeration Technology with the Safety Refrigerant Water (R718) and Glycol-Free Cooling

LUMI cooler meets eChiller…
a win-win combination for overcoming today’s challenges of refrigeration technology.

The AirChiller is an air-cooled refrigeration system for outdoor installation offering a refrigeration capacity of 70 kW. It combines the benefits of the Michelbach group’s glycol- and chemical-free LUMI cooler with those of Efficient Energy GmbH’s eChiller model series that operate exclusively with the safety refrigerant Water (R718).

The LUMI cooler, which works entirely with fresh water and high-pressure humidification, and is available with or without adiabatic functionality, has a hygiene certification in accordance with VDI 2047, Sheet 2. The eChiller uses water (R718) as refrigerant, and thereby fulfils the F-Gases Regulation and increasing safety requirements for refrigerants. The components’ hydronic and control systems are interconnected. Thanks to its integrated free cooling and energy-optimised control at any stage of operation, the AirChiller fulfils the Ecodesign Directive’s requirements set out in Regulation EN2016/2281. It not only surpasses today’s mandatory minimum standards, but also easily beats the threshold values that will take effect from 2021. EN 378 is of no relevance for the AirChiller.

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 AirChiller is configured for low cooling-water and high outdoor temperatures, and is ideally suited for cooling of data centres, industrial processes and buildings.

The frost-proof version of the integrated unit allows outdoor operation using water as a refrigerant, even during winter. The system is delivered as an integrated module. Only suitable power and water supplies are needed. Whether you’re 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.

AirChiller – a successful partnership between the Michelbach group and Efficient Energy GmbH
The AirChiller is the result of a joint venture between Zirndorf-based Michelbach group and Efficient Energy GmbH of Feldkirchen near Munich. Both companies offer the AirChiller through their respective sales channels.
