Efficient Energy GmbH

The eChiller is the only chiller worldwide that uses only the safety refrigerant water (R718) as its refrigerant, is manufactured in series production, and is based on an innovative technology that allows extremely energy-efficient operation. The eChiller is exempted from the F-Gas Directive and refrigerant-related safety requirements, offers sustainable refrigeration, and releases owners from time-consuming and costly operating obligations.

eChiller operators benefit directly on multiple fronts:

• Chillers that use water as a refrigerant are exempted from all of the F-Gas Directive’s environmental and safety guidelines that apply to fluorinated refrigerants
• The appliance switches to free cooling mode when the cooling water temperature drops marginally beneath the required chilled water temperature; depending on the application  in question, this can cut energy consumption by up to 80% compared to other state-of-the-art technologies
• The eChiller not only fulfils the efficiency requirements of the first stage of the Energy Related Products Directive EN2016/2281 which took effect in January 2018, but also the enhanced requirements of the second stage, which will come into force from 2021
• By using the safety refrigerant water, the extremely quiet and low-vibration eChiller can also be installed outside machine rooms, and it is exempted from operators’ safety-related obligations for chillers under DIN EN 378
• Refrigerant costs are limited to filling the system once with 60 litres of drinking water; if the system is taken out of service, the water can be unconditionally disposed of with regular wastewater
• The initial investment costs can also be reduced thanks to the eChiller’s eligibility for BAFA subsidies

The eChiller is optimally suited to application areas such as server- and switch-room cooling, building cooling – notably building-component activation and chilled ceilings – and industrial-process cooling, such as moulding production and extrusion.

The eChiller is available in two designs depending on the operating environment:

The eChiller is designed for cooling processes with high chilled water inlet temperatures. It optimal cooling capacity lies in a range from 16°C to 22°C, but inlet temperatures of between 10°C to 28°C are also possible – a spectrum that traditional chillers are only partially capable of covering.

The eChiller is available in two designs, with a nominal cooling capacity range of 20 to 45 kW, depending on the configuration of the chilled water outlet temperature and compressor. Total capacity can be scaled to over 300 kW by combining several systems.

Full-Service-Package:

Efficient Energy GmbH of Feldkirchen near Munich is the developer, manufacturer and system supplier of the eChiller. Besides the chiller, we also offer modules comprising all the hydraulic component needed for a turnkey installation. We’ll assist you in all eChiller-related matters and, if needed, help your planner integrate the eChiller into your application.

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.

Energy-efficient cooling technology with the safety refrigerant Water (R718) – that is what’s on offer with the eChiller product range of the Efficient Energy GmbH – the world’s only mass-produced cooling systems to date that are exempted from the F-Gas Regulation and coolant-related safety requirements.

The eChiller product range is optimally suited to cool server rooms, industrial processes and buildings. The eChiller is available with cooling capacities ranging from 20 kW to 45 kW and can be scaled modularly up to more than 300 kW.

Today’s answer to overcoming -increasing regulatory challenges

By using the natural safety refrigerant Water (R718), the eChiller already fulfils the new F-Gas Regulation and increasing refrigerant-related safety requirements. As such, it exempts operators permanently from the costly and time-consuming maintenance duties associated with other refrigeration machines.

When the cooling water temperature drops marginally below the required chilled water temperature, the system’s fully adjustable, integrated control switches to free cooling mode. Depending on the application at hand, this can cut the annual energy consumption by up to 80% compared to other state-of-the-art technologies. The eChiller not only fulfils the efficiency requirements of the Energy Related Products Directive EN2016/2281, but also the enhanced requirements that will first take effect in 2021.
