Oil-free turbo compressors with magnetic bearings, flooded tube bundle heat exchangers with the latest inner piping technology optimised for glycol applications, and the open-flash economizer integrated as standard guarantee optimal efficiency values in cooling mode (EER)

In process cooling applications, the chiller excels with SEPR-MT values of up to 4.96, and thereby provides maximum energy efficiency – not just under full load, but at all partial load points, thanks to continuous inverter control. As a result, the machine easily surpasses the strict TIER 2 minimum efficiency performance standards (MEPS) set down in the VO EU 2015/1095 Ecodesign Directive.

Oil deposits in the heat exchangers and the resulting performance and efficiency losses are not a problem. This is because the SPECTRUM Water chiller is based on an oil-free chiller design. The magnetic bearings of the compressor shaft allow the machine to be operated without lubricants hazardous to groundwater. As a result, oil changes as well as laborious and expensive service work on the components for oil return are a thing of the past. Your advantage: lower maintenance costs and fewer service-related downtimes of the system.

The compact dimensions of the system result in unbeatably high power density levels and a specific efficient use of space. As a result, the SPECTRUM Water is suitable for more than just retrofitting in existing technology rooms; it can also be used in container applications where little space is available.

The SPECTRUM Water chiller provides ultimate reliability in operation. Up to six redundantly connected oil-free turbo compressors, high-quality technological components and an optional redundant feed enable the chiller to operate reliably – at all times! Because we know: stable operation is the most important aspect of process cooling.

The concept of the SPECTRUM Water is based on the tried-and-tested QUANTUM Water technology. This technology has been setting new standards on the international cooling market since July 2021 – so you can rely on a proven and mature innovation.

When conversation turns to future-proof chillers, the refrigerant should not be neglected. That is why we deliver our SPECTRUM Water with minimal filling capacities of the low-GWP refrigerant R-1234ze. With a GWP value of lower than one, it convinces with its very low direct greenhouse potential and is thus completely future-proof in terms of the F-gas Regulation. As an A2L refrigerant, R-1234ze is also not readily flammable and non-toxic. This means that operating companies do not require complex safety instruction.

Alternatively, the SPECTRUM Water chiller is available with the highly efficient and non-flammable A1 safety refrigerant R-515B.

When it comes to optimal solutions for maximum energy efficiency, ENGIE Refrigeration is the obvious choice. The SPECTRUM Water chiller is the only standardised modular solution – made in Germany – with an oil-free machine design on the market in its performance and temperature range. For you, this means a fast, simple planning process and an optimal quality-cost ratio.

The SPECTRUM Water relies on a Siemens S7 PLC as the central control instrument of the chiller. In addition, the chiller has an accurate PID controller for top control quality and a stable chilled medium outlet temperature with minimal control deviations from the required setpoint. This makes the machine suitable for any situation where a stable temperature level is required for maintaining processes and ensuring high quality standards.

The machine can be operated with a 10-inch touch panel or via smart control using a mobile end device. This means you can always keep an eye on all the important operating states as well as safety and error messages without having to be by the machine on site. Compatibility with standard BCS protocols also allows the SPECTRUM Water to be easily integrated into a higher-level building control system.

Another highlight is the chiller’s interface with our CoolCare remote maintenance software, which enables continuous improvement and troubleshooting from a different location.

In addition to the standard operation of the SPECTRUM Water as a water-cooled chiller, as a brine/water heat pump it can also be operated in combination with ice storage systems, near-surface geothermal energy or air-pressurised hybrid coolers as the heat source. In this case, the model produces rated thermal outputs of between 170 and 1,060 kilowatts at cooling medium temperatures of up to 50 degrees Celsius. This makes the model perfect for all kinds of low-temperature comfort heating applications.

The outstanding concept of the SPECTRUM Water is suitable for many different industries. The machine displays its full strength wherever low chilled medium outlet temperatures, a large capacity range, maximum operational reliability and top energy efficiency are required.
