Engie launch R1234ze Spectrum chiller
Based on the company’s Quantum Water chiller, the Spectrum will be available for order in October in six basic models.
This water-cooled brine cooler features oil-free high-lift turbo compressors, low GWP refrigerant R1234ze and a rated refrigeration capacity of 170 to 1,100kW with chilled medium outlet temperatures reaching -10°C. It will also be available with non-flammable A1 refrigerant R515B.
Accurate control is provided by a Siemens S7 PLC as its central control instrument with an accurate PID controller.
In addition to the oil-free turbo compressors with magnetic bearings, the models feature flooded tube bundle heat exchangers, and an open-flash economiser integrated as standard.
Engie says that users can also operate the Spectrum Water as a brine/water heat pump, for example in combination with ice storage systems, near-surface geothermal energy or air-pressurised hybrid coolers as a heat source. In this case, the machine produces rated thermal outputs of between 170 and 1,060kW at cooling medium temperatures of up to 50°C, making it suitable for all types of low-temperature comfort heating applications.
