Frequently asked questions

About the Maglev Chiller.

What cooling capacity does the NTC chiller cover?

The NTC series covers 360 – 7 035 kW cooling capacity, equivalent to 100 – 2 000 RT (refrigeration tons). For installations above 200 RT, dual-head configurations are available.

How does the NTC compare to a screw chiller?

COP up to 7.38 versus 4.5 – 5.5 typical for screw chillers, ≤ 80 dB noise versus 80 – 85 dB, 100 % oil-free operation versus oil-lubricated, and maintenance intervals 15 000+ hours versus 8 000 hours.

What is the typical part-load efficiency?

Variable-frequency control and intelligent diffuser logic keep the NTC at very high efficiency across part load — a major advantage over conventional centrifugal chillers, which drop sharply below 70 % load.

Which applications are most common for the NTC chiller?

Commercial buildings, hospitals, schools, data centres, factory workshops, and process refrigeration in chemical, pharmaceutical and food industries.

Is the NTC chiller maintenance-intensive?

No. With no friction and no lubricating oil, the NTC has minimal mechanical maintenance — typically just heat-exchanger cleaning and filter checks. Bearing life exceeds 20 years.
