How does the energy regulation system work?
The chillers support stepless or phased energy regulation. Depending on the model, the energy regulation range can be set to 0-33-66-100% or 0-25-50-75-100% to optimize energy consumption and match load requirements.
Can these chillers be integrated into building management systems?
Yes. The units can be connected to building control systems using an optional control module, enabling convenient remote monitoring, control, and automation.
What built-in safety protection features are included?
The chillers feature comprehensive protection systems, including compressor motor overheating protection, unit overload protection, high/low pressure protection, frost protection, power reverse phase/phase protection, exhaust over-temperature protection, and flow switches.
What are the heat exchanger options for the evaporator and condenser?
The standard configuration uses high-performance dry shell and tube heat exchangers. Optional stainless steel plate heat exchangers are also available to suit specific process water requirements.
