Circuladores de refrigeración de frecuencia variable serie LTZ Enfriadores
APLICACIONES
LTZ series low-temperature freezers use frequency conversion technology to achieve high-efficiency energy saving of products, temperature control range: -100℃~30℃, temperature control accuracy: ±0.3℃
The variable frequency compressor unit changes the operating speed of the DC compressor at any time according to the user's cooling and heating load requirements through the built-in frequency conversion device, thereby avoiding the compressor and electric heating full load confrontation, maintaining a stable working state of the unit and achieving energy-saving effects.
