LNEYA è specializzata nella produzione di refrigeratori criogenici monofluido. La temperatura di refrigerazione varia da -150°C a -5°C, in grado di soddisfare le esigenze di diverse temperature di refrigerazione. L'azienda ha sviluppato un refrigeratore a bassissima temperatura a raffreddamento diretto, utilizzando compressori di marca internazionale Carrier, con modalità di refrigerazione automatica a cascata e refrigeranti miscelati, che in 3 minuti può essere refrigerato fino a meno 120°C.

6. Offrendo l'installazione della macchina e il test del sistema, gli utenti devono solo completare l'installazione del refrigerante e dell'acqua di raffreddamento.

Ampiamente utilizzato nell'industria chimica, farmaceutica, biochimica e in altre industrie nel campo delle reazioni a bassa temperatura, della velocità di refrigerazione, della sicurezza e dell'affidabilità.
