ACRYLIC ACID FOR SYNTHESIS 
PROPIONIC ANHYDRIDE FOR SYNTHESIS 
Product Features
Environmental protection
• Uses R404a environmentally friendly refrigerant;
• Uses durable, environmentally-friendly polyethurane foam insulated walls to provide excellent insulation with a low ozone destruction coefficient.
Safety
With equipment fault self-diagnosis function. With a variety of active protection and passive early warning functions, the operating status is monitored to ensure the safety of stored samples.
Modular
The system is modular and solutions are customized according to individual requirements
Energy saving
The technology of liquid-subcooling and exhaust-precooling via defrosting water is adopted to save energy
Smart
The PLC control system can automatically control the start and stop of the refrigeration unit, the regular switching between the main and standby machines and the automatic fault switch.
No manual operation is required for refrigeration and defrosting.
