Electric control box for cold store and freezer room refrigeration system

详情

Features:

Such electric control box can support the wide range of voltage, the refrigeration and defrosting are all automatical operation.

1. Using the voltage monitor to monitoring the voltage, which can be set in a range of value, such as, if the voltage is below **0V or over **0V, the control circuit can automatically break to protect the machine;

2. Also it has the function of phase sequence protection, phase missing protection. Equipped with motor protector and thermal relay to avoid the over current, overload,

3. Starting running with Delta starting;

4. One refrigeration condensing unit with one air cooler;

5. Interlock control circuit between refrigerating and defrosting, while refrigerating, the defrosting circuit is automatically cut off; while defrosting, the refrigerating circuit is automatically cut off. Such protection is to avoid mistake operating.

6. High and low pressure control circuit prevents the refrigeration equipment away from high pressure attacks,

7. Equipped with oil pressure control circuit to protect the compressor from damage due to lack of oil;

8. Microcomputer temperature controller with digital screen. Compressor starts up in default 3 minutes of delay time between stopping and starting up, air cooler fans starts up in 1~5 minutes delayed after compressor start-up to save more power.

9. Running fault indication light.

Any other size items, function can be customized.
