13p semi-closed air-cooled compression condensing unit failure warning instructions
The 13p semi-closed air-cooled compression condensing unit is used in industrial cold processing. After using it for a long time, some problems will arise, Wuxi Guanya (LNEYA) reminds. There is usually a high-pressure alarm on the 13p semi-closed air-cooled compression condensing unit, which is automatically activated in the event of an accident. When we start, we will find that there is a fault indicator that is turned off. Because there is a fault now, it lights up. Some smart technologies ...

How to solve the fault of the ultra-low temperature refrigerator pressure controller?
If the industrial ultra-low temperature refrigerator encounters a controller-related failure during operation, if it is not resolved in time, the pressure controller may be unavailable. The pressure controller plays a very important role in the ultra-low temperature refrigerator group. Because of the pressure exerted between each accessory under the high-efficiency working state, the range is different. In order to reduce the impact of pressure on the ultra-low temperature refrigerator group,...

Refrigeration principle of LNEYA glycol chiller system
Glycol Chiller System SUNDI -10℃ ~ 200℃, as we can tell from its name, it is to use Glycol as the refrigeration agent for the chiller.In the all air environment, because of the low temperature in the outdoors, it is impossible to use a cooling tower to supply the inner area directly with the cold air-conditioner. In addition, the cold air in the outdoors could be used directly as refrigerator source,with glycol as refrigerant, it can introduce the natural cold air into the inner area and su...
