Description

Defrost heaters are used to melt the ice formation in refrigeration equipment. They are formed due to defrost water which turns to ice inside a below freezing cold room, collected in trays or on defrost line.

We manufacture the defrost heater that fits your needs. Used by the commercial refrigeration industry as defrost heaters in frozen food display cases. Other application also include air and radiant heating.

Tubular defrost heater element is mainly used in evaporator heating defrosting, used in refrigerators and commercial refrigeration such as chiller, freezer display cabinet, kitchen refrigerator, refrigerated container unit, etc. It generally use magnesium oxide as the insulation material, stainless steel or Incoloy alloy used for the tube, using neoprene or silicone rubber sealing mold head protection. According to customer requirements, we can design different length of lead wire and end connection terminals, additional temperature controller and fuse fuse.

To effectively use Defrosting Heaters in display cabinets and refrigerators, follow these steps for proper installation, operation, and maintenance:

1. Installation

2. Operation

3. Maintenance and Monitoring

4. Troubleshooting

5. Upgrading or Replacing

Due to the characteristics of high indoor humidity, low temperature and frequent thermal shock during the operation of refrigeration equipment, defrosting heater elements are generally based on tubular electric heating elements, using high-quality modified magnesium oxide as filler and stainless steel as shell. After tube reduction, the wiring terminals are sealed by special rubber pressing. Enable the electric heating element to be used normally in the refrigeration equipment.

Regarding the connection, the defrost heater which is marked with Y is star connections, and Y must be connected to the center line. Those not marked are all Δ triangle connections. For instance, the heating element of a cold air blower is usually 220V. One end of each heating tube is connected to the live wire, and the other end is connected in parallel to the neutral wire. In addition, the input power marked on the outer shell of the heating tube is generally the rated power of the heating tube.

Frost buildup in refrigeration will influence the efficiency and increase energy consumption. Aluminum tube heaters are an effective solution to mitigate this issue.Regular and thorough defrosting will prevent excessive frost accumulation.

Aluminum tubular defrost heaters prevent ice blockages that can restrict airflow and reduce cooling efficiency.

This ensures that the refrigeration unit operates at optimal performance levels.

Refrigerator defrost heater is designed for defrosting hard of various kinds of freezer,refrigerator. Defrost heater is adopted the stainless steel as the base material. Any shape to the user's requirements. This properties of the product are defrosted effectually,the insulating resistance is excellent,corrosion-resistant,resist and wear out. Defrost heater is safe and reliable to carry the sealed dampproof performance of the end which obtained the national patent.

The following points need to be pay attention to when refrigerator defrosting heater works:

1. Since the refrigerator defrost heater is connected to the thermostat switch and the heater operating line, the heater failure will affect the refrigeration effect of the refrigerator, and it needs to be checked and replaced in time.

2. The operation time and interval of the refrigerator defrost heater are automatically adjusted, so when the defrosting is incomplete or repeated, it is necessary to timely detect the operating status of the defrosting heater.

3. In order to keep the inside of the refrigerator dry, it is necessary to clean the refrigerator every once in a while to prevent the growth of microorganisms such as bacteria and mold inside the refrigerator.

We manufactures the defrost heater that fits your needs. Used by the commercial refrigeration industry as defrost heaters in frozen food display cases. Other application also include air and radiant heating.

If the equipment installed with the defrost heater element does not work properly, the following items can be checked:

1, check whether the connection line of the defrost heater element is broken, or wrong connection;

2, check if the defrost element burned or leakage;

3. Check if the terminal in the junction box of the cooler has leakage;
