To understand the service life of cold storage heater element, let’s first understand the common causes of heating tubes damage:
1. Bad design. Including: the surface load design is too high, so that defrost heating tube can not bear; Select the wrong resistance wire, wire, etc. can not withstand the rated current; The wrong choice of pipe or wire can cause the operating temperature to be unbearable; It does not consider the context of use and ignores product details.
2. Improper manufacturing. Including: impurities in the insulation layer during the processing lead to leakage of defrost heater element; Uncontrolled processes can lead to differences in resistance, which can affect actual power; Improper water excretion and improper sealing can cause water vapor to enter the internal insulation layer.
3. Improper use. Includes: Heating tubes for metal molds or liquid environments for air dry burning; Use non-rated voltage power supply; Excessive bending of wires without special design; Unauthorized change of wire, affect insulation effect, etc.
The above improper operation may lead to short circuit of equipment, burning of cold room heating tube and rupture of electric heating tube. These problems may occur after a week of use, or they may hide potential dangers and wait for a moment to flare up. However, if it is a refrigerator defrost heater tube that has been properly designed, manufactured and used, it will not be a problem if used for more than 5 years under normal working conditions.
So what can manufacturers of electric stainless steel heating tubes ensure for their customers?
1. Provide good product design. Design for use by the customer, with as much consideration as possible for any use details.
2. Provide high standard of process control. Any damage to SS304 heating tube will cause great loss to customers. The process must eliminate many error-prone links, and product parameters must be tested through multiple checks.
3. Provide professional selection and use advice. To be familiar with the use of customers, more communication and continuous optimization of the product.
