Product detailed description

High-Efficiency Defrost Tubular Heater for Refrigeration Systems

Our tubular heater is a core heating component for automatic defrosting of refrigeration equipment. Adopting high-quality seamless stainless steel tube shell and high-purity magnesium oxide filling structure, paired with precision resistance heating wire, this heating tube delivers stable and uniform heat output. With insulating sealing treatment and strict power testing, it solves the frosting and ice-blocking problems of evaporators, becoming an essential supporting part for household and commercial refrigeration systems.

Fast Heating & Uniform Heat Dissipation

The optimized internal heating structure ensures rapid temperature rise and uniform heat radiation. It quickly melts frost and ice layers on the evaporator surface during the defrost cycle, thoroughly eliminating ice blockage and poor heat exchange issues. It effectively restores refrigeration efficiency, shortens defrost time, and reduces invalid energy consumption of the equipment.

Anti-Corrosion & Waterproof Sealed Structure

The heater shell adopts high-strength stainless steel material with integrated seamless molding process. Professional end sealing and waterproof insulation treatment prevent moisture and water droplet penetration. It can adapt to long-term low-temperature and high-humidity refrigeration working environments, resisting oxidation, corrosion and leakage risks for stable long-term operation.

High Safety & Insulation Performance

Filled with high-purity insulated magnesium oxide powder, the tubular heater features excellent electrical insulation and pressure resistance. It effectively isolates current conduction, avoiding electric leakage, short circuit and breakdown failures. Strict cold and hot cycle testing ensures no deformation or performance attenuation during frequent defrost switching, improving overall equipment safety.

Stable Power Output & Long Service Life

High-precision heating wire ensures stable power output without overload heating. The structural design avoids local overheating and burnout problems. It supports frequent cyclic defrost work and long-term intermittent operation, with low attenuation of heating performance and ultra-low failure rate, greatly reducing equipment maintenance frequency.

Full Customization & Wide Compatibility

We support full customization of tube diameter, length, power, voltage and bending shape. Multiple installation methods such as straight tube, U-shaped tube and fixed bracket type are optional. Standard and customized specifications can match various refrigeration equipment structures, meeting OEM and ODM personalized production demands.

Easy Installation & Direct Replacement

The tubular heater features reasonable structural design with standard wiring terminals and fixed mounting holes. It is lightweight and easy to install and replace, no complicated modification or debugging required. It is suitable for new equipment assembly and old defrost heater replacement, saving installation and after-sales labor costs.

Wide Application & Global Market Adaptation

Suitable for household refrigerators, chest freezers, vertical display cabinets, supermarket cold storage and various commercial cooling equipment. Reliable defrost performance and cost-effective price make our tubular heaters popular in Southeast Asia, Middle East, Africa and other global markets for bulk wholesale and export orders.

FAQ

Q1: What is a refrigeration tubular heater used for?

A: The tubular heater is a special defrost heating component for refrigeration equipment. It generates stable heat during the defrost cycle to melt evaporator frost and ice, ensuring unobstructed heat exchange and normal cooling efficiency of refrigeration systems.

Q2: What specifications of tubular heaters are available?

A: We provide multiple standard voltages, power ratings, tube diameters and lengths. Straight type, U-type and bracket fixed types are optional. Full customization is supported according to equipment installation size and defrost demand.

Q3: What problems will a faulty defrost heater cause?

A: A damaged tubular heater will lead to insufficient defrosting or complete defrost failure. Thick frost and ice will accumulate on the evaporator, resulting in poor cooling, increased power consumption, and even equipment shutdown failure.

Q4: Is the tubular heater waterproof and insulated?

A: Yes. All heaters adopt fully sealed waterproof structure and high-purity insulation filling material. It has excellent electric leakage prevention and waterproof performance, adapting to humid and low-temperature refrigeration working environments with high safety.

Q5: Can the heater work stably for frequent defrost cycles?

A: Absolutely. Adopting high-quality heating wire and anti-aging sealing material, it resists cold and hot cycle impact. No power attenuation or burnout occurs after long-term frequent switching, maintaining stable defrost performance.

Q6: Do you support custom shaped heating tubes?

A: Yes. We support customized bending shapes, installation positions, wire length and fixing structures. Custom production can be done according to customer drawings and equipment parameters to perfectly match special refrigeration units.

Q7: Is installation and replacement simple?

A: Yes. Standard terminal wiring and reserved mounting holes enable quick installation and direct replacement. No professional debugging is needed after installation, effectively saving maintenance time and labor cost.

Q8: What is your packaging and shipping solution?

A: Each tubular heater is individually packed with anti-collision and shockproof protection to avoid tube deformation and terminal damage. Bulk orders adopt reinforced cartons and wooden pallets for safe global transportation.
