Description

A glass tube heater for refrigerators is a tubular heating element designed to prevent frost buildup on the evaporator, drain pipe, or door frame. Encased in a heat-resistant glass sheath, it ensures uniform heat distribution and long-lasting performance. These heaters are commonly used in automatic defrost systems to maintain efficient cooling.

Applications:

• Refrigerator evaporator coil defrosting

• Drain line frost prevention

• Commercial and industrial freezers

• Display cases and cold storage units

Features:

• Heat-resistant glass tube: Ensures durability and safety in moist environments

• Even heat distribution: Promotes efficient defrost cycles

• Energy efficient: Low power consumption

• Moisture and corrosion resistant: Ideal for refrigeration environments

• Custom lengths and wattages available

Specifications:

• Voltage: 110V / 220V AC

• Power Rating: 10W – 200W (model dependent)

• Length: Typically 150mm to 1000mm

• Outer Material: Borosilicate or quartz glass

• Temperature Range: -30°C to +120°C

• Mounting Type: Clip or bracket mount

• Ingress Protection: IP55 or higher (depending on model)

Questions:

1. Where should a glass tube heater be installed in a refrigerator for maximum defrost efficiency?

2. How do glass tube heaters compare to aluminum or silicone rubber heaters in refrigeration systems?
