Refrigeration / Home Appliance Components
Hot Tubes
High-pressure discharge lines utilizing compressor heat for anti-condensation systems. A key element protecting refrigerators against corrosion, moisture, and mold under the gaskets.
- Material: Steel / Copper
- Diameters: 4.0 mm - 4.76 mm
- Cleanliness: Compliant with DIN 8964
- Resistance: High pressures and corrosion
Why Is a Hot Tube Essential?
Anti-Condensation
Heating the refrigerator frame prevents water vapor from condensing at the interface of the gaskets and the housing, eliminating the "sweating" problem of the appliance.
Gasket Protection
Heat from the tubes maintains full elasticity of the gaskets, preventing them from freezing to the housing and experiencing premature wear.
Specifications and Cleanliness Standards
| Technical Parameter | Value / Standard |
|---|---|
| Tube type | Steel, galvanized, copper |
| Internal cleanliness | DIN 8964 Standard (free of moisture and solid particles) |
| Surface protection | Resistance to moisture and PU foam |
| Operating temperature | Up to 80°C (section directly downstream of the compressor) |
| Application | Frame heater, condenser discharge lines |
| Main customers | Samsung and other home appliance market leaders |
Why Is DIN 8964 Cleanliness Crucial?
In refrigeration systems, hot tubes operate under the highest pressure. Even the smallest solid particle could lead to:
- Blockage of the capillary tube: incapacitating the refrigerator.
- Accelerated valve wear: inside the compressor.
- Chemical reaction with the refrigerant: system acidification.
SINTUR guarantees 100% internal cleanliness thanks to rigorous storage and processing procedures for steel tubes.
