Danfoss PTC Crankcase Heater | 27W | 120Z0459

Product Description:

The 120Z0459 is a specialized heating element used to maintain compressor oil temperature during the off-cycle. Utilizing PTC technology, this heater is self-regulating; as the temperature rises, its resistance increases, effectively lowering its power consumption. In the UAE, while daytime heat is intense, cooling systems in air-conditioned plant rooms or those experiencing night-time temperature drops are prone to refrigerant migration. By keeping the oil warm, the 120Z0459 ensures that refrigerant does not condense in the crankcase, preventing “liquid slugging” and ensuring a smooth, lubricated start every time. Its compact design makes it a vital replacement part for maintaining the longevity of Danfoss scroll compressors in Dubai and Abu Dhabi.

Key Features & Benefits:

• Self-Regulating PTC Technology: Automatically adjusts heat output based on ambient temperature, preventing overheating and saving energy.
• Prevents Liquid Slugging: Ensures refrigerant stays in a vapor state, protecting internal compressor components from mechanical damage during startup.
• Optimized for UAE Conditions: Provides essential protection for compressors during standby periods in high-humidity or climate-controlled environments.
• Highly Reliable: No moving parts and a durable heating element ensure a long service life with minimal maintenance.
• Easy Installation: Designed for a precise fit into the heater well of compatible Danfoss compressors, ensuring efficient heat transfer to the oil.

FAQs:

• Q: Why is a 27W heater like the 120Z0459 used in the UAE?
• A: Even in hot climates, refrigerant moves to the oil when the compressor stops. This heater prevents that migration, which is critical for the long-term health of HVAC systems in Dubai.
• Q: Does this heater need a separate thermostat?
• A: No, because it is a PTC heater, it self-regulates its temperature without the need for external thermostat controls.
• Q: Can this be used on a wide range of voltages in the UAE?
• A: Yes, the 120Z0459 is designed to operate across a broad voltage range, making it highly versatile for various UAE electrical installations.
