7773118 – Crankcase heater, Belt heater Danfoss

Danfoss Crankcase Belt Heater | 230V

Product Description:

The Danfoss 7773118 is a vital protective component for large-frame Maneurop reciprocating compressors, such as the MT and MTZ 160 series, commonly used in UAE industrial plants. This 230V belt heater is designed to be installed around the lower base of the compressor shell. Its primary role is to maintain the oil temperature during off-cycles, ensuring that refrigerant does not migrate and condense into the crankcase. In the specific climate of Dubai, where daytime heat transitions into cooler, humid nights, the 7773118 prevents the oil from being diluted, thereby ensuring maximum lubrication and preventing “liquid slugging” when the system restarts. Its high-quality heating element and adjustable metal belt ensure a snug fit and efficient heat transfer for years of service in the Middle East.

Key Features & Benefits:

• Optimized for Large Compressors: Specifically sized to fit the largest Maneurop compressor shells found in UAE commercial installations.
• Superior Oil Protection: Prevents refrigerant migration and oil foaming, ensuring the longevity of mechanical parts in Dubai’s high-load systems.
• Easy and Secure Mounting: Features a durable metal clamping mechanism that stays tight despite the vibration of UAE plant room equipment.
• Reliable 230V Operation: Standard voltage compatibility for UAE control panels, making integration simple for maintenance teams.
• Heavy-Duty Construction: Built with materials that resist high temperatures and the dusty outdoor conditions typical across the UAE.

FAQs:

• Q: Why do I need the 7773118 in a hot climate like the UAE?
• A: Even in hot climates, the compressor must be warmer than the rest of the system to prevent refrigerant from moving to the oil. The 7773118 provides that crucial temperature differential in UAE systems.
• Q: Is this heater easy to replace by UAE service teams?
• A: Yes, the belt design allows for quick installation or replacement without needing to open the refrigeration circuit, a major advantage for UAE field service.
• Q: Can this be used for both MT and MTZ compressors in Dubai?
• A: Absolutely, as long as the compressor shell size matches the belt’s length, it provides effective protection for both series in the UAE.
