Danfoss Crankcase Belt Heater | 65W, 230V

Product Description:

The Danfoss 7773108 is a critical safety accessory for Maneurop reciprocating compressors operating across the UAE. This 65W, 230V belt heater is designed to be wrapped around the lower part of the compressor housing. Its primary function is to keep the oil in the crankcase warmer than the rest of the system during off-cycles, preventing refrigerant from condensing and mixing with the oil. In the high-humidity and fluctuating night temperatures of Dubai, this prevents “foaming” and ensures proper lubrication at start-up, significantly extending the life of the compressor’s internal components. Its flexible belt design allows for easy installation and a snug fit for optimal heat transfer.

Key Features & Benefits:

• Prevents Refrigerant Migration: Keeps the oil temperature high enough to prevent refrigerant from diluting the lubricant during the UAE‘s cooler nights.
• Ensures Safe Start-ups: Eliminates oil foaming at start-up, protecting bearings and pistons from premature wear in Dubai’s high-load systems.
• Easy Installation: The belt-style design with a secure fastening mechanism ensures a perfect fit for compatible Maneurop compressors in the UAE.
• High-Quality Insulation: Built with durable, heat-resistant materials to withstand continuous operation in harsh UAE outdoor environments.
• Optimal Power Output: 65W provides the ideal amount of heat to maintain oil temperature without excessive energy consumption in UAE facilities.

FAQs:

• Q: Why is a crankcase heater like the 7773108 essential in the UAE?
• A: Despite the heat, night temperatures in the UAE can drop, causing refrigerant to migrate to the cold compressor oil. This heater prevents “liquid slugging” during the next morning’s start-up.
• Q: Should the heater remain on while the compressor is running in Dubai?
• A: Generally, no. It should be wired to be active only when the compressor is OFF to save energy and provide protection during the standby period in UAE systems.
• Q: Can I use this 230V heater on a 400V compressor system in the UAE?
• A: Yes, as long as it is wired into a 230V control circuit or a single-phase supply at your UAE site.
