Danfoss Crankcase Belt Heater | 75W, 230V

Product Description:

The Danfoss 7773117 is an essential protective component for high-capacity Maneurop reciprocating compressors operating in the UAE‘s demanding climate. This 75W, 230V heater features a flexible belt design that wraps securely around the compressor’s base, providing consistent heat to the oil sump. By maintaining the crankcase temperature above the system’s ambient temperature, it effectively prevents refrigerant from condensing in the oil during off-cycles. This is vital in Dubai’s fluctuating coastal humidity, as it eliminates oil dilution and ensures that the compressor starts with pure, effective lubricant every time. Its durable construction is built to withstand the intense heat and dusty environments typical of UAE outdoor installations.

Key Features & Benefits:

• Higher Heating Capacity: 75W output provides the extra warmth needed for larger compressor housings in the UAE.
• Protects Lubrication Integrity: Prevents refrigerant migration, ensuring that oil “foaming” does not occur at start-up in Dubai systems.
• Universal Fit for Large MT/MTZ: Designed to fit snugly on a range of larger Maneurop compressor models used in the UAE.
• Weather-Resistant Design: Features high-grade insulation and a secure clamping mechanism for long-term reliability in UAE outdoor conditions.
• Extends Compressor Life: Minimizes mechanical wear on bearings and valves by ensuring perfect lubrication from the first second of operation.

FAQs:

• Q: When should I choose the 75W (7773117) over the 65W version in the UAE?
• A: The 75W model is generally specified for larger compressor shells (like MT/MTZ 100-160) where more surface area needs to be heated in the UAE.
• Q: Is it okay to use a 230V heater in a UAE industrial site with 400V power?
• A: Yes, the heater is typically wired into the control circuit (L-N) or a separate 230V feed, which is standard practice for UAE HVAC panels.
• Q: Does this heater help with energy efficiency in Dubai?
• A: While it consumes 75W, it saves significant energy and costs in the long run by preventing compressor failure and maintaining system efficiency in the UAE.
