Danfoss 120Z5041 Belt Type 400/460V 70W Crankcase Heater

Description

Danfoss 120Z5041 Belt Type Crankcase Heater Overview

Protect your refrigeration and air conditioning compressors from costly damage with the Danfoss 120Z5041 Belt Type Crankcase Heater. Designed to prevent refrigerant migration into compressor oil during off-cycle periods, this crankcase heater maintains oil temperature and ensures reliable compressor startups — extending equipment life and reducing unplanned downtime.

Key Features

• Belt-type design for secure, consistent contact around compressor crankcase
• Rated voltage: 400/460 Volts for compatibility with commercial and industrial HVAC/R systems
• Power output: 70 Watts for effective crankcase warming
• Prevents refrigerant migration and oil dilution during compressor off cycles
• Helps protect compressor bearings and internal components at startup
• Durable construction built to withstand demanding HVAC/R operating environments
• Easy field installation with flexible belt configuration

Why Use a Crankcase Heater?

During extended off cycles, refrigerant can migrate into the compressor crankcase and mix with the lubricating oil. At startup, this refrigerant flashes off rapidly, causing oil foaming and inadequate lubrication — a leading cause of compressor failure. The Danfoss 120Z5041 crankcase heater keeps the crankcase warm enough to prevent refrigerant absorption, safeguarding your compressor investment.
