Description
Trane HTR6605 Sump Heater Overview
The Trane HTR6605 is a 460-volt, 100-watt sump heater engineered to protect compressor oil from refrigerant migration during off-cycle periods. By maintaining the oil sump at an elevated temperature, this heater helps prevent liquid refrigerant from diluting or displacing compressor oil — a leading cause of compressor damage and premature failure. Designed as a genuine Trane OEM replacement part, the HTR6605 ensures a precise fit and reliable performance in compatible Trane equipment.
Key Features
- Operating Voltage: 460V
- Wattage: 100W
- Designed to prevent refrigerant migration into compressor oil sump
- Helps extend compressor service life by maintaining proper oil viscosity
- Genuine Trane OEM replacement part for accurate fitment
- Ideal for use during compressor off-cycles in commercial HVAC applications
Why Sump Heaters Matter
During extended off periods, refrigerant can migrate to the compressor oil sump, causing oil dilution and poor lubrication at startup. A properly functioning sump heater keeps the oil warm enough to prevent this migration, protecting the compressor from wear, slugging, and potential failure. The Trane HTR6605 delivers consistent, low-wattage heat to maintain optimal oil conditions.
Application
- Replacement sump heater for compatible Trane commercial HVAC and refrigeration equipment
- Suitable for systems operating on 460V power supply
