Hydro-Pro - Compressor Crankcase Heating Belt 230V 35W 430mm - 7020270

Hydro-Pro – Compressor Crankcase Heating Belt 230V 35W 430mm

This is a genuine Hydro-Pro replacement compressor crankcase heating belt for the Hydro-Pro Inverter heat pump (Type Xp26Dcsi+). Rated at 230V and 35W, it wraps around the compressor shell and keeps the lubricating oil warm during standby and off-cycles, preventing refrigerant from migrating into the oil sump. At 430mm in length with a 12×7 plug connector, it is a direct, like-for-like replacement for the original part.

Why Your Heat Pump Needs It

When a pool heat pump is switched off, refrigerant can migrate and condense in the coldest part of the system — typically the compressor crankcase. This dilutes the lubricating oil, leading to increased friction, bearing wear, and potential compressor failure on the next start-up. The crankcase heating belt keeps the compressor above the refrigerant saturation temperature during idle periods, ensuring the oil remains uncontaminated and the compressor starts cleanly every time.

Compatibilité

This heating belt is a factory spare part designed specifically for the Hydro-Pro Inverter heat pump, Type Xp26Dcsi+. Always verify your heat pump model and the original part number before ordering to ensure a correct fit. If you are unsure, consult the heat pump’s wiring diagram or contact a qualified technician.

Installation

The belt is fitted by wrapping it around the lower section of the compressor shell and securing the 12×7 plug connector to the unit’s wiring harness. Replacement should be carried out by a qualified refrigeration or pool heating technician, as work on the heat pump’s internal components involves mains voltage and refrigerant-circuit components.
