24V Variable-Displacement Compressor X430/X426 – OEM Replacement for Thermo King & Carrier Transicold | Bus & Reefer AC
- Overview
- Recommended Products
- Stroke modulation: the swash-plate angle adjusts continuously to load demand.
- At setpoint, the compressor settles into a low-stroke cruise instead of cycling on/off.
- Less clutch cycling = less wear on clutch and belt drive components.
- Lower average torque demand = fuel savings on the engine side.

Variable Displacement: Power Only When Needed
The X430 is a variable-displacement compressor — a small-shaft, 24V unit engineered for Thermo King and Carrier Transicold refrigeration and bus air-conditioning systems. Unlike a fixed-displacement unit that pumps full volume at all times, the X430 modulates its stroke to match the cooling load.
The payoff is measured in fuel and wear: approximately 10% fuel savings and 15–20% electrical savings under part-load conditions, plus cabin temperature held within ±0.5 °C – the stability that perishable cargo and passenger comfort both demand.
