Are you dealing with a persistent refrigerant leak in your Thermo King unit? Is your X426 or X430 compressor losing pressure, struggling to maintain temperature, and driving up your operational costs? For engineers and fleet managers, a failing shaft seal isn't just a minor part failure—it's the root of systemic inefficiency, unexpected downtime, and costly refrigerant loss. When that critical seal wears out, it compromises the entire refrigeration system's integrity.
