Split Type Air Conditioner: Flexible Cooling for Machinery Cabs and Compact Spaces
A split type air conditioner separates the evaporator and condenser into two connected units, making it ideal for machinery cabs, compact vehicles, and installations with limited engine-bay space. This guide explains how split type AC works, the specifications that matter for off-road and industrial applications, and why OEMs choose split designs for custom HVAC integration.
Quick Answer
- A split type air conditioner divides cooling into an indoor evaporator unit and an outdoor condenser unit, connected by refrigerant lines.
- Kangbao split type AC units run on 12V or 24V DC, deliver 3–5 kW cooling capacity, and use R134A refrigerant with flexible hose routing.
- Split designs are preferred when engine-bay space is tight, cab vibration must be isolated from the compressor, or custom mounting is required for specialty machinery.
How Does a Split Type Air Conditioner Work in Machinery?
A split type air conditioner for off-road machinery consists of two main assemblies. The indoor unit (evaporator, blower, and filter) mounts inside the operator cab, while the outdoor unit (condenser, compressor, and fan) installs in the engine compartment or on the machine frame.
Refrigerant lines run between the two units, carrying R134A through the closed cooling cycle. This separation allows engineers to place the heavy, vibrating compressor away from the cab, reducing noise and vibration for the operator. It also frees up cab interior space and simplifies maintenance access to both assemblies.
Kangbao split type AC systems are engineered with reinforced hoses rated for vibration, dust, and temperature extremes from -10°C to +55°C. The modular design supports custom line lengths and mounting brackets for OEM integration on excavators, loaders, tractors, and specialty vehicles.

For OEM partners, Kangbao offers split type AC configurations with electric or engine-driven compressors, CAN-bus control panels, and multi-speed blowers. Our split systems are exported to Turkey, Russia, South Africa, and the Americas for integration into excavators, telehandlers, and agricultural machinery.
FAQ
What is the difference between a split type air conditioner and a monoblock unit?
A split type air conditioner separates the evaporator and condenser into two units connected by refrigerant lines, allowing flexible placement and reduced cab noise. A monoblock unit houses all components in a single enclosure, which is simpler but requires more installation space and transmits more vibration into the cab.
Can a split type air conditioner be retrofitted to existing machinery?
Yes. Kangbao split type AC kits include mounting brackets, pre-charged refrigerant lines, and wiring harnesses designed for retrofit installation. The key requirements are adequate engine-bay space for the condenser unit, a 12V or 24V power source, and a sealed or partially sealed cab for effective cooling.
