KAISAI KHC 30 Monoblock – Powerful all-in-one heat pump for sustainable climate control

The KAISAI KHC 30 Monoblock is a high-performance air-to-water heat pump designed for maximum efficiency, easy installation, and versatility. Thanks to its monoblock design, all refrigeration and hydraulic components are housed in the outdoor unit. This simplifies installation and eliminates the need for refrigerant piping within your home.

The KHC 30 provides reliable heating, cooling, and hot water. Thanks to its inverter technology and intelligent control system, the heat pump always operates at the most efficient level, tailored to the building's current heating or cooling needs.

Key Features

All-in-one unit

All essential components—circulation pump, expansion vessel, safety valve, flow sensor, three-way valve, and air vent—are fully integrated into the outdoor unit. This reduces installation time, accelerates commissioning, and ensures a neat and tidy installation.

Multiple operating modes

The heat pump supports up to 6 modes:

• Heating

• Cooling

• Hot tap water

• Heating + hot water

• Cooling + tap water

• Automatic mode

This allows one system to meet diverse comfort needs.

High efficiency and quiet operation

The KHC series achieves high efficiency thanks to a modern inverter compressor and optimized heat exchanger technology. Even at outdoor temperatures as low as -25°C, the system remains reliable and efficient. Its quiet operation makes the unit suitable for both residential areas and projects where noise regulations are important.

Wide temperature range

• Heating water temperature: 25 – 65 °C

• Cooling water temperature: 5 – 25 °C

• Hot tap water temperature: 40 – 60 °C

• Outside temperatures:

  • Heating: -25 to +35 °C

  • Cooling: -5 to +46 °C

  • Tap water production: -25 to +43 °C

This ensures high performance all year round, in both mild and extremely cold climates.

Smart control

The heat pump comes standard with a Wi-Fi module. Using the mobile app, you can:

• set the water temperatures,

• monitor energy consumption,

• manage modes and zones,

• adjust settings,

• receive notifications and status information.

There is also a USB port for software updates and configuration.

Flexible expansion

The system supports the Modbus RTU protocol and can be connected in:

• cascade systems (up to 6 units),

• larger installations (up to 16 units via communication module).

This makes the KHC 30 suitable for residential, commercial and utility projects.

Robust construction

Thanks to durable materials, corrosion-resistant fins, and a weatherproof casing, the heat pump is designed for long-term, intensive use. The design minimizes maintenance and extends the system's lifespan.

Environmentally friendly coolant

The KHC series uses R32 refrigerant, which has a lower environmental impact and operates more efficiently than older refrigerants.
