30RHM

Efficient air‑to‑water heat pump for reliable heating and cooling in residential and light‑commercial applications
The Carrier 30RHM air source heat pump delivers dependable, energy‑efficient performance using advanced variable‑speed technology. Designed to integrate seamlessly with modern hydronic systems, it provides stable comfort, reduced energy consumption, and quiet operation across a wide range of operating conditions.

The Carrier 30RHM is an air‑to‑water heat pump engineered for space heating and cooling through hydronic distribution systems. By extracting renewable energy from ambient air, the system offers a sustainable alternative to conventional heating solutions while maintaining consistent comfort and efficiency.

30RHM

Efficient Inverter Design

Variable Frequency Drive with 15-100% stepless capacity control, and inverter driven condenser fans - for precise temperature control & energy conservation

High operating temperatures

Operating temperature in cooling mode: -20 to +55ºC Operating temperature in heating mode: -26 to +55ºC

Low noise operation

Low noise operation for a silent neighborhood. Noise levels can be as low as 50 dB(A) in partial load operation.

Balanced control for high energy efficiency

Partial load operation is highly optimized. When multiple modules are combined, the frequency of each compressor is intelligently controlled, so that the system operates in an energy efficient manner

Free master Module Design

Any of the single unit can operate as the master once connected with the wired controller. This avoids the issue of whole system fail to work when the fixed master unit malfunctions.

Integrated Heat Pump Control

Built‑in control logic manages compressor modulation, water temperature regulation, and heating / cooling operation.
Variable‑speed operation adapts output to real‑time demand, improving comfort stability and efficiency.

Hydronic System Integration

Designed to integrate with common air‑to‑water hydronic systems, including:
Underfloor heating
Fan coil units
Radiators
Buffer tanks
Domestic hot water tanks (when configured)

External Control Compatibility

Compatible with external room thermostats and temperature sensors for space control and system feedback.
Supports system‑level control strategies implemented via external controllers supplied as part of the installation.

Energy‑Efficient Operation

Control strategy prioritizes part‑load efficiency, reducing cycling and optimizing seasonal performance.
Suitable for standalone operation or inclusion within a broader hydronic plant.
