YANMAR HEAT PUMPS AND CHILLERS
HEATING AND COOLING WITH NATURAL REFRIGERANTS
With YANMAR propane and isobutane systems, you benefit from modern technology that combines cost-effectiveness with refrigerant solutions designed to meet current and foreseeable regulatory requirements. Our systems are engineered for efficient operation and use naturally occurring refrigerants with a very low global warming potential.
THE NATURAL REFRIGERANTS
For many years, partially and fully halogenated refrigerants were widely used in refrigeration and air-conditioning systems. Despite their technical advantages, however, their impact on the stratospheric ozone layer and the climate has increasingly become a concern. As a result, the use of fluorinated refrigerants in Europe has been subject to progressively stricter requirements and restrictions, including tighter rules on leak prevention and the phase-out of refrigerants with a particularly high global warming potential (GWP).
As natural refrigerants, propane (R290) and isobutane (R600a), with GWPs close to zero, have a significantly lower impact on the climate. With YANMAR heating and cooling systems, you benefit from climate-friendly solutions with excellent long-term prospects.

With our heating and cooling solutions, we aim to make a meaningful contribution to the transition towards more climate-friendly energy systems. By combining innovative technology with natural refrigerants such as propane and isobutane, we help reduce environmental impact and support a more sustainable future.
Highest flexibility -
Performance for
every need
Our heat pumps and chillers provide precisely tailored performance for a wide range of applications.
High
reliability
At our in-house YANMAR manufacturing facility, our experienced engineers develop new solutions based on proven technology. As a result, our systems are designed for high reliability and efficient operation.
Cost &
resource efficiency
YANMAR stands for high-performance, cost-effective systems. Our heat pumps and chillers continue this tradition with efficient operation, reliable performance and low operating costs.
Comprehensive
control
Our systems are equipped with control technology developed and programmed in-house. Continuous recording of operating data enables convenient remote diagnostics and monitoring.
LOW REFRIGERANT CHARGE
Our systems are designed to operate with low refrigerant charges. By transferring heating or cooling energy via a secondary medium, even longer pipe runs can be implemented without having to increase the refrigerant circuit accordingly.
SAFETY
BY DESIGN
Our systems using flammable natural refrigerants incorporate a comprehensive safety concept. Depending on the system design, this includes measures such as enclosed machine housings, gas detection and appropriately designed ventilation systems to support safe and reliable operation.
Factory-tested
quality
Each machine undergoes a complete function test on our in-house test bench before delivery.
Easy
maintenance
Serviceability is taken into account from the very beginning of the design process. Components are arranged for easy access, helping to simplify operation, inspection and maintenance.
