As industries across Europe transition to low-carbon operations, the electrification of heat is becoming a critical strategy. Industrial heat pumps offer a clean, efficient, and scalable solution for generating process heat and district heating. FILTER provides industry-leading heat pump systems from Oilon and Heaten, designed to meet the technical and performance demands of industrial and utility clients.
1. Industrial heat pump solutions
FILTER’s portfolio includes high-performance heat pump systems tailored for various industrial applications, from medium-temperature hot water to large-scale steam production.
1.1. Why Oilon?
Oilon ChillHeat systems offer a unique combination of efficiency, reliability, and control features, making them a preferred solution for industrial customers and district heating providers.

- ABB PLC-based automation with auxiliary equipment control functions
1.2. Oilon ChillHeat P-Series
The P-series is designed for mid-sized applications requiring precise control and high outlet temperatures.
Specifications:
- Capacity: 30–450 kW (EN 14511, 0/35)
- Outlet temperature: Up to 120 °C
- Piston compressor technology
- Optional VFDs on up to four compressors
- Compatible refrigerants: R134a, R450A, R513A, R515B, R1234ze, R1233zd
1.3. Oilon ChillHeat S-Series
The S-series serves large-scale heating networks and industrial processes.
Specifications:

- Outlet temperature: Up to 80 °C
- Screw compressor technology
- VFDs as standard
- Broad refrigerant compatibility
1.4. Subcooling efficiency advantage
ChillHeat systems utilize subcooling to increase heat output without added power consumption. This allows up to 15% higher capacity at the same input, significantly boosting overall COP and reducing operating costs.
1.5. Advanced automation & connectivity
Automation is delivered via ABB PLC with integrated energy metering and remote access capabilities.
Supported interfaces:
- Modbus RTU/TCP
- Profibus
- Profinet
- Bacnet
Remote connectivity is available through Tosibox, supporting remote monitoring, diagnostics, and integration with supervisory systems via OilonONE platform.
2. Steam generating heat pumps
FILTER also provides very high-temperature heat pumps capable of producing direct steam for industrial use. These systems are ideal for process industries looking to eliminate fossil-fuel boilers.
2.1. Heat pumps to decarbonize high-temperature process heat
FILTER partners with Heaten, a pioneer in high-temperature heat pump development with over 13 years of experience. Heaten’s collaboration with the INNIO Group ensures industrial-grade engineering, manufacturing, and lifecycle support.
INNIO supports Heaten with:
- Development and engineering
- Scalable manufacturing
- Global maintenance services
- Application-specific consulting
This partnership enables industrial clients to integrate Power-to-Heat technology into operations with high reliability and long-term efficiency.
2.2. The HeatBooster Technology
The HeatBooster system is a high-capacity, piston-compressor heat pump that delivers saturated steam up to 12 bar and 200 °C, ideal for industrial steam loops.
Key features:
- Robust, compact design
- Efficient part-load operation (down to 20%)
- Compatible with low-GWP refrigerants
- Stable performance in continuous operation
This system enables full electrification of steam generation without compromising process performance or reliability.
2.3. COP performance at high temperatures
COP (Coefficient of Performance) remains a critical metric for assessing heat pump efficiency. Even at high delivery temperatures (e.g., 150 °C), modern systems maintain COP values around 2.2, depending on the source temperature.
This demonstrates that electrified steam production is technically and economically viable, even in energy-intensive applications.
