BITZER Unveils Data Center, Heat Pump, and Natural Refrigerant Compressors at Chillventa 2026

BITZER will occupy Hall 1, Stand 303 at Chillventa 2026 in Nuremberg, presenting a product portfolio organised around three transformation drivers of the HVAC+R sector: data center cooling for AI and high-performance computing workloads, large-scale heat pumps for decarbonised heating, and an expanded range of natural refrigerant solutions. The company's motto for the show is "SHAPING THE FUTURE WITH YOU." Martin Büchsel, Chief Sales and Marketing Officer at BITZER, stated that the company's goal across all three areas is to secure the success and growth of its customers and partners, supporting them with the right products, application expertise, and a global network.

Data center cooling: HELICOM CS60

Rising power densities in server racks and higher heat loads from AI applications and HPC are increasing demands on data center cooling. Rainer Große-Kracht, Vice-Chairman of the Management Board and Chief Technology Officer at BITZER, described the new HELICOM series as one of the most significant developments in the company's screw compressor technology, built on more than four decades of experience in this field.

Key specifications of the HELICOM CS60 series:

• Supply temperatures of up to +45 °C, supporting cooling systems for the latest generation of AI chips
• Standardised cooling platforms deployable consistently across locations and climate zones
• Wide application limits and support for established low-GWP refrigerants
• Optimised rotor profiles for efficient full and part load operation, supporting demanding PUE targets
• Suited to low-lift operation at low ambient temperatures typical of modern data centers
• Integrated IQ MODULE for high operational reliability and availability

Large-scale heat pumps: CSH2T series

Decarbonisation of heating remains one of the greatest challenges of the energy transition. Large-scale heat pumps enable the efficient use of ambient and waste heat for industrial applications, district heating networks, and reversible heating and cooling systems. BITZER is working to extend the application range of its heat pump components to condensing temperatures of more than +140 °C, drawing on more than 50 years of experience in heat pump applications.

The CSH2T series, a highlight at Chillventa 2026, comprises compact screw compressors developed specifically for high-temperature heat pumps:

• Fluid outlet temperatures of up to +120 °C
• Heating capacities of up to approximately 1.1 MW per compressor
• Suitable for industrial heating processes and district heating networks
• Backed by a comprehensive portfolio of compressors, heat exchangers, and frequency inverters

Natural refrigerants: expanded portfolio

BITZER is presenting several additions to its natural refrigerant range at the show:

• ECOLINE CO₂ series – new 6-cylinder reciprocating compressors added, creating a scalable portfolio from 2- to 8-cylinder units for transcritical CO₂ applications
• ECOLITE CO₂ series – air-cooled condensing units for medium and low temperature applications with a plug-and-play concept for easy entry into CO₂ systems
• ORBIT PRO series – scroll compressor versions optimised for propane in heat pump, air conditioning, process cooling, and IT cooling applications
• ACP SINGLE – a single-compressor unit based on the OS.A95 screw compressor, enabling flexible and redundant system concepts for demanding industrial ammonia refrigeration

BITZER Arena

For the first time, BITZER is demonstrating in the BITZER Arena how products, know-how, digital tools, and services interact across the entire product life cycle, presenting its #greencompetence in a practical and tangible format. The company frames the arena around its "WE ARE BITZER" concept, positioning itself as a long-term partner rather than a product supplier.
