BITZER Brings Expanded CO₂ Portfolio, ECOLITE Units and Retrofit Kits to Chillventa 2026

BITZER will use its Chillventa 2026 appearance to present a broadened natural-refrigerant product range, retrofit solutions for installed systems, and a new interactive exhibition format. The stand, designed around the motto "SHAPING THE FUTURE WITH YOU", will occupy position 303 in Hall 1 at the main entrance to Nürnberg Messe from 13 to 15 October 2026.

Regulatory pressure and supply-chain uncertainty

Geopolitical developments, evolving F-Gas Regulation requirements in Europe, and the Kigali Amendment's staggered global timelines are making investment decisions in refrigeration, air conditioning and heat-pump systems increasingly complex. Regional differences in refrigerant availability, infrastructure and expertise add further layers of uncertainty. Against this backdrop, BITZER positions its "SHAPING THE FUTURE WITH YOU" approach as a combination of future-proof products and what the company calls #greencompetence – personal consultation, services and application-specific expertise delivered across the full product lifecycle through its global service network and local contacts.

New products for natural refrigerants

The product highlights at the stand span several refrigerant families:

• CO₂ (R744): The ECOLINE series is being expanded with new 6-cylinder reciprocating compressors for transcritical CO₂ applications, built on the existing ECOLINE construction principles of energy efficiency, robust design and long-term parts availability. In addition, new air-cooled ECOLITE CO₂ condensing units offer a compact plug-and-play design suitable for both medium- and low-temperature applications, with advanced capacity control for efficient operation across all climate zones.
• Propane (R290): A comprehensive portfolio with low GWP values, application-specific safety concepts and high efficiency.
• Industrial ammonia (R717): A similarly comprehensive portfolio combining low GWP, application-specific safety concepts and high efficiency.
• Screw compressors: The next generation of BITZER screw compressors will be presented for the first time, developed with a stated focus on specific applications and customer requirements.

PERFORMANCE KITS: retrofitting existing ECOLINE and ECOLINE PRO compressors

For installed ECOLINE (HFC/HFO) and ECOLINE PRO (hydrocarbon) reciprocating compressors, BITZER will exhibit PERFORMANCE KITS centred on the IQ MODULE CM-RC-02, which mounts directly on the compressor terminal box. Depending on the selected kit, the module adds:

• ENERGY KIT – retrofits VARISTEP (CRII) mechanical capacity control to optimise part-load operation.
• OPERATIONAL SAFETY KIT – adds protective functions to increase system availability.
• CONNECTIVITY KIT – provides access to digital monitoring and service concepts via the BEST SOFTWARE and the BITZER Digital Network.

The kits are designed to let operators adapt existing systems to new operating conditions without complex modifications to the system design.

BITZER Arena: a new hands-on format

For the first time at Chillventa, BITZER will operate the BITZER Arena, a dedicated space designed for planners, consultants and installers. The format pairs hands-on stations with personal exchange and concrete examples covering the full lifecycle – from planning and installation through operation, modernisation and retrofit – with the stated aim of reducing complexity and simplifying decision-making.

AWA joins the BITZER stand

Armaturenwerk Altenburg (AWA), the long-established Thuringian component manufacturer that has been part of the BITZER Group since 2013, will be integrated into the BITZER stand for the first time. AWA's portfolio for wholesalers and refrigeration applications includes valves, sight glasses, flanges, actuators and sensors.
