systems, thus avoiding any competitive overlap with its OEM customers. The company focuses exclusively on the design and supply of components, proposing itself as a reliable and neutral technical partner. This position allows Sanhua to build long- term relationships with builders, off ering integrated solutions that facilitate development and standardisation, without confl icting with their core business.
Complete product packages for R290 Sanhua is already able to cover more than 90% of the components needed for propane plug-in applications. The off er includes fi lters, solenoid valves, TXV, EEV, exchangers, taps, sensors, electronic controllers, inverters and thermostats. The entire range is certifi ed according to PED and CEI EN 60335 standards, including EN 60730-2-89 for electrical safety. The adoption of propane as a standardised solution in
refrigerated plug-ins has led to an explosion in demand in Europe. Sanhua responded by structuring a complete range, with products optimised for performance and cost. Package integration allows OEMs to reduce the bill of materials and facilitate system approval. In the R290 waterloop sector, Sanhua off ers scalable packages with three confi gurations: Basic (with mechanical valve), Smart (with electronic valve and sensors) and Plus (with inverter and digital controller). Electronics are continuously evolving to improve compatibility with key European protocols such as Carel, Dixell, and Danfoss. These solutions are aimed at proximity stores, convenience
stores and retrofi ts of existing systems, where compactness and fl exibility are crucial. Thanks to the high integration of the packages, the installer can reduce commissioning time and costs.
In the mini-rack and CO2 booster units market up to 40
kW, the company is expanding its off er to include all critical components: PEVs, smart sensors, heat exchangers, controllers and safety valves. The CO2
range is expected to be completed
by the end of 2026, with the aim of also covering applications up to 100 kW in transcritical racks.
sector Today, the main challenge is to make CO2
CO2 condensing unit: focus on the sub-40 kW condensing units
competitive with HFO solutions. Costs remain 2–3 times higher, but increased volumes and standardised designs are expected to narrow the gap. Sanhua already off ers key components for these applications: electronic PEV valves with PWM modulation, microchannel and brazed heat exchangers (MCHE), electronic controllers developed with European partners, temperature and pressure sensors, and eff ectively reversible bi-fl ow ball valves.
In particular, PEV stands out for its increased control stability
even under conditions of rapid change in heat load. It is a viable solution for replacing established electronic valves, such as AKVP, with the advantage of a more competitive cost and better sealing at high pressures.

In addition, the company provides pre- and post-sales technical support, including assistance in confi guring and validating packages for specifi c customer needs. With a modular model and a well-established presence
across key sectors, Sanhua positions itself as a driving force in the HVAC-R industry’s transition toward a sustainable and high- performance future.

established names? We try to take advantage of being the newcomer and being able to identify the critical points of existing products and intervene in a targeted way, bringing products to the market that can solve these critical issues. For example, our future CO2
ball valves have been designed to
integrate a service valve instead of a Schrader valve loading access in order to have an increased passage section that avoids the risk of dry ice formation. Some models of CO2
ball valves will integrate a check
valve, while the series for trans-critical applications will have a patented design aimed at the true bidirectionality of the product; these valves will adopt a ball without a hole, typically used during pump down to remove the gas trapped in the ball itself. The goal is to simplify installation and reduce the possibility of technical error by installers while maintaining the very high safety standards of the product even in the event of an accidental increase in internal pressure. A key area of development is electronics. Sanhua is
developing cloud- and IoT-compatible controllers and monitoring systems to meet the needs of retail customers and facility managers. At the same time, the work of certifi cation and validation of the CO2
components continues, with specifi c
attention to European operating conditions. Production localisation also plays a strategic role. With the perspective of the Net Zero Industry Act, Sanhua is evaluating options for production in Europe, in order to ensure resilient supply chains and facilitated access to European incentives. Sanhua does not intend to position itself as a system manufacturer, but as a strategic supplier of components. The commercial approach is based on the product package off erings that provide more favourable conditions for those who adopt integrated solutions. This allows OEMs to: ■Reduce development and certifi cation times; ■Simplify logistical and technical management; ■Increase the standardisation of its products.
Sanhua’s strategic choice to invest in natural
refrigerants, in particular R290 and CO₂, responds to a combination of regulatory, technical and market factors.
