Bitzer sets the bar for sustainability and energy efficiency in HVACR

Bitzer

Energy-efficient systems for natural refrigerants are currently an emerging topic in the entire industry. The main challenge of the future will be to raise HVAC&R systems to an even more eco-friendly and energy-efficient level.

BITZER, with expertise in products for R290 (propane), is the only company offering a comprehensive compressor portfolio for this refrigerant – including reciprocating, screw and scroll compressors. Whether for heat pumps, air conditioning or process and IT cooling, the new ORBIT PRO scroll compressors open a wide range of sustainable applications.

BITZER expands its ORBIT scroll compressor series with a version specially designed for the future-proof refrigerant R290 (propane). With evaporation temperatures between –30°C and 30°C and condensing temperatures between 10°C and 80°C, the compressors are therefore also suitable for the combined use in systems for reversible heat pumps. The ORBIT PRO series delivers a cooling capacity of between 16 and 64 kW and a heating capacity of between 21 and 82 kW* and is available in displacements between 19.8 and 77.2 m3/h at 50 Hz.

Reciprocating compressors of BITZER are also specially adapted to operate with R290 (propane). The BITZER ECOLINE P series can be used in various applications and is designed to achieve high energy efficiency and low operating costs. This is accomplished through features such as optimised working valves´ configuration and internal gas flow, the combination with the mechanical capacity control VARISTEP for high efficiency at both whole and part load, or the variable speed control with the frequency inverters VARIPACK.

Optimising compressor operation: IQ MODULE and other electronic components

BITZER IQ MODULE CM-RC-02 for ECOLINE reciprocating compressors

The IQ MODULE simplifies and optimises compressor installation, operation, maintenance, and retrofitting. This results in time and cost savings for the system operator, the installer, and the planner and offers a new world for operating the installed compressor accessories and new digital services. All reciprocating compressors of the C3 to C8 series manufactured at the Schkeuditz factory in Germany come with the latest generation of the IQ MODULE CM-RC-02.

In addition to monitoring the compressor’s critical operating parameters, the IQ MODULE can also operate compressor motor protection and the oil heater and keep an eye on the discharge gas temperature and oil supply. The high-pressure switch can be connected directly to the compressor module. The IQ MODULE CM-RC-02 requires the switch signal from the superior system controller to activate the compressor. Additional functions included in the optional range of services for BITZER reciprocating compressors – for example, capacity control, oil level monitoring and control, and liquid injection – can be electrically connected to the IQ MODULE, which not only simplifies switch cabinet wiring but also reduces the number of control outputs required.
