Bitzer will be showcasing its product highlights at Stand 2253 at AHR Expo in Orlando from Jan.25-27.
“With more than 40 sites around the world offering a wide variety of compressor options for refrigeration and air conditioning applications, we’re always able to offer our users the right solution for any operating conditions,” says Peter Narreau, president of Bitzer North America.
CO2 technology – CKH reciprocating compressors
The Bitzer trade fair stand is worth a visit if you’re interested in innovative CO2 compressor technology, as the company is showcasing its CKH reciprocating compressors for transcritical CO2 applications. The four-cylinder model on display belongs to a compressor range with displacements between 1.9 and 22.3 CFM. All of the models in the series offer speed adjustment between 30 and 70 Hz and work with low pressure pulsation. The CO2 compressors are designed for standstill pressures of up to 1,450 psi low pressure and 2,320 psi high pressure.
“We’re confident that CO2 is one of the refrigerants of the future, as it offers key benefits, including a global warming potential of 1 that is practically climate-neutral and, at the same time, is exceptionally efficient, versatile and quiet. That’s why we developed and began manufacturing CO2 compressors over 15 years ago,” says Narreau.
Versatile reciprocating compressors – Ecoline CRII and Varispeed
Bitzer will be showcasing Ecoline reciprocating compressors with two distinct capacity control options in Orlando. The mechanical CRII capacity control supports a wide range of control between 10 and 100 percent. To develop the CRII, Bitzer optimized CR capacity control with blocked suction and introduced a hollow control piston. The CRII promotes a higher switching frequency.
The Ecoline Varispeed features a suction gas-cooled frequency inverter. It has a range of 25 – 87 Hz. The result is precise temperature control with the least power consumption.
With displacements between 3 and 157 CFM (60 Hz) and a variety of approved refrigerants such as R404A, R407A, R407C, R407F, R448A, R449A, R507A, R290 and R1270, Ecoline reciprocating compressors are suitable for a whole host of applications.
The combinable CSV and CSH screw compressors
BITZER’s three CSV screw compressors offer a unique benefit: optimized for use in air conditioning systems, heat pump applications and industrial and process cooling, the compressors are extremely efficient. We have integrated the liquid-chilled frequency inverter into the compressor, and it’s carefully fine-tuned at the factory and configured for maximum efficiency. The result is a very high IPLV value of more than 20 BTU/W. The CSV series is therefore unrivaled among air cooled liquid chillers with dry expansion.
Another benefit: the CSV series and CSH compact screw compressors can be combined in a single system, thus increasing versatility in full-load and part-load behavior. The semi-hermetic CSH compressors offer infinite or step-capacity control, are optimized for high condensing temp applications, and are the most efficient and quietest screws in their class,” says Narreau.
Team player – Orbit scroll compressors
Bitzer is also showcasing its Orbit 6 and 8 series R410A scroll compressors, which are designed for use in air conditioning systems and heat pumps. With displacements between 20 and 38 m3/h (706 and 1,342 ft3/h) for the Orbit 6 and between 17 and 45 CFM for the ORBIT 8, these scroll compressors offer a wide range of applications.
“By combining uneven scroll compressors in a circuit, the BAHT system makes it possible to achieve a wide variety of capacity staging combinations,” states Narreau, “and this represents a unique capability that only Bitzer can offer and a major benefit that throws open a whole array of new options when configuring future systems.”
