BITZER compressors are indispensable in many branches of industry. BITZER products are renowned for their efficiency, operating reliability and low life cycle costs in numerous industrial refrigeration applications. For example, refrigeration compressors from BITZER are used in low-temperature storage at chain stores, help to flash-freeze foods and make it possible to manufacture and store essential medication.
BITZER compressors in the field of commercial refrigeration allow for fresh produce all year round, regardless of the temperature outside. Only when cooling chains function with absolute reliability do the quality and shelf life of food not decline. BITZER products help to ensure that temperature-sensitive goods reach the end customer with the highest possible level of quality.
The compact semi-hermetic reciprocating compressors are suitable for a whole host of refrigerants. Our compressors boast an efficient suction gas–cooled motor, high-quality valve plates, wear-resistant drive gears and adjustable capacity control.
SEMI-HERMETIC WITH INNOVATIVE MOTOR TECHNOLOGY
The ECOLINE+ reciprocating compressors represent the next level of energy-efficient BITZER compressors. By using CO2 as a refrigerant in combination with LSPM motor technology and, optionally, with intelligent electronics, ECOLINE+ compressors enable the highest energy efficiency possible.
The semi-hermetic reciprocating compressors, which compress the refrigerant in two stages, are optimized for the low-temperature refrigeration range. Liquid subcooling significantly increases the cooling capacity and efficiency of the entire system.
With the built-in pre-programmed frequency inverter of the VARISPEED series, the speed can be infinitely adjusted, which increases efficiency and lowers energy costs. The built-in suction gas cooling of the frequency inverter increases operating reliability and reduces maintenance to visual inspections only.
Open-drive reciprocating compressors are available in two model series: for (H)CFC/HFC refrigerants and for ammonia. Due to the open-drive construction, standard motors can be attached to the compressor via coupling housing or belt drive. Reliability and easy maintenance have made them popular options for years.
The open-drive two-stage reciprocating compressors are specially optimized for the low-temperature refrigeration range. The optional liquid subcooler can significantly increase the cooling capacity and efficiency of the entire system. Standard motors can be attached to the compressors via coupling housing or belt drive.
Designed for use in commercial and industrial applications, the semi-hermetic screw compressors are suitable for (H)CFC/HFC refrigerants and offer efficient mechanical capacity control. The concept of a parallel circuit with the same and different models offers high levels of reliability and versatility.
Open-drive screw compressors are available for (H)CFC/HFC refrigerants and for ammonia. With their high cooling capacity, they’re suitable for industrial applications and marine refrigeration systems. They can be operated with commercially available standard motors attached via standard couplings and coupling housings. A special model is available for use in explosion protection zones.
The speed-regulated semi-hermetic compact screw compressors for use in industrial liquid chillers and heat pumps are true innovations. Thanks to the refrigerant-cooled frequency inverter, they achieve maximum efficiency particularly in part-load and thus the best ESEER/IPLV and SCOP figures.
Equipped with mechanical capacity control and an extensive application limits diagram, the semi-hermetic compact screw compressors are suitable for use in industrial liquid chillers and heat pumps. The built-in oil-separating system facilitates simple system construction and fast installation.
Optimized for air conditioning technology in vehicles: the hermetic compact screw compressors are designed for use in railway carriages and coaches. With their thin design, low weight and smooth running, they’re ideal for installation in confined roof and under-floor spaces.
