K SERIES WITH ECOLINE COMPRESSORS

An optimally coordinated range of condensing units with the efficient and robust BITZER compressors and high efficiency shell and tube condensers from the K-3 series.

LHE SERIES WITH 2ND GENERATION 2-STAGE COMPRESSORS

With the implementation of the Ecodesign Directive, fans will be subject to stricter efficiency requirements from 2015, and condensing units from 2016. The new air cooled LHE condensing units from BITZER meet these criteria and boast an optimized combination of fans and condenser. They’re taking the place of the previous models with the same connection sizes, making replacement simple. As a modular system, they’re available in several configuration levels and with single and tandem compressors.

L SERIES WITH 0-VII COMPRESSORS

Coordinated combinations of the proven open 2-cylinder compressors with air cooled condensers and collectors.

K SERIES WITH 0-VII COMPRESSORS

Open condensing units water cooled for belt drive

OSK = Application for air-conditioning and medium temperature cooling

Over a period of many years, BITZER’s open screw compressors have established a reputation as a robust and efficient market solution. They’re used on their own and in parallel operation with several compressors and a shared oil separator. The combination of open compressor and external standard motors makes the entire series exceptionally flexible and facilitates operation at different supply voltages. With the corresponding accessories such as couplings and coupling housing, BITZER ensures a simple and secure connection between compressor and external standard motor. Another advantage is that the refrigerant circuit and electrical drive are separate, which simplifies maintenance and repair, promoting utilisation in many special applications in particular, including in the chemistry and pharmaceutical industries, and resulting in the use of OS screw compressors on ships.

OSKB compressors are primarily used at the low-temperature stage of booster refrigeration systems. Thanks to their unique design, they’ve gained a great deal of trust among large-scale commercial and industrial users. In conjunction with OSK compressors for the high-temperature stage, a single refrigeration system can, for instance, accommodate low and medium temperature applications – for a simple, compact and cost-efficient solution.

The new air cooled LHE condensing units from BITZER meet these criteria and boast an optimized combination of fans and condenser.

The new CSH series is based on the proven design elements of the innovative BITZER compact screws, which are recognized as a benchmark around the world. They were developed with respect to universal application in air cooled liquid chillers and heat pumps. Besides their known attributes, the compressors are distinguished by further improvements to energy efficiency under full- and part-load conditions. Additionally, the application limits were greatly expanded both in terms of low saturation discharge temperatures and high pressure ratios (heat pumps) – without compromising operating reliability.

The compact screws of the new CSW series are optimised for use in R134a liquid chillers operating under low saturation discharge temperatures. As a result, they are compatible with systems with water cooled condensers, process cooling and systems with air cooled condensers operating under moderate climatic conditions. Thanks to their targeted development for these applications, their efficiency under full-load – and especially under part-load – was significantly increased. Additionally, the application limits under low saturation discharge temperatures were greatly expanded. Therefore, this series of compressors boasts ESEER/IPLV* values which greatly surpass the conventional international standards for compact screw compressors.
