Bitzer the world’s largest independent manufacturer of refrigeration compressors will be proudly showcasing key innovations and products at FRIGAIR 2015, Africa’s only dedicated HVAC&R Expo held in Johannesburg on the 3rd – 5th of June.
Visitors can look forward to a host of HVAC&R innovations. (Look out for BITZER in Hall 5, stand A33)
Some of the BITZER products you can expect to see are:
ECOLINE Compressor with new CRII capacity control
The company will be showcasing their optimized CRII capacity control system, whichachieves an exceptionally wide range of control between 10 and 100% for four- and six-cylinder compressors. The system delivers virtually infinitely adjustable capacity control.
With the CRII system, BITZER is offering their customers a whole new level of flexibility and customization to suit all possible ECOLINE compressor operating conditions.
The BITZER ECOLINE range includes the VARISPEED series that comes with an integrated frequency inverter (FI) which allows stepless capacity control and has four unique attributes make this series very special: i) The frequency inverter is solidly flanged to the compressors motor cover ii) The suction gas cooling for the power elements of the FI ensure the optimum temperature of the electrical components and therefore no fan or regular maintenance work is needed iii) The compressor cooling capacity can be increased by up to 70% compared to a fixed speed of 50Hz iv) wide speed range from 30 Hz up to 87 Hz.
Bitzer BEST Software
One set of Software for all Bitzer Products. The BITZER ELECTRONICS SERVICE TOOL (BEST) is free Windows-based software that can access any BITZER electronic product. The tool has received an exciting design makeover, with a host of improved functions and more BITZER products added. With the BEST service tool, BITZER makes it simple to parameterize and analyze VARISPEED and CSV devices, and it now also supports the SE-i1 protection and monitoring device for screw compressors.
Trade fair visitors can see an air cooled BITZER ECOSTAR condensing unit, which adapts the cooling capacity to best suit actual requirements using the speed control of the compressor and fan.  Precise temperature control increases the efficiency of the refrigeration system and reduces operating costs, while the sound-optimised airflow ensures a low noise level.
BITZER’s will also highlight the ORBIT 6 and 8 scroll compressors, with their high isentropic efficiency and their excellent energy efficiency. The five models in the ORBIT 6 series offer a delivery rate of between 20 and 38 m3/h (50 Hz), and really impress with their wide range of applications as well as with their low noise levels. With a cooling capacity of between 27 and 51 kW at 50 Hz, they are especially suitable for air conditioning systems and heat pumps. Just like the ORBIT 6 scroll compressors, the ORBIT 8 series has been designed for the R410A refrigerant. The six ORBIT 8 compressors have a delivery rate of between 29 and 77 m3/h (50 Hz), achieve high efficiency rates and their operating noise levels are up to 3 dB(A) lower than comparable compressors

Keeping ahead of the information curve is critical in the HVAC&R sector where new technological innovations and advances happen continuously. BITZER plans to use FRIGAIR 2015 to share important HVAC&R innovations and developments.
