“With our current product range we are in a very good position to address precisely the demand in these product areas, and could therefore pick up numerous new contacts in these areas at the MCE,” reported the sales manager responsible for the domain of stationary application, Thomas Hagenlocher. With its Plug & Play solution for the demand-related speed control of refrigeration compressors using frequency converters, namely the EFC system, Bock offers an option for energy saving that is equally efficient and easy. The targeted use of refrigerant compressors featuring this EFC system creates a definite saving potential of 25% or even more, depending on the operating conditions. Lately this principle has been proving itself in thousands of refrigeration plants world-wide.

Of course, as Thomas Hagenlocher admits, the price for such an EFC system is considerably higher than that of a mechanical capacity regulator, as a result of the frequency converter being mounted directly onto the motor. ROI calculations however prove that this higher initial investment is redeemed after two years at most – a short period in view of the average total operating life of more than ten years for refrigeration plants. “Anyone who has bought this system from us and installed it for the first time, comes back as a regular customer,” affirms Hagenlocher time and again. As one of the pioneers in the field, the company has already been accumulating experience since the early 1990s, and now supplies notable OEM customers with semi-hermetic CO2 compressors for supermarket refrigeration. According to the company’s press release, besides these compressors for the use of CO2 as a refrigerant, models for the use of hydrocarbons like propane or ammonia complete the Bock product portfolio for the MCE 2008.
