BITZER, the specialist in refrigeration compressors, will be showcasing a compact, intelligent screw compressor from the CSV series at its trade fair stand. With an ESEER (ESEER: European seasonal energy efficiency ratio) value of over five, these all-rounders for heat pumps, building air conditioning and process cooling are setting new benchmarks in air-cooled liquid chillers with dry expansion. All the components are wired and tested at the factory and functional, and the frequency inverter is already integrated into the compressor, thus significantly reducing life cycle costs. The compact unit requires little space and fulfills the requirements of the EMC Directive for industrial and residential zones. Cooled by refrigerant, the electronics ensure maximum operations security and require minimum maintenance. Due to its high energy efficiency, the German specialist publication, Produktion, recently named the CSV series Product of the Week (issues 43 and 44, 2012).
The second compressor technology that trade fair stand visitors will want to see is the ORBIT 6 scroll compressor: with a delivery rate of between 20 and 38 m3/h (50 Hz), the five models of this scroll series boast high isentropic efficiency for a whole host of applications and a low sound level. ORBIT 6 compressors are therefore ideal for use particularly in air conditioning systems and heat pumps – and are the perfect complement to the larger scroll compressors of the ORBIT 8 series. Specially developed for use with R410A, the tried-and-tested ORBIT 8 series comprises six delivery rates ranging from 29 to 77 m3/h (50 Hz). With its ORBIT 8 series, BITZER is making a contribution to achieving an even higher level of efficacy and thus flexibly reacting to the energy efficiency requirements of the heating, ventilation and air-conditioning (HVAC) sector. Another major advantage of the ORBIT 8 series is the operating sound level, which is up to 3 dB(A) lower than competitors’ products. The extremely low oil circulation rate of less than one per cent contributes to improving the transfer of heat and increasing system efficiency and reliability.
BITZER will also be showcasing the entire NEW ECOLINE reciprocating compressor series. With a delivery rate of 4 to 221 m3/h, NEW ECOLINE compressors are used in normal- and low-temperature applications and heat pumps. BITZER will also be displaying a model from the NEW ECOLINE VARISPEED series, the speed of which can be infinitely adjusted thanks to an integrated frequency inverter, thus considerably reducing energy costs.
At the other half of the trade fair stand, Lodam will be presenting energy-saving control devices for air conditioning, heating and ventilation systems. Lodam heat pump controllers enable you to gain total control of hot water and heating for domestic comfort. They are energy and cost-efficient thanks to intelligent control provided by frequency inverters. Intelligent defrost scheduling saves energy and ensures low capacity waste. Also exhibited, the air handling unit controller by Lodam offers a vast number of innovative and energy-saving opportunities for demand-driven ventilation. The new heat pump and air handling unit controller range offers customers the opportunity to design their own menu and cabinet in line with their corporate identity. The main control functions of the user interface use fully tested, standard hardware and software components developed through years of experience to ensure reliable operations.
