PET products 28 PET planet insider Vol. 11 No. 06/10 www.petpla.net PET chiller: Self adjustable and auto- adaptive to processing conditions Piovan has launched a new product to improve the energy efficiency of chilled water sys- tems. PET Chiller has been developed specifically for PET production lines and can be used in all processes requiring high refrigeration capacity, water flow and pressure. The company claims that its product is more efficient than conventional chillers as it is equipped with inverter-controlled compressors, meaning it can self-adjust its refrigeration capacity as necessary. It also uses brazed plate evapora- tors and compressors, which exchange the cooling power to the refrigerant and water more efficiently. Chillers are utilised at partial loads as are systematically sized with some spare capacity. With conventional chillers one can say that the lower the cooling load is in respect to the maximum refrigeration capacity the higher is the energy utilized to produce refrigeration kW. PET Chiller instead modulates its refrigeration capacity. Piovan says that the unit that can perform COP in excess of 8 (0.45kw) of energy per 1t of refrigeration power). The company has been replacing old chilled water refrigeration systems with PET Chiller since late 2009. The PET chiller is one of a number of new products it will be introducing to the American market this year. www.Piovan.com Light weighting across the closure range KTW Group has launched a range of standard clo- sures for beverages that bring light weighting advantages to all bottles, from 26 to 38mm. The company’s KTW 13 LT 26.7mm Alaska closure uses a shorter neck – 8.8mm com- pared with 14.5 mm – that saves PET and is 0.9g lighter. It offers opportunities for material savings for companies that have not yet invested in PC1881 systems. KTW has developed a new 29/25 line for the coming season, which has a shorter height and is also lighter. It also announced that its KTW 9 LT 30/25 series will change to 29/25 and that it is currently selling the system for testing. KTW also makes high-performance 1881 closures for CSD; users include Coca-Cola. It is also launching a new one-piece closure system that includes an internal seal. www.ktw-group.com Vinetta for mid-tier bottlers Krones AG devel- opped a compact labeller. The Krones Vinetta is available in sizes rated at 4,000 and 8,000 contain- ers per hour and has been designed spe- cifically for mid-tier bottlers. The stand- ard version of the machine, glass and plastic bottles, jars, and shaped contain- ers can be dressed in body and shoulder labels. An additional cold-glue sta- tion enables back, neck-ring or swing-stopper labels to be applied as well. The machine can also be fitted with a pressure-sensitive labelling station and has the option for the application of wine seals, diagonal stripes or medal- lions. The machine’s label magazine holds 5000 labels and has short make-ready times when changing over to different labels. It also has replaceable wear strips for the bottle handling parts. The company says that it will once again be offering bottlers of relatively small quantities at wineries, breweries and other sub-sectors of the bever- age industry labelling technology that is second to none. www.krones.com
