Their modular design enables plastics pro- cessors to start with just one chiller and expand to a plant- wide multiple chiller system, operated by a single controller, the company says. ESE chillers are available with integrated pumps and fluid reservoir or as a standalone chiller to supply a sepa- rate pump tank system. Systems can be water cooled, using tower water, or can be installed in a remote-air-cooled condenser configuration. The range extends to 12 different sizes, from 10 to 160t. Single refrigeration circuits are avail- able on units from 10 to 80t capacity, with dual refrigeration circuits on 20 to 160t machines. Each refrigeration circuit has two Copeland scroll compressors, which is designed to enable the system to stay up and running even if one of the compressors has to be shut down for maintenance. Users can install one or more ESE chillers and then add more modules up to a total of six for cooling capacity to 960t. Up to 12 refrigeration circuits can be connected to a single control interface using twisted-pair wiring, allowing central- ised control. The standard Panasonic PLC control operates with proprietary programming developed specifically for the ESE chillers. The LCD touch-screen user interface is designed to facilitate quick monitoring and control, using a clear, simple- to-understand display. All circuits are controlled using readings from a common manifold-mounted temperature sensor. Conair says that this helps to avoid blending and temperature drift that can occur when individual supply and return sensors are used. Elec- tronic expansion valves compensate automatically for load variations and ambient conditions. The condenser-water regulating valve is also electronic. Extensive temperature and pressure displays, trending screens and efficient diagnostic tools are intended to make commissioning and fine-tuning easy. Conair claims that service and maintenance personnel typically do not need separate meters or gauges. ESE chillers, which are built in an ISO 9001:2008-certi- fied facility, use standard direct-drive scroll compressors. Conair claims that these are inherently more reliable than most other designs and are hermetically sealed in order to minimise maintenance requirements. Remote air-cooled models have corrosion-resistant brazed-plate, stainless-steel evaporators. Water-cooled units feature a shell-and-tube condenser and a filtration system to keep out debris and prevent clogs. Chillers with integral stainless-steel reservoir and pumping system are delivered piped, wired and ready for installation. www.conairgroup.com RPC creates narrower jar for Tangerine Confectionery RPC Containers Ltd, which is based in Blackburn, England, has created a new, narrower jar for Tangerine Confectionery Ltd, an independent UK manufacturer of sugar confectionery and branded popcorn, based in Pon- tefract, England. RPC was asked to create the new pack as a result of its long-term supplier relationship with Tangerine Con- fectionery.The 3.6l injection-moulded PET jar, made in a custom mould, is the same height as a 4l version. RPC asserts that this means that it maintains the same on- shelf presence. Tangerine has switched its Taveners “traditional sweet shop range” and Jameson’s high-quality choc- olate-covered confectionery to the new, classic-style container, which has been specifically developed for Tangerine’s cash and carry customers. Its glass-clear appearance is designed to highlight the colourful prod- uct within. The wide neck, which is designed for easy dispensing, uses a 105mm black cap supplied by RPC Halstead. www.rpc-blackburn.co.uk www.tangerineuk.net
