the salt content can be controlled to create salt free slurry or salt water slurry of any salt concentration ; and the size of the crystals in the slurry can be controlled . the most effective state of deepchill can then be pumped and discharged at different points in a facility for example very liquid with low ice concentration for rapid pre chilling slurry for continued chilling during processing long lasting paste with very high ice concentration for temporary or overnight storage and dry pure water crystals for packing . features edit the main features of deepchill variable state ice include slurry with an ice concentration of up to 70 % ice fraction can be transported through standard piping using conventional pumps . it has the highest heat transfer or cooling rate of any form of ice . it refrigerates evenly without freezing the product . the ice particles have no sharp edges to damage the product . the ice particles do not bridge or collect into clumps . ice temperature can be controlled and maintained for prolonged periods . applications edit chilling fish with thick slurry ice the following are current users of deepchill variable state ice slurry systems fishing boats seiners shrimp boats trawlers and longliners industrial ice vendors seafood processing plants high value seafood industries e.g. sashimi grade tuna growers and packers of fresh produce construction industries cooling buildings using thermal energy storage beverage cooling industries supermarket refrigeration and displays railway car cooling for the transport of perishable goods poultry processing plants see also edit slurry ice references edit world fishing & aquaculture new sunwell fresh water chiller . www.worldfishing.net . retrieved 2016 07 06 . external links edit sunwell technologies inc. website retrieved from https en.wikipedia.org w index.php title sunwell technologies & oldid 733739289 categories manufacturing companies of canadacompanies based in vaughanhidden categories articles lacking reliable references from may 2008all articles lacking reliable references navigation menu personal tools not logged intalkcontributionscreate accountlog in namespaces article talk variants views read edit view history more search navigation main pagecontentsfeatured contentcurrent eventsrandom articledonate to wikipediawikipedia store interaction helpabout wikipediacommunity portalrecent changescontact page tools what links hererelated changesupload filespecial pagespermanent linkpage informationwikidata itemcite this page print export create a bookdownload as pdfprintable version languages add links this page was last modified on 9 august 2016 at 20 18 . text is available under the creative commons attribution sharealike license ;
