The Amcor HT-2000 Tower HEPA Air Purifier is the perfect way to refresh the air in your home. It removes 99.97-percent of irritating particles in the air and offers two-speed quiet operation, making it great for almost any room.

The handbook includes all the necessary information for the correct selection and successful application of the Alfa Laval ranges of Centrifugal, Liquid Ring and Rotary Lobe Pumps. One of the most important applications is refrigeration system, the topic of this manual. This is the fourth edition of the manual. Since the first edition, there has been an intense debate about refrigerants, both new, with and without glide and natural, such as pro-pane and ammonia. This debate has influenced the devel-opment of equipment including plate heat exchangers.

One of the effects on PHE's has been that the old boundary between the small BPHE for halogenated hydrocarbons in direct expansion systems and the large semiwelded PHE for ammonia in flooded systems has disappeared. Ammonia is increasingly used in direct expansion systems in nickel brazed PHE's and there are large brazed PHE's suitable for flooded systems. The decanter centrifuge has become a major processing tool in a wide range of liquid/solid separation applications. This handbook aims to be a thorough introduction to the design, performance and application of the decanter. It aims also to be a useful guide for the centrifuge engineer, both in equipment manufacturing companies and in the end-user companies, and their associated contractors and consultancies. The handbook's first chapter introduces the reader to the decanter, to its history and to the manufacturing sector within which it is made. The contents of this chapter are intentionally brief, with major expansion of the topics covered in later chapters of the book.
