Web site information addresses are supplied throughout this manual for piping and accessory information.
The plumbing industry also has pressure drop information on ferrous and copper piping systems.
The following sections will describe each component and how it functions within the system. Installation
information is supplied where appropriate. The piping design section will explain the design and layout
the piping system from a “how to” perspective. Following the examples provided will enable the installer
to determine the correct pipe and accessory sizing, as well as equipment location. It is important to know
before installation if the proposed system will operate correctly and by doing a formal layout of a new
application or review of an existing piping system will make that determination.
Throughout this manual the term “liquid solution” is used in place of water. The chiller circulates a
solution of water and Propylene Glycol.
It is essential to operate the system with a minimum of 10% glycol. DO NOT OPERATE THIS
SYSTEM USING WATER ALONE.
For proper liquid solutions mix ratios, refer to page 14 or the glycol manufacture’s recommended mix
ratios.
