COMPLETE WATER TEMPERATURE CONTROL SYSTEM

Transcription

1 OMPLETE WATE TEMPEATUE ONTOL SYSTEM MEGATON omplete Water Temperature ontrol Systems regulate water temperature for building hot water systems and other commercial, institutional and industrial applications. Thermostatic water mixing valves, DUA-trol solid bi-metal thermostatic control Adjustable high temperature limit stops set for Mixed water capacity from.5-8 (.9 - l/min) Simple installation, reduced setup costs All bronze, brass and stainless steel construction System mounted on strut with return piping and circulator Factory pre-assembled and tested as a complete control station Toll free technical support Valve Assemblies are ASSE Standard 7 and cup Listed

2 omplete Water Temperature ontrol System All MEGATON omplete Water Temperature ontrol Systems are supplied as factory assembled and tested with all inlet, outlet and return piping and include: High Low Manifold System with large and small Type TM Water Mixing Valves to meet high and low demands for mixed water Integral return piping including circulator, aquastat, check valves, bypass piping, and balancing valve to eliminate the possibility of piping installation error Outlet test connection arrangement, ball valve shutoffs on each mixing valve outlet and on hot and cold supplies for ease of installation and set up Dial thermometers on hot, cold, mixed and return piping lines for complete system monitoring Pressure gauge on tempered water piping Station mounted on galvanized strut for simple installation NOTE: The MEGATON model must be selected based upon the following: Maximum demand for mixed water System pressure drop Designer s estimated minimum water flow requirement Do NOT specify a MEGATON system for an installation where mixed water flow requirements are greater or less than the limits shown below.
