Zilmet Hydraulic Separator for Hydronic Heating Systems

The Zilmet hydraulic separator (also called a low-loss header) is an insulated, multifunction unit for hydronic heating and chilled water systems. It hydraulically separates the primary boiler or chiller loop from the secondary distribution circuits, so each loop can run at its own flow rate without interfering with the other. Every unit also works as an air and dirt separator.

Key Features:

• Low-loss design handles flow rates up to 40 gpm, for residential and light-commercial applications
• Welded steel construction with welded baffles and no plastic internal components
• Perforated internal baffles for air and dirt separation
• Dual front accessory ports for temperature sensors and magnetic inserts
• High-capacity automatic float vent included
• Bottom port for a drain or blowdown valve
• Two-piece insulation with a hook-and-loop clamshell closure
• NPTF threaded system connections
• Rated to 150 psig and 200°F
• Compatible with water or glycol mixes up to 50%
• 5-year limited manufacturer warranty
