Air separators are used to continuously remove the air contained in the hydronic circuits of heating and cooling systems. The air discharge capacity of these devices is very high. They are capable of removing automatically all the air present in the system down to micro-bubble level. The circulation of fully de-aerated water enables the equipment to operate under optimum conditions, free from any noise, corrosion, localized overheating or mechanical damage. Micro-bubbles, fuse together, increase in volume until they become large enough to rise to the top where they are automatically released.

The Grundfos UP10-16B5/ATLC model is a Bronze Comfort Series Pump with Aquastat, Timer, Line Cord and has 1/2” sweat inlet/outlet connections. Replaces old 96433896 model. Grundfos Comfort series pumps, such as the UP10-16B5/ATLC model are most commonly used for domestic hot water recirculation applications, and can be also used for other small heating and recirculation projects.

Grundfos UP10-16B5/TLC model (Grundfos SKU# 96433895) is a Bronze Comfort Series Pump with Timer, Line Cord and has 1/2” sweat inlet/outlet connections. Grundfos Comfort series pumps, such as the UP10-16B5/TLC model are most commonly used for domestic hot water recirculation applications, and can be also used for other small heating and recirculation projects.

The i-Link series Zone Valve Controls simplify the field wiring and yet control up to six zone valves in a multi-zone hydronic heating system. The contractor friendly Printed Circuit Board eliminates the problem caused by incorrect wiring and saves hours of installation time. There would be no more “messy” look of conventional zone valve installations.

Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with Priority Protection Timer ensures other zones get heat every one hour and prevents freeze-ups in the event of a priority zone failure. The End Switch delay timer let the two wire type zone valves fully opened before turning on the circulator. The panel provides EZ screwless terminal blocks for connections to the thermostats and zone valves. In addition, LED indicators on the front panel provide functional status and easy troubleshooting.
