Pro-Tek 922 Concentrated Corrosion Inhibitor

Pro-Tek® 922 is a concentrated corrosion inhibitor treatment specially formulated for hot water closed loop heating systems.

Pro-Tek® 922 is a concentrated corrosion inhibitor treatment specially formulated for hot water closed loop heating systems. Many water sources used in hydronic heating systems can be very corrosive to metals when heated. Pro-Tek 922 will help to reduce corrosion on aluminum, brass, copper, iron, and stainless steel. Pro-Tek 922 has also been tested and is compatible with standard PEX and Onix tubing typically used in hydronic installations.

Caleffi Discal Series 551 Compact Air Separator 3/4" Sweat

Air separator. Brass body. Stainless steel mesh internal element. ½" NPT bottom thread. Max. working pressure: 150 psi. Working temperature range: 32—250°F.

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.

Tjernlund DC6 Single Action Draft Control

Single Acting Galvanized Draft Control For Oil, Solid Fuel and Fan Assisted Gas Burners

Heating appliances are designed to operate with a consistent draft. Chimney configurations, mechanical draft fans and weather can cause draft fluctuations. These fluctuations result in inefficient combustion and more frequent service calls. Draft controls regulate the airflow through a chimney or vent. By diluting the chimney/vent draft with varying amounts of room air they maintain the draft at a heater's flue outlet within a consistent, safe and efficient range. This single acting control is made of galvanized steel for low maintenance and corrosion resistance. It has integral anchor points and self- aligning, self-centering rocker bearings for long lasting service. A cushioned stop minimizes rattle and noise. Adjustment is easily accomplished by moving counter weight on outside tab.
