Wilo Classic Star S 21FX 3 Speed Cast Iron Circulator, Rotated 90 Flange
Wet rotor circulation pump, with flanged connection. (Flange parallel to shaft). Pre-selectable speeds to adjust the capacity on "S" versions. Cast iron body for hot-water heating systems of all kinds, industrial circulation systems, cold-water systems and air-conditioning systems.
Swedged Manifolds are Easy to Stock and Easy to Assemble. There is Sufficient Copper on the Closed End to Cut off and Sweat to Another Manifold. Solder a 2-Branch to a 3 Branch to Make a 5 Branch, a 3-Branch and a Four Branch to make a 7 Branch etc. Four Fitting Styles are Available: Onix, PEX Crimp, RadiantPEX-AL Press, and RadiantPEX-AL Compression. Swedged Manifolds are Sold Individually, with or without Mini Ball Valves (MBVs).
Johnson Controls Single Stage Digital Temperature Control (120/240v SPDT)
The A419 series controls are single-stage, electronic temperature controls with a Single-Pole, Double-Throw (SPDT) output relay. They feature a lockable front-panel touchpad for setup and adjustment, and a Liquid Crystal Display (LCD) for viewing the temperature and status of other functions. A Light-Emitting Diode (LED) indicates the controls? output relay On/Off status. The A419 controls are available in 24 VAC or 120/240 VAC powered models. The A419 controls have heating and cooling modes, adjustable setpoint and differential, an adjustable anti-short cycle delay, and a temperature offset function. The setpoint range is -30 to 212°F (-34 to 100°C). The controls feature remote sensing capability and interchangeable sensors. The A419 controls are available in either NEMA 1, high-impact plastic enclosure suitable for surface or DIN rail mounting or NEMA 4X watertight, corrosion-resistant surface-mount enclosures.
Dirt Separator.
Brass Body.
1/2" NPT Top Thread With Plug For Optional Air Vent, Code 502243A
Max. Working Pressure: 150 PSI.
Working Temperature Range: 32-250F.
Particle Separation Capacity: To 0.2 mil
In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.
Automatic air vent with service check valve.
