UV Resistant Black Ploypropylene pipe for use with Venting Gas Appliances. Available in 2", 3", and 4" diameter.
PolyPro is a polypropylene vent pipe for use with ANSI Category II
and IV gas burning appliances, including tankless and storage water
heaters, high-efficiency water heaters, condensing boilers and warm
air furnaces. PolyPro is listed by Intertek to the ULC S636 standard in
Canada and is rated as a Class IIA, IIB and IIC vent system suitable for
exhaust temperatures up to 230°F / 110°C, and a maximum positive
pressure of 15 in-w.c.

Caleffi Series 257 iSolar Multi-functional Temperature Differential Controller
The iSolar™ 257 series are multi—functional temperature differential controllers
that provide complete control of the solar thermal system for safe
and long—lasting operation. The microprocessor based controller monitors
and controls thermal solar systems by means of a collector sensor and a
storage tank sensor. The controllers also perform important system monitoring
and safety functions. The system parameters and measured values can
be changed and viewed on the large LCD display. The controller is equipped
for up to four temperature sensor inputs and one or two 120 VAC outputs
(some models) for activating the solar circuit pump and second 120 VAC
output for activating a valve or second pump. The controller is additionally
equipped with VBus® for two-way communication between modules, PC’s
or data loggers.
Z-one valves are used to automatically shut-off the flow or redirect hot and
chilled water in hydronic heating and air conditioning systems. The motorized two position, on/off/, spring return A1 series actuator has an
end mounted push button for quick installation to valve body. The actuator is
equipped with or without auxiliary switch and configured Normally closed or
Normally Opened with wire or terminal connections.
Universal Flow Switch for heating systems. 1" NPTM, Brass body, Suitable for 1" to 8" pipe. UL listed.
Universal Flow Switch for heating and air conditioning systems. Suitable for 1" to 8" pipe size. Working pressure: 150 psi. Working Temperature: 250 F. Minimum Flow: 5.7 GPM. Rating of switch contacts : 5A. CE, cUL, NEMA Type 5, IP 54
Air separator.
Brass body.
Glass reinforced nylon internal element.
½" NPT female bottom thread.
Max. working pressure: 150 psi.
Working temperature range: 32—250°F.
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.
