Caleffi Series 257 iSolar BX Multi-functional Temperature Differential Controller
The iSolar™ BX is a multi-functional temperature differential controller with
add-on system functions for use in a wide variety of solar thermal heating
applications. iSolar™ BX is equipped with four relay outputs; three triac
pump speed control relays and one standard relay. These outputs include
two pulse width modulation (PWM) outputs that enable energy conservation
measures for high-effi ciency direct current (DC) pumps. The controller
is equipped with fi ve Pt1000 sensor inputs, two analog Grundfos sensor
inputs, and one impulse fl ow meter input. Twenty six system confi guration
options are predefi ned for control of a standard solar water heating system,
drainback systems, supplemental space heating, multiple storage tanks,
heat dump and storage tank booster heating.
Adjustable thermostatic and pressure
balanced mixing valve for point of
distribution in domestic water systems
and radiant hydronic heating systems.

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.
Grundfos Brute Three Speed Bronze Recirculator Pump
The Grundfos UPS26-99BFC (52722518) model incorporates a three speed motor for increased versatility, a built-in check valve and a bronze housing for ehnaced corrosion resistance. The wet rotor design allows it to be virtually silent while operating, while built-in motor protection assures long life of the circulator. Performance parameters (flow rates and pressure drop) of the Grundfos UPS26-99BFC model make it well suited for a wide range of applications, from radiant and hydronic heating, to domestic hot water recirculatio, solar, chilled water cooling and many others.
