Caleffi International NV - Brochure Solar

COMPONENTSFOR SOLAR THERMAL SYSTEMS

2011

The Caleffi Solar product range has been specially developed for use in solarthermal systems, where high temperatures can normally be reached and where,depending on the kind of system, there can be glycol. Materials and performanceof the components must necessarily take into account these particular operatingconditions.

SOLARNOCAL

Function

A thermostatic anti-scald mixing valve, at the kit inlet, controls thetemperature of the water coming from the solar hot water storage.The thermostat, by means of the probe positioned on the hot waterflow from the solar hot water storage, controls the diverter valve atthe kit outlet. Depending on the temperature setting, the valvediverts the water towards the user circuit or activates the boilercircuit, without thermal integration.

Solar storage-boiler connection kit, without thermal integration.Consisting of:- thermostatic anti-scald mixing valve, adjustable with knob, for solar thermal systems. Complete with strainers and check valves at the inlets;

- diverter valve with three-contact actuator, with auxiliary microswitch;- thermostat with probe for solar thermal system, for operating diverter valve. Display showing temperature.

Depending on the temperature setting, the valve divertsthe water towards the user circuit or the boiler circuit, with thermalintegration.A thermostatic anti-scald mixing valve, at the kit outlet, constantlycontrols the temperature of the water sent to the user.a aa a aa aaaApplication diagram of SOLARINCAL kit 265 series

SOLARINCAL-T

Function

A thermostatic diverter valve, at the kit inlet, receives hot watercoming from the solar water storage.Depending on the temperature setting, the valve diverts the waterautomatically and in a proportional manner towards the user circuitor the boiler with storage circuit, with thermal integration.The valve modulates the flow rates to optimise the energycontained in the solar storage and reduce boiler operation times toa minimum.A thermostatic anti-scald mixing valve, at the kit outlet, constantlycontrols and limits the temperature of the water sent to the user.

SOLARINCAL-T PPLLUUSS

Function

A thermostatic diverter valve, at the kit inlet, receives hot watercoming from the solar water storage. Depending on thetemperature setting, the valve diverts the water automatically andproportionally towards the user circuit or the instantaneous boilercircuit, with thermal integration. The valve modulates the flowrates to optimise the energy contained in the solar storage andreduce boiler operation times to a minimum. A specific thermostatic control device limits the boiler inlettemperature to prevent it being switched on and off too often, whichleads to hunting and irregular operation. A thermostatic anti-scald mixing valve, at the kit outlet, constantlycontrols the temperature of the water sent to the user.
