  3. 1"  Caleffi 663 Series Distribution Manifold

    1" Caleffi 663 Series Distribution Manifold

    1" NPT Inlet Ball valves and 3/4" outlets. This pre-assembled distribution assembly with Return distribution manifold including Built-In Shut-Off Valves suitable for Thermo-Electric Actuators, and Supply distirbution manifold including Manually-Adjustable Balancing Valves. MAX working pressure: 150 psi. MAX temperature 210 F.
    Distribution manifolds for radiant panel systems are used to optimally distribute the heating fluid in floor heating system circuits and ultimately improve the control of heat emission from the panels. The manifolds ensure that the flow of each circuit is regulated precisely and also control the shut-off, venting and automatic removal of air from the system.

  4. Steca TR 0502 Solar Thermal Controller

    Steca TR 0502 Solar Thermal Controller

    Steca TR 0502 Solar Thermal Controller

    The new Steca TR 0502 solar thermal controller closes the gap between the already successful Steca TR 0301, TR 0301sc and TR 0603 temperature difference controllers.

    With its animated graphic display and elegant design, it continues the success enjoyed by this family of controllers. This controller provides everything to operate your solar thermal system safely over a long service life. The Steca TR 0502 controller monitors and controls solar thermal systems with up to two differently oriented collector arrays and a maximum of two domestic hot water or buffer storage tanks. The large graphic display shows the animated control circuits, which allows you to view the operating statuses of each system. The clearly arranged display ensures easy operation using pictograms. Pre-programmed systems enable universal usage. The Steca TR 0502 controller has five inputs for recording temperatures or pulse values, as well as two outputs (one is speed-controlled) for controlling pumps or switching valves.

  5. Fernox Express Boiler Comissioning Kit

    Fernox Express Boiler Comissioning Kit

    Fernox Express Boiler Comissioning Kit

    Good practice dictates that hydronic central heating systems should be thoroughly cleaned and flushed before installing a new boiler, after which a chemical inhibitor should be added to ensure the system is protected from corrosion, scale and sludge build-up. These procedures should also be employed when major work is carried out on a system. A clean, protected system helps ensure that the heat generated by the boiler is transmitted efficiently into the house over the long term

    • Maintain the design specification and energy efficiency
    • Restore energy efficiency
    • Inhibit the formation of scale and sludge
    • Minimize corrosion of system metals
    • Product code: 59480

     

    Contents:

    • 1 x Fernox Protector F1 17.6oz (500ml)
    • 1 x Fernox Cleaner F3 17.6oz (500ml)
    • 4 x Fernox pH Test Strips

  8. Caleffi Discal Series 551 Air Separators Brass Sweat

    Caleffi Discal Series 551 Air Separators Brass Sweat

    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.
