Caleffi supplier in Romania
Components for heating and plumbing installations
Founded in 1961 · Headquarters: Fontaneto d'Agogna (Novara), Italy
Who is Caleffi and what does it make?
Caleffi is an Italian manufacturer of components for hydronic installations, based in Fontaneto d'Agogna, in the province of Novara, founded in 1961. The range includes hydraulic separators, air separators and dirt separators, thermostatic radiator valves, balancing valves and pressure reducing valves, mixing and distribution modules, and fittings. For the Romanian market we can quote components for heating, cooling and domestic water installations in residential and commercial buildings.
Caleffi makes 13 distinct categories of hydronic components, from the air and dirt separators used to protect boilers and circulation pumps, to the dynamic balancing valves of the FlowCal range, which keep the flow constant regardless of pressure variations in the network. Caleffi covers the regulation, protection and distribution of the heat-transfer fluid in the installation.
For installers and designers of thermal installations in Romania, Caleffi remains a resource for fine regulation components — separators, balancing valves, mixing modules — especially in buildings with heating systems on several circuits.
What do we supply from the Caleffi range?
| Product | Description |
|---|---|
| Hydraulic and dirt separators | Components mounted on the heating or cooling circuit to separate air and dirt from the heat-transfer fluid, thus protecting the boiler, circulation pumps and valves in the installation. They are used mainly in installations with several circuits, where the hydraulic mixing between circuits has to be controlled. The customer must state the design flow of the installation. |
| FlowCal dynamic balancing valves | Valves that automatically keep the set flow on a heating or cooling circuit, regardless of pressure variations caused by other circuits in the installation. Useful in installations with several zones or floors, where manual balancing would be hard to maintain. Selection depends on the design flow of each circuit. |
| Thermostatic radiator valves | Valves that automatically regulate the room temperature by controlling the flow of heat-transfer fluid to the radiator, used in residential and commercial heating installations with room-by-room control. |
| Distribution and mixing modules | Manifolds and mixing units for installations with several circuits at different temperatures, for example underfloor heating combined with radiators, where each circuit needs its own flow temperature. |

How do we supply Caleffi in Romania?
We bring in Caleffi components to order through supply channels in the European Union; we confirm availability in the quotation — we work with what the manufacturer's catalogue confirms. To order, usually 1–4 weeks, depending on availability at the suppliers in the EU. For a correct quotation we need the type of installation, the diameter of the connections and the design flow of the circuit concerned. Availability is confirmed on the code in the quotation for each product code in the 13 categories of the range.
For the Caleffi range we supply individual components, and the availability of each valve variant is checked on request; the design of the installation is carried out outside our quotation.
Frequently asked questions about Caleffi
Which Caleffi separator do I choose for decoupling the circuits of a boiler plant?
SEP4 is a 4-in-1 separator, which combines hydraulic separation with air, dirt and magnetic separation. For simpler installations, a standard Hydro Separator may be enough.
What is the difference between Caleffi FlowCal and QuickSetter valves?
FlowCal is a dynamic balancing valve, which keeps a constant flow regardless of pressure variations in the network. QuickSetter is a static balancing valve, where the flow is set manually once, at commissioning of the installation.
Do you supply Caleffi valves and separators in Romania?
Yes, we bring in Caleffi products to order, based on the manufacturer's product documentation; we confirm availability in the quotation. The lead time to order is usually 1–4 weeks, depending on the model and the diameter required. We recommend confirming the exact code before ordering.
What information do I send for a Caleffi hydraulic separator quotation?
It is useful to specify the total flow of the installation, the diameter of the connections and the flange type needed (union or ANSI). These details allow the correct choice between the SEP4, Hydro Separator or HydroCal series in the Caleffi range.
What is the Caleffi ThermoSetter valve?
It is a thermal balancing valve, used for regulating the temperature in domestic hot water recirculation systems (a modulating balancing valve).
How do I request a Caleffi quotation?
Send the Caleffi code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
