IMI Hydronic supplier in Romania
Hydronic solutions for industrial installations
Founded in 1897 · Headquarters: Sweden (historical roots in Ljung)
Who is IMI Hydronic and what does it make?
IMI Hydronic Engineering is a group with Swedish roots dating from 1897, known for hydraulic balancing and flow control systems in HVAC installations, under the IMI TA, IMI Pneumatex and IMI Flow Design brands. The IMI TA range has included manual balancing valves since 1957 and today covers classic balancing valves (STAD, STAF, STAF-SG) and pressure-independent control valves (PICV) such as the TA-Modulator and TA-COMPACT-P. For the Romanian market, IMI Hydronic means access to key equipment for the proper balancing of heating and cooling installations.
What sets the range apart is the combination of manual balancing valves, with a DN 20-400 range and PN 16/PN 25 nominal pressures on the STAF/STAF-SG series, with pressure-independent valves from the PICV family, which automatically regulate the flow regardless of pressure variations in the network — a more advanced technology than classic manual balancing. The IMI Pneumatex brand completes the portfolio with pressurisation and degassing equipment (the Statico and Compresso Connect series), for complete control of the hydraulic circuit, not just the flow.
IMI Hydronic suits centralised heating/cooling installations, office buildings or large residential complexes, where correct hydraulic balancing between circuits reduces energy consumption and eliminates over- or under-supplied zones of heat-carrier fluid.
What do we supply from the IMI Hydronic range?
| Product | Description |
|---|---|
| STAD/STAF/STAF-SG Balancing Valves | A family of manual hydraulic balancing valves, with STAF and STAF-SG covering a DN 20-400 range at PN 16 and PN 25 nominal pressures, STAF being cast iron and STAF-SG ductile iron. STAD is the manual balancing valve of the range. Recommended for balancing heating/cooling circuits where the flow is set once, at commissioning. |
| TA-Modulator Pressure-Independent Valve | PICV (pressure independent control valve) that combines the balancing function with automatic flow control, regardless of pressure variations in the network. Recommended for installations with variable pressure, where a classic manual balancing valve would need rebalancing at every change in system load. |
| TA-COMPACT-P PIBCV Valve | Pressure-independent balancing and control valve (PIBCV), with adjustable maximum flow capacity and an overflow prevention function. Compatible with measuring instruments for advanced diagnosis of the circuit. |
| Statico and Compresso Connect Pressurisation Systems | IMI Pneumatex equipment for maintaining the correct pressure in the hydraulic circuit — Statico as an expansion vessel system, Compresso Connect as a connected pressurisation unit. They complete the balancing valves where system pressure must be actively controlled, not just the flow in each circuit. |

How do we supply IMI Hydronic in Romania?
We bring in IMI balancing and control valves (STAD, STAF, TA-Modulator, TA-COMPACT-P) through supply channels in the EU, to order. For this brand we work from the manufacturer's technical documentation — the documentation available is not a complete code catalogue, so each order is confirmed with the DN size, nominal pressure and exact type through our supply channels. On order, usually 1–4 weeks from order confirmation. For a correct quotation we need: the required DN size, the nominal pressure of the installation (PN 16 or PN 25), whether manual balancing or pressure-independent control (PICV) is needed and whether the installation also requires pressurisation components. Availability is confirmed in the quotation for every range.
We check complete order codes and the availability of variants with electric actuators for the TA range through our supply channels.
Frequently asked questions about IMI Hydronic
What does IMI Hydronic make?
IMI Hydronic makes hydraulic balancing valves and flow control for HVAC installations, under the IMI TA brand (STAD, STAF, TA-Modulator valves) and IMI Pneumatex (pressurisation, with systems such as Statico and Compresso Connect).
What is the difference between an IMI STAF valve and a TA-Modulator?
STAF is a manual balancing valve, set once at commissioning, while TA-Modulator is a PICV valve, which automatically regulates the flow regardless of later pressure variations in the installation.
What DN range does the IMI STAF range cover?
The STAF series and the ductile iron variant STAF-SG cover a DN 20-400 range, at PN 16 and PN 25 nominal pressures.
Can you supply IMI Hydronic valves in Romania, and in what time?
Yes, we bring in IMI valves to order through supply channels in the EU, usually in 1–4 weeks, depending on the size and type confirmed through our supply channels.
How do I request a IMI Hydronic quotation?
Send the IMI Hydronic code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
