Hysopt x IMI: smart collaboration for precise hydraulic design

We’re proud to announce a new partnership with IMI, bringing their balancing and control valves into Hysopt’s software. This integration enables HVAC engineers to design smarter and faster with automated valve selection, real-time optimisation, and accurate system performance from the start.

We’re proud to announce a new step in our mission towards more transparent HVAC design. In collaboration with IMI, a selection of their (dynamic) balancing and control valves will soon be available in the Hysopt software.

This integration follows requests from several Dutch customers who frequently work with IMI components in their projects. By integrating IMI product data directly into the design environment, we’re enabling engineers to work faster and more accurately — from first concept to implementation-ready design.

From manual calculation to automated optimisation

We’re starting with the integration of some of IMI’s most widely used valves: STAD/STAF, TA Modulator, TA Smart, and TA Nano.

STAD and STAF are static balancing valves designed to ensure the correct flow rate in every circuit of an HVAC system. Traditionally, calculating the correct pre-set (valve setting) is a manual task, based on the required flow and the valve’s characteristics — a time-consuming and error-prone process, especially when system changes occur later on.

Thanks to this integration, that calculation will now be handled automatically by Hysopt. Our software not only selects the right valve for each position in the system, but also continuously calculates the optimal pre-set in real time, even when design changes are made. This significantly improves accuracy and reduces design time.

Designing smarter and faster with dynamic control valves

In addition to the static valves, we’re also integrating dynamic solutions like the TA Modulator and TA Smart. These pressure-independent control valves ensure stable and modulating flow regulation, even when system pressures fluctuate.

With direct access to product specifications and control characteristics, engineers can now select these components correctly from the start. This not only speeds up the design process but also helps avoid mistakes and oversizing.

The TA Nano is a compact pressure-independent valve specifically designed for small zones, such as fan coil units or compact heat pumps. Its small size and integrated control make it ideal for applications with limited space, without compromising performance.

By integrating all of these valves into the Hysopt software, engineers can make informed design decisions from the very beginning — with real data that reflects how systems actually behave. This leads to more efficient and consistent designs, both for large systems and small-scale applications.

A shared ambition

This collaboration between Hysopt and IMI reflects a shared ambition: to design and deliver HVAC systems that don’t just work on paper, but perform as intended in real-life operation. By joining forces, we make it easier for engineers to make data-driven decisions and save valuable time in both the design and implementation phases.

We look forward to making this functionality available to all our users soon.
