The integrated system of smart valves and cloud-based software to manage climate control, save energy and cut bills.

A complete, innovative and sustainable solution

KnolvalTM is a system for energy optimisation in any hydronic circuit, thus for a better climate control. It includes the two-way control valves produced by Cimberio S.p.A. with flow and temperature measurement and a cloud-based software for:

In all these rooms with KnolvalTM you can:

  • Account for heat and cooling energy.
  • Make the most of existing installations (retrofit).
  • Improve room conditions and people’s comfort.
  • Reduce emissions and consumption.
  • Identify unknown waste and ‘invisible and silent’ malfunctions.
  • Programme the optimal operation of installations, monitoring their continuity.

Knolval The cloud-based intelligence system for efficient climate control

KnolvalTM  is a real building management system (BMS) dedicated to air conditioning.

Thanks to the Cloud and the Gateway, it turns valves into active, intelligent nodes that precisely control the amount of fluid flowing through the system’s branches and terminals.

Thus, KnolvalTM interacts with other system components such as environmental sensors, circulators and generators (boilers, heat pumps and chillers); it manages the correct amount of thermal energy in each area controlled by the valves; it optimises the overall thermal and electrical consumption.

If you already have a BMS, KnolvalTM pairs with it and does not force you to change it. If you do not have a BMS, KnolvalTM does not force you to buy one.

KnolvalTM  can be easily installed by the maintainance technician already working at the site. A software simplifies all the configuration and start-up steps.

KnolvalTM lives and operates on Google’s cloud, so you can avoid buying a server and installing software, updates or antivirus. Instead, you benefit from far greater computer security.

KnolvalTM is suitable to a wide variety of applications and systems. With its cloud based strategies for optimisation, the system automatically conforms to the operating conditions.

How can the effectiveness of heat recovery systems be improved by KnolvalTM?

A very interesting application of KnolvalTM is in installations where there are heat recovery systems: water-cooled chillers, air compressors, etc.. KnolvalTM makes it possible to regulate the temperatures on the circuits feeding the recovery system, maximising the efficiency of the heat exchangers and significantly increasing the free energy available.

Applied to the air conditioning system of Cimberio S.p.A.’s Berzonno plant, KnolvalTM has increased energy recovery by 75%.

The case of Cimberio S.p.A.

It’s 2018. The historic mechanical company Cimberio S.p.A. contacts Enersem to improve air conditioning in the warehouses of its factory in Berzonno, in the province of Novara. At their disposal there are intelligent valves developed by Cimberio as part of the HORIZON 2020 project, which Enersem engineers bring to the cloud. Thus the KnolvalTM system was born and, thanks to the use of intelligent valves and their remote management, it allows Cimberio to increase heat recovery from air compressors by 75% and decrease circulation pump consumption by 90%.

With KnolvalTM you buy:

Field Hardware

Electronic balancing valve and actuator, flow meter and temperature sensors.


A multiprotocol controller for cloud connection, data centralization, connection with BMS (if present), data storage, and service continuity.

Clima Start

The cloud-based software in Start module enables system configuration and management, ensuring automatic system balancing; reduction of “low delta T” syndrome; notification of malfunctions of all system components.

You can also purchase optional software modules, to meet even more specific needs:

Accounting Plus

It is an optional package for heating and cooling energy consumption accounting, which is particularly important in multi-tenant buildings, because it enables customized reports and estimation of future consumption. It analyzes consumption, savings achieved as a result of implementing improvement actions, comfort and air quality. By setting the frequency and type of data of interest, reports can be created to share within the company and with each tenant.

Energy Plus

This is an optional package for data monitoring and analysis, with dashboards featuring relevant and easy-to-read graphs and indicators. Thanks to the Knolval system and data from the BMS, it enables:

– analysis of consumption and operation of the building’s HVAC systems, such as boilers, chillers, AHUs;

– identification of malfunctions or potential optimizations;

– communication of the most effective improvement actions to the building manager. E.g.

changing power-on times, calibration of climate compensation curves, adjustment of air flow rates.

It is worth installing KnolvalTM if your rooms:

  • exceed 1000 m2.
  • are air-conditioned during summer and/or winter.
  • do not use an all-air air-conditioning system or unit heaters with gas burners.
  • do not use air/air heat pump systems.

KnolvalTM is the result of the cooperative intelligence of Enersem, a spin-off of the Politecnico di Milano University, and Cimberio, a world leader in the production of brass valves and components.
