Custom solution

Custom solution

A decentralised indoor climate solution is suitable for single-storey large spaces of all types – from workshops to high bay warehouses. The system supplies fresh air, extracts used air and provides heating and cooling. The modules are individually combined to meet any requirement.

Efficient technology

Efficient technology

At the heart of the Hoval indoor climate systems is the patented Air-Injector for ventilation without the draughts. It is effective at ensuring the air that enters the room is fresh and – if necessary – at the right temperature. The sophisticated technology saves space, energy and effort.

Reliable & economical

Reliable & economical

The Hoval software controls the individual units and ensures that their interaction is optimal. For the highest environmental standards and minimal operating costs, low-emission energy sources and condensing technology are used.

The units work well with each other but can also be controlled separately, meaning that the exchange of air in the hall is ensured at all times.

How a decentralised indoor climate system works – decentralised and modular

Installed in a select number of specific locations, these units ensure optimum climate conditions throughout the entire hall, even where different requirements are involved. The supply and extract air handling units, supply air units and recirculation units are equipped with optimised air distribution and, if desired, their own heat and cold generation system based on a heat pump.

Patented air supply and distribution from the Hoval Air-Injector

Heating, cooling and ventilation in one unit

The Air-Injector’s powerful, efficient air distribution allows the components to cover a large operating area, meaning that only a relatively low air flow rate is required. This saves not only on investment costs, but also on drive energy and operating costs too.

Potential energy savings for specific applications can quickly and easily be calculated.
