Ventilation and climate controls

Ventilation control systems - decentralised, user-independent, energy-efficient

ZILA offers a wide selection of climate controls and ventilation devices for a variety of industries and applications.

Decentralised, user-independent, needs-based ventilation and dehumidification with climate controls

Our climate controls are energy-efficient as they work in a user-independent, needs-based and controlled way. They come with climate sensors and are suitable for decentralised dehumidification and ventilation and cooling. Our devices are ideal to be used in many different locations - from new constructions, buildings requiring refurbishment, energy-efficiently renovated and modernised buildings, to halls, churches, archives and conference rooms. To sum up, should you decide to use our ventilation devices, you will preserve the fabric of the building concerned and create a comfortable feel-good climate.

Radon-free rooms thanks to a climate control in your house

Radon is an odourless, tasteless, colourless noble gas with high density. It is a radioactive decay product of radium, thorium and uranium. Radon can be released into the atmosphere through gas-permeable soils due to its nature. If the earth's surface is covered with buildings, radon may also enter cellars and the basement.

In some regions of Germany and Europe, the radon concentration in residential buildings is so high that some of them even become uninhabitable. For this reason, solutions reducing the radon load to a harmless minimum are urgently needed.

The climate control KST-20 Vento/RN allows the room to be ventilated safely and user-independently. This not only creates a comfortable feel-good climate, but also ensures that the air we breathe is healthy and fresh.

More information about radon, specified limits and the application of our climate control can be found in our blog:

Simple CO2 level monitoring with a climate control

Carbon dioxide can become dangerous, but it also has useful properties. In public buildings and recreation rooms, the concentration should be kept low. In industrial applications, however, accurate monitoring and targeted implementation can have many advantages. It is therefore essential to take accurate and precise measurements. The climate control KST-20 Vento/CO2 opens up possibilities to create the ideal climatic conditions for lots of individual situations.

KST-20 Vento

Climate control for dehumidification, ventilation or cooling of any kind of rooms

Front view of the climate control with display and operating keysaH_Controlled TechnologyRn-Protected Technology

Multifunctional climate control KST-20 Vento with aH-Controlled Technology for automatic, controlled and needs-based ventilation, dehumidification and cooling of commercial, industrial and private rooms.

The climate control is comes with with separate connections for supply and exhaust air elements up to a maximum of 500W as well as further connections for all common ventilation devices (see product details). It is possible to display the current measurements and set various parameters at any time using the operating keys and display. Due to its comfort functions such as frost and dry protection, the climate control KST-20 Vento can be applied flexibly in almost any living, working and industrial areas

It is also available as KST-20 Vento with radon ventilation, equipped with an additional radon sensor. Besides the absolute humidity, the radon concentration inside the building is measures as well.

Another option is the KST-20 Vento with air quality monitoring. It contains a CO2 sensor and can measure both the absolute humidity and the carbon dioxide content.

KST-20 Calima

Climate control room dehumidification and living space ventilation according to DIN 1946-6

Front view of the climate control with LED displaysah_Controlled Technology

Due to the modern design of its housing, the climate control KST-20 Calima is especially suitable for ventilation and dehumidification in all living spaces. The device is factory-set and works automatically wherever it is needed. For this reason, the climate control KST-20 Calima has essentially been designed without display and operating elements, so that it is safe to use in public buildings as well. The automatic mode ensures a comfortable feel-good climate even when the user is not there (optimum temperature/humidity ratio). Two LEDs on the housing indicate the current status of the device. Manual ventilation processes can also be carried out with a button on the unit.

By using modern plug connections, one-step, two-step and speed-controlled fans can be connected very easily.

  • Two control or switching outputs up to 500W each (230V or 0...10V)
  • Two versions available: 230V or 0...10V
  • Suitable for all areas of a house (living areas and non-living)
  • Factory-set values
