Chillventa is coming

We invite you to see our latest innovations of air coolers for different applications at Chillventa in Nuremberg.


FHV/T, DHN and DLK/T are available with built in expansion valve and superheat controller. No matter if you use HFCs or CO2 as a refrigerant, you can simplify the mounting and start-up of a refrigeration plant with these superior solution. Another big advantage is, to install the adaptive control that can save energy in many applications. The superheat controller can be connected to the cooling controller via RS 485 MODBUS and you get extensive features to monitor the sound operation of the unit. Especially at CO2 applications a full connected network of sensors is state of the art.

VM/ VW/ VD plus

Our smallest units VM/VW/VD are often applied in ambients where they are prone to corrosion. The new VM/ VW/ VD plus heat exchanger is lacquered with a thin protective coating. This extends the lifetime of these units in fairly corrosive environments.


Our special air cooler SV, also known as "the S stands for sausage evaporator", is often installed in wine cellars. In this application sound is an issue. The new SV prototype which we will present at Chillventa is equipped with new sound optimised fan.

HKN/D controller

For our fan coil units HKN/D we will present the improved mulitfunctional room temperature controller RCN 155- L- RO. With it you can control all the features of the HKN with a steady signal. Through the controller we can adapt the unit to your needs like operation or error signals integration in a LON network and many more. We hope to meet you personally at Chillventa hall 6 booth 6-208 in person to give you more introduction about our range of products. See you in Nuremberg.
