To support the minimum ventilation in the poultry houses, Vostermans Ventilation introduces the Multifan Casing Fan 92, characterised by a compact design and which is delivered as a complete unit and easy to install.

The direct driven, on/off fan needs less maintenance compared to belt driven fans, said Vostermans. The fan is supplied with a new type of shutter that reduces air and light entrance from outside. The Multifan Casing Fan 92 consists of a solid construction.

Also, the company introduces a digital climate controller, Master-5, which is a main controller to which simple 0-10V modules (e.g. triac or frequency controller) can be connected. The Master-5 enables through a 0-10V signal, continuous variable climate control, based on temperature.

The Master-5 is equipped with an auto-cooling down correction, two programmable 0-10V output signals. One of the options is to connect several modules, to control and drive fans, transformers, winch motors and valves.

Additionally, the electronic air inlet controller, Relink-3i, enables the control of a motor-driven air inlet or curtain-based on a 0-10V input signal. The Relink-3i can control winch motors with and without potentiometer feedback.

With potentiometer feedback the position of the valve is determined by the value of the potentiometer. Without this feedback the position is based on the running time of the valve.

For integration in control panels a number of various modules are available: Frelink-4f (single phase frequency control), Trilink-2t (triac controller), Relink-2s and 2c (electronic step controller) and STW & STD (step transformers). The main advantage for control panel producers is that the modules are composed according to the "Plug and Play" principle; easy and fast integration without any rest materials.

Not only the purchase of unnecessary parts is avoided, time-saving is also effected through the universal module composition. The controls are applicable for both new and existing systems.
