Electronic panel AKO-16526 + EEV controller 100–240V AKO Spain

The AKO-16526 controller can be used for the direct control of a PWM-type electronic expansion valve (EEV). It is necessary to use an external driver for controlling a step-type valve. The controller instructs the driver on the required valve opening of the EEV (electronic expansion valve), depending on the pressure and temperature at the evaporator outlet, in order to achieve the superheat value set in parameter Sh. The optimal superheat value increases the efficiency of the evaporator.

This is a control panel capable of managing complete refrigeration systems for cold storage or freezing applications, and it can also be used as a sub-panel in installations with central (multi) systems, controlling all functions (including the EEV – electronic expansion valve), such as: evaporator heaters, compressor, solenoid valve, crankcase heaters, single-phase evaporator fans, air or electric defrost systems, cold room light switch, etc.

It can control two evaporators with one compressor via a third sensor.
It can connect and be controlled via Bluetooth (including remote access via mobile “sharing”) and can also log data via the CAMM MODULE (optional).

It does NOT include SELD-DRIVE (only in model AKO-16526A).
