Description
AKOCORE AKO-16526 with electronic expansion
The AKOCORE AKO-16526 controls the cold room temperature and the electronic expansion valve from the same wall-mounted unit. It can also work with a thermostatic valve and regulate electronic evaporator fans or a drive through its analogue output. It keeps suction pressure and temperature stable, reducing compressor work and consumption.
Main features
- Control of electronic expansion valves by pulses (PWM) or stepper (with external driver via 0-10 V / 4-20 mA output)
- Accepts most pressure transducers: 4-20 mA, 0-5 V, 0.5-4.5 V, 0-10 V and 1-5 V
- Ultra-fast superheat probe and dedicated PID algorithm to keep superheat at its optimum
- More stable suction pressure and temperature: less compressor work and lower consumption
- 0-10 V / 4-20 mA analogue output for electronic fans, drive or EEV driver
- 11-step guided start-up
- Remote maintenance, alarms and reports with AKONET.Cloud (via AKONET.Edge)
Applications
- Chilled and frozen cold rooms
- Integral panel (condensing unit and evaporator) or service panel (solenoid and evaporator)
- Air, electric heater or hot-gas defrost
- Temperature control with thermostatic or electronic expansion valve, with or without regulated evaporator fans
