Temperature and electronic expansion controller

TEMPERATURE CONTROLLER AND ELECTRONIC EXPANSION FOR COLD ROOMS

AKOCORE

AKO-16526

ATTRIBUTES AND ADVANTAGES

Ease of installation: commissioned in just 11 guided steps in the most simple manner possible, saving time during the installation and avoiding set-up problems or errors.
Flexibility in the installation and application: allows a wide range of possibilities for controlling:
- Pulse electronic expansion valves (PWM type)
- Electronic fans or variator using one analogue output (0-10V / 4-20mA)
- Stepper type electronic expansion valves (requires external Drive)
- Accepts most pressure sensors available on the market: 4-20 mA, 0-5 V, 0.5-4.5 V, 0-10 V, 1-5 V
Improved cold room performance: the ultra-fast probe for measuring overheat along with a PID algorithm specifically designed for this application, allow keeping the evaporator at the optimum overheat point at all times, maximising its efficiency while preventing any kind of liquid hammering in the compressors. This way, the suction pressure and temperature is kept practically constant, reducing how much the compressor has to work and therefore, the electrical consumption.
Monitoring and preventive maintenance: Allows carrying out maintenance remotely through the AKONET.Cloud, in addition to receiving alarms and reports (must install AKONET.Edge)
