Actuador eléctrico inteligenteAMEi 6 iNET
El actuador AMEi 6 iNET para el equilibrado de red inteligente permite el ajuste remoto dela presión diferencial (Δp) en los controladores AFA 2, AFD 2, AFP 2, AFPA 2, AFPB 2, AFPQ 2 yAFQMP 2 utilizados en sistemas de calefacción/ refrigeración de distrito.
Los cambios en el consumo de calor requieren cambios en la distribución de calor. Por lo tanto, el valor de Δp debe optimizarse en cada derivación. Con iNET, el valor de Δp se puede ajustar de forma remota. Entrada para optimización de la bomba.
AVPB, AVPB-F (PN 16)
AVPB (-F) is a self-acting differential pressure controller with flow limitation primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).
AVPB, AVPB-F (PN 25)
AVPB (-F) is a self-acting differential pressure controller with flow limitation primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).
AVPQ (PN16)
AVPQ is a self-acting differential pressure and flow controller primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with two control diaphragms and handle for differential pressure setting (fixed setting version (available on special request) is without handle).

AVPQ, AVPQ 4 (PN 25)
AVPQ (4) is a self-acting differential pressure and flow controller primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with two control diaphragms and handle for differential pressure setting.Intelligent electrical actuator AMEi 6 iSET
AMEi 6 iSET actuator for intelligent optimization of the District Heating/Cooling substation operation. Automatic adjustment of Δp setting on AFP 2, AFPB 2, AFPQ 2 and AFQMP 2 controllers, used in DHC systems.
Solution for dynamic DH systems with wide span of min - max flow (Domestic Hot Water service) and for systems with improperly sized control equipment (oversized control valves, wrong valve selection/characteristic, poor control ratio...).
Auto stabilization function monitors control signal and stabilizes oscillations at the partial/ low load operating conditions, by adjustment of the Δp over the motorized control valve (MCV).
Constant-real time MCV operation improvement led to more stable control without oscillations and flow delivered up to the real needs (overflow prevention).
This results in stable temperature conditions on the secondary side, improvement of ΔT on the primary side and longer lifetime of installed equipment.
