CAREL EVD0000T31双阀控制器  英文介绍

CAREL EVD0000T31 is a dual valve controller in the CAREL EVD Evolution Twin series, with the core feature of independently driving two electronic expansion valves with one controller. It belongs to the EVD0000T series, and the T31 suffix corresponds to specific communication and configuration versions.

Product Features

Dual valve independent control

Equipped with two bipolar stepper motor drivers, it can independently manage two electronic expansion valves, adjust their respective degrees of superheat, and optimize the performance of the refrigeration circuit.

Overheating control with multiple protections

Supports superheat control and has high pressure, low pressure, and low superheat protection functions to prevent compressor liquid hammer and abnormal operation.

Support special control functions

It can be configured with hot gas bypass, evaporator pressure regulation, and control of downstream valves of gas coolers in transcritical CO2 systems.

Graphic LCD detachable

Equipped with a detachable graphic LCD display screen, it supports multiple language interfaces and online parameter assistance, and can also copy configuration parameters from one controller to another through the display screen.

Easy debugging

When starting, only 4 parameters need to be selected: refrigerant, valve type, pressure sensor type, and application type. If using CAREL valve, only 3 parameters are required.

Product Specifications

Model attribution

EVD Evolution Twin series, EVD0000T31。

Valve drive

Two bipolar stepper motor drivers independently control two electronic expansion valves.

Installation Method

DIN rail installation, equipped with pluggable screw terminals.

Pressure sensor

Supports 4 to 20 mA proportional pressure sensors, which can be shared by multiple drivers.

Communication and Integration

CAREL controller can be connected via LAN, supporting optimized control of Digital Scroll compressor.

Application Areas

chiller

Control the superheat of the evaporator to improve energy efficiency and operational stability.

air conditioning system

Optimized control with Digital Scroll compressor, suitable for commercial air conditioning.

refrigeration equipment

Electronic expansion valve control for refrigeration devices such as cold storage and refrigerated cabinets.

CO2 transcritical system

Support subcritical and transcritical CO2 refrigeration circuits, including downstream valve control of gas coolers.

Multi loop system

One controller manages two circuits, suitable for dual circuits or situations where overheating and hot gas bypass need to be controlled simultaneously.

The core of EVD0000T31 is one control two, saving cabinet space and costs. When selecting, pay attention to confirming the compatibility between the communication version corresponding to suffix T31 and the existing system.
