Sporlan electronic expansion valve controller

The Subcool Control provides liquid temperature and superheat (pressure-temperature) control for most common refrigerants. In all applications, use a normally closed solenoid valve upstream of the electronic expansion valve to ensure positive shutoff of refrigerant flow during power loss. This is the perfect solution for installations that require precise electronic control. ETS is a series of electric expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications. The electronic expansion valve (EEV) operates with a much more sophisticated design.

EEVs control the flow of refrigerant entering a direct expansion evaporator.

They do this in response to signals sent to them by an electronic controller. A small motor is used to open and close the valve port. The motor is called a step or stepper motor. THERMOSTATIC EXPANSION VALVES:. The controller operates an electronic expansion valve to control superheat.

The EXD-Uis a universal driver that enables the operation of Emerson stepper motor driven valves used in applications such as solenoid valves, electronic expansion valves, hot gas bypass or evaporator pressure regulator as capacity control, crankcase pressure regulator, heat reclaim regulator, and liquid level control. Expansion Valves, and are installed before the distributor and evaporator just as one would install a Thermostatic Expansion Valve. Location should be planned to provide serviceability and to allow controller installation within the maximum cable length of forty feet.

The valves are directional, and the inlet is clearly marked. Select the valve model connected via. Superheat Controller with Display (unipolar, bipolar EEV). Low superheat, higher evaporating pressure, and better COP The advantages of an electronic superheat controller are obvious. The evaporator is always optimally filled with refrigerant.

Electronic expansion valve DHP-R. If the controller has an emergency power supply (Vdc), this closes the expansion valve , and displays the CLE message in the event of a fault in the electricity supply. Initial configuration This equipment has been designed to regulate the electronic expansion valve via overheating control of the refrige-rant gas in the evaporator. Once the wiring harness is changed out changes still have to be made to the controller to accept the new valve.

The current range is available with different capacities, and can be used with all common refrigerants (R410A, R407C, R404A, R134a, R22). Refrigerant 7Ammonia Products. There are 3electronic expansion valve suppliers, mainly located in Asia. The top supplying countries are China (Mainland), South Korea, and Greece, which supply , , and of electronic expansion valve respectively. CAREL electronic expansion valve.

SPORLAN and ALCO electronic expansion valves can be. Sporlan expansion valve can be used. The EEV have an electronic controller and step motor instead and respond to the sensors.

I read they the valve has very accurate control of refrigerant that flows through it, and most of these EEVs have 5steps of control and each step is 0. The IB and TCB accept a 4-milliamp, or 0-volt DC inputs and stroke the valve proportionately to that signal. Applicable to a variety of valve control, such as Danfoss and Sanhua etc. Carel Expansion Valves direct from the only factory authorized on-line store. The ESX expansion valve provides precise flow control for virtually every refrig-eration, air-conditioning, and heatpump ap-plication, from basic to complex, and in a wide range of environments. Koury, Luiz Machado, Alexandre C. More than 20hospitals, schools, manufacturers, building managers and service professionals rely on Acme for their combustion control needs.

Using anRSV electric expansion valve in place of a traditional mechanical expansion valve , ensures the system is at the desired superheat, over a much wider range of operating conditions. Designed for refrigeration and air conditioning applications. The RSV is engineered for use with common HCFC and HFC refrigerants.

An Avalve with a high-pressure setting would serve this purpose. Its reinitialization should only occur when the rack is offline. ELECTRONIC TEMPERATURE CONTROLLER WITH TEMP INPU: Honeywell, Inc. The Subcool-O-Matic was designed to increase the efficiency of supermarket refrigeration. This ensures a dry vapor reaching the compressor suction.

Oil return from the evaporator is also improved since the veloc-ity in the evaporator is kept high by the hot gas. Follow the manufacturer’s instructions for setting up your valve controller to complete the system upgrade. Not super familiar with Novar, but most controllers will show a log of the intended percentage that the valve is open. Sku: 410- New in box, with instructions.

Secondary Loop Case Control (Glycol or CO2) 4. EEV’s are modern high performance metering devices. We carry top quality expansion valves from the best manufacturers in the industry. Universal indepedent electronic expansion valve controller US $73. VDC (VDC = valve opening, VDC = 1 valve opening).

The MCS-EXV-DRIVER also supports overdriving on full. XEV22D permits to regulate the superheat (SH) of the fluid that runs into refrigerating unit in order to obtain optimized performance and a functioning of the evaporator independent by climatic or load conditions. This is the series of articles that describes what the throttling valves are for the refrigeration and air conditioning systems. It also describes the functions of the throttling valves and also its types like capillary tube, automatic expansion valve , thermostatic expansion valve etc.
