The CVQ valve is operated by the EKC controller. Please notice that a power failure will cause the CVQ pilot valve to fully open ICS / PM. If it is required that. Type Code, EKC Weight, Kg.

If connection sizes larger than 54 mm are required for the suction line, it is recommended that you dahfoss a solution with a main valve. In the control menu, not only are basic adjustable values displayed, but it is also possible to precisely influence certain events by adjusting stability and amplification factors. This valve is equipped with a stepper motor and is controlled by an electronic controller e.
Page 13 If the actual application has a requirement re- garding max. The controller is operated using two push buttons. It is possible to equip the control with a LON module and record the appropriate data using a master unit and to intervene in the control system remotely using a modem connection.
Precise media temperature control | Danfoss
Digital controller for refrigeration and defrost, 3 relays pages. However, in this case, more time must be planned for achieving the required reference value. However, applications in the food industry are also possible.
Suction line installation In the case of a media temperature control for refrigerating plants with a pipe size of up to 54 mm, an electrically controlled valve e. Here, the main valve with pilot is also fitted in the suction line.
This also applies to products already on order 3361 that such alternations can be made without subsequential changes being necessary in specifications already agreed. Remote service is also possible for this control system.
In the case of this setting, a very clear undershooting of the outlet temperature of the evaporator is to be expected to facilitate fast refrigeration and ensure the reference temperature is quickly achieved.
Precise media temperature control
A fast-reacting temperature sensor e. Service The service menu of the electronic controller is of particular interest to the fitter upon commissioning or servicing of the plant. This point can be directly influenced with an electronic suction throttle system: To print the manual completely, please, download it.
Precise media temperature control. This can be done using special software type “Danfoss AKM”.
In applications such as this, constant nozzle air temperature from evaporators is the key to success. The advantage of this is very gentle cooling of unpackaged goods, in which any unnecessary dehumidification is avoided. Even with a temperature difference of just 1 K, the control forces a small opening to prevent the control from overshooting the set point.
Enter text from picture: P control involves standard regulation according to the deviation example: Due to tolerances in the actuator, the setting value must be 10 K lower than shown in the curve. This means that any fitter at the plant can intervene in the control circuit and view relevant data. By pressing ‘print’ button you will print only current page.
Special attention must be paid to the start-up phase of regulation. Therefore, the control gives the valve the command “open valve” in situations where the reference value is far lower than the actual value. Page 5 Due to tolerances in the actuator the value must be set 10K lower than indicated in the curves on page Controller for control of industrial evaporator 16 pages.
If the actual application has a requirement re- garding max. Precise refrigeration and air conditioning is essential for many applications and demand is constantly increasing.
Home page Service and support Case studies Precise media temperature control. The “D component” in PID control also optimises the control characteristics in the case of a sudden change to the reference value.
Page of 16 Go. The second option only allows slight undershooting. Continuous electronic valves The “KVS” is a continuous valve with which even the smallest fluctuations in evaporation pressure can be avoided. For safety, a maximum defrost duration can also be set in the refrigeration controller, which ends the defrosting process in the case of a defective defrost sensor or a similar fault.
This means that this media temperature control can be integrated in complex Danfoss control system networks. Refrigeration specialists know that the topic of “humidity” plays an important role in refrigeration, especially where unpackaged goods, meat, vegetables and fruit are concerned. Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material. Operation The controller is operated using two push buttons.
A completely open valve ensures maximum refrigeration and therefore the lowest possible outlet temperature in the actual load situation.

The “EKC ” control has three different transient processes available. After defrosting, the drip-off time begins. In simple terms, the purpose of the drip-off time is to drain off ice that has turned into water on the evaporator via the condensate drain.
A system like this is suitable for ventilation and comfort air conditioning plants elc conditioning cabinets, as well as for fruit and vegetable storage.
