Danfoss EKC312-084B7250 electronic superheat controller introduction

The controller and valve can be used wherethere are requirements to accurate control of superheat in connection with refrigeration.

• Processing plant (water chillers)

• Cold store (air coolers)

• A/C plant

Danfoss EKC312-084B7250 electronic superheat controller Features

The evaporator is charged optimally – even when there are great variations of load and suction pressure.Energy savings – the adaptive regulation of the refrigerant injection ensures optimum utilisation of the evaporator and hence a high suction pressure.The superheating is regulated to the lowest possible value.

Danfoss EKC312-084B7250 electronic superheat controller Operation

Superheat function

y Adaptive superheat

MOP

The MOP function limits the valve’s opening degree as long as the

evaporating pressure is higher than the set MOP value.

External start/stop of regulation

The controller can be started and stopped externally via a contact

function connected to input terminals 1 and 2. Regulation is

stopped when the connection is interrupted. The function must be

used when the compressor is stopped. The controller then closes

the solenoid valve so that the evaporator is not charged with

refrigerant.

Alarm relay

The relay for the alarm function works in such a way that the

contact is cut in in alarm situations and when the controller is

de-energised.

PC operation

The controller can be provided with data communication so that it

can be connected to other products in the range of ADAP-KOOL®

refrigeration controls. In this way operation, monitoring and data

collection can be performed from one PC – either on the spot or in

a service company.
