Low and high pressure pressure switches are electromechanical devices used to monitor high and low side pressures in refrigeration systems.
They are equipped with electric contact sets that open or close depending on the mechanical performance resulting from the increase or decrease of the refrigerant gas pressure on a diaphragm.
Contactors (Magnetic Keys): It is an electromagnetic key of indirect control, that is to say, its use allows to put and / or remove of operation elements or loads, being able to carry out this operation in the place of the installation or the distance, of one or more places.
Operation
It is provided with a set of fixed and movable electrical contacts that open and / or close depending on the magnetic action of a coil on a mobile core where the movable contacts are fixed
Thermal Relays (Overloads):
They are electronic or electromechanical devices that have as main purpose the protection of electric charges against the effects of short or long duration overload, phase failure and blocked rotor.
They are manufactured to be directly coupled through pins that fit the contacts 2 (T1), 4 (T2), 6 (T3) of the force contactors used in the load drive.
Relay Lack of Phase:
The lack of phase relays act in the control systems in the protection of motors against the harmful effects of phase and / or neutral lack and phase asymmetry. The sensitivity of the degree of asymmetry between is adjustable through a knob adjustment on its front knob. They have electrical switches (11, 12 and 14) controlled by their electronic circuits that open or close due to their protection.
NH and Diazed Fuses
They are devices intended to limit the current of a circuit, interrupt it in case of short circuits or overloads of long duration.
Circuit breakers
They are maneuvering and protection devices, equipped with a thermomagnetic relay, capable of switching on and off under abnormal circuit conditions.
Auxiliary switches type pushbuttons
They are Manuel command switches whose function is to interrupt or establish
Momentarily, by pulse, a control circuit, to start,
Interrupt or continue an automation process.
Temperature Controller
Controllers or microprocessors are devices that integrate the
Control circuit of some refrigeration systems. Versatile and practical
Can monitor the installation with data storage,
Control the operating time to control the operating time of the system, the
Machine performance, and product temperature.
Oil pressure switch: interrupt the circuit if there is a deficiency in the lubrication of the compressor. It controls the pressure difference between the sump and the output of the lubrication pump.
