  • PCT-3000 Plus

    Short Description:
    Controller designed for racks of compressor featuring 4 pressure transducers and 30 controlling outputs of which 26 are digital relay, and 4 are analog (0~10) . The settings of each analog output can be set by the user to proportional controlling of the compressors, and fans (1 suction and one discharge, 2 suction and 1 discharge; 3 suction and one discharge; 2 suction and 2 discharge). It has 4 temperature sensors, which are two for suction and two for discharges. Also it has a dedicate temperature sensor to display the temperature of the liquid line to control the sub-cooling. Depending on the settings of the
    setpoint ( temperature to be achieved) and hysteresis, these sensors will work, for example, in 2 solenoid valves. The overheating is controlled by sensors of temperature and transducers in the suction line, specially in cases where the compressor is installed far from the evaporator, for example, in supermarket stores. This instrument allows up to 4 alarm outputs ( one for each line ), beyond that, it works in a system with mixed outputs (on/off), as an example, allowing 4 compressors ON/OFF, and a compressor with variable capacity working along other. It also allows configuration of up to 2 outputs for the adiabatic system of the condenser (discharge pressure as a reference). This set provides a better performance and energy savings based in seasons. It operates in independent pressure ranges, from 0 to 100psi or from 0 to 6,9bar, using a SB69-100A transducer, or from 0 to 500psi or from 0 to 34.4bar, using the SB69-500A transducer. It has a serial communication for connection to Sitrad
    *Included 1 transducer for suction and 1 for discharge.

  • MT-444

    Short Description:
    Temperature controller for beverage exhibitors, with programming logics that allow a considerable power saving. Among them, we can highlight saving set point functions, changes in the door status saving mode, cyclical functions for fans, smart defrosting and anti-freeze protection functions for bottles.
    With an enhanced design and touch screen keys, it features 2 modules, the first is a power module – where the 4 outputs for the compressor, fan, defrost and lamp activation are located – and a frontal module, where the temperature, sensors, door switch and the connection for the programming key can be found. The programming key allows technicians and manufacturers to quickly set the controller and copy parameters from other equipment. The True-RMS voltage monitoring circuit allows you to protect the compressor against sub and over voltages introduced by the local power grid.
    Through an internal sound signal (buzzer), the controller send an alarm when the refrigerator door if it is open after the configurable time has ran out or when the room temperature is out of the set limit.
