160x69,5x76,5 mm PCT-1600 Pressure controller featuring 16 outputs (double suction and discharge) for mounting racks, which includes Sitrad connection; 16 configurable hour meters (working hours for each output); 3 pressure transducers (control) and 3 temperature sensors (safety); 6 configurable digital inputs; 3 operation modes for the compressors (sequential, according to capacity, and rotative output actuation according to operation time). It also enables you to configure night and day set points, allowing a great energy saving. It has a serial communication for connection to Sitrad. Application example: cooling racks. » Product manual

71x28x71 mm PCT-400R For cooling centrals, it features four stages and alarm output. It operates in independent pressure ranges, from 0 to 100psi (suction) or 0 to 500psi (exhaust). Ammonia refrigeration systems compatible. - Sensor sold separately. It has a serial communication for connection to Sitrad. Application example: cooling racks. » Product manual

71x28x71 mm PCT-420R For pressurization and/or depressurization, it features four outputs that can be configured for pressure control, with the last two able to be additionally configured as cyclic timer or alarm. The outputs configured for pressure control also feature an internal hour meter to activate the maintenance alarm and to perform automatic rotation of load activation. Ammonia refrigeration systems compatible. - Sensor sold separately. It has a serial communication for connection to Sitrad. Application example: water pumps, cooling systems, and fire prevention systems. » Product manual

71x28x71 mm PCT-100R Single-stage, from 0 to 500psi, it can be applied either in cooling systems, both in suction and exhaust, or in air compressors and water pumps control. Ammonia refrigeration systems compatible. Application example: pneumatic and industrial systems. » Product manual

71x28x71 mm PCT-410R For cooling premises, it features five control outputs (four digital outputs and one 0-10VDC analog output) for frequency inverter proportional control. In addition, it features one auxiliary digital output (NC contact) that can be used to indicate pressure out-of-range (under/over) or sensor not working. It enables you to save energy and enhance the equipment life since the proportional control allows the equipment power to be altered according to the motor RPM. This decreases the power ON cycles, reduces the mechanical wearing and avoids current surges when powering ON the equipment. It operates in independent pressure ranges, from 0 to 100 psi (suction) or 0 to 500 psi (discharge). Anmonia refrigeration systems compatible. - Sensor sold separately. It has a serial communication for connection to Sitrad. Application example: cooling racks.
