The Leitenberger Smart Pressure Gate 901_002 is a revolutionary pressure control unit featuring integrated electronic monitoring and a digital display. This device is a key component of modern refrigeration systems, capable of replacing traditional mechanical and electronic components, thereby significantly increasing operational efficiency and safety. In addition to the guarantee of „Made in Germany” quality, the device also incorporates the latest digital communication technologies.
The goal of the Smart Pressure Gate 901_002 is to reduce the number of refrigerant circuit components, minimize installation complexity, and optimize system performance.
Component Consolidation: Significantly reduces the number of individual components required. Replaces mechanical pressure gauges, pressure transducers (transmitters), double and single pressure switches, as well as EC fan speed controllers. This reduces installation time, material consumption, and the risk of leakage points.
Outstanding Accuracy: Provides extremely precise measurement, with only 0.5 % FSS (Full Scale Span – as a percentage of the total measuring range) measurement accuracy. This guarantees reliable high- and low-pressure monitoring.
Integrated EC Fan Speed Control: The built-in function enables optimal control of the refrigeration system, which directly contributes to the increase in energy efficiency. The fan speed can be adjusted to the current requirements of the system.
Digital Communication and Remote Monitoring: The built-in Modbus RTU interface (RS485) allows system data to be digitally monitored, logged, and analyzed. This facilitates remote monitoring and predictive maintenance.
Analog Control Signal: Two independent 0…10V signal outputs are available for high and low pressure control, which is ideal for connection to existing analog control systems.
Simple Retrofitting: The device design allows for simple integration into existing connections with minimal conversion requirements.
Wide Refrigerant Compatibility: Supports the most common and newest refrigerants, including: R134a, R404a, R407c, R22, R407f, R410a, R448, R449, and R507.
