1. ETR Negative Pressure Vacuum System Description
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
2. ETR Negative Pressure Vacuum System Feature
The main components adopt high-quality brands to ensure product quality;
The negative pressure generation process is controlled by microcomputer and fully automatic without human intervention.
The pressure is stable, freely adjustable, safe and reliable.
A three-phase 380V low-voltage power supply with low noise and low energy consumption is used.
Product standardization, serial production, on-site construction is simple and convenient;
Dynamic control of cooling water temperature and water volume to ensure that the vacuum pump is running at its best;
Automatic conversion between units, automatically start the next unit replenishment according to the rate of decline in gas consumption;
With process flow dynamic display, running data storage, fault protection and abnormal alarms;
Modular design, flexible configuration between multiple units, linkage operation;
Open data communication interface for remote management of devices.
Automated electrical control system with high intelligence;
Remote cloud monitoring platform: device monitoring through computer, with mobile APP mobile intelligent monitoring function, real-time monitoring of equipment operation, with abnormal operation alarm function
