GGW / AGW glycol protector
The GGW / AGW glycol protector is an extension to the oil protector. In addition to preventing the escape of light liquids (e.g. oils), it also prevents the escape of water-glycol mixtures or other water-soluble substances, in accordance with legal requirements.
The system monitors the water-glycol circuit by means of a digital pressure (or GES) sensor. The information supplied is processed by the control module. System-related pressure fluctuations are distinguished from an emergency scenario (leakage).
In this case, the safety valves used are immediately closed. Escaping water-polluting substances are retained in the glycol protector, and the operator is alerted.
The water-glycol circuit is constantly monitored by modern sensor technology. The switch box is IP65-protected and UV-resistant, and contains a microprocessor, relays, terminal blocks and the complete internal wiring. The microprocessor evaluates data from the sensors. If the control unit reports a leakage in the liquid circuit, the drain valves are locked and an alarm contact is activated. As such, the leaking water-glycol mixture is safely retained. Special switching technology prevents the valves from opening again without the operator having given spproval. The alarm is shown as plain text on the microprocessor display. Up to two liquid circuits can be monitored with the GES or pressure sensor.
To meet the requirements of safety systems, in the event of a power failure, microprocessor defect, cable break, faulty valve control or sensor defect, the drain valves are automatically closed, locked and the alarm contact activated.
The drain valves are protected from external conditions by a stainless steel or aluminium housing and are equipped with isolated contacts for alarm and operating messages. An additional defrost heater is not required for year-round operation of the valves.
The largest possible amounts of precipitation in Germany are safely collected or discharged.
The GGW / AGW glycol protector meets the requirements of Section 62 ff of the German Water Resources Act (WHG) and the German Systems Ordinance (AwSV). The strict guidelines of the German Ordinance on Installations for Handling Water Pollutants (WasgefStAnlV) are also fulfilled. The intelligent pressure monitoring system can also be accessed digitally via the internet at any time.
