What is it?
The TQ Environmental TQ 4200 is an advanced refrigerant leak detection system designed to monitor multiple zones simultaneously (up to 8 channels). It provides reliable detection of refrigerant gas leaks in commercial and industrial environments, such as cold storage facilities, data centers, supermarkets, and HVAC systems.

How does it work?
The TQ 4200 uses advanced infrared and/or electrochemical sensors to accurately measure a wide range of refrigerants, including HFCs, HFOs, and ammonia. Each channel can be individually configured through an intuitive user interface on the built-in display. Alarm signals can be transmitted to building management systems (BMS) via relays, Modbus, or other communication protocols. Thanks to its modular design, users can easily add or replace sensors as needed.

What problems does it solve?
Undetected refrigerant leaks are harmful to the environment, increase operational costs, and can pose safety risks, particularly with ammonia. The TQ 4200 helps prevent these issues by enabling early leak detection. This allows users to take timely action, reduce downtime, and comply with environmental regulations such as the F-gas regulation.
