Kromschroder Tightness Control Unit (Replaces TC 410-1T, Item Code
84765810)
Product Introduction
The Kromschroder Tightness Control Unit is a specialized device
designed to verify the integrity of two safety valves in gas burner
systems, ensuring compliance with safety standards and preventing
gas leaks. EU-certified and engineered for reliability, it features
adjustable test parameters to adapt to diverse system requirements,
making it a critical component in industrial heating and combustion
setups.
Key Features
Dual Safety Valve Testing:
Checks the fail-safe function of two safety valves to detect
inadmissible leaks, preventing burner startup if a valve is faulty.
Ensures redundant safety: If one valve leaks, the second valve
maintains safe gas shutoff.
Adjustable Test Parameters:
Test Period: 10–60 seconds, customizable to match system volume,
leakage rates, and inlet pressure.
Test Timing: Configurable to run before or after burner operation,
accommodating quick system startups.
Self-Monitoring Electronics:
Built-in diagnostics for self-checking, ensuring the control unit
itself operates correctly and reducing false negatives.
Plug-In Housing:
Compact, modular design for easy installation and replacement
(direct replacement for TC 410-1T).
