Ordering Information
Kromschröder’s TC 410 has been discontinued, and the manufacturer does not seem to have plans to replace it. If you need replacement options, please Contact Us. If you are considering equipment for a new installation, you may be interested to know that many next generation flame safety/burner control devices offer tightness check as an integrated feature. Installing and monitoring valves with integrated proof of closure is another way you might satisfy code requirements, instead of using tightness check.
Description
The tightness control TC checks the fail-safe function of both valves before each start-up or after each shut-down of a system with two safety valves.
The aim is to identify an inadmissible leak on one of the gas valves and to prevent burner start. The other gas valve continues working properly and takes over the safe shut-off of the gas supply.
TC is used in industrial thermoprocessing equipment, on boilers, and on forced draught burners.
Standards ISO 13577-2, EN 746-2 and EN 676 stipulate tightness controls for capacities over 1200 kW (NFPA 86: from 117 kW or 400,000 Btu/h in conjunction with visual indicator).
Pre-purge of the combustion chamber can be dispensed with under certain conditions in accordance with EN 746-2, if a tightness control is used. In this case, the system must be vented into a safe area.
TC 4
Tightness control TC 4 consists of detection circuitry and can be installed in the control cabinet, separately from the system. An external pressure switch takes over the mechanical pressure test between the valves. Tightness control TC 4 is independent of gas type and inlet pressure and can be used for a test period of up to ten minutes with a large test volume.
