Enhanced Safety: Facilitates rapid flame detection to ensure the gas valve closes instantly if combustion is not verified

it features a non-linting aerated pilot design that maintains a stable pilot flame even under fluctuating gas pressures

OEM Compatibility: Directly replaces Carrier HC43AE134 parts without mounting modifications

you can upgrade to a higher voltage rating like 440Vac as long as the capacitance (30/5 MFD) and physical dimensions match

Velocity Boiler Works (Crown) 400821 LWCO 326058-758 Is the Trane SHE5330 aMaintain critical safety in steam systems with the Velocity Boiler Works 400821 LWCO. This Hydrolevel CycleGard CG 400 series control uses advanced conductance sensing technology to monitor water levels without the mechanical failure points found in traditional float style cut offs. As a veteran technician knows, surging and foaming in steam boilers can lead to false readings; this unit leverages Intermittent Level Test (ILT) logic to periodically
