Chaudière électrique à eau chaude emballée
A floor-standing electric boiler package that heats closed-loop water for cleanroom AHU coils without combustion, flues or on-site fuel storage.
- Flue-Free Electric Heating
- Staged Immersion Elements
- Compact Stainless Vessel
- Integrated Hydronic Safeties
Introduction de produit
The packaged boiler encloses a stainless pressure vessel, replaceable immersion elements, contactors or electronic power control, circulation connections and safety devices in one floor-standing cabinet. Electrical energy is transferred directly into the closed hydronic loop, avoiding combustion air and exhaust infrastructure. Multiple element stages follow heating demand, while a touchscreen displays water temperature, operating state and alarms.
Key Features
Multiple element stages provide smaller output increments and distribute electrical loading.
A stainless vessel, relief valve, low-water protection and temperature limits form an integrated hydronic package.
Front and rear access panels expose the heater flange, terminals and water connections for service.
Préoccupations du client produit
Electric hydronic heating must fit available power, protect the vessel and respond smoothly to a variable coil load.
A facility cannot install gas piping, combustion air or a flue.Immersion heating produces hot water inside a sealed cabinet using only electrical and hydronic connections.
One large contactor stage causes temperature overshoot.Several element stages or proportional power control match output to the changing loop demand.
Low water level exposes heater elements to damaging temperature.Flow and low-water protection disable power before elements can operate dry.
Scale on the element sheath reduces transfer and service life.A removable heater flange exposes the complete bundle for inspection and cleaning.
