Vapac Electrode Boiler LE09 9kg/hr

Vapac’s electrode boilers provide reliable and responsive close control humidification production. 

The LE range incorporates an intelligent combination of supplying, boiling and draining to minimize wastage of water and energy.  Water level control technology gives a performance turndown of between 20% and 100% of designated unit performance.

The LEP Close Control model has a unique Pulsed Energy control providing infinitely variable steam output from 8% to 100% of full capacity. Typically, the VapaNet Pulsed Energy (LEP) can be used in close tolerance applications.

The option of the VapaNet control system provides instant performance data via an alpha numeric display (fitted as standard), and the master/slave option enables up to 10 cylinders to communicate within an interconnecting two-core cable. The additional option of a room distribution unit is available for both LE and LEP models up to 45 Kg/hr and would be ideal for applications where AHU/ducts are unavailable. This can be supplied either fixed to the humidifier or loose for remote mounting directly into the room.
