Application Spirax Sarco flash condensing deaerator heads are ideal for boiler feedtank applications. They are suitable for both new and retrofit applications. Each head is fitted with a connection for air vent and recirculating feedwater spray nozzle. The air vent is for the immediate venting of liberated gases (the connection should also include a vacuum breaker). For further details on the RFS recirculating feedwater spray systems see separate literature.
