Surge Systems

Lockwood Surge Systems are packaged, atmospheric-pressure, storage tanks built for commercial or industrial steam systems. Surge tanks provide a location where condensate and makeup water can mix before it reaches the deaerator. This results in a more even inlet temperature and smoother operation. A surge tank is recommended when the condensate returns exceed 50%.
