Features
No condensate logging on primary side
Intermittent or continuous discharge depending on condensate loads means no condensate stacking up on the primary side.
Easy maintenance
For quick and easy maintenance, this model can be repaired directly in line.
Complete steam containment
A double steam separation mechanism (implemented with a U-shaped duct and inverted bucket) provides reliable steam separation and ensures trap tightness.
Superb durability
Offers superb durability thanks to the SCCV System valve and robust super lever, as well as stainless steel internal components.
Condensate recovery
With its high degree of back pressure tolerance, this model supports condensate recovery at pressures up to 90% of the upstream pressure.
Free from steam and air locking
This model is free from steam and air locking due to a small air vent hole in the top of the bucket (discharges hot air and non-condensable gases).
*’SCCV System’ is an abbreviation of Self Closing and Centering Valve System.
Typical applications
Suitable for a wide range of applications including industrial plants, food and beverage, dyeing, and cleaning.
