Dry Running Design --YTS-1:

YongHua's YTS-1 has successfully contained emissions and performed as a safety/backup seal in flashing hydrocarbon services and volatile organic compounds. As a result of its dry- running design, it provides a reliable and economical alternative to dual seals with liquid barrier systems.

Dry-Running Design Eliminates Liquid Barrier Systems!

Through the use of a specially designed bellows assembly and optimal face materials, the YTS-1 has proven itself through years of continuous service as a reliable dry-running seal, eliminating the need for liquid lubrication!
As a result, the following are eliminated:
 High initial costs of the barrier tank
 High initial costs of related system components
 Cost of barrier fluid
 Cost of cooling water
 Cost of long-term maintenance
 Seal failures resulting from barrier system operational problems
 Hazardous waste disposal issues of contaminated barrier fluid
Simple and Versatile Design
The YTS-1 is designed as a self-contained cartridge. When used with a standard YongHua primary seal, the YTS-1 requires less axial space than typical dual seal arrangements. The YTS-1 can be used with either a rotating or a stationary primary seal of a bellows or a pusher design.
High Temperature Applications
For applications above 2040C (4000F) , such as gas oils and heat transfer fluids, the YTS-1 is available in a high temperature design with Grafoil. or Kalrez. packings. In these applications, the YTS-1 will provide an additional level of safety during process or system upsets without the need for liquid lubrication typically used with liquid tandem seals.
Low Temperaturere Applications
For applications below 2040C (4000F) , the YTS-1 will contain any nominal leakage from the primary seal and act as a backup, providing an additional level of safety during process or system upsets. The YTS-1 is an effective solution to meeting emission requirements in flashing hydrocarbon services, such as propane, butane, and ethane, where the specific gravity is less than .600.
To maximize emissions containment, it is suggested that the gland cavity be vented to a vapor recovery system as shown in the piping schematic on the back of this brochure.
