Pressure reduced

Following the successful RIGHT CHEMISTRY installation and trial of a TLV Euro Engineering steam pressure reducing system at its Sturminster Newton site two years ago, linen hire and laundry specialist Johnsons Stalbridge Linen Services has installed seven additional systems at three more sites.

Each of the four laundries uses steam for roller ironers, through which linen is passed for drying and ironing. Steam is generated at approximately 10 bar, which is ideal to heat the ironers to the temperature required for cotton-based linen products.However, in recent years more syntheticbased linen products necessitated a reduction in steam pressure to approximately 6 to 8 bar to give them the lower temperature required for these materials.

TLV engineers recommended the combined valve, trap and separator arrangement of its CV-COS coupled with a pressure sensor and controller on the steam branch line immediately before the roller ironer. The CV-COS automatically controls pressure, temperature or the flow rate of steam; and removes condensate at a separation efficiency rate up to 98%. The electropneumatic pressure reducing valve adds a convenient control function to a range that already combines a pressure reducing valve, separator and steam trap in one compact unit.

The specification is said to save space, simplify system layout, piping and maintenance, and eliminate the risk of damage and incorrect adjustment.
