TLV DC7 is a welded-unit construction cyclone separator that uses centrifugal force to separate condensate from steam or air in piping lines. This cyclone separator is suitable for use in process applications that require high-quality steam or air up to 2.5 MPaG (355 psig).

WARNING

Do not use for toxic, flammable or otherwise hazardous fluids. This product is a separator for steam or air that separates condensate from steam or air piping systems. Use only for steam, air and/or condensate.

Pressure Loss (Steam)

The pressure loss chart is based on a steam pressure of 10 barg. For other pressures, multiply the steam flow rate by the correction factor given in the table below. Use this value on the pressure loss chart.

Proper Installation

1. Before installation, be sure to remove all protective seals from the product.
2. Install the separator at the point on the piping where condensate is generated and the separation of condensate will have the greatest effect on efficiency. For example, on a main or branch at the inlet of equipment requiring high-quality dry steam or air.
3. Before installing the separator, blow out the inlet piping to remove any piping scraps, dirt and oil. Close the inlet valve after blowdown.
4. Install the separator so the arrow on the product is pointing in the direction of steam or air flow.
5. The separator should be inclined no more than 10° horizontally and front-to-back as shown below.
6. Install a steam trap or an air trap at the condensate outlet. Use of the TLV Free Float type trap is advised.
7. To facilitate inspection and maintenance, install a union at the condensate outlet and ensure that there is sufficient space for maintenance.
8. Open the inlet valve and outlet valves and check to make sure that the separator functions properly.

Allowable Inclination

Troubleshooting

If the expected performance is unachievable after installation of the separator, read the Proper Installation section again and check the following points to take appropriate corrective measures.

Problem	Cause	Remedy
Condensate is mixed in with the steam or air from the separator outlet	Flow velocity is too high	Compare the specifications and actual operating conditions, and take steps necessary to lower the flow velocity
Condensate is mixed in with the steam or air from the separator outlet	Improper installation	Correct the installation
