Inverted bucket steam trap - ER25 | Miyawaki

The Inverted Bucket Steam Trap ER25 by Miyawaki is a reliable and efficient steam trap designed for industrial applications. It operates on the inverted bucket principle, which ensures effective removal of condensate while minimizing steam loss. The ER25 model is known for its durability and robust construction, making it suitable for high-pressure and high-temperature environments. Its design allows for easy maintenance and long service life, contributing to improved energy efficiency and system performance. Ideal for use in steam systems, the ER25 helps maintain optimal operation by preventing water hammer and ensuring proper drainage.

Description

1980 Received the Award for Excellence in Energy Saving

Features

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.

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).

Easy maintenance

For quick and easy maintenance, this model can be repaired directly in line.

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.

*’SCCV System’ is an abbreviation of Self Closing and Centering Valve System.

Typical applications

Suitable for use in a wide range of fields including the plant industry, foodstuff manufacturing, dyeing, cleaning, and air conditioning.
