RETRIEVER I—Steam Only —Operating Principles
2
The Retriever I: Purpose
The purpose of the RETREIVER I for Steam Only is to recover heat and steam
remaining in condensate returns in order to generate hot potable water.
The Retriever I: Sequence of Operation
1. When hot domestic water is drawn from the Retriever I, incoming cold water
replaces it and the temperature decreases.
2. When the temperature dips
below
the set point on the control, the steam solenoic
valve will open and reduced-pressure steam will enter the Retriever’s coil.
3. When the temperature of the water in the tank reaches the set point, the steam
solenoid valve will close. No steam or will circulate through the coil.
4. The vinyl and polyurethane insulation jacket allows less than 1/2 degree per hour
standby loss.
Frequently Asked Questions
Q: Do I need steam traps on the heat exchanger outlets?
A: The surface area of the Retriever’s coil is oversized for most applications in
laundries and Drycleaning plants. Steam traps are usually not necessary because all
of the steam will be condensed upon exiting the coil.
