Idle Energy Rate
Following the preheat period, the steamer was left in the “On” mode and
allowed to stabilize for one hour. Then, the steamer was placed in its
“idle/hold” mode and the energy consumption was monitored over a 2-hour
period and the idle energy rate was determined to be 0.2 kW.
Test Results
Rated energy input, preheat energy and idle rate test results are summarized in
Table 3-1. The Vortex had a preheat time of 17.0 minutes and exhibited a idle
rate of 0.2 kW.

The steamer was tested using two different food products (green peas and red
potatoes) under two loading scenarios—heavy (6 pans) and light (single pan).
All cooking scenarios were conducted in the unit’s “On” mode.
The Groen Vortex steamer does not employ a separate boiler, water
connection or drain. Four gallons of water were poured into the reservior at
the bottom of the cooking compartment before testing began. The steamer was
emptied at the end of the day, as directed by the manufacturer’s instructions.
