Statement of Work

Bed Bug Oven

Topeka VA Medical Center

Bed bug treatment oven to kill 100% of bed bugs in all life stages, including eggs, nymphs and adults:

Inside self-contained heating cabinet needs to be at least 70"H x 34"W x 22"D.

Unit shall be mounted on casters.

Allow the preprogramming of digital controller with a low temperature (120 degrees) and high

temperature (150 degrees) cut off limits and a set point of 130 degrees.

Bed Bug Oven needs to be designed to kill bedbugs using a heat treatment cycle of 130°F ± 5°F

for a period of 30 minutes.

Oven will need to be designed for a single phase, 120/24OVAC, 20A power feed.

One 240 VAC, 1700W resistive heater is protected by a two pole 10A circuit breaker and two safety thermal switches wired in series.

The temperature of the oven needs to be controlled by a temperature controller in the PLC with a preset temperature set point of 130°F and uses ON/OFF control to reach and maintain the set point.

The feedback transducer to the controller needs to be a Type K thermocouple.

The temperature controller needs to be controlled by the airflow temperature of the oven and

set to a maximum temperature of 170°F.

The fan and control electronics need to be powered by 120 VAC through a 1A and 2A circuit breaker, respectively.

The fan needs to be configured to remain on after the cycle is complete and turn off when the door is opened, or the "STOP/RESET" pushbutton is pressed.

The cycle timing of the heat treatment cycle needs to be initiated when the probe temperature

of the items being treated reaches and maintains 130°F.

When the heat treatment cycle is complete the resistive heaters need to shut off and have a completion indicator.

A spare parts package to consist of 1 each: heater element, thermocouple, over-temperature switch, solid state relay and fan unit.
