PCS-3000 Proofer Control System
Eliminate Proofer Temperature & Humidity Problems Forever! Designed for retrofitting your existing proof box
or fermentation room, the Cooke PCS-3000 state of the art control system eliminates all of the problems
associated with wet/dry bulb control systems.
• Maintenance is virtually eliminated.
• Better product quality and consistency.
• Reduced product waste & lost production.
• Closer control reduces fuel consumption.
• Eliminates unnecessary sling psychrometer checks.
• Troublesome start up condensate is prevented by a built in humidity lock out feature.
Your Plant Electrician can easily install the PCS-3000 following these three simple steps:
1. Drill a 1/2" hole through the side of the return duct and mount the combination temperature/humidity
sensor using only two screws.
2. Mount Nema 4X control box at any convenient location, connect AC power and pre-wired sensor cable.
3. Install four control wires from terminal strip in control box to control valves.
You're proofing in a matter of minutes! Leave your old system in place and run it parallel with the
PCS-3000 for a short time. This will allow production personnel to become acquainted with direct
RH readings rather than interpolating from a psychrometric chart. The PCS-3000 is maintenance
free and flexible. It can be field wired to control solenoid valves, proportional pneumatic or electric
motor actuated valves. You can easily add a recorder at any time.
