We build custom Controls for Refrigeration, heating, wine Tanks and Barrel Rooms across Sonoma and Napa counties, so you can check temperatures, adjust setpoints and get alarms from anywhere.
Our in-house team designs, builds, programs and installs Control Panels, then trains your team to use them.
You can see equipment status and temperature history in your browser, and get email alerts when something changes.
Problem: A glycol Pump Drive was not responding correctly in manual or automatic.
Repair: A pressure input was stuck at the wrong reading. We moved the pressure signal to another Drive input and set the Drive to control on pressure in automatic and on speed in manual.
Verified outcome: Correct pressure reading confirmed. Manual and automatic modes tested.
Problem: A Tank’s glycol Solenoids were not working correctly.
Repair: We found a loose connection at the cold glycol supply Solenoid and the warm glycol return Solenoid wired in place of the cold return. We remade the connection and corrected the wiring.
Verified outcome: Heating and cooling modes tested, with the correct Solenoids opening and closing.
A sensor in each Tank or room feeds a controller that opens glycol Solenoid Valves to cool or heat until it reaches setpoint. Barrel Rooms add humidity, CO2 ventilation and night-air cooling. We design, build and program these Control Panels in house.
It lets your team see Tank and room temperatures, equipment status and temperature history from a browser, and sends alarms when something goes out of range.
Yes. The browser access works on a phone, so you can check temperatures and change setpoints from anywhere, and alarms go out by email.
A blank display usually means a power or Transformer problem, often from moisture. A wrong reading points to the sensor or its wiring, and a display that reads fine but won’t cool points to the Solenoid or its wiring. We test each part of the chain.
It’s usually sensor location, a failing sensor, wiring or a calibration offset. We compare readings under steady conditions before recalibrating or replacing anything.
Usually it’s a glycol Solenoid Valve sticking open or wired wrong, a sensor placed where it reacts slowly, or control settings that are too aggressive. We check the Valve and sensor first.
We’ll follow up to confirm the details and schedule a visit.
