The AS-20 is a complete anti-sweat door heater control system: a patented controller, two purpose-built sensors, a wireless gateway, and the Case Manager cloud - co-developed with one of the world's largest glass-display-door manufacturers and engineered for easy retrofit.
The controller reads both sensors, applies the decision rule, and intelligently cycles the door heaters case-by-case - logging every state change and sensor reading, 24/7.

Instead of running heaters around the clock, the AS-20 knows the exact moment condensation could form - and acts only then. This is dew point control done right.

Reads the aisle-facing air to find the dew point - the temperature at which condensation will form on the glass.
Reads the heater-surface temperature, so the controller knows exactly how close it is to the dew point.
Every reading is stored off-site and available in real time through secure cloud servers. Log in from anywhere to fine-tune performance, run M&V, and catch failing equipment before it becomes a crisis.
Case & frame temperatures, humidity and dew point, logged continuously.
Energy saved per case and total dollars saved - documented for M&V.
Case & temperature alarms sent straight to your phone or email to prevent spoilage.
The CommZ gateway feeds your existing EMS/BMS over industry-standard protocols - so the AS-20 drops into the systems you already run.
