Thermal Wheel HRU
Heat Pump DX Control
Procter and Gamble are a multinational corporation headquarterd in Ohio, USA.
We were requested to provide our controls to 2 large Air Handling Units controlling the supply air into a Laboratory Booth.
The iSmart controls package we proposed, managed both the Direct Steam Humidifier, the cooling coil engaged for both cooling and dehumidification processes as well as the heating coils responsible for taking the air at a very constant flow.
We were challenged with providing an extremely close level of constant control for the supply temperature and humidity levels. Following an on site commissioning in Ohio, the system proved to be maintaining the accuracy of 0.2°C and 2%RH
