Intake Air Humidity Control System

Intake Air Humidity Refrigeration Unit

Intake Air Humidity Control System Unit is equipped with a adjustable refrigeration system replacing the “ice tower” previously used for chilling and dehumidifying intake air to research and motor method cfr octane engine.

The air control system is connected through the humidifier tube to the carburetor for regulating the moisture content of intake air into cfr octane engine at a constant 25-50 grains of moisture prescribed of dry air as specified by ASTM D2699, ASTM D2700, ASTM D2885.Intake air humidity control system for cfr octane engine

Intake air humidity control refrigeration system

The Refrigeration System

is equipped with a separate stainless-steel reservoir of 10-liter refrigerating liquid.
The temperature range of the cooling fluid could to be from ambient temperature to -10°C with the stability of 0.5°C. The refrigerating temperature and refrigerating time are adjustable, using a digital control panel.
intake air control cooling circulation system

The Cooling Circulation System

 is equipped with a pump to circulate the cooling fluid to octane engine’s carburetor and to sample fuel bowl which needs chilling.
Plastic hoses are used for connecting to the carburetor by the quick disconnects couplings for cooling the sample fuel bowl. This circulation system includes a condensate pan and drain line.
intake air humidity control panel

The Temperature Control Panel

includes a main power switch, a pump power switch, a refrigerating time adjust-key and a digital display for temperature controller.
The equipment comes with sound-light alarm, when it’s lack of cooling liquid.
