Direct Gas-Fired MUA: We install and service TSSA-approved MUA units that heat freezing sub-zero outdoor air to a comfortable 20°C before bringing it into your kitchen.

Air Balancing: Maintaining an 80%-90% airflow replenishment to keep a perfect indoor pressure.

Technical Features & Selection

1)CFM Matching ：According to NFPA 96 and Ontario Building Code (OBC), the make-up air volume typically needs to reach 80% to 90% of the exhaust air volume (to maintain a slight negative pressure in the kitchen and prevent cooking fumes from entering the lobby).

2)Interlock System( )：Emphasis is placed on coordinated control. When the exhaust fan is turned on, the MUA automatically starts; when the exhaust fan is turned off, the MUA automatically turns off.
3)VFD - Variable Frequency Drive ：It supports automatic adjustment of air volume based on the intensity of cooking in the kitchen, helping the owner save electricity and gas.
