Licensed Mechanical Engineer Supports Restaurants with Ventilation Exemption Letters

Glew Engineering Has Successfully Helped Several Restaurants Obtain Ventilation Exemptions

A Silicon Valley Engineering firm, Glew Engineering Consulting, located in Mountain View, Santa Clara County, California, assisted several restaurants obtain their Health Department certificate by writing Exhaust Ventilation Exemption letters.  Glew Engineering provides engineering services for computer aided design (CAD), finite element analysis (FEA) and for heating ventilation and air conditioning (HVAC) systems.  Typical customers have included K’s Crepes, (Crepe Maker) Crepes and More (small oven), and Mercado La Torre (tortilla Maker.)  In some instances, it was necessary to work with clients to identify kitchen equipment that met the Ventilation Exemption requirements.  In all cases, the clients were able to successfully obtain the Health Department Ventilation Exemption approval.
