GGS performs testing with the NDT technology that is best suited for ammonia refrigeration systems. This results in a non-disruptive experience that yields better data for peace of mind and decision-making.
Our services are employed across the U.S. by refrigeration and PSM managers, engineers, contractors and consultants of food and beverage and cold storage facilities.
