TTRA’s focus is refrigeration; design, installation, service and maintenance of industrial and large commercial refrigeration systems. Key sites include manufacturing processes, ice rinks, pharmaceuticals, food/beverage, industrial chemicals and other products. We are specialists in the use of natural refrigerants, such as ammonia and CO2, but we are also passionate about working with synthetic refrigerants and secondary refrigerants, such as glycol and chilled water. With offices in Sydney, Griffith and Newcastle, we offer market leading service backed by knowledge gained over decades of industry experience to meet and exceed our customer requirements. We also can offer Ammonia Awareness Training for staff and Auditing of customer sites.
