Being energy-conscious and environmentally responsible has had a tremendous impact in the industry; customers are demanding units that provide maximum performance while remaining extremely energy-efficient. Units today have increasingly complex control panels that manage the many integrated electronic components and devices incorporated within the systems. To manufacture and test these technologically advanced systems requires highly trained and knowledgeable employees. Annexair has always been a technological leader in the industry; we continuously adapt our manufacturing and testing processes as well as hire and train competent employees, which is reflected in every product we build. We are one of the only manufacturers in North America with the capability of testing all types of units built, no matter the size. When testing water source heat pump units, a special factory closed-loop system that uses a 4,000 gallon underground water tank is connected to the tested unit. A technician will adjust water flow (gpm) to match that exact project requirements while testing the unit. An in-depth verification of the unit is performed to guarantee a problem-free field start-up. From a simple ERV to a complex Dual-wheel configuration equipped with a water source heat pump system, every unit we build is completely and thoroughly tested prior to shipping. Our testing procedures include unit functionality, operation and refrigeration performance, based on the operating sequence. All of our air-cooled condensing units are also tested to ensure successful field start-up. At Annexair, we are always focused on exceeding customer expectations and therefore rigorously update our unit testing policies and procedures. A delivered unit is a tested unit.
